【摘要】 随着我国机动车拥有量及道路交通量的急剧增加,交通污染排放急剧上升,机动车排放已成为空气污染的重要原因之一。在此前提下,论文对城市路网中的机动车排放问题进行了研究,主要研究内容用有:(1)分析了目前我国城市交通机动车排放污染的现状及机动车排放污染物的危害程度,确定了机动车污染排放的监测项目为CO、FOC、NOX、PM10、SO2和PM2.5。并对机动车排放因子的各种模型进行了归纳分析,选择将机动车分为轻型车、中型车、货车和公交车四类进行排放分析。(2)对于平面交叉口机动车排放规律的研究,考虑信号控制对排放的影响,综合分析机动车在交叉口的运行特性,将机动车排放分为信号控制交叉口和无信号控制交叉口两种类型,得到交叉口机动车污染物排放监测模型。结合VISSIM仿真软件验证了所建立的模型能够用于交叉口污染物排放监测的研究。(3)对于城市道路机动车排放规律的研究,综合分析机动车在道路上的行驶特征。考虑高峰时段及平峰时段机动车的交通行为有较大差别,建立了平峰时段道路及高峰时段路道路机动车排放监测模型。并利用VISSIM对调查数据进行仿真验证了城市道路机动车污染物排放监测模型的可行性。(4)根据城市路网自身特点、交通排放的影响因素,依据"点—线—面"的思路建立了城市路网机动车污染物排放监测的组合模型,并采用城市路网机动车排放综合测定值来反映机动车污染的综合效应。以南京市鼓楼区铁北片区路网为例对城市路网机动车排放的组合监测模型进行实例分析。
【Abstract】 In recent years,with the rapid increase of the ownership of motor vehicles and road traffic volume,the emissions caused by traffic has been increasing sharply and traffic emissions have become one of the important reasons for air pollution.Under this premise,this paper has studied on vehicle emissions in intersections,and the main research contents of this dissertation included:(1)Analyzed the present situation of vehicle emission pollution and the harm degree of motor vehicle emission pollutants and Identifies the vehicle emissions monitoring projects as CO,VOC,NOX,PM10,SO2 and PM2.5.The various models of vehicle emission factors has also been analyzed and divided into four kinds of vehicles as light vehicle,medium vehicle,truck and bus.(2)When research on the vehicle emission rules of intersection,considering the influence of signal control on emission and analyses the driving characteristics of the vehicles at the intersection comprehensively.The vehicle emission at intersection is divided into two types:signal control intersection and no signal control intersection to build the vehicle emission monitoring model at intersections.The emission simulation model of signal control intersection is built based on VISSIM simulation software to test the model can be used to monitor the emission of pollutants at intersections.(3)When research on the vehicle emission rules of section,analyses the driving characteristics of the vehicles on road sections comprehensively.The model of vehicle emission monitoring in peak period and off-peak period is established due to the different traffic behavior of vehicles during peak and off-peak periods.Then using VISSIM to verify the feasibility of road vehicle emission monitoring model.(4)According to the characteristics of urban road network and the influence factors of traffic quality,the combined model of urban road network vehicle pollutant emission monitoring was established,and taking comprehensive measurement of vehicle emissions to reflect the comprehensive effects of all vehicle pollutants.At last,take road network of Gulou District of Nanjing city north area as an example to utilize the monitoring model.
