Criteria and Guidelines for Three-Lane Road Design and Operation Status: CompleteReport Date: 03/13/2023 Summary: This project seeks to (1) codify existing guidance on three-lane road conversions through a review of existing research and practice and (2) conduct research needed to close identified, important, gaps in existing knowledge. The final products will be HCM-type model relating traffic demand and geometric/control design features to predicted LOS-based performance and HSM-type model relating the same to predicted crash experience.
