From LOS to VMT: Repurposing Impact Fee Programs Since Adoption of SB 743

Research Product Type
White Paper
This white paper assesses how cities are modifying transportation impact fees in response to Senate Bill (SB) 743, adopted in 2013 to orient environmental review of transportation impacts of development projects and plans in California to support sustainable development.

Future Passenger Travel Demand in the United States

  • Principal Investigator Giovanni Circella, Ph.D.
  • University of California, Davis
This white paper discusses a potential "Vehicle Miles Traveled (VMT) Peak" for the 21st century. It presents a research agenda designed to clarify the reasons for the current VMT peak and to assess the implications for future passenger travel demand in the U.S.

Household Vehicle Choice in California: Behavior and Impacts

Research Product Type
Policy Brief
An increasing diversity of vehicle types, paired with a growing demand for PEVs, has major implications for vehicle miles traveled (VMT), air pollution, and emissions. To better understand what is likely to happen, researchers predict household vehicle preference and VMT by vehicle body and fuel type.

Impacts of Remote/Hybrid Work and Remote Services on Activity and Transportation Patterns

  • Principal Investigator Giovanni Circella, Ph.D.
  • University of California, Davis
This project will greatly improve the understanding of the impacts of remote/hybrid work and other remote services and inform State and planning agencies by shedding light on the complex ways remote activities affect short‐term daily routines (e.g., telecommuting vs. commuting trips, travel mode choice, and spatial/ temporal trip distributions) and long‐term choices (vehicle choice, residential location and real estate development), and will help understand the impacts on vehicle miles traveled (VMT) and transportation‐based greenhouse gas (GHG) emission impacts.

Increasing Highway Capacity Induces More Auto Travel

Research Product Type
Policy Brief
Researchers at the University of California, Davis reviewed the empirical research on induced travel to understand the likely effects of adding roadway capacity in a variety of contexts.

Induced Travel Calculator

Research Product Type
Calculator
This calculator looks at how the addition of high-occupancy vehicle lane (HOV) miles contributes to the addition of vehicle miles traveled (VMT).
