猎德大道系统对广州中心城区交通流量的影响分析

Analysis on Influence of Liede Avenue System on Traffic Flow in Central Area of Guangzhou

随着我国城市化、机动化、市场化的高速发展,城市道路资源短缺,机动车保有量激增,大城市人口密度加大,城市化带来的城市用地规模迅速扩大,使得城市交通面临严峻的挑战。从整体上来研究城市道路网络的结构,从道路网络结构来分析城市道路的交通功能,是对城市路网进行改善的一种有效方法。首先,对广州市骨架道路的构成和特性作简要的介绍;在此基础上,以广州市猎德大道系统为实例,对项目影响区广州核心城区路网结构的特征进行了分析,依据各种预测模型对项目建成后对路网的交通流量进行了预测;最后,根据研究结果对猎德大道系统建成后对广州市中心城区的交通影响程度进行分析,并提出了政策性建议。

With the high-speed development of urbanization, motorization and marketization in China, the resource shortage of urban road, the increasing amount of vehicle, the increasing density of metropolis population and the rapid expanding of urban land scale brought from urbanization make the urban traffic faced with serious challenge. It is an efficient method to improve the urban road network by integrally studying the structure of urban road network and analyzing the traffic function of urban road from the structure of urban network. The article briefly introduces the composition and character of trunk roads in Guangzhou City. On this basis, the article analyzes the character of the road network structure in the core area of Guangzhou by a case of Liede Avenue in Guangzhou. According to the forecast models, the article forecasts the traffic flow of road network after the project completion. The article analyzes the influence of Liede Avenue after completion on the traffic of the central area of Guangzhou, and puts forward the policy proposal.
