Design Optimal and Effective Queue End Detection and Notification: Development of a Low-Cost Work Zone Queue Warning Systems in Iowa

On average, 105 fatal front-to-rear crashes occur in American work zones each year, representing nearly 20% of all work zone fatalities. Most often, the incidents are the result of a high-speed vehicle colliding with a vehicle stopped or slowed by work zone congestion. A number of intelligent transportation system (ITS) systems have been developed to provide back-of-queue warning, but historically the cost and complexity of these systems has limited their use. Even when back-of-queue warning is deployed, the spatial coverage is sometimes inadequate due to the highly variable queue lengths that are typical for most sites. We propose to field-test a low cost system designed to reduce costs and simplify deployment. If successful, this system could allow back-of-queue warning to be installed wherever queuing is anticipated, even for short-term projects. Its modular design will allow the queue warning to be extended as far upstream as necessary to provide ample driver notification in high, medium, and low demand situations.
