中文摘要:
      为了给中小城市建立低碳交通体系提供理论依据,利用美国联邦公路局(FHWA)微观仿真软件TSIS/CORSIM,并结合广东省清远市中心城区的交通调查,建立了清远中心城区路网交通仿真模型,对以现状交通流量为基础设定的5个情景方案进行了仿真研究.结果表明: 随交通流量的增大,路网的交通排放增加,当增大到1.5倍时,车辆每公里的HC,CO,NOx和CO2排放分别上升8%,12%,12%和29%,当交通流量增加(1.5倍)导致交通拥挤时,额外燃油消耗为225 L,额外CO2排放为518 kg,占总排放的16.3%.
英文摘要:
      In order to provide the theory basis for a low carbon transportation system set of small and medium-sized city, traffic simulation network model of the center of Qingyuan city was built with TSIS/CORSIM microscopic simulation software of the America Federal Highway Administration and combined with the central area traffic investigation of Qingyuan city ,Guangdong Province, and simulation study was made for five scenarios based on the traffic volume. Results showed that the network traffic emissions increase with the rise of traffic flow; emissions of HC, CO, NOx and carbon dioxide per kilometer increase by 8%, 12%, 12% and 29%, respectively when traffic flow increase to 1.5 times; Fatherly, when the increase traffic flow(1.5 times) led to traffic congestion, extra fuel consumption(225 L) and extra CO2 emissions(518 kg) are brought out. The extra CO2 emission is 16.3% of the total discharge.
