摘要

In this paper, we mainly study the influence of the community opening on the surrounding road traffic, and correspondingly, build a model for the vehicle traffic. Firstly, focusing on the overall road network structure of the community and its surrounding area before and after the community opening, we establish the Variable Cell Transmission Model (VCTM model). In this model, the roads will be segmented and a new concept - traffic flow is proposed based on the transfer characteristics of cellular. Furthermore, we characterize the road traffic capacity by means of three traffic flow state evaluation indexes which are the average travel speed, the traffic impedance and the congestion delay. Secondly, with the help of MATLAB, we abstract the target community network structure into a complex network model, and then by inputting the three description parameters, namely the degree distribution, the average path length and the clustering coefficient into VCTM model and using the VISSIM software for simulation, we get the output of the three traffic flow state evaluation indexes, thus establishing the community vehicle traffic model. Then, corresponding to the road network structures of different communities and their different surrounding environments, five complex network models are constructed, which are respectively named the closed community model, the regular network model, the random network model, the small world network and the scale-free network model. Among those models, the closed community model corresponds to the community opening anterior network structure and the other 4 characterize the road network structures after the opening of community. By inputting the 5 kinds of complex network traffic model into the community vehicle traffic model, we can quantitatively compare the effects of the opening of different types of residential area on the road traffic according to the results of the model. the influence of the opening and the opening of each type on the road traffic was quantitatively compared. Through analysis, we can get that the regular network model traffic carrying capacity is the worst, while the scale-free network traffic carrying capacity optimal. Finally, through the comparison and analysis of the above results, we get the effects of the opening of different types of community on the road network structures and the road traffic capacity. Based on the results we have got, we put forward several rationalization proposals about the community opening to the urban planning and traffic management department.
