NCHRP Synthesis 20-05/Topic 53-10 [New]

Practices for Contrast Pavement Markings
[ NCHRP 20-05 (Synthesis of Information Related to Highway Practices) ]

Funds: $45,000
Authorization to Begin Work: 4/30/2021 -- estimated

Preliminary Scope

Contrast pavement markings are currently being used by several state departments of transportation (DOTs) and will likely be implemented by others in the future. There are several different contrast pavement marking designs currently utilized, but knowledge gaps exist regarding prac-tices for varied roadways, drivers, or autonomous vehicle technology. Furthermore, the safety benefits of contrast pavement marking designs have not been identified. However, benefits of contrast pavement markings may include crash reductions stemming from lane departures, reduced life-cycle costs related to durability, and identification of lanes based on strip location by autonomous vehicle technologies.

The objective of this synthesis is to document the current practice of contrast pavement markings by state DOTs.

Information to be gathered includes (but is not limited to):
• Use of contrast pavement markings;
• Use of contrast pavement marking design configurations;
• Documented benefits regarding contrast pavement markings; and
• Design factors, including autonomous vehicle sensing capabilities.

Information will be collected through a literature review, a survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
