研究一个由快慢两条车道组成的交通流模型, 快车道上的车辆可以根据瞬时交通情况进入慢车道. 将基于速度梯度的交通流连续模型应用到每条车道上, 研究车流的小扰失稳和走走停停等非平衡特性. 还研究了模型线性稳定的充要条件, 并用算例进行验证.
A traffic flow model consisting of two fast and slow lanes is studied and the vehicles in the fast lane can enter the slow lane according to the instantaneous traffic conditions.The continuous traffic flow model based on the speed gradient is applied to each lane to study the small disturbance instability Stop-and-go, etc. The necessary and sufficient conditions for the linear stability of the model are also studied and validated with examples.
