摘要
考虑到车辆的驾驶员具有其不同的驾驶特点,可以将他们分为谨慎型驾驶员和激进型驾驶员两类。分析他们的相同点和不同点后,建立了单车道元胞自动机混合交通流模型。通过计算机模拟,研究了混合比例与平均速度的关系,随机减速概率对平均速度及流量的影响。结果表明,谨慎型驾驶员的驾驶特点导致谨慎型车辆对道路上车辆平均速度和流量都有不小的负面影响,尤其是道路上车流密度较小的时候。
In this paper, focus on the effect of traffic - flow with different driving behaviors. Two kinds of drivers - aggressive driver and careful driver are oonsidered. Construct a cellular automaton model for traffic - flow on a single- lane roadway to simulate those two kinds of drivers. By using numerical simulations, study the relationship of mixed proportion and average speed, the influence on average speed and flowrate affected by careful driver＇s random deceleration probability. The numerical results show careful driver＇s vehicle can make bad influence on average speed and flowrate of the traffic - flow, especially when the traffic density is very low.
