| 摘 要： | 交通大气环境影响分析是交通可持续性发展研究中重要的工作内容,对于道路交通规划与管理具有重要意义。采用微观交通仿真软件TSIS中的CORSIM排放模型,研究机动车车型、平均车速、车辆加减速度与污染物排放率的相关关系,提出了道路交通路网机动车大气污染物排放总量计算方法。以某城市主干道相关区域路网作为研究对象,将道路条件、交通流量、交通管理控制措施等因素集成于仿真系统中,研究机动车对相关路网道路环境的影响,利用TSIS彩色成图技术表现出路网中各个路段大气污染严重程度,评价方法直观、生动。

| Abstract: | Analyzing the influences of road traffic to atmospheric environment is an necessary work in the transportation sustainable development research,which is important on road traffic plan and management.First,the CORSIM emissions model of Traffic Software Integrated System(TSIS)is use to establish the correlations between vehicle types,average speed,acceleration and the pollutant emission rates.Secondly,the computational method of vehicle's air pollutant emissions total quantity in the road network is proposed.Finally,taking a city network as an example,the informations is integrated into a simulation system of the road conditions,the traffic flow,traffic management measures etc.in order to study vehicle's influence on the related road network and road environment.By means of TSIS color image technology,the air pollution degree of each road section in the road network is showed directionally.Hence,the evaluating method is direct-viewing and vital. |
