MODELING AND SIMULATION OF MULTILANE TRAFFIC FLOW

A most important aspect in the field of traffic modeling is the simula tion of bottleneck situations. For their realistic description a macro scopic multilane model for unidirectional freeways including accelerat ion, deceleration, velocity fluctuations, overtaking, and lane-changin g maneuvers is systematically deduced from a gas-kinetic (Boltzmann-li ke) approach. The resulting equations contain corrections with respect to previous models. For efficient computer simulations, a reduced mod el delineating the coarse-grained temporal behavior is derived and app lied to bottleneck situations.
