城市道路网布局优化研究——以苏州相城区为例

Study on Layout Optimization of Urban Road Network—Taking Suzhou Xiangcheng as an Example

随着城市经济发展,城市不断扩张,机动车保有量大幅增加,现有城市路网密度低,结构不合理,已难以满足城市交通需求,造成交通拥堵。通过城市道路网布局优化原则,对其进行优化研究,包括路网结构、路网密度、路网级配和路网面积率,并通过案例对研究方法进行验证。能够对道路前期的规划与设计提供必要的参考依据,具有较好的工程实用意义。

With the development of urban economy, the continuous expansion of the city, the number of motor vehicles increased significantly, the existing urban road network density is low, the structure is unreasonable, it is difficult to meet the urban traffic demand, resulting in traffic congestion. Through the optimization principle of urban road network layout, this paper studies the optimization, including road network structure, road network density, road network gradation and road network area ratio, and verifies the research method through a case. It can provide necessary reference for the early planning and design of the road, and has good engineering practical significance.
