Evaluation of Post Mounted Delineators and Curve Warning Message Markings

The purpose of this study is to evaluate post-mounted delineators and curve warning message markings by deploying them on a sample of VDOT roads based on a statistically robust sampling plan. This will be accomplished in three phases. This project will conduct the first phase of this study. Tasks in the first phase include conducting a literature review and outreach to determine best design and maintenance practices, identifying the specifications for modification, and designing a sampling plan. A second phase will deploy and monitor the two treatments in the field following the plan developed in the Phase 1 study. A phase 3 study would conduct the before and after crash analysis, crash modification factor (CMF) development and benefit-cost analysis. This study fits well into current VDOT safety programs, policies, and initiatives for reducing roadway departure crashes (RDCs). Positive research results would provide additional countermeasures statewide for RDCs that will benefit the ongoing systemic safety program. VDOT will benefit from the development of CMFs specific to Virginia by determining the expected return on investment in phase 3. This Phase 1 study is critical in that it provides the foundation for development of credible CMFs.
