Concurrent Flow Lanes – Phase 1

Project 20

In the first phase of this multi-phase research effort, interviews were conducted with project managers of existing and proposed HOT lane facilities, modelers and other domain experts, and related reports and literature were reviewed. This effort culminated in a comprehensive understanding of the state-of-the-practice and state-of-the-art in modeling of nonbarrier separated HOT lane and other concurrent flow lane operations.

Specific details related to the models employed, and analytical tools used, around the country to evaluate the impact of proposed HOT lanes on traffic operations and potential revenue were revealed and information pertaining to lane configurations, tolling strategies, high occupancy vehicle (HOV) restrictions, types of separation, how weaving is addressed, and design alternatives for ingress and egress between the HOT and general purpose lanes were documented.

The research effort also addressed alternate merging solutions reported by other states that have been modeled, analyzed and/or implemented with potential applicability to freeways in the Washington, D.C. region. Initial investigation into the specific steps required to calibrate and validate the simulation model was conducted and potential data sources for calibrating and validating developed models were identified.
