Caltrain/HSR Blended Grade Crossing and Traffic Analysis

Key Considerations:

The study broadly examines how certain prototypical modernized Caltrain and Blended System train schedules affect gate  downtime and local traffic conditions at the system's at-grade crossings.

Model results have limited application because the results can vary substantially based on model inputs, which include but are not limited to:

Schedule. No schedule has been determined for either a modernized Caltrain or a blended system.

Passing tracks/grade separations.  Decisions have not been made about any possible passing track or grade separation locations.

Increased train service does not ensure an associated increase in gate downtime.     

A reduction or increase in gate downtime has modest impact on local traffic circulation compared to the impact of  regional growth projections. These growth projections predict that traffic circulation will become substantially worse throughout the region regardless of the gate-downtime reduction or increase associated with the operation of modernized Caltrain or blended system train service. Compared to these projections, the Caltrain Modernization Program and the blended system would only marginally impact future traffic conditions. 

This is the first of several planning efforts that will be needed to inform the blended system planning process and ultimately define the blended service schedule, grade crossing improvements, and local traffic circulation strategies. A more thorough review of the gate-downtime and traffic circulation impacts associated with the Caltrain Modernization Program will be included in the updated Caltrain Electrification Project EIR/EIS.
