- Abstract
Some efforts to address the problem of environmental injustice toward minority and low-income populations include the incorporation of bicycle facilities into an infrastructure. Some well-known positive impacts that come with bicycle facilities are better health, increase in food availability, employment access and ultimately regional sustainability. In order to begin the process of identifying all the other positive impacts that could come with the implementation of bicycle facilities one must estimate how many users these bicycle facilities will attract, in other words, forecast the user demand of these bicycle facilities. This thesis focuses on off-street bicycle facilities and begins by evaluating current and past predictive models that are used for forecasting off-street bicycle facility demand. Noting these past models, we created multiple statistical models from locally sourced data that connect bicycle facility counts to time, demographics, and weather data. Due to the lack in the sheer number of off-street bicycle counters throughout the City of Austin, correlation between demographic and bicycle count data was problematic, yet all three models can in fact be applied to different off-street bicycle facilities only if locally sourced data is acquired.

• Electric two-wheeler (E2W) riders and bicyclists exhibit difference on kinematics and head injury risks in motor vehicle collisions (MVCs). • The difference is resulted from combined influence of initial rider posture, relative geometry and interaction with the two-wheeler. • Head injury risk of E2W riders is lower than bicyclists in representative collisions with the sedan; while comparably higher with the SUV. • Head injury risks of both E2W riders and bicyclists increase with vehicle moving velocity. • Riders with larger statures exhibit higher possibilities to miss first impact of head on the vehicle. Electric two-wheelers (E2Ws) have become newly popular transportation tools with the associated growing traffic safety concerns. E2W riders and bicyclists behave similarly as vulnerable road users (VRUs), while exhibited dissimilarities in riding postures and interactions with the two-wheelers. Existing epidemiology reveals prominent differences in injury risks between E2W riders and other vulnerable road users in collisions with motor vehicles. The objective of this study is to investigate the factors influencing kinematics and head injury risks of two-wheeler rides in two-wheeler-vehicle collisions and compare between E2W-vehicle and bicycle-vehicle collisions. Via multi-body modeling of two two-wheeler types, two vehicle types, and three rider statures in MADYMO, twelve collision scenarios were developed. A simulation matrix considering a range of impact velocities and relative positions was performed for each scenario. A subsequent parametric analysis was conducted with focus on the kinematics and head injury risks of two-wheeler riders. Results show that the head injury risk increased with vehicle moving velocity, while the two-wheeler velocity and relative location between rider and vehicle prior to the collision exhibited highly non-linear influence on the kinematical response. The rider with larger stature had higher possibilities to miss head impact on the vehicle. In collisions with the sedan, E2W riders would sustain lower head injury risks with lower contacting velocity on the windshield than bicyclists. While in collisions with the SUV, E2W riders would sustain increasing head injury risks due to the higher structural stiffness at contact, and the risk level was about the same as bicyclists. The findings revealed the loading mechanisms behind the different head injury risks between E2W riders and bicyclists. [ABSTRACT FROM AUTHOR]

V tej projektni nalogi so sprva predstavljene posamezne vrste kolesarskih površin,njihove lastnosti in uporaba. Predstavljene in ovrednotene so izbrane rešitve kolesarskih površin v mestni četrti Koroška vrata v mestu Maribor. Ovrednotenje kolesarskih površin smo izpeljali s pomočjo točkovanja glede na kriterije. Ovrednotili smo kolesarske površine na posameznih odsekih in mesta križanj ter prehajanj kolesarskih provršin. Ugotovili smo, da so kolesarske površine razmeroma varne, vendar pa v mestni četrti obstaja kar nekaj problematičnih mest. To nas vodi do zaključka, da bo v urejanje kolesarskih površin potrebno vložiti še kar nekaj dela. In this project are firstly presented types of bicycle traffic areas, their characteristics and use. Registered and evaluated are the chosen solutions of bicycle traffic areas in the city district of Koroška vrata in city of Maribor . Evaluation of areas is being executed with the help of criteria. Findings of this work are the bicyle traffic areas assure relativitely good level of security although we can still find some problematic spots. This leads us to conclusion that more work has to be still invested in the infrastructure.

As part of efforts to curb road deaths and serious injuries, the World Bank Global Road Safety Facility (GRSF) invited the International Road Assessment Programme (iRAP) to work with the National Department of Transport Infrastructure (Departamento Nacional de Infraestrutura de Transportes, DNIT) to assess the safety of Brazilian roads. During this second assessment of Brazilian roads, approximately 3,400km of roads were assessed. This technical report describes the road assessment project and includes details on data collection, the methodology used and a summary of the results. The infrastructure-related risk assessment involved detailed surveys and coding of 50 road attributes at 100 meter intervals along the network and creation of Star Ratings, which provide a simple and objective measure showing the level of risk on the road network. The star ratings show that 1 percent of road length is rated as 5-star, 9 percent is rated as 4-star, 58 percent is rated as 3-star, and the remaining 32 percent is rated as 2-star and below for vehicle occupants. For motorcyclists, no roads were rated as 5-star, only 3 percent of road length is rated as 4-star, 47 percent is rated as 3-star, and the remaining 50 percent is rated 2-star and below. For pedestrians less than 1 percent is rated as 4-star and 5-star, 2 percent is rated as 3-star and the remaining 13 percent is rated 2-star and below. For bicyclists less than 1 percent is rated as 5-star or 4-star, 5 percent is rated as 3-star and the remaining 14 percent is rated 2-star and below. The project also involved the creation of a Safer Roads Investment Plans, which draws on more than 90 proven road safety treatments, ranging from low cost road markings and pedestrian refuges to higher cost intersection upgrades and full highway duplication.

- Abstract
Objective The objective of this study was to determine the roadside prevalence of alcohol-impaired driving among drivers and riders in northern Ghana. The study also verifies motorists’ perception on their own alcohol use and knowledge of legal Blood Alcohol Concentration (BAC) limit of Ghana. Method With the assistance of police, the systematic random sampling was used to collect data at roadblocks using a cross-sectional study design. Breathalyzers were used to screen whether motorists had detectable alcohol in their breath and a follow-up breath tests conducted to measure the actual breath alcohol levels among positive participants. Results In all, 9.7% of the 789 participants had detectable alcohol among whom 6% exceeded the legal (BAC) limit of 0.08%. The prevalence of alcohol-impaired driving/riding was highest among cyclists (10% of all cyclists breath tested) followed by truck drivers 9% and motorcyclists (7% of all motorcyclists breath tested). The occurrence of a positive BAC among cyclists was about 8 times higher, (OR=7.73; p<0.001) and 2 times higher, among motorcyclists (OR=2.30; p=0.039) compared with private car drivers. The likelihood for detecting a positive BAC among male motorists/riders was higher than females (OR=1.67; p=0.354). The odds for detecting a positive BAC among weekend motorists/riders was significantly higher than weekdays (OR=2.62; p=0.001). Conclusion Alcohol-impaired driving/riding in Ghana is high by international standards. In order to attenuate the harmful effects of alcohol misuse such as alcohol-impaired driving/riding, there is the need to educate road users about how much alcohol they can consume and stay below the legal limit. The police should also initiate random breath testing to instil the deterrence of detection, certainty of apprehension and punishment, and severity and celerity of punishment among drink-driving motorists and riders.

As part of a long-term partnership between the World Bank and Brazil, the Federal Government of Brazil sought the World Bank’s assistance to review road safety management capacity in Brazil, building both on past experiences in the country and international best practices. This National Road Safety Management Capacity Review, therefore, was prepared by the World Bank, with the support of the Global Road Safety Facility (GRSF). The primary objective of the review is to evaluate the multi-sectoral capacity of road safety management in Brazil, identifying possible road safety challenges and presenting recommendations to address these challenges. The methodology of the review, in accordance with the guidelines of the World Bank Global Road Safety Facility, focused on examinations of key functional aspects of road safety, including institutions, legislation, financing, information, and capacities at all levels of government and among non-government actors. The review was prepared mainly based on interviews of key road safety stakeholders at the federal, state, and municipal levels, members of parliament, NGOs, and the private sector, in addition to direct inspection of roads and on-road behaviors, and the analysis of published research and reports on road safety. In addition, information and understanding gained from previous reviews of the states of São Paulo, Rio Grande do Sul, and Bahia were also incorporated.

This paper presents the results of an observation study of interactions between bicyclists and buses on shared bus lanes. Straight sections of two bus lanes shared with bicyclists in Belgium have been observed, and all interactions between bicyclists and buses during two full weeks have been recorded and analysed. Additionally the lateral position and riding speed of bicyclists that are in interaction with buses is compared with the behaviour of a control group. One of the bus lanes is in line with road design guidelines in a number of countries that state that a sufficiently narrow bus lane (

The aims of this work are to better understand (1) the relation between exposure and the risk of an accident between pedestrians and motorized vehicles and between bicyclists and motorized vehicles occurring at urban intersections and (2) how the speed environment and the victim´s age relate to the injury severity/outcome once a pedestrian or a bicyclist has been struck by a motorized vehicle. Cross sectional studies are used, and the relations are analyzed using multinomial logit models, negative binomial regression and other statistical methods. The results show that there is a positive correlation between the exposure of pedestrians, bicyclists and motorized vehicles and the number of accidents, i.e. the more road users there are, the more accidents occur. The models also suggest that this relation is non-linear; the accident risk per road user is lower at sites where the exposure is greater (safety in numbers effect). Furthermore, the results show safety in numbers effect for single pedestrian accidents, which might suggest that the underlying reasons for this effect is more complex than previously assumed. The thesis suggest an alternative way to interpret risk values and risk curves for injury severity/outcome (if one is involved in an accident), in which differences arise depending on whether the aim is to interpret the relation from an individual perspective or from the perspective of society as a whole. The results furthermore show a strong correlation between the speed environment, the age of the victim and the injury severity/outcome. A considerable proportion of the serious injuries occurs in low speed environments, seniors suffer more serious injuries than younger pedestrians and cyclists do, and the effects differ substantially for struck pedestrians versus struck bicyclists.

The results furthermore show a strong correlation between the speed environment, the age of the victim and the injury severity/outcome. A considerable proportion of the serious injuries occurs in low speed environments, seniors suffer more serious injuries than younger pedestrians and cyclists do, and the effects differ substantially for struck pedestrians versus struck bicyclists. This work is focused on two accident types: accidents between motorized vehicles and pedestrians, and accidents between motorized vehicles and bicyclists. It aims at better understanding how the number of accidents is related to the number of road users; and how the speed at the site and age of the victim is related to how severe the injuries are. The work relies on several different statistical techniques to study those relations. The results show that there is a relation between the number of road users and the numbers of accidents, that is, if there are more road users, there are more accidents. The results further suggest that the risk of an accident per road user is lower at sites where the number of road user is high, compared to sites where the number of road users is low. This effect is also apparent for pedestrian fall accidents (single accidents) which allow us to reflect over the current theories regarding to why the models show this effect. Risk values and risk curves are frequently used when working with traffic safety, where the probability of serious or fatal injuries is presented against some other variable, for example speed. The thesis suggest an alternative way to interpret those risk values and risk curves, where the approach depends on if it is from the perspective of the individual or from the perspective of the society as a whole. The results furthermore show that the speed environment and the age of the victim are closely related to the probability of sustaining serious or fatal injuries. A considerable proportion of the serious injuries occur in low speed environments, seniors suffer more serious injuries than younger pedestrians and cyclists do, and the effects differ substantially for struck pedestrians versus struck bicyclists.

In The Netherlands, on bicycle paths, single-bicycle accidents, bicycle-bicycle and bicycle-moped accidents constitute a considerable share of all bicyclist injuries. Over three quarters of all hospitalised bicyclist victims in the Netherlands cannot be directly related to a crash with motorised traffic. As the usage of bicycle paths steadily increases, it is to be expected that safety on bicycle paths will become a major issue in the coming years in The Netherlands. A study was conducted into the behaviour of bicyclists and moped riders to improve traffic safety on bicycle paths. By behavioural observations with video, mutual conflicts and bicyclist behaviour on bicycle paths were recorded and analysed, among other things by means of the conflict observation method DOCTOR (Dutch Objective Conflict Technique for Operation and Research). The explorative phase of the study (phase 1), included two research locations, one in the city of Amsterdam and one in Eindhoven. The results gave guidance for a better understanding of the behaviour between different users of separate two-directional bicycle paths. An example includes the relationship between bicyclist-moped rider behaviour and the width of the bicycle path. For a condition with busy bicycle traffic in both directions the width of the bicycle path in Amsterdam (effectively 3.55 m) is relatively narrow, whereas the bicycle path width in Eindhoven (>4.94 m) appears to be sufficient to accommodate large flows of bicyclists. Because of a large flow of crossing pedestrians resulting in (severe) conflicts with bicyclists in Amsterdam, additional countermeasures to better control these interactions are needed. The DOCTOR conflict observation method from video appears to be applicable for conflicts between intersecting road users and for head-on conflicts on the bicycle path. Conflict situations between bicyclists in the same direction (constituting an important share of injury accidents on bicycle paths) require an additional and more general systematic observation of specific behaviour. Therefore, phase 2 of the project will focus in particular on interactions between bicycle path users in the same direction and underlying processes. © 2013 Elsevier Ltd.

We conducted individual and ecologic analyses of prospectively collected data from 839 injured bicyclists who collided with motorized vehicles and presented to Bellevue Hospital, an urban Level-1 trauma center in New York City, from December 2008 to August 2014. Variables included demographics, scene information, rider behaviors, bicycle route availability, and whether the collision occurred before the road segment was converted to a bicycle route. We used negative binomial modeling to assess the risk of injury occurrence following bicycle path or lane implementation. We dichotomized U.S. National Trauma Data Bank Injury Severity Scores (ISS) into none/mild (0–8) versus moderate, severe, or critical (>8) and used adjusted multivariable logistic regression to model the association of ISS with collision proximity to sharrows (i.e., bicycle lanes designated for sharing with cars), painted bicycle lanes, or physically protected paths. Negative binomial modeling of monthly counts, while adjusting for pedestrian activity, revealed that physically protected paths were associated with 23% fewer injuries. Painted bicycle lanes reduced injury risk by nearly 90% (IDR 0.09, 95% CI 0.02–0.33). Holding all else equal, compared to no bicycle route, a bicycle injury nearby sharrows was nearly twice as likely to be moderate, severe, or critical (adjusted odds ratio 1.94; 95% confidence interval (CI) 0.91–4.15). Painted bicycle lanes and physically protected paths were 1.52 (95% CI 0.85–2.71) and 1.66 (95% CI 0.85–3.22) times as likely to be associated with more than mild injury respectively.

The Tool for Rapid Assessment of City Energy (TRACE) is used for conducting rapid assessments of energy use in cities. It helps prioritize sectors with significant energy savings potential, and identifies appropriate energy efficiency interventions across six sectors-transport, municipal buildings, water and waste water, public lighting, solid waste, and power and heat. It is a simple, low-cost, user-friendly, and practical tool that can be applied in any socioeconomic setting. This report is based on the implementation of the TRACE tool in Ploiesti in February 2013, and it outlines ideas on what the city could further do to improve its energy efficiency performance. It details the analysis carried out and the recommendations derived as a result, for energy efficiency action plan, district heating maintenance and upgrade, non-motorized transport, public transport development, parking restraint measures, traffic restraint measures, municipal buildings audit and retrofit, and street lighting timing program.

- Abstract
Recent literature indicates that active lighting, when strategically positioned, improves bicyclists' conspicuity at night. Road cyclists are unique among other vulnerable road users in two ways: 1) they can leverage their own biological human motion and mechanical bicycle motion when using conspicuity solutions; 2) their visual surface area shown to approaching traffic is greater when viewed from a right angle (i.e., 90 degrees) than from the front/rear. However, research has not yet identified how to utilize these factors to maximize conspicuity. This project investigated the conspicuity benefits of using various configurations of six LEDs on a cyclist's body and bicycle. Experiment 1 quantified participants' responses to video recordings of a nighttime drive that featured a test bicyclist. Experiment 2, a nighttime study on a closed road, quantified participants' subjective ratings of bicyclist conspicuity at night. The findings from these studies confirmed that capitalizing on drivers' sensitivity to patterns of motion can significantly enhance bicyclists' nighttime conspicuity when viewed from the side. Particularly effective is highlighting the rotating motion of a bicycle's wheels, allowing drivers to quickly and easily identify bicyclists.

This study looked at whether drivers overtaking a bicyclist changed the proximities of their passes in response to the level of experience and skill signalled by the bicyclist's appearance. Five outfits were tested, ranging from a stereotypical sport rider's outfit, portraying high experience and skill, to a vest with ‘novice cyclist’ printed on the back, portraying low experience. A high-visibility bicycling jacket was also used, as were two commercially available safety vests, one featuring a prominent mention of the word ‘police’ and a warning that the rider was video-recording their journey, and one modelled after a police officer's jacket but with a letter changed so it read ‘POLITE’. An ultrasonic distance sensor recorded the space left by vehicles passing the bicyclist on a regular commuting route. 5690 data points fulfilled the criteria for the study and were included in the analyses. The only outfit associated with a significant change in mean passing proximities was the police/video-recording jacket. Contrary to predictions, drivers treated the sports outfit and the ‘novice cyclist’ outfit equivalently, suggesting they do not adjust overtaking proximity as a function of a rider's perceived experience. Notably, whilst some outfits seemed to discourage motorists from passing within 1 metre of the rider, approximately 1-2% of overtakes came within 50 cm no matter what outfit was worn. This suggests there is little riders can do, by altering their appearance, to prevent the very closest overtakes; it is suggested that infrastructural, educational or legal measures are more promising for preventing drivers from passing extremely close to bicyclists.

Quiet vehicles may be noticed relatively late and therefore constitute a potential risk for vulnerable road users such as pedestrians and bicyclists. The ideal acoustic warning signal generator notifies vulnerable road users while minimizing noise pollution. Several sensor systems exist which are able to reveal the position of the vulnerable road users, which information can be used by the warning signal generator. The warning signal generator is designed to generate the specified warning signal at the location of the vulnerable road user while the acoustic response at other locations is minimized. The directional sound beam was realized with an array of controlled actuators, using least-squares beamforming methods. The particular least-squares methods are based on measured transfer functions between the actuators and the acoustic sensors. Different actuator technologies were evaluated. Changes of the relative positions of the vehicle and the vulnerable road user require continuous adjustments of the sound beam. The latency of the beamforming method with respect to an adjusted beaming direction is an important factor for the present application. Different methods to generate the sound beam are described and advantages of the different beamforming methods in experimental results are shown. Rapid real-time adjustment of the beaming direction is demonstrated.

Several studies have shown that a significant amount of daily air pollution exposure, in particular Black Carbon (BC), is inhaled during trips. Assessing this contribution to exposure remains difficult because on the one hand local air pollution maps lack spatio-temporal resolution, at the other hand direct measurement of particulate matter concentration remains expensive. This paper proposes to use in-traffic noise measurements in combination with geographical and meteorological information for predicting BC exposure during commuting trips. Mobile noise measurements are cheaper and easier to perform than mobile air pollution measurements and can easily be used in participatory sensing campaigns. The uniqueness of the proposed model lies in the choice of noise indicators that goes beyond the traditional overall A-weighted noise level used in previous work. Noise and BC exposures are both related to the traffic intensity but also to traffic speed and traffic dynamics. Inspired by theoretical knowledge on the emission of noise and BC, the low frequency engine related noise and the difference between high frequency and low frequency noise that indicates the traffic speed, are introduced in the model. In addition, it is shown that splitting BC in a local and a background component significantly improves the model. The coefficients of the proposed model are extracted from 200 commuter bicycle trips. The predicted average exposure over a single trip correlates with measurements with a Pearson coefficient of 0.78 using only four parameters: the low frequency noise level, wind speed, the difference between high and low frequency noise and a street canyon index expressing local air pollution dispersion properties.

Every year, in Sweden, more than 4,000 people require inpatient care for single injury incidents obtained while walking or bicycling in a traffic environment. The aim of this study is to describe causes of single injury incidents among pedestrians and bicyclists and to identify preventive strategies. The study is based on data from the injury registration database at the University Hospital in Umeå and from a complementary questionnaire containing questions regarding the causes of injury and preventive strategies. The questionnaire was distributed to all pedestrians and bicyclists injured in single incidents in a city in northern Sweden and who had visited the hospital in 2009 because of those injuries. The data set is comprised of medical data for all 367 patients (244 pedestrian and 123 bicyclists) who responded to the questionnaire. The results from this study show that the pedestrians and bicyclists differ in their reports regarding causes of their injuries and the differences seem to be related to injury severity. The pedestrians mainly referred to environmental factors as causes to their injuries, while the bicyclists referred to environmental factors, product factors, and human factors as causes of the injury incident. Regarding preventive strategies, the views of the pedestrians and the bicyclists is in line with their views of causes to their injuries. The results are useful for developing preventive strategies for differing groups of road users.

The introduction of urban rail transit and high performance/quality/capacity bus transit systems throughout the world has dramatically improved the mobility of residents of cities in which they operate. The objectives of this work are: to provide a technical resource for transit planners and designers in developing cities in their public transport capacity and performance analysis work irrespective of mode. This report recommends methods of achieving practical transit capacity during normally encountered operating conditions. Where capacity is influenced by a measure of dispersion of some characteristic such as stop dwell time or vehicle headway, this is also noted. The purpose of measuring capacity is not just to provide a measure of system capability to transport passengers but also to provide some insight into the effect of service and physical design on customer service quality. When the demand for a service exceeds its schedule design capacity, service quality deteriorates either due to overcrowding on vehicles or at station platforms or diminished ability of customers to board the next arriving transport vehicle since it is already fully loaded, increased dwell times and hence decrease revenue speeds. The importance of service quality in transit capacity analysis cannot be overstated. Transit operators should be mindful that the urban transportation marketplace is more competitive. While it might be technically possible to design a service using a loading standard of 7 or 8 passengers per square meter, a number of customers will find that level intolerable and will seek alternate means of travel including walking (in the case of short distance trips), riding with someone else, riding taxis or purchasing a motorcycle or car. Accordingly, such loading standards should be thought of as interim measures until higher capacity at lower crowding can be achieved.

The World Bank Group (WBG) has focused on reducing the environmental impacts of its internal operations and improving corporate environmental practices since 2002, when the WBG President announced WBG's commitment to Corporate Social Responsibility (CSR). The objective of this document is to summarize the actions WBG has taken thus far to reduce environmental impacts from internal operations and present an action plan to further integrate sustainability into WBG's internal operations. Although this work focuses on the environmental impact associated with WBG daily operations, the links between WBG policies and actions related to environmental management and the financial/social considerations are significant. The International Finance Corporation (IFC) footprint and World Bank corporate responsibility teams facilitate the sustainability commitment of the WBG and monitor and track its progress. These teams provide technical information and research support to a dedicated group of champions throughout the WBG who implement emission reduction activities. Budget for these activities flows primarily through the environment department, the general services department, and IFC facilities management and administration. The environment department and IFC facilities management each resource one staff member to provide back-up research support and to monitor and report on environmental metrics, with building engineers and managers and project officers from across the WBG contributing.

- Abstract
The implementation of community injury prevention programs in order to reduce injuries caused by road traffic incidents has been a public health priority for many years. The purpose of this case-study was to investigate whether the implementation of traffic safety countermeasures on a bridge for bicyclists and pedestrians was effective in reducing the number and severity of injuries. The study was based on data from the injury database at the University Hospital of Umeå and includes data from 74 injured persons. Injury incidence, injury severity and the circumstances associated with injury incidences are reported. There was an increase in the incidence of both moderate and more serious injuries, such as brain injuries and fractures of upper extremities, after the safety countermeasures were put in place. Falls due to overturning with the bicycle dominated among single crashes. Collisions and crashes caused by giving way to pedestrians or other bicyclists were the most common types of crash. The main finding is that the modification of the bridge, which aimed to reduce injuries, has not been successful, in particular with reference to the incidence of severe injuries.

Few international studies have so far been conducted in terms of professional drivers' speed compliance in urban areas, and even fewer on professional drivers' compliance with rights of way at pedestrian crossings. The project began with a literature review to identify existing knowledge on the role of professional drivers in traffic. The municipalities of Luleå, Piteå, Kalix and Älvsbyn in Sweden were contacted for information about the project and for cooperation in the selection of study sites. Speed measurements with a handheld laser were conducted in the urban environment with the focus on commercial vehicles such as buses, trucks, freight services, taxis and service vehicles. In parallel with the speed measurements, video recording was conducted for observational studies of yielding behaviour at pedestrian crossings in the urban environment, with the focus on commercial vehicles. Professional drivers as a group are not clearly distinguished from other drivers regarding compliance with speed limits and, when they differed from other drivers, it was in a negative way. Bus drivers and taxi drivers drove faster than other drivers at sites with maximum speed limit of 30 km/h, and the tendency was that taxi drivers also drove faster on roads with maximum speed limit of 50 km/h. Professional drivers are much like other drivers. This averages that it is common that the relevant rules not are followed, two to three out of ten drivers do not give priority to pedestrians at marked pedestrian crossings. This also applies to professional drivers. Godkänd; 2010; 20101216 (chjo)

Tavoitteena oli kehittää kaksi helppokäyttöistä, luotettavaa ja lyhyttä testiä, joiden avulla polkupyöräilijät ja jalankulkijat saavat palautetta käyttäytymisensä vaikutuksista liikenneturvallisuuteen. Lähtökohtina olivat vastaajan itsearviointi, tiedossa olevat käyttäytymisen ja vakavien liikenneonnettomuuksien väliset yhteydet sekä kevyen liikenteen sääntöjen tuntemus. Testin käyttöympäristöksi ajateltiin ensisijaisesti työpaikkoja. Testiä varten laadittiin sekä polkupyöräilijöille että jalankulkijoille oma internetpohjainen kyselylomake, joka kohdistuu erilaisiin käyttäytymistekijöihin. Aiheita olivat mm. turvallisuusvarusteet, reitinvalinta, alkoholin vaikutuksen alaisena liikkuminen, kelin huomioon ottaminen, liikennesääntöjen noudattaminen, vuorovaikutustilanteet autojen kanssa ja keinot turvallisuuden parantamiseksi. Vastausten perusteella vastaaja saa yksilöidyn ja kysymyskohtaisen palautteen siitä, miten hänen kannattaa muuttaa käyttäytymistään parantaakseen turvallisuuttaan liikenteessä. Lisäksi annetaan vastauksiin perustuva kokonaisarvio liikennekäyttäytymisen vaarallisuudesta. Neste Oilin henkilöstö koekäytti testit. Tulosten mukaan teknisiä ongelmia ei ilmaantunut ja käyttäjät pitivät sisältöä onnistuneena.

Nemotorizirani udeleženci v cestnem prometu veljajo za najšibkejše in najbolj ogrožene prometne udeležence, saj niso zaščiteni tako kot vozniki v vozilu. Prav zaradi tega je visok odstotek smrtnih žrtev prometnih nesreč v katerih so udeleženi pešci in kolesarji. Diplomska naloga zajema varnost udeležencev v cestnem prometu tako v Sloveniji kot tudi v Evropski uniji, s poudarkom na prometnih nesrečah v katerih so bili udeleženi pešci in kolesarji na območju Policijske uprave Celje, v obdobju od leta 2003 do leta 2008, ter predlogi in ukrepi za zmanjšanje nesreč in izboljšanje prometne varnosti. Unmotorized participants in the road traffic are the weakest and most vulnerable traffic participants, because they are not protected like the drivers in the vehicles. Because of that it is high percentage of mortally victims in the traffic accidents in which are involved pedestrians and bicyclists. Degree task contains safety of road traffic users in Slovenia and also in European Union, with accentuation on traffic accidents in which were included participate pedestrians and bicyclists in the area of Celje Police Department, in the period since 2003 until 2008, and propositions and measures for reduction accidents and improvement of road safety.

This report provides an overview of the challenges and opportunities in addressing road safety in the Europe and Central Asia (ECA) region. It presents information on the size, characteristics, and causes of the problem; presents evidence on the effectiveness of measures that countries world-wide have adopted to improve road safety; briefly describes current international road safety policy; and discusses a range of strategies and actions that could be undertaken by the World Bank in coordination and partnership with the World Health Organization (WHO), multilateral development banks, other international agencies and donors, as well as with private and civil society institutions. A primary audience of this report is internal-particularly managers and staff of the World Bank working in the transport, health, education, and governance sectors, to raise awareness about the multisectoral nature of the road safety challenge and of effective options to address it. It proposes ways that the World Bank might engage more to support ECA countries in tackling this issue, working in partnership with other international agencies and donors. The secondary audience is external policymakers, senior analysts, program managers, and their advisers in the governments of ECA countries, private sector officials, and civil society and international organizations working in this field. The goal is to support discussion on appropriate choices and instruments for advancing the road safety agenda as a top development priority over the short and medium term.

- Abstract
Bicycling at night is more dangerous than in the daytime and poor conspicuity is likely to be a contributing factor. The use of reflective markings on a pedestrian’s major joints to facilitate the perception of biological motion has been shown to greatly enhance pedestrian conspicuity at night, but few corresponding data exist for bicyclists. Twelve younger and twelve older participants drove around a closed-road circuit at night and indicated when they first saw a bicyclist who wore black clothing either alone, or together with a reflective bicycling vest, or a vest plus ankle and knee reflectors. The bicyclist pedaled in place on a bicycle that had either a static or flashing light, or no light on the handlebars. Bicyclist clothing significantly affected conspicuity; drivers responded to bicyclists wearing the vest plus ankle and knee reflectors at significantly longer distances than when the bicyclist wore the vest alone or black clothing without a vest. Older drivers responded to bicyclists less often and at shorter distances than younger drivers. The presence of a bicycle light, whether static or flashing, did not enhance the conspicuity of the bicyclist; this may result in bicyclists who use a bicycle light being overconfident of their own conspicuity at night. The implications of our findings are that ankle and knee markings are a simple and very effective approach for enhancing bicyclist conspicuity at night.

- Abstract
Despite the importance of multi-use trails in urban non-motorized transportation networks, transportation planners, engineers, and trail managers lack tools for describing economic activity associated with local trail use and for predicting bicycle and pedestrian demand for trails. New tools are needed to plan and prioritize investments in new facilities and to inform management and maintenance of trail infrastructure. Among other needs, they need tools to predict (1) expenditures by local users to support local economic development initiatives and assess neighborhood effects of proposals for trail development and (2) trail traffic demand for optimizing investments and managing maintenance of systems and facilities. This thesis responds to these needs and augments the burgeoning literature on trail traffic analysis by developing models of trail-related expenditures and mode-specific trail demand models. From the expenditures by local users side, using the results of intercept surveys completed by 1,282 trail users on the Central Ohio Greenway trail network in 2014, this thesis estimates the probabilities and patterns that different types of trail users will make expenditures. Approximately one-fifth of trail users reported spending between US$15 and US$20 for food, drink, and other incidental items. Across all trail users the average expenditure by individuals is about US$3 per visit. All else equal, cyclists are more than twice as likely than other users to report expenditures. Users visiting trails principally for recreation are 53% more likely to spend, while users visiting trails mainly for exercise were about 19% less likely. Both longer trips to and on the trails are associated with higher spending. From the trail traffic demand side, this thesis employs trail traffic volumes recorded at 15-minute intervals for 32 multi-use trails located in 13 urban areas across the United States from January 1, 2014 through February 16, 2016. The results of analyses indicate (1) daily trail traffic varies substantially – over three orders of magnitude – across the monitoring stations included in the study; (2) daily trail traffic is highly correlated with weather, and the parabola form of weather parameters works well for modeling variables such as temperature, where trail use is associated with warmer temperatures, but only up to a point at which higher temperatures then decrease use; (3) bicyclists and pedestrians respond differently to variations in weather, and their responses vary both within and across regions; (4) with only a few exceptions, average daily pedestrians (ADP) and average daily bicyclists (ADB) are correlated with different variables, and the magnitude of effects of variables that are the same varies significantly between the two modes; (5) the mean relative percentage error (MRPE) for bicyclist, pedestrian, and mixed-mode demand models, respectively, are 65.4%, 85.3%, and 45.9%; (6) although using multimodal monitoring networks enables us to juxtapose the bicyclist demand with pedestrian demand, there is not a significant improvement in predicting total demand using multimodal sensors; (7) a new post-validation procedure improves the demand models, reducing the MRPE of bicyclist, pedestrian, and mixed-mode models by 27.2%, 32.1%, and 14.1%. Transportation planners, engineers, and trail managers can use these results to estimate the effects of weather and climate on trail traffic and to plan and manage facilities more effectively. The developed models also can be used in practical applications such as selection of route corridors and prioritization of investments where order-of-magnitude estimates suffice.

- Abstract
A key challenge for the developing perception-action system is learning how to move the self in relation to other moving objects. This often involves perceiving and acting on affordances or possibilities for action that depend on the relation between the characteristics of the individual and the properties of the environment (Gibson, 1979). This chapter overviews our program of research on perceiving and acting on dynamic affordances (i.e., possibilities for action that vary over time). Our goal is to bridge the divide between basic and applied research by using road crossing as a model system for studying how children's ability to perceive and act on dynamic affordances undergoes change with age and experience. The basic task is for participants to cross virtual roads with continuous traffic either on foot or on a bicycle. This work reveals that children's gap choices and crossing motions are less tightly linked than those of adults. Children often choose the same size gaps as adults but time their entry into those gaps less tightly than adults. As a result, children typically end up with less time to spare than adults when they clear the path of the vehicles. Improvement in gap selection and movement timing occurs gradually over development, indicating the perception-action system undergoes continuous change well into adolescence. As in other areas of development (e.g., face perception, word recognition), this kind of gradual developmental change appears critical for the fine-tuning of the system. The late development of these skills may explain also why adolescent pedestrians, cyclists, and drivers continue to be at risk for collisions when crossing roads. Further work aimed at better understanding the developmental mechanisms underlying these changes will inform the fields of both developmental science and injury prevention., (Copyright © 2018 Elsevier Inc.

- Abstract
Indian cities face a transport crisis characterized by levels of congestion, noise, pollution, traffic fatalities and injuries, and inequity far exceeding those in most European and North American cities. India's transport crisis has been exacerbated by the extremely rapid growth of India's largest cities in a context of low incomes, limited and outdated transport infrastructure, rampant suburban sprawl, sharply rising motor vehicle ownership and use, deteriorating bus services, a wide range of motorized and non-motorized transport modes sharing roadways, and inadequate as well as uncoordinated land use and transport planning. This article summarizes key trends in India's transport system and travel behavior, analyzes the extent and causes of the most severe problems, and recommends nine policy improvements that would help mitigate India's urban transport crisis.

- Abstract
Background: Transport statistics classify bicyclists in a separate road user collective. For medical reasons, this differentiation is applied as well. Much literature is published in this field. Nevertheless there is a lack of literature regarding the overall injury patterns in a defined injury severity collective. Most literature is about isolated injured regions in combination with a heterogeneous injury severity. Further parameters, such as injury patterns, epidemiological aspects, treatment focal points and characteristic outcomes, have also been studied. The aim of the present study was to evaluate and characterize injury patterns in a standardized and representative collective of severely injured bicyclists. Methods We analysed data from the Traumaregister DGU® from 2002 to 2010. In total, 2817 severely injured (ISS ≥ 9 and additional intensive/intermediate care unit) bicyclists were included. The primary endpoint was evaluation of injury patterns and injury focal points. In addition to that we analysed parameters like epidemiological aspects, circumstances of accident, treatment focal points and outcome., Results: The mean age was 50.3 ± 20.9 years. Males accounted for 68.9 % (n = 1940). The mean ISS was 23.7 ± 12.6. The mean AIS regions were the head 71.9 % (n = 2025), the chest with 44.9 % (n = 1264) and the upper extremities 33.6 % (947). In 68.2 % of all cases an ISS ≥ 9 was achieved by a traumatic brain injury; 21.1 % of all cases were mono-injuries. A characteristic distribution of age and a characteristic prevalence of the accidents in relation to the weekday and the month could be shown., Conclusion: The present study analysed the largest ever published collective of severely injured bicyclists. Traumatic brain injury could clearly be shown as the main injury in this collective. Moreover, one of five cases achieved the state "severely injured" due to mono-injury.

- Abstract
We conducted individual and ecologic analyses of prospectively collected data from 839 injured bicyclists who collided with motorized vehicles and presented to Bellevue Hospital, an urban Level-1 trauma center in New York City, from December 2008 to August 2014. Variables included demographics, scene information, rider behaviors, bicycle route availability, and whether the collision occurred before the road segment was converted to a bicycle route. We used negative binomial modeling to assess the risk of injury occurrence following bicycle path or lane implementation. We dichotomized U.S. National Trauma Data Bank Injury Severity Scores (ISS) into none/mild (0-8) versus moderate, severe, or critical (>8) and used adjusted multivariable logistic regression to model the association of ISS with collision proximity to sharrows (i.e., bicycle lanes designated for sharing with cars), painted bicycle lanes, or physically protected paths. Negative binomial modeling of monthly counts, while adjusting for pedestrian activity, revealed that physically protected paths were associated with 23% fewer injuries. Painted bicycle lanes reduced injury risk by nearly 90% (IDR 0.09, 95% CI 0.02-0.33). Holding all else equal, compared to no bicycle route, a bicycle injury nearby sharrows was nearly twice as likely to be moderate, severe, or critical (adjusted odds ratio 1.94; 95% confidence interval (CI) 0.91-4.15). Painted bicycle lanes and physically protected paths were 1.52 (95% CI 0.85-2.71) and 1.66 (95% CI 0.85-3.22) times as likely to be associated with more than mild injury respectively., Competing Interests: Conflicts of Interest: The authors declare no conflict of interest.

- Abstract
Because many bike facilities in America must be fit within constrained roadway right-of-way, bicyclists will continue to have to interact with motorists, and the details of these cyclist/motorist interactions are crucial to the understanding of bicycle and motorist comfort and safety. Previous studies have analyzed these interactions along roadways without road-side parking; however, the presence of parked cars has many possible implications on motorist and cyclist behavior. This study hopes to help fill this gap in knowledge by studying the effects of different parking arrangements on these behaviors. Cyclists were hired to ride laps along sites with bike lanes and roadside parking, and the positions of both cyclists and passing motorists were captured on video. The data indicates that cyclists pay attention to the type of parked vehicles they are passing; vehicles parked close to the bike lane tend to pose a threat to cyclists, who then pass closer to the motor vehicle lane. When vehicles are parked farther away, cyclists have more of a safety buffer and therefore tend to move away from the motor vehicle lane. Passing motorists generally do not pay attention to details of parking, probably because they have a sufficient buffer because of the bike lane. However, when they are passing a cyclist, motorists do tend to provide the cyclist with more room if vehicles are parked close to the bike lane.

- Abstract
Ray Rusher achieved popularity in the late 1970s as an avid bicyclist who was a familiar sight on Arlington Heights streets. Rusher, who was born in Iowa in 1902, took up biking in 1977 at age 76 to fight depression after the death of his wife, Irene. He pedaled an average of 25 miles a day, eventually logging more than 34,000 miles. He belonged to the Arlington Heights Bicycle Association, the League of American Wheelmen and served with the Arlington Heights Park District’s Friends of the Parks program. His cycling days ended when a bicycle accident left him with a broken leg and hip in 1981. He died in Springfield, Missouri, in 1983 at the age of 80. This item is part of the collection of the Arlington Heights Historical Society (http://www.ahmuseum.org).

- Abstract
The high-wheel was the first bicycle to catch on in Indiana. With a very large front wheel and small back wheel, this bicycle took quite a bit of skill to ride. Because of the skill required to master it, the high-wheel was a bicycle for enthusiasts and produced wheelman's clubs and competitions. This group is identified as the Zig Zag Club. Once the safety bicycle with two wheels the same size was invented, the high-wheel became known as the "Ordinary."
