Abstract

This paper aims to analyze the effect of open community system on road traffic. Based on the evaluation index system of the impact of community opening on road traffic, a space-time dynamic analysis model of vehicle traffic capacity is established to describe the urban road traffic situation. Firstly, considering the road condition, safety, vehicle type, traffic distribution and other factors, nine indexes for evaluating the impact of community opening on road traffic are established, with the calculation formulas listed. And then through the fuzzy comprehensive evaluation, the comprehensive index for evaluating the road traffic condition is obtained. Secondly, in terms of the road traffic situation, a space-time dynamic analysis model of road traffic capacity is built using mechanism analysis method. This model takes the total space-time resources and the individual space-time consumption of traffic into account. By comparing the influence of the change of the intersections number and the total lanes area on the total space-time resources of urban road facilities before and after the opening of the community, the relationship between the amount of resources and the factors such as traffic density and speed is calculated and analyzed. Finally, various cases are used to analyze the impact of community opening on road traffic under different road network conditions, with the redundant variable assumed as a single variable for quantitative research. The results show that the opening the central community has more positive effect than opening the block community on the same road section. For communities with the same structure, the community opening with larger traffic flow tends to influent more, while the influence of the community with particularly small traffic flow can be neglected.
