城市轨道交通施工期交通疏解系统化设计探索

Exploration on Systematic Design of Traffic Relief during Construction Period of Urban Rail Transit

城市轨道交通施工期间对城市交通运行的影响主要表现在临时疏解道路和周边路网两方面。目前交通疏解设计重点关注部位集中于站点,没有对沿线和路网状况做统一考虑。从系统角度看,交通疏解除了要解决被占道路的保通外,还要能评估疏解方案对路网的影响。为此通过对交通组成特性、临时疏解道路承担的交通量、局部道路网的交通调配、路网受影响范围的分析,提出了交通疏解系统化设计的观点和方法。

The influence on the operation of urban traffic during the construction of urban rail traffic is mainly manifested in the temporary relief road and surrounding road network. At present, the focus of traffic relief design is on the rail transit stations. There is no unified consideration of the situation along the line and road network. From the system point of view, the traffic relief can not only solve the problem of smooth traffic of the occupied road, but also evaluate the influence of relief scheme on the road network.Therefore, by analyzing the characters of traffic composition, traffic volume carried by temporary relief road, traffic allocation of local road network and influence range of road network, the viewpoint and method of traffic relief systematic design are proposed.
