Le choix du tracé d'une ligne de transport en commun en site propre et de la position de sa plateforme en milieu urbain : l'utilisation des outils mathématiques au service de la concertation

Abstract : Taking into account the environmental aspects and the nuisances due to the massive use of private cars use has an influence on the French agglomerations mobility policies. More and more, these agglomerations develop their own public transport network; the idea is to make public transport more attractive for the users than today and therefore more competitive than private cars. For all cities, the question of the public transport lines implementation is posed at two levels: that of the city to determinate the public transport layout and that of the street in order to choose the position of the transport platform and the distribution of users in the public space. Public transport projects arouse the interest from the local population, and a lot of stakeholders are thus encouraged to participate in them. The multiplicity of stakeholders concerned by the project, and especially the different points of view they defend, can also block the project progress, even leading to its end. Our research is aimed to develop a process to determine, on the one hand, the public transport line layout and on the other, the platform implementation and the public space users distribution. This process has to take into account the aspects linked to transport, those connected to the agglomeration urban design and the different stakeholders' points of view. The methodology we have created is based on the use of ELECTRE III, a multicriteria decision aiding tool, as a support for "concertation"¹. From the historical analysis of the French public transport projects, the criteria used to choose the line layout and the public space users distribution have been determined. Then, the use of ELECTRE III is a support for the debates with the various stakeholders, to highlight the parts of the projects that are problematic because the different viewpoints are divergent. To conduct the debates, a new actor, the facilitator, is introduced in the transport project. From the recommendations stemmed from the concertation stage, the elected representatives, the real project decision makers, can take the necessary steps, notably in terms of communication, so that the project suffers from as fewer delays as possible and attains the acceptance of most stakeholders ¹ The French word "concertation" does not have any real equivalent in English. It designates a participative decision-making process in which the various stakeholders are able to express their point of view and have it taken into account in the decision-making process
