摘要：为解决机非混行造成的交通低效问题，构建单向平面分流路网，即以机动车干路单向交通组织为基础，以机动车支路和自行车、公交专用路双向交通组织为辅助的公交专用、机非分离的路网模式。首先，采用VISUM，VISSIM模型，对单向平面分流路网与传统混合路网的路网特性、交通运输效率进行分析，结果表明，分流路网在交通绕行、转向比例方面与传统混合路网基本一致。其次，在对两套路网体系进行优化设计的基础上，通过仿真分析，得出单向平面分流路网的运输效率远高于传统混合路网。最后指出，将干路单向化处理，发挥单向道路的横向可穿越特性，辅以减少干路绕行的支路体系，是单向平面分流路网实现高效运行的关键。

Abstract：To solve the low capability problem caused by the mixed traffic of motor vehicles and bicycles, a one-way road network is proposed, which separates bus, bicycle, and motor vehicle traffic and allow two-way flows for bike and bus on exclusive lanes. The proposed network is evaluated by VISUM and VISSIM models. Specifically, the models simulate the characteristics of one-way diversion road network and traditional road network and compare the transportation efficiency between the two networks. The simulation results show that the new road network has generally the same traffic detour volume and turning ratio compared with the traditional road network. The design optimization of both roadway network shows that the transportation efficiency of new road network is much higher than that of conventional mixed traffic road network. Finally, this paper indicates that the key point to achieve the high-efficiency operation of one-way diversion road network is to separate bus, bicycle, and motor vehicle on arterial road, which enhances the capability for through traffic of one-way road, and at the same time reduces the traffic detour on minor road system.
