Evaluation of Effectiveness of Automated Work Zone Information Systems

With the advancement of the intelligent transportation system technologies, some automated work zone information systems (AWISs) have been developed and deployed in the field. Their purpose is to provide useful real-time traffic information to motorists as they approach or pass through a work zone. Several studies have been conducted to evaluate AWISs, and most of those studies paid attention to the evaluation of system functionality and reliability. This paper focuses on the evaluation of the effectiveness of the computerized highway information processing system deployed in Southern California, pertaining to the aspects of safety and diversion effects, as well as travelers’ acceptance. Evaluation results showed most driver survey respondents liked the system, which was found to be effective in diverting traffic and promoting smoother traffic flow during congested periods.
