基于交通仿真对开放小区道路通行的探究

Research on Road Traffic of Open Residential Area Based on Traffic Simulation

针对小区开放对道路通行能力的影响,借助于路段饱和度、交叉口饱和度、排队长度、交通流、平均速度及延误时间六项指标,建立车辆通行模型和交通仿真模型.从不同评价角度进行定量分析.用VISSIM软件对三种不同开放类型的小区周围交通进行仿真模拟,得出最优的小区结构.

According to the influence of open area on road traffic capacity, the vehicle trattic model and traffic simulation model are established by means of six indexes： road satura- tion, intersection saturation, queue length, traffic flow, average speed and delay time. Analyze quantitatively from different evaluation perspectives. VISSIM software is used to simulate the traffic around three different types of open spaces, and the optimal cell struc- ture is obtained.
