Effectiveness of Work Zone Intelligent Transportation Systems

In the last decade, Intelligent Transportation System (ITS) technologies have been deployed in work zones by state departments of transportation (DOTs) to improve traffic operations and safety. Also known as Smart Work Zone Systems (SWZS) these deployments provide real-time information to travelers, monitor traffic conditions, and manage incidents. Although, there have been numerous ITS deployments in work zones to date, the evaluation of the effectiveness of these deployments has not been well documented. To justify the continuous development and implementation of work zone ITS, there is a need to determine the ITS effectiveness for specific work zone projects in terms of traffic diversion rate, delay, crash rate, queue, and speed management. This project aims to develop a framework for evaluating the effectiveness of SWZS and illustrate it on an actual work zone deployment in Missouri. The Mid-America Transportation Center (MATC) portion of the effort is focused on technology transfer activities in terms of disseminating the results of the developed framework to a broader audience.
