A Decision Support Tool to Enlighten Collective Transport Projects Implementations

Users and public authority decision makers are rarely aware of the real costs of travel on public transport. This lack of transparency has a negative effect and slows down the investment decision making process: it relates not only to the economic cost, but the social and environmental costs as well. The initial objective of this work is to develop a tool to evaluate the global costs of the final kilometre of travel in a mountain environment, including different modes of transport such as cable-car, shuttle buses. The second objective is to use this tool in a project to prioritise public transport traffic on a motorway in Marseille. The tool is made up of three modules: 1) An economic analysis to separate the costs by actor (private and public) and by mode of transport; 2) An environmental analysis concerning emissions: nitrogen oxides-NOx, greenhouse gases, and particulates; and 3) A qualitative analysis to appreciate the strengths and weaknesses of the project based on around forty indicators. The use of this tool helped to clarify the public authority's decision to develop the project (2014) to reserve one lane on a motorway in Marseille for public transport and taxis. This paper presents the potentialities and prospects provided by such a decision making tool.
