一种扩展的BML模型及其数值模拟

An Extended BML Model and Simulation

本文在具有广泛影响意义的二维元胞自动机交通流模型——BML模型的基础上,重新考虑了城市实际交通流的特点,将一种与车辆相关的OD(Origin and destination)属性引入其二维网格中,建立了一种扩展的BML模型,并在数值模拟的基础上对其进行了验证和讨论。

Based on the famous two dimensional traffic cellular automata model--BML model, thinking over the real traffic flow characters of city traffic, the paper incorporates the origin-destination （0D） effect of vehicles to the BML model and presents an extended model. Based on real traffic data and simulations, the paper gives analyses and discussions of the extended model.
