将微观交通仿真模型VISSIM和微观尾气模型CMEM衔接整合起来,选取南京市城东干道九华山隧道一段为研究对象,建立隧道机动车尾气模拟平台,对交通运行状况和尾气排放量进行评价。在调查分析隧道机动车尾气现状的基础上,模拟比较分析限速及诱导标志设置等不同交通控制与管理措施对隧道尾气污染的影响,并就新庄立交改造前后机动车尾气的排放进行了评价。
The microscopic traffic simulation model VISSIM and the microscopic tail gas model CMEM convergence are combined to select the section of Jiuhuashan tunnel in east of Nanjing as the research object. The tunnel motor vehicle tail gas simulation platform is established to evaluate the traffic status and exhaust emissions. Based on the investigation and analysis of the status quo of tunnel motor vehicle exhaust, the influence of different traffic control and management measures such as speed restriction and induced sign setting on tunnel exhaust gas pollution was simulated and compared. The emission of vehicle exhaust before and after the transformation of Xinzhuang Interchange was evaluated.
