摘要
在Logit动态的基础上建立了收费和通行能力的联合控制模型,通过控制时变的道路收费水平和通行能力,优化交通流的演化轨迹,使交通系统达到最优。通过简单的算例,在Logit动态的基础上对道路中的交通流进行分析和预测,进而对车辆进行诱导,从而达到交通管理的目的。
In the traffic system,because of the incomplete information,each of the road users will measure the real traffic with random deviation inevitably,and select path with random.So it＇s more appropriate to use logit dynamic to describe the evolution of traffic flow.In this article we established a joint optimization model of road tolls and capacities using the optimal control theory based on logit dynamic,which can optimize transportation system by controlling the level of time-varying road pricing and capacity.Through a simple example,we give analysis and prediction to traffic flow based on logit dynamic,and provide theoretic support for guidance strategy.
