About the research
Improving the accuracy of work zone data is a multi-layered problem of which a number of agencies have been working to address over the last several years. Connected temporary traffic control devices (cTTCDs) such as smart arrow boards and other connected devices have the capabilities to improve the accuracy of work zone data without a contractor or agency employee having to manually enter the information. As the number and types of devices have increased, little guidance has been developed on how to use information from these devices within an agency. This project will document and evaluate how cTTCDs can be used by an agency for both historical and real-time applications. The approach starts with an agency state-of-the-practice review to summarize how the data are currently being utilized. A number of integration methods will be evaluated with the goal of highlighting noteworthy practices and documenting agency considerations when integrating the data into their systems.
