摘要
简述了快速路网导行控制的基本原理,提出了以可变信息标志(VMS)为诱导手段的快速路网导行控制方法.导行控制以经典的METANET模型作为快速路交通网络模型,采用非线性最优控制方法进行控制问题的建模,采用遗传算法求解优化问题.仿真算例显示了导行控制的有效性.
First, this paper presents the concept of the traffic routing control. Then it proposes a routing control approach based on variable message sign (VMS) for freeway networks, with the adoption of the classic network flow model METANET. The routing control problem is formulated as a nonlinear discrete -time optimal control problem, which is solved online by genetic algorithm (GA). Traffic simulation of a sample network shows the effectiveness of the proposed routing control approach.
