城市道路交通的系统化设计思路

Systematic Design Approach to Urban Road Traffic - A Case Study of the Chengdu Tiedong Express Line

摘要:

城市道路交通系统构成复杂，交通节点作为城市道路交通系统的重要组成部分，其承担的交通转换功能对整个路网的系统运行效率起到关键支撑作用。以成都铁东快线方案设计为例，对相关道路功能和节点交通主流向进行了分析，提出在城市建成区，在道路交通系统的建设受周边用地、已建设施等空间条件限制时，以“分解流向、系统实现”为系统化设计思路，通过对周边路网和交通节点的系统设计来实现高效交通转换。同时，提出了符合城市空间发展要求和交通转换需求的道路交通系统化设计方案，为今后建成区道路交通系统化设计提供参考。

Abstract:

The urban road traffic system is complex in composition. As an important component of the urban road traffic system, traffic nodes play a key supporting role in the operational efficiency of the entire road network due to the traffic transfer functions. Taking the scheme design of the Chengdu Tiedong Express Line as an example, the relevant road functions and the mainstream traffic direction of the nodes are analyzed. It is proposed that in the built-up area of a city, when the construction of the road traffic system is restricted by spatial conditions such as surrounding land and existing facilities, with the systematic design concept of "decomposing flow direction and system implementation", the efficient traffic conversion is achieved through the systematic design of the surrounding road network and traffic nodes. At the same time, a systematic design scheme for road traffic that meets the requirements of urban spatial development and the demands of traffic conversion is proposed, providing a reference for the systematic design of road traffic in built-up areas in the future.
