In Phoenix, Arizona, an evaluation of website traveler information found that 16 percent of surveyed respondents thought the web site information was useful.
Evaluation results for ATIS included in the report present an assessment of customer satisfaction with the publicly operated Trailmaster web site and the Traffic Check cable TV traffic information service. Both the web site and television channel provided information on travel conditions on Phoenix area roadways by integrating data from the freeway management system and the Arizona Department of Transportation (ADOT) Roadway Closure and Restriction System.
Analysis of web site usage statistics indicated that the number of visits to the traveler information web site increased steadily during the evaluation period at a rate of 50 percent per year; evaluators expected this trend to continue. Overall, usage levels for the Phoenix web site were significantly lower than those experienced in Seattle, where traffic congestion is a more significant problem (as reported in the Seattle MMDI report). Two focus group studies revealed Phoenix area travelers felt that congestion levels were not high enough to warrant frequent use of the site. Users did find the site helpful in assessing delays due to construction. Participants felt that the addition of congestion information for arterial roadways would make the site more useful. Overall, 16 percent of respondents rated the Internet service as "Useful."
