A GLOBAL MODEL FOR THE EVALUATION OF EXTENSION PROJECTS FOR PUBLIC TRANSPORT IN THE PARIS REGIONAL NETWORK

UN MODELE GLOBAL POUR L'EVALUATION DES PROJECTS D'EXTENSION DES RESEAUX DE TRANSPORT PUBLIC EN REGION PARISIENNE

In order to dispose of tools which could cope with the evaluation of a specific project and with the comparison of several transport policies, the RATP has at its disposal a global model for traffic forecasts which is applicable to the whole Paris regional network and which operates in two stages: 1- the estimate of demand (generation and distribution) broken down into 302 independant zones for each socio-professional category comprising - the definition of basic planning data (active residents and employment by zone and by socio-professional category) using an original typological approach, - the generation of intra-zonal flows based upon average levels of service and accessibility, upon the type of zone and its area, - the distribution of inter-zonal flows using a normative model with probability justification. 2- the estimate of traffic (modal split and assignment) broken down by modal category into 600 zones and comprising: - assignment for each network of the "shortest" trips by reference to generalised cost, - modal split using assignment curves with variables based on the relative difference of generalised costs. The outputs of this model are exploited as the basis for comparative studies using the economics of multi-criteria analytical methods. These studies concern the development plan of the RATP, the preparation of the five year regional plan, and the interconnection of the RATP and SNCF rail networks. /TRRL/
