A lot of the discussion around transit-oriented development in norcal is around putting higher density around existing train stations, but BART and Caltrain are already at capacity during rush hour. I feel like San Francisco and Mountain View would get far bigger bang for their buck if SFMTA and the Planning Commission could coordinate to build bus-centric high-density transit developments around the existing freeway off-ramps. Just add another pedestrian/bike/transit-friendly bus loop connected to the freeway (like the Salesforce Transit Center, although maybe not on stilts). Facebook, Google, Apple, etc already pay for operating the buses, and would add more if the buses achieve high enough utilization.
