California Statewide Freight Forecasting and Travel Demand Modeling (CSF2TDM)
The California Department of Transportation (Caltrans) has developed the California Statewide Freight Forecasting and Travel Demand Model (CSF2TDM) to provide Caltrans and other transportation partners with an advanced multi-modal tour/activity-based travel demand model that forecasts short and long distance travel by California residents as well as all commercial vehicle travel throughout the state. CSF2TDM is fully integrated to capture passenger and freight trips together.
The CSF2TDM helps Caltrans transportation related policies that best meet mobility goals as well as evaluate the impacts of freight movement on traffic congestion, mobility, air quality public health and equity. Partner agencies utilize this model to meet the air quality requirements set forth under AB 32, SB 375 and SB 391. The CSF2TDM is also a key tool for emissions and greenhouse gas (GHG) analysis.
How does it work?
The CSF2TDM utilizes Citilabs Cube modeling software and has been updated to provide 2020, 2030, 2040, and 2050 forecast years. It has a 2015 base year and utilizes the 2012 California Household Travel Survey (CHTS) data, census data and updated population and jobs forecasts up to 2015. Model updates are expected on a 5 year cycle, with every other update incorporating new travel behavior and census data beyond the updated population, school enrollment and employment forecasts and updated planned projects from the MPOs, RTPAs and Caltrans
Products
The CSF2TDM helps Caltrans plan for and evaluate the impacts of infrastructure enhancements on the economy, environment, traffic congestion, mobility, air quality, fuel consumption, GHG emissions, public health, climate change and equity.
