Abstract
This paper aims to optimize the road network structure of open residential areas in China. Firstly, the nonlinear coefficient R0 = t3/T is used to study the road condition, using Matlab programming to calculate road network saturation LOS, establish a reasonable evaluation index system of community opening. Then the theoretical model of road resistance function is established, the influence coefficient η of each factor is determined, the traffic influence degree model is established, and the vehicle passing model is obtained. Finally, three different types of community A, B and C are constructed, and then traffic simulation is carried out according to Vissim software. The conclusion is that the degree of road traffic pressure relief is the largest in one type of community, and the least degree in type B community.
