An evolutionary approach of pedestrians/cars interactions — •arnaud banos1, Abhimanyu Godara2, and Sylvain Lassarre3 — 1arnaud.banos@univ-pau.fr — 2abhimanyu_godara@rediffmail.com — 3lassarre@inrets.fr
Despite the central and fundamental role pedestrian walking plays within the urban transport system, it still remains a badly known transportation mode. The SAMU prototype has been precisely designed to explore the behaviour of pedestrians in interaction with the motorized traffic, in a virtual city where most of the phenomenon can be mastered and studied. Developed in Netlogo, SAMU integrates both cellular Automata and Agent-Based Modelling approaches to generate a new model of cars behaviours by appropriately modifying earlier NaSch-ChSch rules (Nagel and Schreckenberg, 1992) to take into account pedestrian and also turning movements. While being a work in progress, SAMU already provides an ergonomic platform useful to test the behaviour of the system under different configurations of parameters. Anyway, the number of parameters* combinations is so huge that it doesn’t make sense to test them in a very systematic way. Therefore, we propose to explore the possibilities of adding an evolutionary component to our model, based on genetic algorithms, allowing agents (and mainly pedestrians) adapting to given traffic conditions, and finding by themselves the best combinations of their internal parameters that would increase their chance of survival.
