TRAVELER INFORMATION SYSTEMS Evaluation of UDOT's ATIS Technologies

Abstract

The Advanced Traveler Information System (ATIS) uses communication and information technologies to collect, process, and distribute useful information to the traveling public. ATIS provides timely information on traffic, construction, road conditions, travel times, expected delays, alternative routes, and weather, thereby giving travelers the opportunity to make informed decisions on when to go, what transportation mode to use, and which route to take. The goal of this study is to evaluate the Utah Department of Transportation’s (UDOT’s) ATISs. This study will assess the effectiveness of four ATIS systems in Utah: Variable Message Signs (VMS), Highway Advisory Radio (HAR), 511 toll-free phone service, and CommuterLink online service. This study’s research objectives are to determine the level of public awareness of ATIS in Utah, assess usefulness of UDOT’s ATIS, investigate the effect of ATIS on driving habits, and determine the influence of demographic factors on ATIS use. The public surveys will be conducted randomly in the Salt Lake Valley. Two-hundred licensed drivers will be interviewed personally. The responses will be statistically analyzed. Additionally, respondents will be asked open-ended questions to obtain their views on and suggestions for ATIS.
