Abstract:The implementation of minimum levels of pavement marking retroreflectivity may lead some agencies to change the types of pavement marking materials used on roads and/or may result in a changed service life for the marking materials they currently used. To assess the economic impacts, researchers developed a spreadsheet-based analysis tool that calculates the costs associated with implementing minimum retroreflectivity levels. The spreadsheet considers the impacts of retroreflectivity levels, choice of materials, cost of materials, roadway types, and roadway mileage. The researchers used the analysis tool to assess several different scenarios that considered retroreflectivity level (low, base, and high), marking cost (low, base, and high), and material selection (water-based and selected durable materials). Using the mid-range of assumed pavement marking costs, the analyses described in this report show that the economic impacts of implementing minimum levels of pavement marking retroreflectivity range from $0 to almost $150 million per year, depending on the assumptions used in the analysis. In some cases, the analyses show that potential cost savings can be realized when status quo practices are compared to alternative practices that include the use of more durable pavement marking materials.
