| 摘 要： | 结合元胞自动机的理论,对车辆运行建立了交通流数学模型.通过C++软件描述了运行车辆除超车之外靠右行规则下,交通流量随换道概率变化的情况;通过Matlab软件进行仿真模拟,揭示了交通密度在右行规则控制下所形成的交通流的规律性.结果表明:在靠右行驶规则下,适当的转向概率和车速有利于交通流量的提升.

| Abstract: | Based on the theory of cellular automata （CA）, a mathematical model of traffic flow was established. By using C ＋ ＋ software,changes of traffic flow with lane changing probabilities for running vehicles under the rule of Keep-Right-Except-To-Pass was given. Through the simulation of Matlab,the regularity of traffic flow in the Keep-Right-Except-To-Pass control was revealed. The study shows that under the rule,an appropriate turning probability and speed can benefit the traffic flow. |
