摘要:

采用元胞自动机模型研究了城市交通中车辆的换道行为。在模拟非对称换道规则下混合交通流中的车辆换道行为中,通过增加公交车影响因子这一换道动机,分析了公交车对社会车辆换道行为的影响。分析结果表明:公交车的存在增加了车流中车辆的换道概率,且当道路处于中低密度状态时,社会车辆换道概率随公交车比例上升而增加,相应路段平均车速降低。在考虑了公交车影响因子后发现,公交车影响因子的存在会明显降低车辆换道概率。

Abstract:

This article studies the lane-changing behavior of vehicles in urban traffic using cellular automata model. In the simulation of lane-changing behavior in mixed traffic flow under asymmetric lane-changing rules, the impact of buses on the lane-changing behavior of social vehicles is analyzed by adding transit influencing factors as term of motivation. Results show that the presence of buses increases the lane-changing probability of social vehicles. Under the condition of low traffic density, the lane-changing probability of social vehicles with the bus ratio, and at the same time the average speed drops in corresponding road sections. In addition, when considering the bus influencing factors, the lane-changing probability obviously decreases.

Key words: engineering of communications and transportation system, lane changing behavior, mixed traffic flow, bus influencing factor, cellular automata
