Dhaka city is experiencing tremendous growth in traffic. Until recently, the city's demand for traffic was entirely served by public buses, a mix of motorized and non-motorized paratransit, and private personalized transport. The first ever rail-based metro, mass rapid transit (MRT), namely MRT Line 6, was partially inaugurated on 28 December 2022. Authority expects that there will be visible modal shift. However, MRT systems in many Asian and European countries are attracting much lower private motorists than what is expected. Moreover, in Dhaka, a unique mix in road-based transport with public transit and varieties of paratransit and private personalized vehicles intensifies the uncertainties involved in modal shift. Therefore, based on a field survey done before four (04) months of the partial inauguration of MRT Line 6, this study intends to explore the modal shift potentials of different mode users to a completely new mode and the modal choice factors. The analysis of the results finds overall, 75% of all mode users are willing to shift, while para and public transit users are comparatively more willing than private personalized vehicle users. However, such willingness comes up with one or more conditions: comfort, reasonable fare, reduced total travel time, less crowd, etc. The study finds that affordability, availability, and accessibility factors have an influence on their modal shift behavior. Also, results from binary logistic model identify significant impact of several sociodemographic, trip- and accessibility-related factors influencing modal shift choice. Findings from this study explain the optimism regarding MRT by different mode users and inform the decision-makers about their course of actions including different interventions, strict and carrot approaches to hold on to the potential shifters and attract more.

E-bikes are recognised as a sustainable mode of transportation with an unmet potential for widespread adoption. However, despite a decade of global implementation, research gaps persist regarding the design and characteristics of incentive programmes for e-bikes and their effectiveness. This review examines different design elements of implemented financial incentive programmes for e-bike uptake in OECD countries. The findings reveal three main components common to these schemes: (1) target cohort, with the majority of programmes focusing on the local population; (2) eligible e-bike types, with regular e-bikes being the most frequently chosen; and (3) financial incentive structures aimed at maximising uptake among the target cohort, with post-purchase rebates being the most prevalent. Another significant aspect identified was the allocation process, predominantly following a “first come, first served” structure. Very few (n = 4) studies included in this review assessed the effectiveness of financial incentives to purchase an e-bike. The variety of designs in these schemes, coupled with a lack of effectiveness assessments and limited evidence, highlights challenges in determining optimal transport policies. In addition to highlighting the knowledge and research gaps, this review synthesises global insights on design elements of financial incentive schemes to boost e-bike uptake, providing a guide of available components of such schemes for programme administrators in designing executive programmes.

Most of today's inland freight transport in Switzerland is operated on the road system. In this study, an innovative agent-based simulation approach is developed to investigate the potential shift from road to rail. In a first step, future freight demand for inland road transport is calculated based on official governmental forecasting tools provided by ARE (Bundesamt für Raumentwicklung, Switzerland). In a second step, the agent-based simulation framework Multi-Agent Transport Simulation (MATSim) is used to investigate different supply concepts and estimate the mode shift effect from "road-only" to "intermodal road and rail transport". The simulated transport supply consists of the road network, the rail network, the cargo rail schedule, and the terminals where containers are loaded from Heavy Goods Vehicles to cargo trains and vice versa. For both, the road and rail system, dynamic queuing effects are explicitly taken into consideration. The illustrative case study for Switzerland reveals that intermodal road/rail transport provides a great potential to reduce road traffic. From the users' point of view, switching from road to intermodal transport yields an average cost reduction of 46%. Even without any optimization of the transit schedule and terminal capacities, a significant trip share of 23% is shifted from road to intermodal transport. Both train and terminal capacities as well as the number of train departures per origin destination relation are limiting factors and have a crucial impact on the demand for intermodal transport.

Abstract Background The processes of transport decarbonisation are complicated. In this paper, we adopt the Activity-Modal Share-Energy Intensity-Carbon Intensity of Fuel (ASIF) approach and propose a conceptual framework on the direct and indirect impact of COVID-19 on transport CO2 emissions. In the Chinese context, changes of carbon emissions associated with passenger and freight transport (including urban, rural, and inter-city transport) across different transport modes are estimated. Scenario analysis is then used to estimate the impact of COVID-19 on total transport carbon emissions up to 2030. Four scenarios, from minimal to significant behavioural changes and global recession associated with COVID-19, are generated. Results Under the pandemic, the transport system in China was estimated to have produced 28% less CO2 emissions (1044.2 Mt) in 2020, when compared to 2019. Compared with the business-as-usual scenario, the estimated total transport carbon emissions in 2030 would drop by 6%, 15%, and 21% and 23% under the minimal-impact, low-impact, moderate-impact, and severe-impact scenarios, respectively. Conclusions The results suggest that the processes triggered by COVID-19 alone will not be sufficient to meet the ambitious transport decarbonisation targets. To meet China’s pledge under the United Nations Framework on Climate Change, the medium-term effects of COVID-19 must be combined with strong transport decarbonisation measures of modal shift and new energy applications. With these additional measures, it may be possible to advance the transport carbon peak before 2030. Lessons are relevant to other developing countries.

Abstract Background Encouraging alternatives to the car such as walking, cycling or public transport is a key cross-sector policy priority to promote population and planetary health. Individual travel choices are shaped by individual and environmental contexts, and changes in these contexts – triggered by key events – can translate to changes in travel mode. Understanding how and why these changes happen can help uncover more generalisable findings to inform future intervention research. This study aimed to identify the mechanisms and contexts facilitating changes in travel mode. Methods Prospective longitudinal qualitative cohort study utilising semi-structured interviews at baseline (in 2021), three- and six-month follow up. Participants were residents in a new town in Cambridgeshire, UK, where design principles to promote walking, cycling and public transport were used at the planning stage. At each interview, we followed a topic guide asking participants about previous and current travel patterns and future intentions. All interviews were audio recorded and transcribed. Data analysis used the framework approach based on realist evaluation principles identifying the context and mechanisms described by participants as leading to travel behaviour change. Results We conducted 42 interviews with 16 participants and identified six mechanisms for changes in travel mode. These entailed increasing or reducing access, reliability and financial cost, improving convenience, increasing confidence and raising awareness. Participants described that these led to changes in travel mode in contexts where their existing travel mode had been disrupted, particularly in terms of reducing access or reliability or increasing cost, and where there were suitable alternative travel modes for their journey. Experiences of the new travel mode played a role in future travel intentions. Implications Applying realist evaluation principles to identify common mechanisms for changes in travel mode has the potential to inform future intervention strategies. Future interventions using mechanisms that reduce access to, reduce reliability of, or increase the financial cost of car use may facilitate modal shift to walking, cycling and public transport when implemented in contexts where alternative travel modes are available and acceptable.

In most urban areas, mobility is predominantly reliant on automobiles, leading to significant negative environmental impacts, such as noise pollution, air pollution, and greenhouse gas emissions. To meet the objectives of the Paris Agreement, urgent action is required to decarbonize the mobility sector. This necessitates the development of assessment and planning tools to create effective decarbonization scenarios. Urban mobility must evolve to reduce dependency on fossil fuels by increasing public transport options and promoting active modes of transportation. This research presents a methodology to estimate the modal share required to shift car users to active modes and public transport, thereby achieving future CO2 emission reduction targets in the road transport sector. A case study in Braga, Portugal, demonstrates that to meet the 2040 target of 59,150 tons of CO2, 63% of trips must be made using active modes (e.g., walking and cycling) and 32% by public transport.

EU recently decided to include shipping, meaning all intra-European shipping and 50% of extra-European voyages, in the EU Emissions Trading System (ETS) beginning in 2024. This article provides an early assessment of the impacts of the EU ETS on the shipping sector's potential reductions in greenhouse gas emissions for different types of ships. It further examines selected mitigation measures and the impact on modals split and costs. The study employs a mixed-methods approach combining quantitative estimates (based on data from the EU monitoring, reporting and verification system) with qualitative data and information from interviews with key actors and from previous literature. This approach aims to provide a comprehensive understanding of the impacts of the EU ETS. The inclusion of shipping in the EU ETS is expected to introduce significant incentives to reduce emissions. We estimate that switching to bio-methanol at an emissions allowance price of €90–100/tCO2 will be cost-effective for a minor share of shipping segments (representing about 0.5-5% of all ships), whereas at a price above €150/tCO2 it could be cost-effective for a considerable share (potentially 75%) of ships. In the short term, the costs incurred by the EU ETS will be passed on to transport customers as a surcharge. The increased cost may, unless properly addressed, drive carbon leakage. Meanwhile, a modal shift away from shipping may occur in the roll-on, roll-off (RoRo) and roll-on passenger (RoPax) segments due to direct competition with road and rail transport and the relative ease of shifting to other modes of transport. Integrating shipping into the EU ETS is an important step towards reducing GHG emissions in the sector but also will reduce emissions of NOX, SOX, and PM. CO2 emissions from shipping constitute about 8% of GHG emissions from all sectors in the EU ETS. The need to purchase allowances will increase operating costs, which will initially be passed on to transport customers as a surcharge. Interviews confirm that a modal shift away from shipping to road and rail may occur in the RoRo and RoPax segments. Switching to bio-methanol may be cost-effective mainly for some ships in the RoRo, RoPax and reefer segments at an allowance price below €100/tCO2, while for most ships (about 85–100% of ships) it will be cost-effective above €200/tCO2.

The railway infrastructure projects in Thailand aim to shift transportation from roads to railways. This is crucial for transporting goods in emerging economies and increasing the demand for rail freight transport. However, several dynamic uncertainties hinder sustainable rail freight transport in Thailand. This study aims to identify the key factors and validate their effects on the success of the modal shift from roads to railways in Thailand. A total of 200 participants filled out a questionnaire delivered online and via postal service. The key factors were categorized into the following categories: the rail freight transport system, demand, and development factors in Thailand. The inter-relationship and connection of these factors were analyzed using SEM (structural equation modeling). The SEM results showed that all causal factors in the model had a positive influence on rail freight development in Thailand, which explained 98.3% of the variance in the factors influencing development. This study's findings underscore the influential significance of rail performance, rail infrastructure, the legal framework, pricing, mode choice, and technology on the expansion of rail freight transport in Thailand. The rail freight transport system, rail performance, rail infrastructure, and Thailand's rail infrastructure development strategy were significant direct predictors of rail freight expansion. An expansion of the rail freight transport system also leads to rail freight demand. The results of this study have positive implications for the government, railway practitioners, and policymakers to prioritize their focus on achieving rail freight transport as the national target.

This white paper presents the synthesis of the literature on the use of cargo bikes for urban goods movement with a particular focus on four barrier and opportunity domains: physical and spatial; economic; political and legal; and social and cultural. It also includes research particularly relevant to California cities, although many of the studies reported were conducted outside California because we found a lack of evidence within California. The barriers to shifting from trucks and vans to cargo bikes for a variety of good movements remain tall in California. They include, among many, a need for a significant shift in the delivery landscape that requires collaboration across different organizations, and support from the local and state level that includes the development of urban consolidation hubs, investment in bike infrastructure, and strict restrictions on larger delivery vehicles. In addition, it may also require initial incentives to freight operators to offset the costs of shifting to cargo bike logistics. Although the barriers are large, the need is paramount, given the rise in e-commerce and local goods movement. Motivated by this need, and with targeted efforts to overcome these barriers, synergistic benefits are possible including a safer and more bike-friendly road network supportive of both personal active transportation and cargo-bike goods movement. These outcomes will help achieve wide-ranging goals in transportation planning, including GHG reduction, improvements to public health through physical activity, and emission reductions, among others.

The air quality in many German cities does not comply with EU-wide standards. Vehicle emissions, in particular, have been identified as an important cause of air pollution. As a result, driving bans for diesel vehicles with critical pollutant groups have been imposed by courts in many places in recent history. Against the backdrop of the growth of major German cities over the last few years, the question has become whether and how a change in the modal split in favor of more environmentally and climate-friendly public transport sector can be achieved. The Federal City of Bonn is one of five model cities that is testing measures to reduce traffic-related nitrogen dioxide emissions through a Climate Ticket as a mobility flat rate for one year for 365 €, which is part of the two-year ''Lead City'' project funded by the federal government. A quantitative survey (n = 1,315) of Climate Ticket users as well as the logistic regression carried out confirm that a change in individual mobility behavior in favor of public transport is possible by subsidizing the ticket price. The results show that individual traffic could be saved on the city's main congestion axes. In order to achieve a sustainable improvement in air quality, such a Climate Ticket must be granted on a permanent basis, with a well-designed mobility offer and must be generous in terms of the group of authorized persons and the area of validity.

The City of Tshwane has been undergoing rapid urbanisation, resulting in increased daily mobility enabled by motorised individual transport, potentially causing adverse environmental and public health effects. In light of this, promoting a modal shift towards sustainable transport modes has become a key priority for reducing the negative externalities associated with using motorised individual transport in the City. This study aimed to examine the perceived effectiveness of planned measures of modal shift to encourage the adoption of sustainable transportation modes, including public transport, cycling and walking, in the City of Tshwane. The study sought to determine the extent to which such interventions can reduce dependence on cars and mitigate the environmental impact of transportation. A questionnaire was used to collect data from 418 residents, revealing that the most effective interventions perceived to promote public transport usage were "more reliable public transport, more bus routes, and cheaper fares". Personal safety and security were the main concerns for cycling, while improved walking infrastructure increases the likelihood of walking for short distance journeys. The study concludes that substantial investment is necessary to improve transport infrastructure and increase usage of alternative transport modes to motorised individual transport and suggests future research examining the feasibility of bicycle rental facilities around the city centre.

The transport sector accounts for approximately a quarter of the EU's total greenhouse gas emissions, with freight transport alone accounting for about one-third of the overall transport-related emissions. Mitigating the sector's environmental impact is crucial for tackling climate change and achieving sustainable development goals. Modal shift is one of the main solutions to address this challenge; however, many companies have yet to realize its full potential. This paper presents a survey conducted in the Flanders region of Belgium, aiming to identify the challenges and barriers faced by industry players in this key geographical area and to explore the reasons behind the limited implementation of synchromodal transport among them. The survey evaluates the current state of synchromodal transport adoption and offers valuable insights for policymakers and industry stakeholders aiming to enhance sustainability in the logistics sector. The findings emphasize that to overcome the identified challenges, both policy support and the companies' commitment are required. Policy support includes establishing consistent regulations and promoting greener transport modes through providing incentives and technological advancements. This research contributes to the field by examining barriers to the adoption of synchromodality and exploring its application within the context of Flanders. By focusing on this strategic logistics hub, the study provides insights and recommendations tailored to the specific challenges of the region's logistics sector. The challenges faced by industry players in Flanders offer a deeper understanding of modal shift dynamics, facilitating informed decision-making for policymakers and industry stakeholders. Implementing these strategies paves the way for more environmentally friendly, efficient, and integrated transport, benefiting both the industry and the planet. [ABSTRACT FROM AUTHOR]

A modal shift of freight from road to rail and waterborne transport can contribute to reduced negative externalities (mainly air pollution) from freight transport. The purpose of this paper is to identify modal shift public policy instruments in Europe and analyse their performance based on existing ex post evaluations. This analysis identifies 93 public policy instruments, in which 20 ex post evaluations were found. The evaluations mainly consider subsidies/grants at the national level or regulations and directives at the European Union (EU) level. The results suggest that evaluations of subsidies and grants at the national level most commonly describe a positive performance, while several evaluations at the EU level describe a poor or mixed performance. Well-defined targets and simpler application processes are mentioned in several ex post evaluations as suggestions for improving the performance of modal shift policy instruments in Europe.

• This paper reviews factors influencing shift to public transport. • The focus is on developing countries. • The findings highlight a modal shift from motorcycles to public transport. • The findings highlight a theoretical framework for the modal shift. Most studies on commuter and public transport mode choice rely on theoretical frameworks that draw boundaries between the utility function, social-ecological system, demographic and socio-economic attributes, and psychological theory. While models predicting the shift towards public transport are commonly applied in developed countries, there is a lack of similar studies that construct these models in developing countries. In addition, in some developing countries, the motorcycle is one of the main private motorised travel modes. Therefore, the modal shift from motorcycles to public transport in Southeast Asia to reduce private mobility is one of the important topics to examine. This paper presents a systematic literature review, utilising a comprehensive search strategy across electronic databases and reputable sources to identify directed acyclic graphs (DAGs), revealing factors influencing the choice and intention to shift to public transport. Data synthesis from selected studies highlights the intrinsic and extrinsic variables influencing public transport use, motorcycle use, and the modal shift to public transport. The study also proposes a theoretical framework for the modal shift in usage from motorcycles to public transport. [ABSTRACT FROM AUTHOR]

Cities continue to expand along with the growth of population, while our mobility systems often fail to meet the demands for social, environmental and economic sustainability. The second industrial revolution enabled the extensive use of private vehicles, posing various challenges to the sustainability of such systems. Luckily, several best practices aiming at tackling this issue have been identified in the past, facilitating progress towards sustainability. Nowadays, this progress is strongly supported by the call for cities to develop Sustainable Mobility Plans (SUMPS), which stands as an opportunity for best practices to be implemented in coordination with relevant policies. This research identifies the best practices that promote a modal shift, while it investigates their alignment with the strategy that enhances public transport services, encourages active mobility and disincentivizes private vehicle usage. Therefore, the presentation of these practices, introduces a set of initiatives that under aforementioned strategy promotes a modal shift. Furthermore, through the identification of best practices in various locations, several insights and inferences are drawn, providing useful guidance.

The adverse environmental consequences arising from road-based logistics operations have prompted stakeholders, including transport service providers, logistics managers, and shippers, to initiate a modal shift from unimodal road to intermodal railroad (IRR) freight transportation. However, the adoption pace of IRR in developing nations is slow. Modal shift enablers (MSEs) facilitate IRR adoption, while modal shift benefits (MSBs) signify favorable performance outcomes from MSEs' application. The main objective of this study is to rank the MSBs resulting from the adoption of MSEs in IRR freight transportation. This study proposes an integrated multi-criteria decision-making framework utilizing the spherical fuzzy analytic hierarchy process (SF-AHP) to evaluate MSEs' weights and the spherical fuzzy technique for order of preference by similarity to ideal solution (SF-TOPSIS) to rank the MSBs. The case study performed in the Indian logistics sector reveals that 'government policies and legislation enablers', 'infrastructural enablers' and 'strategic and management enablers' are the most significant MSEs, whereas reduction in vehicular pollution and related negative externalities as well as reduction of the freight transport costs including storage and handling charges are most crucial MSBs realized due to adoption of MSEs. A sensitivity analysis is conducted to assess the stability of the ranking. The results help decision-makers in implementing MSEs for MSBs and develop effective IRR adoption strategies. This study also promotes sustainable freight transportation and provides logistics practitioners, researchers, and policymakers with a precise, systematic, and practical decision-support tool. • 36 enablers of modal shift to intermodal railroad (IRR) transport were identified. • 15 benefits realized through adoption of modal shift enablers were recognized. • An empirical case analysis was conducted in the Indian logistics sector. • A hybrid framework of SF-AHP and SF-TOPSIS approach was applied. • It helps stakeholders to understand the key enablers and benefits of IRR adoption.

In view of the huge contribution of transportation to global greenhouse gas emissions, it is imperative to embrace more carbon-efficient transportation modes to support our environmental goals. However, few studies offer empirical evidence to evaluate the potential of shifting transportation model for carbon emissions reduction. This paper, aiming at addressing this gap, conducts an empirical study to assess the CO2 emissions reduction through modal shift from road to waterway transport (MSRW). It utilizes primary data collected from more than 200 voyages of 92 enterprises through one national pilot project on CO2 emission reduction in the Quzhou region initiated by the Chinese central government. Specifically, it employs empirical analysis based on bottom-up methodologies to investigate the potential for CO2 emission reduction through MSRW. The results reveal that MSRW can aid to benefit 45,907 tons CO2 emission reduction from the modal shift within the study scope. When considering factors such as distance and voyage density, it provides new quantitative insights into the advantages of water transport over road transport in terms of CO2 emission reduction under different scenarios. Consequently, this study makes new contributions to the quantification of the benefits that an investigated region/city can derive from transport modal shift. It thereby lays the groundwork for effective cost-benefit analysis and policy implementation toward cleaner transportation. • Use of a hybris of energy consumption approach from a new analysis perspective that consider multiple-dimensional MSRW. • Provide a new research method to enable the quantification of the carbon emissions of an entire transport chain in detail. • Provides a solution to the evaluation of the effect of the implementation of transport policies on carbon emissions. • Investigate the MSRW to stimulate cost-benefit analysis and transport policy implementation towards clean transportation.

With the constant and ever-growing pressure from governing bodies for increased sustainability of transportation systems, the need for changes in the travel behaviours of the inhabitants of suburban and urban areas seems inevitable.Thus a shift from cars to vehicles with higher occupancy rates or other more environmental friendly travel modes needs to be a priority.This requires understanding the reasons why people choose cars as their preferred mode of travel for commutes in order to make informed decisions about how to encourage changes in commuter travel behaviors. This paper presents a case study of four medium-sized Czech towns, including a survey concerning pre- and post-COVID-19 travel habits focused on identifying and understanding the willingness of car-dependent commuters to change their mode of travel choice. This three-stage survey revealed a small, COVID pandemia -based effect on the habits of respondents and helped to identify sensitivities survey participants had to particular travel parameters and characteristics that might be used by municipalities to implement informed policies that could lead to changes in travel behaviours.

an era of increased sustainable transport, the European inland navigation industry has received significant attention to attain sustainable transport. Tremendous opportunities to substantially move freight on waterways are present in the UK; however, several challenges have been appropriately addressed, including infrastructural gaps and various institutional support programs. The paper addresses the UK’s current situation of inland navigation and the key challenges affecting the sectors as a viable alternative transport solution. The article explores and summarises the geographic opportunities, commercial feasibility, and the current condition of the UK’S inland navigation sector. From the practical scenario of the UK’s experience, an attempt was made by the authors to find the critical challenges and issues faced by the industry. The emerging themes from the analysis of this paper indicated governance and leadership issues, cooperation, and coordination mechanism between establishments with various functions and responsibilities, merged with infrastructural investment, are strategic elements for expansion in the UK. Conclusively, the authors presented recommendations for improvement and sustainable development.

Abstract Multimodal Freight Transport (MFT) has been introduced as a solution for reducing the external costs of freight transport while achieving cost improvements. Despite the MFT benefits, its share has been low in practice, and transport by trucks remains the most preferred transport mode. A few works have recently investigated this issue by discussing various barriers to MFT. However, little conceptual work comprehensively examines the barriers that organizations may face during MFT applications. To address this gap, this paper has reviewed 104 studies and identified 31 barriers and possible strategies for overcoming them. To clarify the nature of these barriers, we developed a conceptual barrier framework that positions the identified barriers within the overall MFT chain. This framework categorizes the barriers into six categories: MFT terminal, MFT network, management, regulations and subsidies, delivery characteristics, and interoperability. The findings provide decision-makers and practitioners with theoretical and practical insights into the barriers to transition toward MFT and will assist them in implementing MFT successfully.

Studies show that automated vehicles are likely to increase vehicle travel, resulting in more congestion and greenhouse gas emissions (GHGs). Pricing policies such as increasing the cost of driving and reducing the cost of alternative travel modes could lessen the negative impacts of automated vehicle deployment, although it is unclear to what extent. Cities located in the Westside Cities Council of Governments planning area in western Los Angeles County could be candidates for early deployment of automated vehicles because of their high travel volumes, well-maintained roads, and temperate weather conditions. Los Angeles County also faces high levels of poverty. Thus, the Westside Cities area presents an important opportunity to study how automated vehicles and associated pricing policies might affect congestion, vehicle miles traveled (VMT), and GHGs, and whether they might improve mobility for marginalized populations.Researchers at the University of California, Davis and the Technical University of Berlin evaluated these questions by simulating three scenarios in the Westside Cities area using an open-source, dynamic, agent-based travel model called MATSim. The researchers then calculated the benefits of each scenario compared to the base case for various income groups, considering monetary travel costs and the value of travel time for each income group. This policy brief summarizes the findings from that research and provides policy implications.View the NCST Project Webpage

The research team used the Los Angeles MATSim model to evaluate the travel, greenhouse gas(GHGs), and equity impacts of single-and multiple-passenger automated taxi scenarios, including free transit fares and a VMT tax. The results indicate that automated taxis increase VMT by about 20 percent across scenarios, and automated taxis mode shares more than offset reductions in personal vehicle travel. The automated taxi-only scenario also reduces transit travel by about 50 percent, but the addition of free transit fares reversed this decline and increased transit use somewhat. New empty passenger automated taxi travel compounds the impact of mode shifts in these scenarios and further increases vehicle travel. There is a slight change in mean vehicles speeds across all scenarios. When automated taxis are not battery electric vehicles (BEVs), GHG emissions increase from 16 to 18 percent across scenarios. However, GHGs decline by 23 to 26 percent when automated taxis are BEVs. The equity analysis shows that the automated taxis scenarios provide more accessibility benefits for travelers in three low-income classes than total benefits and benefits for the middle-and high-income travelers. The addition of free transit to the shared automated taxis-only scenario dramatically increases low-income benefits. The VMT tax eliminates almost all of the benefits from the automated taxi and free transit scenarios and creates losses for all three low-income groups.View the NCST Project Webpage

The California Department of Transportation set a goal of doubling walking and transit use and tripling bicycling in the state between 2010 and 2020. However, the most recent comprehensive travel surveys, the 2012 California Household Travel Survey (CHTS) and the California results from the 2017 National Household Travel Survey (NHTS), suggest that the state is moving in the wrong direction. These surveys seemed to show that a smaller share of trips were made by walking or biking in 2017 than in 2012, while private vehicle mode share increased. It is unclear whether the decline represents real changes stemming from various demographic or other factors or is instead related to methodological differences between the two surveys. Researchers at the University of California, Davis used the publicly available 2012 CHTS and 2017 NHTS California add-on data to examine the impact of methodological differences on the changes in mode shares over this five-year period and conducted a preliminary investigation into the role of demographic and other factors in these changes. This policy brief summarizes the findings from that research and provides policy implications.View the NCST Project Webpage

Active mobility projects can potentially initiate paradigm shifts in population and urban planning decision-makers. This paper aims to conduct a social cost-benefit analysis of an active mobility project in a Colombian city. The increase of physical activity, reduction of CO2 emissions, and traffic crashes were measured in an area with suitable slopes to promote bicycles for commuting. A social cost-benefit ratio of 1.14 was found, with physical activity and road safety as the most important outcomes of the active mobility infrastructure. Furthermore, a big room for the increase and promotion of cycling as a mode of transport is addressed.

Abstract Modal shift in freight transport entails moving freight from road to rail, inland waterways, and short sea shipping. In current Dutch and European freight transport policy, modal shift is foreseen to play an important role to mitigate external effects of freight transport. Policy efforts on modal shift are legitimate because the size of the external costs of freight transport are considerable. But can modal shift policies also be effective? In other words, can policy efforts on modal shift result in a decrease of external costs and infrastructure costs due to freight transport? Our research approach falls apart into three steps. In the first step we analyse the transported weight by road on four international freight corridors in North-western Europe that could be transported against at least 10% lower private costs by rail or inland waterways. The share of road transport (transported weight) on the corridors in total road transport in the Netherlands is about 10%. The weight of the cargo that could potentially be shifted on the basis of the transport cost criterium is called the modal shift potential (MSP). We estimate the MSP for the base year 2018 and for the future year 2050. Also in this step, we translate the MSP into changes in transport performance per transport mode. In the second step we determine differences in external costs and user dependent infrastructure costs per unit of transport performance (tonkm) between the transport modes road, rail, and inland waterways. The following external effects are included: greenhouse gas emissions (tank-to-wheel), air pollutant emissions (tank-to-wheel), noise, traffic accidents, congestion, and emissions from fuel and electricity production (well-to-tank) for freight vehicles. Including all these effects, we take a more integral approach than existing studies on the effect of modal shift on the external costs of freight transport. In the third step, we combine the results of steps 1 and 2 and calculate the changes in external costs and infrastructure costs that result from the MSP’s. We find MSP’s of between 35 and 55%, depending on the market segment (container, or non-container transport, and year). These percentages may seem substantial, but we emphasize that on the freight transport corridors rail and inland waterways are (very) competitive to road. Estimates for the decrease in external- and user dependent infrastructure costs if the MSP’s are fully realized point to reductions of €67 million to €150 million for the Netherlands, and €87 million to €136 million abroad for 2018 (considering all countries through which the corridors pass). We emphasize that these are maximum annual savings which can only be achieved if all non-transport cost obstacles for modal shift can be removed. For 2050 estimating a maximum and minimum for the change in external- and infrastructure costs is impossible due to uncertainties in the development of the transport costs and the external costs of freight transport. Because for the year 2018 the MSP’s result in a decrease of external costs and infrastructure costs from freight transport on the corridors, we conclude that in the coming years policy efforts on modal shift can be effective. We can however not conclude anything about the efficiency: are the benefits of policy efforts on modal shift larger than the costs? If that is not the case, taking modal shift measures can eventually not be justified from an economic welfare point of view.

In high-density metropolitan areas prone to air pollution, public transit may be less preferred when air quality is poor due to the difficulty of avoiding outdoor air exposure during their use. By applying seemingly unrelated regression models, we examined the association of particulate matter (PM) with both public transit ridership and, as an alternative to sharing vehicular traffic demands, private car road traffic in Seoul from 2015 to 2018. To control for fluctuations in ridership and road traffic associated with seasonalities such as the day of the week, we used nine-term moving averages transformed into residual form. Results show that higher PM concentration was negatively associated with not only transit ridership, but also road traffic volume and congestion level; yet, the reduction in subway ridership was found to be larger than that in road traffic. This suggests that (1) when PM concentration is severe, people could reduce overall travel rather than change travel modes from public transit to private cars, thus implying that both modes are complementary rather than substitutionary in terms of responding to air pollution; and (2) public transit still seems more susceptible to air pollution than private cars. The findings help us understand the adverse effects of air pollution on public transit use as well as better predict and respond to demand for public transit in poor atmospheric conditions, thereby providing future policy directions for sustainable transportation planning.

Cycling is seen as a desirable modal choice due to the environmental, economic and social benefits to individuals and cities. While North American cities have expanded their targeted infrastructure and programs, cycling still is a marginal mode compared to modal shares observed in western Europe. In an effort to promote a more sustainable transport future, the City of Toronto has highlighted two key policy objectives in the City’s Official Plan for 2050: (i) to ensure that all residents are within one kilometer of a designated cycling route, and (ii) 75% of trips under 5 km are walked or cycled. This paper evaluates the potential for cycling in Toronto considering different cycling vehicles, areas, trip purposes and demographics, and how these change given the presence of cycling infrastructure. Using travel survey data and routing software, we propose a method to analyze the Trip Completion Potential (TCP) of cycling, defined as the rate of completable trips within a 30-minute travel time cutoff and the changes in value given different Levels of Traffic Stress (LTS). Overall, our analysis found that cycling can be a viable transport option for short and medium-length trips for many individuals and trip purposes. However, both the urban form and provision of a convenient cycling network play a vital role, especially in suburban areas, as seen in the decrease in TCP of cycling at different LTS levels. We conclude our analysis by proposing some key guidelines to achieve the objectives defined by the City of Toronto in an equitable manner. [ABSTRACT FROM AUTHOR]

Multimodal Freight Transport (MFT) has been introduced as a solution for reducing the external costs of freight transport while achieving cost improvements. Despite the MFT benefits, its share has been low in practice, and transport by trucks remains the most preferred transport mode. A few works have recently investigated this issue by discussing various barriers to MFT. However, little conceptual work comprehensively examines the barriers that organizations may face during MFT applications. To address this gap, this paper has reviewed 104 studies and identified 31 barriers and possible strategies for overcoming them. To clarify the nature of these barriers, we developed a conceptual barrier framework that positions the identified barriers within the overall MFT chain. This framework categorizes the barriers into six categories: MFT terminal, MFT network, management, regulations and subsidies, delivery characteristics, and interoperability. The findings provide decision-makers and practitioners with theoretical and practical insights into the barriers to transition toward MFT and will assist them in implementing MFT successfully.

There are large disparities in access to green technologies between countries and among different demographic groups within countries. Unless carefully managed, the energy transition risks exacerbating some of these inequalities, for example, by burdening those who are excluded from efficient new technologies with the costs of maintaining legacy infrastructure. The energy transition will create new interdependencies between sectors—for example, between buildings, the power sector, and transportation—requiring integrated design of policies and infrastructure in different sectors. The equitable adoption of new technologies is contingent on broadening access to enabling technologies such as the Internet and payment systems. Decisionmakers must focus on new technologies that remove disparities in access to services but do not replicate current inefficiencies in providing those services (e.g., equitable access to mobility—not only to motorized personal vehicles). Data at higher resolutions and with broader coverage are needed to design equitable technology deployment strategies and evaluate their success. [ABSTRACT FROM AUTHOR]

Bike-sharing systems allow occasional and regular users to travel by replacing other transport modes for the same trip or generating a new journey. Our research assesses the demand for Lisbon's public dock-based bike-sharing system (BSS), named GIRA. This paper aims to identify the determinant factors that influence the potential of the BSS to generate new trips or replace previous modes using a conditional logit model based on a survey of 3112 BSS users. The survey results indicate that GIRA generated approximately 20% of the BSS trips, i.e., they would not have been realized if GIRA did not exist. The remaining BSS trips replaced other motorized (55%) and non-motorized (25%) trips. The main determinants explaining a higher likelihood of replacing different modes are having a yearly GIRA pass and a bike-sharing station within a 5-min walk. In contrast, regular car users are more likely to generate new trips, suggesting they use bike-sharing for recreational purposes. The findings provide policymakers with an assessment of determinants which may influence bike-sharing users to generate or replace trips from other modes and, consequently, define policies to potentially increase bike-sharing.

In this paper, we investigate the conditions that must be met for modal shift (i.e., the transfer of freight transport from road to rail). In addition to describing the competitiveness conditions, the paper makes technical and organizational proposals for rail freight traffic management. One of the most important conditions is that rail-road intermodal freight transport must be competitive in time and price with unimodal road freight transport. The freight transport model presented in this article provides a solution to this problem and an approach to estimating the additional intermodal freight traffic. Another important criterion is the relatively dense network of road-rail links, known as intermodal transshipment points (ITPs) along main railway lines. The proposed model can be compared to the freight transport model described in the term Physical Internet, with the addition that the objective is to minimize road haulage when locating ITPs (or hubs). ITPs are rail-road terminals or, more precisely, transshipment points, which differ substantially from the commonly used continental terminals. The third condition to be met is a horizontal container handling procedure that can be applied efficiently (i.e., at low cost) under the railway catenary and is capable of handling intermodal units used in continental traffic and maritime freight. Finally, an example for the Visegrád countries is presented. The essence of the example is the potential additional freight traffic or modal shift that could be included in the proposed ITP network. We believe that a modal shift could occur for up to 50% of the indicated heavy goods vehicle (HGV) traffic if the offer is competitive. [ABSTRACT FROM AUTHOR]

After three years of COVID-19 lockdown and restrictions, mobility seems to have returned to normality. However, the pandemic has left changes in the mobility patterns of the Madrid Region produced by new trends emerging from COVID-19. This paper analyzes these changes, focusing on the impacts on public transport use, the effects of telematic activities and the influence of home relocation. The basis of the analysis is a survey conducted from November to December 2022, with more than 15,000 valid responses. The results show that public transport lost 6% of trips. These trips have different transfer rates depending on their geographic location. In the City Center, the majority transferred to active modes. However, the car attracted most of these trips in the Metropolitan Ring. These changes in mobility patterns are partly a consequence of the increase in telematic activities. Teleworking has increased by more than 20% in the Madrid Region and has caused changes in trips per week and trip purpose. In addition, teleworking has caused 18% of home relocations to peripheral zones of the region. This paper investigates through statistical analysis which sociodemographic and spatial factors explain the differences in mobility impacts throughout the zones of the Madrid Region.

This study evaluates changes in travel mode shares in California over the period from 2012, when the California Household Travel Survey (CHTS) was most recently completed, to 2017, the most recent implementation of National Household Travel Survey (NHTS). Initial review of the data suggests decreases in biking and walking over this time period. This study explores the factors contributing to this change, namely are these apparent changes the artifact of methodological differences between the analysis of the two surveys, or do they reflect real changes in the travel behavior of Californians? The piece also explores external factors, or changes over time that may contribute to mode share changes, such as demographic shifts or system-wide shocks such as the Great Recession. There are many differences in the preparation of the data used in the analysis across the two surveys; for example, the variables included in weighting are not the same for the CHTS and the NHTS. These differences are not found to have an impact on the outcomes of interest; however, they do suggest the need for more coordination among the NHTS and the CHTS to better enable comparative studies.View the NCST Project Webpage

Current urban mobility systems in Europe, characterized by high car mobility shares, have negative environmental and health impacts but struggle to mitigate these for fear of sacrificing accessibility. Ironically, before the car mobility transition (in the 1950s and 1960s in Western countries and the 1990s in Eastern Europe), most cities were accessible by walking, cycling, public transport, and by the few cars there were. Through a longitudinal case study of a medium-sized urban area in Clermont-Ferrand, France (1950–2022), this paper explores the potential to ‘de-transition’, i.e., to reverse the urban transition process towards ‘accessible, low-car cities’ by reshaping infrastructures to constrain car use whilst accommodating walking, cycling, and public transport. We answer the following questions: To what extent can cities reverse the urban car mobility transition? How could such a process be further encouraged? Our analysis adopts a social practices perspective and uses a mixed-methods approach by combining semi-structured interviews, a survey, and a document analysis. On the one hand, our findings highlight the difficulty of an urban modality shift to car alternatives: (1) the limited reach of public transformation networks (in Clermont-Ferrand, the tramline); (2) the fact that many feel unsafe or assume they need excellent health conditions to cycle, which is associated with leisure and sports; and (3) strong convictions concerning the usefulness of vehicle ownership, which is believed to maximise comfort. On the other hand, based on a historic analysis, we offer practical recommendations to de-transition to low-car urban areas: (1) the creation of an extensive regional tramway network; (2) the development of a full cycling network; and (3) the promotion of an extensive car-free city centre.

Growing population and car dependency in developing countries have led to congestion that adversely affects the environment, travel time, trip cost, accidents, and public transportation reliability. Through implementation of travel demand management (TDM) policies, governments and policymakers aim to reduce private vehicle dependency and encourage people to use public transportation. Light rail transit is an important part of an attractive public transport. Rail transportation systems, though offer many potential benefits, are a major financial challenge for governments because of the high capital and operation costs. Therefore, passenger behavior must be determined before a new system is introduced. Using a stated preference (SP) questionnaire, private car users' behavior in Tehran's universities has been investigated to determine the explanatory factors affecting the modal shift to urban light rail transit (LRT). A binary logit model estimation results showed that men are less likely than women to shift toward LRT because they rely more on their private cars. It was the provision of free on-street parking at destinations and the frequency of using private cars on a weekly basis that had the most negative effect on LRT modal shift, demonstrating the critical role that implementation of TDM policies could play. Moreover, reduction in travel time by LRT has the most positive impact on modal shift toward LRT among private car users. As an interesting finding, marginal effect values indicate that a 10% reduction in travel time (0.32) has a greater impact than the possibility of sitting 50% of the travel time (0.25) on the likelihood of modal shift to LRT. Furthermore, the probability of modal shift to LRT will be reduced by 0.12 units for each unit increase in car ownership. In addition, owning a driver's license was also negatively correlated with LRT modal shift and decreased the likelihood by 0.27. This research will facilitate the decision-making and planning for future transportation systems to increase LRT's utility for potential users.

The railway infrastructure projects in Thailand aim to shift transportation from roads to railways. This is crucial for transporting goods in emerging economies and increasing the demand for rail freight transport. However, several dynamic uncertainties hinder sustainable rail freight transport in Thailand. This study aims to identify the key factors and validate their effects on the success of the modal shift from roads to railways in Thailand. A total of 200 participants filled out a questionnaire delivered online and via postal service. The key factors were categorized into the following categories: the rail freight transport system, demand, and development factors in Thailand. The inter-relationship and connection of these factors were analyzed using SEM (structural equation modeling). The SEM results showed that all causal factors in the model had a positive influence on rail freight development in Thailand, which explained 98.3% of the variance in the factors influencing development. This study’s findings underscore the influential significance of rail performance, rail infrastructure, the legal framework, pricing, mode choice, and technology on the expansion of rail freight transport in Thailand. The rail freight transport system, rail performance, rail infrastructure, and Thailand’s rail infrastructure development strategy were significant direct predictors of rail freight expansion. An expansion of the rail freight transport system also leads to rail freight demand. The results of this study have positive implications for the government, railway practitioners, and policymakers to prioritize their focus on achieving rail freight transport as the national target.

Tactical urbanism is a modality of intervention resulting from citizen initiatives, involving temporary, reversible and inexpensive material transformation, whose objective is to introduce rapid changes in the use and appropriation of urban public space. During or shortly after the spring 2020 lockdown due to the COVID-19 pandemic, tactical urbanism proved to be a simple, quick and inexpensive way to respond to the health emergency of social distancing. In particular, bicycle lanes and paths, referred to as pop-up infrastructures or in France as “coronapists,” were created in order to avoid a modal shift to the car by people afraid of using public transport. Based on research conducted with interviews and video elicitation in five French cities–Grenoble, Lyon, Montpellier, Rennes and Saint-Étienne–with experienced and novice cyclists, the article analyzes how these pop-up infrastructures have been perceived and used according to the context, the type of infrastructure and the profile of cyclists. Building on the discussion of the role of infrastructure, the aim here is to understand how the contingencies arising from the layout of transitory infrastructure produce a different relationship to space and mobility. In doing so, we examine the potential spillover effect of the coronapists on a population that did not practice utilitarian cycling before the pandemic and the continued practice of those who were already utilitarian cyclists. The purpose is to examine how these new infrastructures may have acted as a facilitator of modal shift or as a learning facilitator, and what particular role coronapists played in the practice of utilitarian cycling. The article first examines the reception of the infrastructure and then questions the uses related to an assessment of the cyclability in terms of comfort, safety and security. The article ends with a discussion of the interests and limitations of the tactical dimension in the implementation of coronapists. The diversity of the territory surveyed has shown the political force of the infrastructures and the effect that these transitional infrastructures have had as a complement to other measures. They promote new uses and encourage new people, including children, to adopt cycling on a daily or more regular basis. This result invites the pursuit of this proactive policy. These promising results encourage the development of these infrastructures in sparsely populated, suburban or rural areas. In addition, we have shown that ridership is highly dependent on cyclists’ assessment of the comfort, safety, and security of the path. This perception varies greatly depending on the context, the type of facility and the experience of the cyclists. In most cases, the coronapists have helped to stimulate more cycling by providing greater coverage and safer or more direct routes. The expectancies and dissatisfaction generated by transitional facilities, which relate to perceived bikeability, inform us of the importance of considering the diversity of uses in their design as well as their physical quality and maintenance. The results of our survey encourage the design of readable, wide, physically separated, continuous and maintained facilities to improve cyclists’ sense of safety. Finally, the results also show the importance of thinking about cycling policy by considering the full range of possible uses and experience levels from the design stage onwards in order to attract new cyclists.

Vehicle emissions have been identified as a cause of air pollution and one of the major reasons why air quality in many large German cities such as Berlin, Bonn, Hamburg, Cologne or Munich does not meet EU-wide limits. As a result, in the recent past, judicial driving bans on diesel vehicles have been imposed in many places since those vehicles emit critical pollutant groups. For the increasing urban population, the challenge is whether and how a change of the modal split in favor of the more environmentally and climate-friendly public transport can be achieved.This paper presents the case of the Federal City of Bonn, one of five model cities sponsored by the German federal government that are testing measures to reduce traffic-related pollutant emissions by expanding the range of public transport services on offer. We present the results of a quantitative survey (N = 14,296) performed in the Bonn/Rhein-Sieg area and the neighboring municipalities as well as the ensuing logistic regressions confirming that a change in individual mobility behavior in favor of public transport is possible through expanding services. Our results show that individual traffic could be reduced, especially on the city's main traffic axes. To sustainably improve air quality, such services must be made permanently available.
