Deterioration of Green Conflict Paint for Bicycle Facilities

Many cities in the Pacific Northwest are expanding their bicycle network to improve mobility. One recent innovation is the use of “green conflict” paint to improve bike lane visibility. The goal of is this project is to evaluate the performance of green conflict paint under simulated deterioration and different operating conditions, including rain and snow. The relevant PacTrans theme is Improved Reliability across Modes: decision support tools for winter road maintenance and performance under extreme conditions. The research team will test different green paint products (e.g., water-based and thermoplastic) under varying levels of simulated traffic and snow removal agitation. The team will document at least seven measures of effectiveness (MOEs) including friction, texture, color, luminance, percent loss, and retroflectivity. The team will use a three-wheel simulator under different loadings to simulate varying levels of traffic. The MOEs will be assessed under simulated weather conditions wet, dry, and snowy (low temperature slush). Friction will be analyzed for solid design and dashes. Additionally, the team will inspect the installation of green conflict paint in the field. The City of Moscow has scheduled installation at eight intersections along a one-mile section of a minor arterial.
