城市交通组织优化实践——以太原市为例

Practice of Urban Traffic Organization Optimization: A Case Study in Taiyuan

交通组织优化是城市交通管理的重要技术手段。为研究交通供给策略与交通需求管理在城市交通组织优化中的指导作用,对交通供给策略、交通需求管理和交通组织优化的概念进行解析。然后,结合交通供给策略与交通需求管理在太原市城市交通组织优化过程中的应用,对比分析增加交通供给与控制交通需求前后的道路交通量变化及交通组织优化效果。最后指出,增加交通供给的作用时效比控制交通需求短暂许多,在实践中应采取"合理控制交通需求为主、适度增加交通供给为辅"的交通组织优化措施。

TOO（Traffic Organization Optimization） is an important technical method for urban traffic management.To study the effectiveness of TSS（Transportation Supply Strategy） and TDM（Travel Demand Management） in TOO on urban roadways,this paper analyzes these three concepts.Then,combined with the application of TSS and TDM in Taiyuan,this paper compares the change of traffic flow and the effectiveness of TOO.Finally,this paper indicates that it is less time-consuming to increase TSS than controlling TDM on the roads of Taiyuan city.The paper also stresses that urban traffic management should reasonably control travel demand first for the traffic optimization supplemented by roadway capacity expansion.
