发布时间：2019-04-08 08:55
【摘要】：针对城市中心道路机动车流量增加带来的大气环境污染问题,探讨区域机动车流量与污染物之间的关系。分析交通污染源强、道路几何条件和气象条件,建立基于ARCGIS重点区域机动车通行容量模型,用于计算城市重点区域机动车通行量阈值。以桂林市城市中心主要道路为例,分析区域不同空气质量等级下交通量限值,为环境及交通管理提供了决策支持依据。
[Abstract]:In order to solve the problem of air pollution caused by the increase of vehicle flow in urban central road, the relationship between regional motor vehicle flow and pollutants is discussed. Based on the analysis of traffic pollution source, road geometry and meteorological conditions, a vehicle traffic capacity model based on ARCGIS is established to calculate the threshold of traffic volume in key urban areas. Taking the main roads in the city center of Guilin as an example, this paper analyzes the traffic volume limits under different air quality grades in the region, and provides the basis for decision-making support for the environment and traffic management.
