Coupled Map Lattice Model based on Driving Strategy for City Traffic Simulation

摘要: In city traffic flow, vehicles driven by human interact with each other velocity fluctuations. We simulate the such and analyze it. It should be important to research relation between signals drivers’ strategies. Then, we prepare two CML(coupled map lattice) models treat complex system varying their characteristics, effects of signals. Each model has different strategies avoid collision vehicles. The one is “Mixture Model” strategy which changes vehicles’ running dynamics when gaps have gotten narrow, “Tracking decelerate goal velocities follow previous narrow. compare these CML on a oneway lane under aperiodic boundary condition. “The transition point jam” separates “free flow phase” “congestion observed. free phase, major differences are not confirmed models. But, it gets congested, takes dissimilar features stem from difference Additionally, effect signal control parameters in phase. observed that whole performance improved as cycle length getting shorter, at time offset can’t very effective. When long, lower if proper.
