THE EFFECT OF THE HETEROGENEITY ON THE TRAFFIC FLOW BEHAVIOR

摘要: We propose a traffic flow model which takes into account the disorder in length and maximal speed of cars. Using cellular automaton parallel dynamics we have studied behavior flow, especially condition formation (active phase) dissociation (absorbing platoons. It is found that transition from active to absorbing phase depend on slow vehicles L2. Indeed, discontinuous for L2 = 1 continuous when > 1. In later case, critical exponent calculated near density, space-time diagram shows presence two phases. Furthermore, fundamental exhibit plateau size system.
