ANALYSIS OF THE STABILITY OF TRAVEL TIMES ON TRAFFIC NETWORKS USING ATIS

Anticipating the proliferation of advanced traveler information systems (ATIS), the authors analyzed the effect of providing advanced knowledge of future expected travel time to drivers in terms of stability and variance (day-to-day consistency) of these travel times on the network's links over time. The behavior of individual drivers was modeled using the concept of a dynamic user equilibrium. The effect of adaptive traffic signalization and predefined fixed signal plans, combined with dynamic routing on travel time, were compared and contrasted. Results revealed that even if a high percentage of drivers rely on ATIS data, stable and relatively efficient link travel times can result. The analysis demonstrates how using adaptive contol in an ATIS environment supports the provision of optimal signalization given the anticipated flow.
