Abstract

The computational problems associated with routing of traffic in congested networks is analyzed. An optimal and a suboptimal, but partially decentralized approach is presented. In the decentralized case infrequent updates of relative costs are allowed to give aggregate information about congestion downstream, and optimal controls are re-calculated with the horizon pushed-back at each update time.

拥挤交通网络中路由策略的集中与分散计算
分析了拥塞网络中与流量路由相关的计算问题。提出了一种最优和次优但部分分散的方法。在分散的情况下,相对成本的不频繁更新允许给出关于下游拥塞的汇总信息,并且在每次更新时重新计算最优控制,并将水平推后。
