Improving the Utilization and Effectiveness of Smart Work Zone Deployments

Smart work zones (SWZs) have been shown to have traffic safety and mobility benefits when and where they are truly needed, properly designed, implemented, and maintained. The use of SWZ deployments has become more common on projects across the state. As defined in TxDOT guidance: Smart Work Zone Guidelines dated October 2018, these technologies typically produce data and/or images that are processed to become actionable information. Although guidance exists to assist with designing and implementing these systems, research is needed to understand why some deployments have been more effective than others. Research is also needed to determine how TxDOT’s SWZ selection, procurement, implementation, and maintenance processes should be improved. To achieve these research objectives. The work to be performed with this project includes: 1) Identifying a sample of projects across the state where SWZs have been deployed. 2) Reviewing any information available on best practices from other state departments of transportation. 3) Interviewing TxDOT, contractor, and SWZ vendor staff to determine the decision-making processes of those SWZ deployments, challenges encountered, and perceptions about their effectiveness. 4) Where data is available, conducting operational and safety analyses to determine actual effects of the systems. 5) Reviewing contract management documentation related to those SWZ deployments. 6) Identifying potential improvements to TxDOT’s project development and construction management workflows, bid specifications, and methods of payment to increase likelihood of successful smart work zones on future projects.
