The goal of this study was to provide a better understanding of the impacts of route guidance on urban arterials and networks controlled by traffic signals. Control and timing strategies to handle diverted traffic from the freeways to surface streets were developed and tested through simulation on real-life networks. These strategies showed that for a small number of diverted vehicles, optimal timing plans for favoring the diverted routes improved the performance of diverted traffic without significant adverse impacts to the rest of the network.
