首先通过因子分析法,提取出了道路通行能力的3个主因子:流量因子、交通通达度因子和延误时间因子,并建立了基于因子分析的道路通行能力评价模型;然后按小区结构不同将其分为4种类型,根据VISSIM软件仿真模拟模型,得到不同类型小区开放前后的车辆数量、平均车速、平均行程时间和平均延误时间的数值,通过数值的横向和纵向的对比,得到开放小区会降低主干道上的车流量,但在某些道路级别和车道数目的情况下也可能造成主干道上的车速降低、平均行程时间提升和平均延误时间提升等结论.
Firstly, factor analysis is used to extract three main factors of traffic capacity: traffic factor, traffic accessibility factor and delay time factor, and to establish a road capacity evaluation model based on factor analysis; and then according to the different residential structure According to VISSIM software simulation model, the number of vehicles, average speed, average travel time and average delay time before and after opening of different types of residential area are divided into four types. By comparing the horizontal and vertical numerical values, the open residential area will be reduced Traffic volume on the main road, but at some road levels and the number of lanes may also lead to the conclusion that the speed on the main road is reduced, the average journey time is increased and the average delay time is increased.
