Project

“Link21” is a megaregional transit improvement program focused on connecting the transit systems in the Northern California megaregion, consisting of the 21 counties between Monterey, San Francisco, Sacramento and the northern San Joaquin Valley. At the core of the Link21 program is a new transbay rail crossing for BART and regional rail including the Capitol Corridor, the San Joaquin Regional Rail, and Caltrain.

Our Work

ETG provided travel demand modeling support for the market analysis tasks of the New Transbay Rail Crossing (NTRC) project. To provide the framework for market analysis of the Northern California megaregion, ETG created a megaregion network and trip tables by combining the model networks and trip tables from the Metropolitan Transportation Commission (MTC), Sacramento Area Council of Governments (SACOG), San Joaquin Council of Governments (SJCOG), Stanislaus Council of Governments (StanCOG) , Merced County Association of Governments (MCAG), and Association of Monterey Bay Area Governments (AMBAG) travel demand models.

ETG implemented an innovative Emergent Network Modeling Framework approach using the travel demand models to identify the corridors with the highest transit demand in the region.
