ROUTE CHOICE AND ADVANCED TRAVELER INFORMATION SYSTEMS ON A CAPACITATED AND DYNAMIC NETWORK

The objective of this paper is to examine the informational assumptions embedded in traffic simulations and to assess how these assumptions affect simulation results. The paper examines the hypothesis that increasing market penetration can lead to a decrement in network performance. The paper proves, for a simple parallel network, that increasing the market penetration of accurate information cannot harm network performance. For this same network the paper shows that increasing the penetration of instantaneous travel time estimates might degrade network performance. The author suggests that ATIS should not be viewed as a strategy for achieving system optimal traffic distributions. ATIS should instead be viewed first as a service to the public, to improve their confidence and comfort in using the system, and second as a means for steering traffic away from dis-equilibrium behavior and toward user optima that utilize alternate routes where feasible.
