Criteria and Guidelines for Three-Lane Road Design and Operation

Status:  Active
Project Start Date:  09/28/2018

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.

Final Deliverables:
