基于Synchro仿真的城市交通疏堵应用方法研究 ——以拉萨市柳梧大桥南桥头为例

摘要:

目前解决非系统性城市拥堵普遍采用单点优化和道路线性调整提高道路通行能力的方法，但均缺少系统性。本文提出定性与定量、宏观与微观相结合解决交通拥堵的方法，定性与宏观分析期望“以点带面”的效应，寻求较经济的疏堵方案，最终达到区域路网的联动、交通组织的合理化。定量与微观分析在定性与宏观解决措施的基础上，进行单点或一条路的优化，本文以拉萨柳梧大桥拥堵节点为例，通过Synchro仿真软件进行定量分析，鉴别关键节点的拥堵改善程度，评估疏堵的效果和效益。

Abstract:

At present, single point optimization and linear road adjustment are generally adopted to solve non-systematic urban congestion, but they are not systematic. This paper proposes qualitative and quantitative, macro and micro methods to solve traffic congestion, qualitative and macro analysis is expected to "point to surface" effect, seek for more economic congestion scheme, and finally achieve the linkage of the regional road network, the rationalization of traffic organization. On the basis of qualitative and macroscopic solutions, the optimization of single point or one road is carried out. In this paper, the congestion node of Liuwu Bridge in Lhasa is taken as an example, and quantitative analysis is carried out by Synchro simulation software to identify the congestion improvement degree of key nodes and evaluate the effect and benefit of congestion relief.
