摘　　要：基于改进的BPR模型研究城市住宅区的开放对周边道路通行的影响.首先构建封闭小区开放对城市道路通行能力影响的评价指标体系,运用Spss和Matlab软件进行了定量分析,选取了路径数量、道路基础设施面积、非直线系数和交叉路口阻塞率等4个评价指标,建立了改进的BPR模型,通过计算交通指数研究封闭小区开放对提高周边道路通行能力的影响,最后进行实证分析,验证了该模型的可行性.Based on the neural network model,this paper studied the impact of the opening of urban residential areas on the surrounding road traffic.Firstly,the evaluation index system of the impact of the closed community opened on the urban road capacity is constructed,and the quantitative analysis is carried out by using SPSS and MATLAB.Four evaluation indexes are selected,including the number of paths,the area of the road infrastructure,the non-linear coefficient and the blocking rate of the intersection.The improved BPR model is established.Through the calculation of the traffic index,the opening of the closed community is studied to improve the surrounding roads.Finally,the feasibility of the model is verified by empirical analysis.
