Abstract
With the advent of Intelligent Transport Systems (ITS), especially over the last decade, considerable researches have been conducted on drivers' responses to Advanced Traveler Information System (ATIS). Some of the results are being used in an operational level. However, still much additional research is needed to identify optimal strategies for providing traffic information to drivers. This study analyzes results of a mailed survey of frequent freeway users in Wisconsin to determine driver response to Variable Message Signs (VMS). Respondents to the survey are quite familiar with VMS and have generally positive attitudes towards VMS and its effectiveness. Factors that perceived usefulness of VMS information have been identified. Regression analysis is used to quantify the relationship between the reliability of VMS information and the number of route adjustments. Other human factor problems such as readability and visibility of VMS have also been found along with some prospective recommendations. Some limitations and future research agenda have also been discussed.
