混合交通流中公交车对其他车辆的影响

Buses＇ impact on other vehicles in mixed traffic flow

在我国的城市交通中,常规公交和社会车辆混行的矛盾长期存在,严重影响着城市交通的正常运行。文章首先分析公交车的存在对路段交通流特性的影响,然后进一步利用跟车模型计算路段混合车流通行能力,提出在不同公交车比例下的路段通行能力。通过研究和计算分析,说明在混合流中公交车对社会其他车辆的影响是不容忽视的。

The contradiction between the general buses and other social vehicles mixing together is prevalently existing in our country city, that seriously influence urban traffic flow. Firstly the paper analyzes buses＇ influence on traffic flow characteristics and states, further more based on car - following model, the paper analyze urban road capacity in different situations including mixed traffic flow when urban bus accounts for an diverse proportion. At last, as buses have a great effect on the traffic flow characteristics in mixed traffic flow based on the research and analysis, we should emphasizes buses＇impact on other vehicles in mixed traffic flow.
