The Influence of Community Opening on Road Capacity Based on Cellular Automata Model

摘要

This paper models and analyzes the cellular automata model by exploring the influence of community opening on road traffic capacity in order to make full use of the potential capacity of urban transportation network and alleviate urban traffic contradiction. Firstly, this paper establishes comprehensive evaluation index system of traffic condition by literature review, which can judge the advantages and disadvantages of community opening. And then, this paper establishes the mathematical simulation model based on the cellular automata theory, and gets the data affecting traffic volume around the open plot. Also it establishes the empirical formula of road capacity surrounding the opening area by SPSS multiple regression. Finally, by analyzing the example and discussing six types of communities, this paper gets that whether the community opening can improve road capacity is closely related to community structure, internal road structure, surrounding road structure and traffic flow, and finds it is much better to open the community with surrounding road for multiple lanes.
