| 摘 要： | 元胞自动机模型是近年刚发展起来的交通流模型,由于其建模简单、易于在电脑上实现及可模拟复杂的非线性交通现象而得到了迅速的发展.本文研究了基于NaSch模型的一维交通流元胞自动机模型,并对模型中随机规则在模拟复杂交通现象中所起的作用进行了分析.通过对NaSch模型和VDR模型的基本图和时空分布图进行分析,得出模型中的随机规则是模拟实际交通流中的很多非线性现象的主要规则.

| Abstract: | The traffic flow model based on cellular automata is developing in resent years. It developed rapidly because that it is easy to model and realize on computer, and can simulate the complex non-linear transportation phenomenon. We study the impact of randomization in the 1D cellular automaton model which is based on the the fundamental diagram and space-time diagram of Nasch NaSch model. Through model and VDR model, the analysis of we obtained that the rule is important for simulating some non-linear phenomenon in real traffic flow. |
