The San Francisco-Oakland Bay Bridge (SFOBB) in California is one of the most heavily traveled corridors in the United States. The purpose of this project is to implement a new Metering Lights system at this bridge that accounts for the bridge’s capacity and alignment, increases toll plaza throughput, adapts to traffic incidents, reduces queuing at the toll plaza, and accommodates differential metering rates for different types of users (including buses, high-occupancy vehicles (HOV), FasTrak electronic payment users, and cash users).
TJKM, as a member of a project team, is leading the development of micro-simulation models to help demonstrate and evaluate various metering algorithms, with the goal of selecting the best metering algorithm for the new Metering Lights system for implementation at this bridge where there are 16 lanes at the metering lights before merging to the five-lane bridge. The simulation task includes data collection and analysis, simulation model development, model calibration, metering algorithm simulation, scenario testing, output analysis, and draft and final reports. In addition, TJKM is also assisting the project team in developing the metering algorithms, designing the metering system software, coordinating with the Civil Contractor and System Integrator, and participating in system testing.
