Abstract EN:
The automobile congestion has become the main obstacle for the well functioning of towns. The questions to which we have tried to answer in this study are the following: how can one study the traffic of a city ? which approaches should be used to find solutions ? on what should one focus ? which proceedings are to be chosen ? to study the transportation problems of a typical town like luxembourg, a simulation system, called siloda (operational localised information system dedicated to an accessibility study), has been built; it is based on the concept of accessibility linked to traffic flows to apprehend the aspects of the intra-urban traffic with a set of methods and technics allowing the measure, the analysis and the representation of the multimodal transports including their functional dimension. This system has revealed itself capable of simulating spatially, globally and locally, the multimodal traffic of luxembourg and has permitted to acquaint such a level of knowledge of the big transportation problems of this town, so that it has been possible to make concrete and founded propositions aiming to a better complementarity of the intra, urban transport modes, to remedy to these problems. Therefore, it constitutes a first non negligible and mostly operational step in the relating of components leading to apprehend the intra-urban traffic in terms of accessibility and secondarily flows, on the way to the construction of a real g. I. S. Of this traffic in order to go still further in the analysis and research with more easiness.

La congestion automobile est devenue un principal obstacle au bon fonctionnement des villes actuelles. Ce travail cherche a fournir des reponses aux questions relatives a ce probleme, telles que : comment etudier la circulation d'une ville, quelles approches utiliser pour trouver des solutions ? sur quoi mettre l'accent ? quelle demarche choisir ? pour etudier les problemes de transports d'une ville type comme luxembourg, un systeme de simulation, appele siloda (systeme operationnel d'informations localisees dedie a une etude de l'accessibilite), a ete construit ; il se fonde sur le concept d'accessibilite liee aux flux du trafic pour apprehender les aspects de la circulation intra-urbaine grace a un ensemble de methodes et de techniques permettant la mesure, l'analyse et la representation des transports plurimodaux en incluant leur dimension fonctionnelle. Ce systeme s'est avere capable de simuler spatialement, globalement et localement, la circulation plurimodale de luxembourg et a permis d'acquerir un niveau de connaissances des grands problemes de transports de cette ville tel qu'il a ete possible de faire des propositions concretes et fondees, visant une meilleure complementarite des modes de transports intra-urbains, pour y remedier. Il constitue de ce fait un premier pas, non negligeable et surtout operationnel, dans la mise en relation de composantes conduisant a apprehender la circulation intra-urbaine plurimodale en termes d'accessibilite et secondairement de flux, sur le chemin de la construction d'un veritable s. I. G. De cette circulation afin d'aller encore plus loin dans les analyses et les recherches, avec plus de facilites.
