Studies to Develop Guidelines for Work Zone Barrier Use on Freeways

Author/Presenter: Ullman, Gerald L.; Rista, Emira
Abstract:

This report describes research efforts to:

  • Investigate the issues affecting temporary barrier deployment in work zones with constrained cross
    sections.
  • Identify and evaluate available options to potentially address those issues.
  • Develop improved guidelines regarding barrier deployment on Texas freeways.

Efforts included:

  • A review of literature relevant to the deployment and use of barriers in work zones and Texas work zone
    crashes to better understand any direct or indirect influence of barrier presence.
  • Surveys of key stakeholders to identify the state of the practice in barrier use and road user perceived
    difficulties in traveling through various types of work zones with barriers.
  • Field evaluations of multiple barrier deployments on freeway work zones in constrained cross sections to
    identify deployment issues.
  • Development of analytical approaches to help guide work zone designers and other project staff when
    making work zone barrier deployment decisions.

A stand-alone set of recommended guidelines was prepared and is included as the appendix to the report.
