Abstract:
Poster Session. The modeling of pedestrian and vehicle dynamics is of great theoretical and practical interest. In the past two decades research from a broad range of fields such as computer graphics, physics, robotics, social science, safety science and training systems has created simulations involving collections of individuals. Two major kinds of simulations may usually be distinguished depending on whether they seek to achieve: a high- level of behavior realism (safety simulation, social sciences) or high- quality visualization (movie productions, computer games, virtual reality). Within the first category, simulation results are usually consistent with observations of real crowds and can therefore serve as a basis for theoretical studies for the evaluation and prediction of real system behaviors. In the second area, behaviors models are not the priority and do not usually match quantitatively the real world. However, pedestrians and the vehicles are fully animated 3D characters and application users may have a high degree of interaction with the simulation. Recent research and applications tend to unify these two areas, especially in the domain of training systems where both aspects are necessary for an effective training. Our approach is part of this effort, designed for small or large groups of pedestrian and vehicles that may have distinct characteristics and personal goals. Real-time simulation is rather difficult because as soon as we consider a micro- simulation of several individuals and their relationships, the complexity of the system and associated computational costs increase. This directly impact the capabilities of the system to maintain real- time constraint. This poster presents an agent- based pedestrian/vehicle model for real- time interactive simulation. Our approach combines within an integrated model local collision avoidance and global path determination. Additional, the poster will present the different components of the model that are required to simulate such a complex system (environment model...) .
