From Perception to Conflict Resolution: A Priority Managing Mechanism for Road Intersections

Traffic jams constitute an important problem in the cities. Before improving or modifying the infrastructure and the traffic equipments, it seems necessary to evaluate and to measure their impacts on the traffic system on the capacity as well as on the safety. The evaluation of the proposed solutions can be done by tools such as microscopic traffic simulation models, provided that the studied solution deals with local phenomena. But to study the local traffic situations it would seem necessary to take into account the driver's behaviors. Nevertheless, in many traffic studies, the authors introduce normative behaviors in their models, e.g. they follow the rules from the highway code. Unfortunately, the drivers behaviors are not normative, moreover in some crossroad situations they can established their informal rules which can differ from the established ones. Not to take into account the driver's behavior in the crossroad modeling is a barrier for a better use of the traffic simulation models. Our aim in this paper is to present a model where the driver's behavior is based on a larger view of its environment, and thus to propose a new mechanism focused on both the resolution of the conflicts at the crossroad and the management of the longitudinal space, e.g. the space in the front of the simulated driver. This mechanism allows the storage at the center of the intersection independently of the equipment.
