考虑驾驶员具有不同的驾驶特点,利用元胞自动机NS模型和FI模型的混合模型模拟交通流状态的演化网络,模拟结果表明:混合比例系数虽然对道路交通流的流量和平均速度影响很大,但是不改变交通流状态演化网络的无标度特性;网络模型的无标度特性呈几何分布。
Considering different driving characteristics of drivers,a hybrid model based on NS and FI cellular automaton model was presented to simulate the evolution network of traffic flow states. The results show that the proportion of mixed coefficient has an great influence on the flow and the average speed, but it does not change the state of traffic flow evolution of the network scale-free properties;Evolution of traffic flow with scale-free topology was geometric distribution.
