The ENTERPRISE Pooled Fund Program initiated a project to document the resources available as well as uses and benefits regarding the following Intelligent Work Zone (IWZ) technologies: queue warning systems, dynamic merge systems, alternate routes and variable speed limits in work zones. A detailed literature search was conducted to summarize work zone materials available related to the four work zone technologies. In addition, intelligent work zone representatives from transportation agencies were contacted to provide details on recent related deployments and provide input to the project.
The purpose of the final report is to understand the current status of work on IWZ activities by combining the resources gathered through a literature search with the information collected from the transportation agencies on recent deployments. Also included is a summary of the four IWZ technologies including examples of successes, any guidance possible when technologies are most effective, and the configurations that demonstrated the best results. Seperate documents were then created from the final report highlighting the summary of uses and benefits for each IWZ technology as a quick reference for the specific technology of interest.
The Synthesis of Intelligent Work Zone Practices project was presented at the following:
- ITS Minnesota Fall Forum (October 2014)
- ENTERPRISE Project Webinar (April 2014)
