Title:

Final Report: Model Deployment of a Regional, Multi-Modal 511 Traveler Information System

Abstract:

This document presents the findings of the national evaluation of the 511 telephone traveler information system "Model Deployment" in Arizona. The national evaluation documented costs and lessons learned, measured the accomplishment of the implementers' hypothesized project impacts, and assessed the extent to which the Arizona 511 project satisfied U.S. DOT objectives for the Model Deployment, including providing traveler information on road weather conditions. Many miles of Interstate, State, and US Highway routes in Arizona are located in high-altitude areas that receive considerable snow and ice, thus making winter-weather traveler information important. Among the perceived benefits, having the ability to access current road and weather information was cited most frequently by both repeat (33 percent) and first-time users (28 percent). Snow events appear to be closely related to 511 usage. In fact, the snow events produced the highest volumes of calls to 511.
