中文摘要：

本文利用微观仿真软件（VISSIM）对研究对象进行微观交通流模拟，并将得到的车辆运行状况数据用数据库方式输出，转换后作为综合模式排放模型（CMEM）计算油耗和排放所需要的输入文件。用该方法以南京市太平北路为研究对象，模拟将该路段的最外侧混行车道改造为公交专用道后对交通流及油耗和排放的影响。模拟结果表明：该设置明显改善了公交车的交通流运行情况，并能够有效减少公交车的燃油消耗及尾气排放；但是对整体路段的总体机动车而言，该设置使得路段平均燃油消耗率及HC、CO和NOx的平均排放因子少量增加。

英文摘要：

By simulating with VISSIM software, the object＇s vehicle running status data is output in database way, and then the data was used as CMEM model＇s input file to calculate the vehicle fuel consumption and exhaust emissions. With this approach, the authores selected Taiping north road in Nanjing as a study object, and assumed that its kerb mixed lane was reconstructed as a bus lane and simulated the section on the basis of field survey. The reconstruction＇s influences on the traffic flow, fuel consumption and emission were also analyzed and discussed. Simulation results showed that this setting can significantly reduce public traffic vehicles＇ delays, fuel consumption and emission. But for all the vehicles on the whole road section, vehicle average specific fueI consumption and average emission factor will have a little increase.
