摘要
城市道路交通流通常以混合机动车流为主 ,对混合交通流进行分析 ,要有一个统一的标准来计量道路上行驶的车辆。本文从定义动态车长入手 ,提出了基于通行耗时、分行驶状态计算车辆折算系数的计算方法 ,并利用该方法对城市交通流调查数据进行了计算 ,得到的城市道路机动车交通流的车辆折算系数值合理。
The traffic flow on the urban roads usually is the mixed traffic stream. To analyze the mixed traffic volume, a unified standard of the vehicles is needed. The paper put forward the definition of the dynamic length of vehicles. Based on the passing time, the paper proposed the calculation method of the vehicle conversion coefficients under different driving state. Then the vehicle conversion coefficients are obtained using the traffic survey data.
