城市复杂动态交通自适应局部路由策略

Adaptive Local Routing Strategy in Complex Urban Dynamical Traffic Networks

针对实际交通动态网络情况,提出一种自适应局部路由动态诱导策略.该策略不仅考虑了静态路网结构信息,同时也结合了车辆等待排队时间等因素,通过引入可调节参数,可以给定车辆传输的实际路径,直至车辆到达目标节点.数值仿真试验表明,与已有的局部路由策略和随机游走策略相比,该自适应局部路由算法能更有效地增加网络的通行能力.

In view of the actual traffic dynamical road networks,a new adaptive local routing strategy is proposed for inducing vehicles.The adaptive local routing strategy not only considers the static road network structure information,but also combines the waiting queue time of the vehicles.By introducing the adjustable parameters in the new routing,the actual path of the vehicles can be given until the vehicle reaches the target node.Numerical simulations show that the proposed adaptive local routing algorithm can effectively increase the traffic capacity of the traffic network,compared with the existing local routing strategy and the random walk strategy.
