International audience; This paper aims to present a modeling of bike sharing demand at station level in the city of Lyon. Robust linear regression models were used in order to predict the flows of each station. The data used in this project consists of over 6 million bike sharing trips recorded in 2011. The built environment variables used in the model are determined in a buffer zone of 300 meters around each bike sharing station. In order to estimate the bike sharing flow, we use the method of linear regression during the peak periods of a weekday. The results show that bike sharing is principally used for commuting purposes by long term subscribers while short term subscriber's trips purposes are more varied. The combination between bike sharing and train seems to be an important inter-modality. An interesting finding is that student is an important user of bike sharing. We found that there were different types of bikesharing usage which are influenced by socio-economic factors depending on the period within the day and type of subscribers. The present findings could be useful for others cities which want to adopt a bikesharing system and also for a better planning and operation of existing systems. Further, the solutions to encourage the use of bikesharing will be various depending on type of subscribers. The approach in this paper can be useful for estimating car-sharing demand.

International audience; The financial crisis has put pressure on government budgets across Europe. The expectation is that this also has affected public transport budgets in metropolitan areas. This article looks at five cases of metropolitan public transport to see to what extent this is the case. Multi-level governance and fiscal federalism explain the rather surprising outcome.This article is aimed to be a first step into a better understanding of the effect of governance in public transport in a broad sense. It develops the understanding of how the organizational context influences those funding decisions and the related outcome in terms of public transport services provided and passengers transported.The article shows that the effect of budget pressure was varied over the five cases depending on governance in those cases and overall can be characterized as limited. Funding and supply generally kept growing, despite the pressure put on budgets by the financial crisis.

International audience; Urban public transport is currently facing increasing difficulties to obtain funding. While the priority is given to sustainable mobility in cities, the development of the supply leads to increasing operating costs, but the receipts from customers is insufficient to cover the expenses. Taking the example of French cities, the article analyses the reasons of the explosion of deficits. As the design of the network is in France under the full responsibility of Transport Authorities, the growth of the supply is often driven by public policy objectives (accessibility to the city for disadvantaged people, reducing car use and CO2 emissions) rather than by the demand. Even if the patronage starts again increasing since 2000, the global performance of the network is not satisfying, as evidenced by the rather weak rate of utilisation (on average 4 trips per vehicule.km). Apart from the successful development of right-of-way systems (such as tramways), the extension of bus routes to lower density areas explains this mitigated result. It is suggested to develop a line-based performance measurement in order to favour an optimisation now essential to cope with public funding restrictions. Impact indicators are proposed and illustrated on the city of Montpellier.

Urban goods movement and urban logistics started to be defined as a scientific discipline 20 years ago, where several actions in research, development, policy and deployment were started to be coordinated. However, most of the innovations and projects presented in that field are stopped or reduced because of a common constraint that becomes its worst enemy: the financing mechanisms. Although many studies deal with urban logistics, only a few of them show the difficulties at financing, but without entering in detail on the financing mechanisms. This chapter aims to present the main financing issues in urban logistics. First, the main categories of funding strategies that can be applied to urban logistics are presented, focusing on public-private interactions and collaborations. After that, a scenario assessment using a cost benefit analysis framework shows the different interests and issues of each category of stakeholders, and the main advantages and limits of each category of investment and financing strategies. Then, the fields of urban logistics that seem the most adapted to public-private collaboration in terms of financing are identified and commented. As a conclusion, guidelines for researchers and practitioners to take into account financing issues in urban logistics decision support are proposed.

International audience; The “Stated Adaptation” survey is an interactive technique which allows us to obtain a clearer picture of the attitudes and behaviours of individuals when confronted with hypothetical situations, in particular inexperienced travel conditions. This method makes use of a simulation game whose purpose is to explore on small samples individuals' choice processes when selecting between the different transport alternatives which are available to them. This paper describes how gaming-simulation is designed, with reference to the issues tackled by two surveys which have recently been carried out in France (reactions to urban road pricing and perception of electric vehicles). It describes the benefits of this experimental approach which allows stated behaviours to be checked to a considerable degree. The limits and potential developments of this survey technique are also discussed.
