Abstract

This paper presents a human factors study on the cause and effect of slow-downs due to messages displayed on dynamic message signs (DMS). DMSs are employed to provide drivers with timely information and traffic advices but the slow-downs caused by them could pose a threat to driving safety. To determine the causes of slow-downs, traffic data collected by a network of mobility technology units (MTUs) were analyzed and results obtained from a questionnaire survey were assessed. Findings obtained from the study recognized major causes of slow downs and identified effective DMS displays that could help ease the slow down effect.
