Cet article presente un modele visant a mesurer l'impact de l'accessibilite dans un systeme de transport. Le modele propose integre deux elements majeurs: le prix des biens et le cout de transport. L'impact de ces deux variables a ete explore sous diverses directions: variation d'accessibilite,...

This paper presents new models and methodologies for the assessment of innovative urban transport systems and policies options. The dynamic traffic model METROPOLIS (used here in the framework of the EC project AIUTO) estimates the impact of a set of transport demand management measures on the...

In this paper, we present the results of an extended traveler behaviour survey conducted in Geneva (Switzerland) in March 1994. In this survey, commuters were asked about the impact of various factors, related to individual or household characteristics and situational, contextual and...

We first introduce in this paper the basic bottleneck model with one origin, one destination and one link. There exists an equilibrium for the time of usage. Then we introduce several day-to-day adjustment processes and discuss convergence. Convergence depends on key parameters. In particular we...

This paper presents recent developments of the dynamic traffic simulation model METROPOLIS. This tool is based primarily on the modeling and analysis of information learning and processing by road users. This simulation tool depicts the morning peak commute in large urban areas. Route choice and...

This paper extends research in dynamic traffic modeling using METROPOLIS, a dynamic simulation tool. We briefly present an overview of the original departure time choice model introduces by W. Vickrey (1969) for a single O-D pair. Using this framework for our analysis, we explore how the...

L'objectif de cette etude est d'analyser les accidents routiers des vehicules commerciaux motorises (entreprises de transport par camions et par autobus). Nous voulons particulierement verifier comment les activites de prevention routiere des proprietaires et des conducteurs affectent les taux...

METROPOLIS proposes an interactive environment which simulates automobile traffic in large urban areas. The core of the system is a dynamic simulator ehich integrates commuters' departure time and route choice behavirs over large networks: Drivers are assumed to minimize a generalized travel...

Nous proposons dans cet article un environnement informatique pour decrire le mouvement des pendulaires. cet outil possede trois ingredients essentiels, un simulateur, un interface graphique et un gestionnaire des entrees et des sorties.
