基于BML模型,将城市道路设置为10×10条道路的二维静态网络,在开放性边界条件下,研究不同消失概率、车辆长度、最大速度及红绿灯周期与绿信比等影响因素对东西向车道和整个网络交通流特性的影响,再现与实际交通相一致的非线性现象。
Based on the BML model,the two-dimensional static network model with 10 west- east-orientation roadways and 10 south-north-orientation ones is established. Under the open boundary condition, the characters of west-east-orientation roadways and the whole network for traffic flow are analyzed with the conditions of different disappearance probability, vehicle length, maximum velocity, traffic lights period and green-signal ratio. Moreover,the nonlinear phenomena are reproduced according with the real traffic.
