THE BENEFIT OF ATIS ON CONSUMER SURPLUS : A MIXED-EQUILIBRIUM MODEL WITH ELASTIC DEMAND

In this paper, the authors present a mixed-equilibrium model for elastic total demand and elastic market penetration of route planning and guidance (RPG) services. The model assumes that all drivers are to follow the stochastic user equilibrium conditions with the equipped drivers having lower travel time perception variations. The model is formulated using the variational inequality approach. The authors provide a methodology for investigating the effect of RPG services on network consumer surplus. They also determine the equivalent capacity expansion effect of RPG services and studies the trade-off between network capacity expansions versus traffic information service improvements. A numerical study demonstrates the methodology.
