    About this Project
    Brief Project Description & Background
    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 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.
    Research Objective
    The main goal of the proposed research is to develop a procedure for evaluating the effectiveness of work zone ITS for specific work zone projects. A general procedure for agency use in evaluating the effectiveness of each work zone ITS project will be outlined. Using the developed procedure, the research team will evaluate the effectiveness of one work zone ITS project in terms of traffic diversion rate, crash rate, queue, delay, and speed reduction. The research results will be disseminated through webinars to a broader audience interested in deploying ITS in work zones
    Potential Benefits
    Evaluating the benefits of ITS deployments is relevant to three of the five USDOT and MATC's thematic topics: enhancing safety, economic competitiveness, environmental sustainability. Work zones can have a negative impact on safety of traffic and workers, efficiency of traffic flow, and air pollution. Smart work zone systems aim to minimize these negative impacts of work zones thereby increasing the safety and efficiency of traffic.

This project aims to develop a framework for evaluating the effectiveness of SWZS and illustrate it on an actual work zone deployment in Missouri.
