San Joaquin Valley Model Improvements

San Joaquin Valley Model Improvements – Phase 1 (MIP1)
In April 2010, the 8 San Joaquin Valley MPOs applied for and was awarded $2,500,000 of Proposition 84 funds by the Strategic Growth Council (SGC) for Valley wide model improvements. The modeling improvements were to update each Valley MPO model to be more sensitive to smart growth in order to meet the requirements of SB 375.

The Valley modeling improvements were completed in 2012 and used in the development of each Valley MPOs Sustainable Communities Strategies (SCS) in compliance with SB 375. This project is known as the Valley Model Improvement Plan (MIP)

San Joaquin Valley Model Improvements Phase 2 (MIP2)
Recently the Valley MPOs were awarded and additional Proposition 84 Round 2 grant for additional model improvements to the 8 Valley MPO traffic models. In January 2014 and RFP was issued for the additional improvements to the valley models.

The RFP calls for the acquisition of new data sources for use in the valley models including:

  • Aggregate cell phone data for county to county O-D flows, San Joaquin Valley and Statewide
  • Traffic speed data from GPS equipped vehicles
  • 2010 Census data and American Community Survey (ACS) data for demographics and commute data
  • 2010-2012 California Household Travel Survey results – (recently available)
  • Recalibration and revalidation of each model

This new data will help us have:

  • Better estimates and forecasts of trips entering and leaving our counties and the valley and state
  • Better understanding of the trip distribution within our counties/state
  • Better information on vehicle speeds – critical for air quality analysis

Green House Gas reduction analysis relies heavily on our ability to adequately model interregional trips and speeds. This data will greatly improve our ability to model for SB 375 and Sustainable Communities Strategy.
