Simulation Analysis of Vehicle Emissions in Jiuhuashan Tunnel Based on the Software VISSIM

An integrated microscopic traffic-emission simulation platform was developed by using the microscopic traffic simulation model VISSIM and the comprehensive modal emissions model(CMEM).The paper selected the Nanjing Jiuhuashan Tunnel to build up the traffic simulation network.So its traffic performance and vehicle emissions can be evaluated.On the basis of the current vehicle emissions,the developed platform can analyze and evaluate the different traffic control and management strategies of Jiuhuashan Tunnel(mainly the speed limit and induction sign).Meanwhile,it also compared vehicle emissions before and after the reformation of Xinzhuang Interchang,thus evaluating the rehabilitation program.
