信号灯随机更新的城市交通网络模型
Signal Controlled Urban Traffic Network Model with Random Update Rule
摘要
Abstract
Objective]An improved two-dimensional cellular automaton model (BML model) was proposed to better simulate real urban traffic network.[Methods]Aiming at the urban traf-fic congestion problem and using the cellular automata method,a traffic signal model with ran-dom update rule was established to study the urban traffic network.[Results]Simulation results showed that the synchronization of the traffic signal has great influence on the traffic system, and the introduction of random update rule significantly reduces the critical density of phase transition.[Conclusion]When the roads are crowed by cars,simultaneous adj usting of signal ar-rangements and periods provides a possible way for relaxing the traffic congestion.关键词
