元胞自动机模型是从离散模型角度对交通流进行模拟,但当前在交通流的模拟上元胞自动机还多集中在局部路段的分析上,少见与城市整体范围内的结合。本文通过基于影响车辆的若干因素建立的车辆生成灭失模型、影响车辆行使路线的引力度模型和车辆运动模型三个方面分析,初步进行元胞自动机在城市整体范围内交通流模拟的探讨,从而希望为城市交通流的模拟分析提供一个新的操作方法。
Cellular automata model simulates traffic flow from the perspective of discrete model. However, the current cellular automata in traffic flow simulation are mostly concentrated in the analysis of partial link, which is rare in the whole city. In this paper, based on several factors that affect the vehicle to establish the loss of vehicle model, the impact of the vehicle routing of gravity model and vehicle motion model analysis of three aspects, the initial cellular automata in the overall urban traffic flow simulation to explore Hope to provide a new operation method for the simulation analysis of urban traffic flow.
