Abstract:

为更好地分析交通流运行规律,实现有效的交通控制和优化,提出结合改进跟驰模型的交通流元胞自动机(cellularAutomata,CA)仿真模型。首先在分析正比于速度的间距倒数模型和Bierley模型特点的基础上,改进得到更符合实际的跟驰模型,进而创建的CA模型结合改进跟驰模型计算并离散化得到的加速度,进行车辆及整条车道的状态更新。通过模型仿真,得到速度差灵敏度系数λ、车辆间距灵敏度系数k和安全距离参数α不同取值时的交通流基本图和X-t时空状态图。通过仿真发现,λ,k的取值很大程度影响图形形状,而α的影响较小,同时模型仿真再现了交通流状态的动态衍化过程。通过试验验证,该模型仿真得到的Q-ρ关系曲线和实际交通流一致,且可模拟再现实际交通流的失稳、阻塞演化、走走停停等非线性交通流现象。
