A SIMPLE MODEL FOR ROUTE GUIDANCE BENEFITS

This paper concerns the benefits from vehicle route guidance in urban networks. A continuum approach is used to analyze an idealized corridor in which a freeway is superimposed over a dense grid of surface streets. The main role of route guidance is to divert traffic from the freeway whenever its marginal cost exceeds that of the street system. At low speed more users would choose the freeway resulting in congestion, and the potential benefits of route guidance are relatively high. However, as street speed increases and approaches that of the freeway, route guidance would be of less value as more of the motorists would be choosing the city street on their own. It is shown that benefits are reduced when the freeway network is dense.
