摘要
在对车辆个体行为研究的基础上,针对城市商业热点对交通流的导向性影响,引入商业热点吸引子的概念并合理概化其作用模式,利用元胞模拟这一非线性过程研究工具,对具有双向通路的准二维交通流进行了初步建模及模拟计算.计算结果表明,商业热点吸引子的引入以及基于元胞方法的交通流模拟可以反映出较为复杂的城市交通基本特征,是交通流模拟的有效研究手段.
Based on the study of individual vehicle motion, the focus is put on the guiding influence caused by commercial hotspots and a concept named commercial hotspots attractor is introduced. By using the cellular automata method which is a nonlinear math tool, the calculation is carried out to simulate the quasi-2D and bi-directional traffic flow. The results show that the cellular automata method introducing the commercial hotspots attractor is an effective solution to simulate more complex urban traffic features.
