Description
| Abstract: | This report describes research efforts to: 1. Investigate the issues affecting temporary barrier deployment in work zones with constrained cross sections. 2. Identify and evaluate available options to potentially address those issues. 3. Develop improved guidelines regarding barrier deployment on Texas freeways. Efforts included: 1. 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. 2. 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. 3. Field evaluations of multiple barrier deployments on freeway work zones in constrained cross sections to identify deployment issues. 4. 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. |
