Determining the Suitability of Freeway Corridors for Managed Lanes Deployment

Previous research and deployment efforts showcase the potential benefits of managed lane strategies toward increasing the utilization and efficiency of transportation facilities, and reducing congestion and related impacts. However, criteria for determining the suitability of a specific highway corridor for deployment of managed lane strategies are less well established. This paper reports on a study that incorporated best practices to develop a standardized screening and evaluation methodology leading to the identification of promising corridors for managed lanes deployment. Best-suited managed lane strategies for the selected corridors are also identified. The methodology is then used to screen potential corridors in Alabama’s largest urban areas based on the proposed assessment criteria and desired outcomes. The findings are expected to provide valuable guidance to transportation professionals and decision makers towards selecting appropriate corridors for implementation of managed lanes based on need, feasibility, and potential return for the investment.
