基于元胞自动机的双车道变道交通流特性研究

在庞杂的城市交通环境下,驾驶员为了寻求更快的速度,常常采用主动的换道行为。由于汽车使用量逐年增长,换道引起的交通事故经常发生。研究车辆变道行为,寻求有效措施减少交通事故的发生,对提高道路安全性具有积极的意义。本文以多车道系统中车辆变道行为为研究对象,以元胞自动机理论为基础,对比分析单向单车道、单向双车道换道行为,并运用MATLAB仿真软件进行分析,获得变道交通流的相关特性曲线。

Research on Traffic Flow Characteristic of Two-lane Systems Based on Cellular Automata

In the complex urban traffic environment,drivers often take the initiative to change lanes in order to seek faster speed. As the use of automobiles increases year by year,traffic accidents caused by lane change often occur. It is of positive significance for improving road safety to study vehicle lane-changing behavior and seek effective measures to reduce the occurrence of traffic accidents. In this paper,vehicle lane-changing behavior in multi-lane system is studied.Based on the theory of cellular automata.The lane-changing behavior of one-way one-lane and one-way two-lane is compared and analyzed by using MATLAB simulation software,and the relevant characteristic curves of lane-changing traffic flow are obtained.
