Abstract

This study evaluates the use of an advanced traveler information system (ATIS) to promote the use of alternative routes and improve local road network performance during work projects. The ATIS system was implemented on a four-lane divided highway in Edgerton, Wisconsin during a bridge reconstruction. Field comparisons between ATIS presence and absence showed different diversion patterns in northbound and southbound directions associated with traffic delay. Drivers remained on the freeway when the displayed delay was less than 15 minutes while more drivers chose to leave the freeway with displayed delay greater than or equal to 15 minutes. A linear regression analysis showed that freeway volume, ramp exiting volume during normal days, and delay time were significant variables associated with a high diversion rate. The ATIS also was shown to perform effectively in increasing the work zone operational capacity.
