摘要
提出了一种基于三相交通流理论的驾驶决策交通流仿真模型。该模型采用驾驶决策函数替代由Kerner等人提出的KKW模型中目标速度函数,在新模型中将驾驶行为分为自由流驾驶模式、同步流驾驶模式和堵塞流驾驶模式,三种模式会根据道路的实际交通情况进行切换。基本图和时空分析结果表明,提出的模型符合实际的交通观察。
This paper presents a new driving decision-making simulaton model based upon three-phase traffic flow theory by means of improving the KKW model. In the new model, the destination velocity used in the KKW model is substituted by the driving decision-making function and three driving modes are proposed, namely the free flow driving mode, the synchronization driving mode and the jam driving mode which can switch into each other according to the actual traffic conditions. Numerical analysis indicates that the new model is in compliance with the observations of authentic transportation.
