• Abstract:
  Smart work zones utilize technologies and strategies to enhance transportation safety, mobility, traveler satisfaction, and even construction/maintenance productivity through and around work zones. To date, there have been both positive and negative experiences with the technology. The objectives of this study were to determine why some smart work zone deployments in Texas have been more effective than others, and to determine how TxDOT’s current processes for incorporating smart work zones into projects should be modified to improve how smart work zones are selected, procured, implemented, and maintained during construction. Researchers interviewed TxDOT, contractor, and SWZ vendor staff, conducted operational and safety analyses of SWZ systems at a sample of projects, and reviewed contract management documentation related to SWZ deployments. Based on the information gathered, researchers identified potential improvements to TxDOT’s project development and construction management workflows, bid specifications, and supporting resources to increase the likelihood of successful smart work zones on future projects.
