Abstract : The objective of this work is the realization of a system allowing to assist the travellers, and to facilitate their movement in normal and degraded functioning of the transport network. This system aims to minimize the waiting time of the travellers, in degraded mode, at exchanges stations and to assure them, as well as possible, the continuity of their journey in the multimodal transport networks. So it improves the quality of the service returned to the travellers in order to inform them. A first part of the work in this thesis concerns conception, development and validation of our approach which allows giving optimal or almost optimal solutions for a normal and disrupted transport system. This approach uses a multi-objective method of search for optimal route which leans on a hybridization between a modified Dijkstra algorithm and a genetic algorithm. The modified Dijkstra algorithm gives us a set as solutions serving of initial population for the genetic algorithm.
The modelling of the transport system is represented by multi-zones architecture. This architecture shows us the distributed aspect of the system, and the interactions and the relations which can take place among various zones. We present in this work a Multi-agent system of Help to the Movement. These agents use the module of optimization developed in the first part. Our work is realized within the framework of the "VIATIC-MOBILITE" project, which is the project 6 of the I-Trans Competitiveness cluster.
