基于微观仿真的城市公交专用道设置研究

为研究公交专用道对交通运行情况的影响，以合肥市望江路为例，以实测数据为基础，通过微观仿真软件Vissim构建微观交通模型，提出以最大排队长度、延误作为节点评价指标，以路段运行速度作为路段评价指标，以路网平均运行速度作为路网评价指标的评价体系，从节点、路段、路网层面，定量化评价公交专用道设置对于交通运行情况的影响，为城市决策者提供参考。

Research on Setting of Urban Bus Lane Based on Micro Simulation

Taking Wangjiang Road in Hefei as an example, based on the measured data, a micro traffic model is constructed through the micro simulation software VISSIM. An evaluation system is proposed by taking the maximum queue length and delay as the node evaluation index, the road section operation speed as the section evaluation index and the average operation speed of the road network as the road network evaluation index. The impact of setting the bus lane on the traffic operation is quantitatively evaluated from the levels of the node, the road section and the road network so as to provide the reference for urban decision-makers.
