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.
