Abstract:

?为了精确解析城市公交车和社会车辆混合运行的状态,在基本路段车速模型适用性分析的基础上,引入公交车流量、社会车辆流量、公交车比例等参数,建立了改进的混合机动车运行速度模型,分别选取单向二车道和单向三车道路段进行交通试验调查,采用Metrocount5600气压管式车辆分型系统进行数据采集并用于改进模型的参数标定,并分别建立了2种车型的速度差模型,提出了路段混合车流3种不同交通运行状态的评价方法。研究结果表明:同等车流量情况下,不同公交车比例对社会车辆速度的影响表现为3个显著的变化区间;随着路段饱和度的增加,社会车辆和公交车之间的速度差呈现出从几乎不变、快速缩小到接近于零3个较为明显的运行状态;考虑车流组成中公交车比例的变化可以细化路段车流畅通状态、拥堵形成状态以及拥堵状态的判别。
