交通流元胞自动机模型中粒子密度的标定

Calibration of the Particle Density in Cellular-Automaton Models for Traffic Flow

Masahiro Kanai

摘要:

我们在交通流的元胞自动机模型中引入了细胞大小的密度依赖性,这使得现实世界的现象和模拟中观察到的现象之间有更精确的对应关系。此外,我们给出了一个显式的粒子密度的校准,特别是对于非对称简单排斥过程的一些更新规则。因此,我们发现,本方法是有效的,因为它再现了一个现实的流量密度图。

英文摘要:

We introduce density dependence of the cell size in cellular-automaton models for traffic flow, which allows a more precise correspondence between real-world phenomena and what observed in simulation. Also, we give an explicit calibration of the particle density particularly for the asymmetric simple exclusion process with some update rules. We thus find that the present method is valid in that it reproduces a realistic flow-density diagram.
