Project at a Glance

Title: A Data Science Framework to Measure Vehicle Miles Traveled by Mode and Purpose

Principal Investigator / Author(s): Gonzalez, Marta

Contractor: UC Berkeley

Contract Number: 20RD005


Research Program Area: Climate Change

Topic Areas: Greenhouse Gas Control, Greenhouse Gas Emissions, Sustainable Communities


Research Summary:

California has adopted aggressive policies to reduce greenhouse gas emissions to 40 percent below 1990 levels by 2030. Based on current estimates, metro areas in the state are falling short of the vehicle miles traveled (VMT) reduction goals stipulated by Senate Bill 375. The goal of this contract is to develop techniques to integrate and analyze existing data, including big data (GPS- and cellphone-based travel data), to create a statewide picture of VMT fluxes over time and extract behavioral choices to generate estimates of urban mobility before, during, and after the COVID-19 pandemic. Results from before COVID-19 will improve our understanding of regional travel behavior and inform VMT reduction strategies. Results from the after COVID-19 will inform policies that could equitably maintain VMT-related changes after the pandemic is contained. Overall, results from this work will also improve CARB's understanding of regional travel behavior and guide the implementation of programs to achieve the VMT reduction goals stipulated by SB 375
