A dynamic alternate route strategy for traffic networks

A dynamic alternate route strategy is developed for a typical node of a traffic network. The strategy compares the queue length at the node against an optimal threshold value. When the threshold is exceeded, some of the traffic is diverted along an alternate more costly route to its destination. The...

Summary:A dynamic alternate route strategy is developed for a typical node of a traffic network. The strategy compares the queue length at the node against an optimal threshold value. When the threshold is exceeded, some of the traffic is diverted along an alternate more costly route to its destination. The local node level strategy is easily implemented in real time and is also adaptive to changes in route capacities, input rates or the relative delays along the alternate route. It is also suitable for use in a decentralized routing strategy for large networks.
