Since the onset of the COVID-19 pandemic, one question we frequently hear from our clients is: How has local travel behavior changed? To help provide answers, we embarked on a self-funded research effort, collecting pre-COVID and 2022/2023 traffic data at residential, retail, and mixed-use sites across California. We also conducted multi-day surveys at large office parks, one of the land uses most affected by the pandemic.
Our findings reveal significant shifts in travel patterns, especially at office buildings, where trip generation rates have dropped well below the rates set by ITE’s 2021 Trip Generation Manual, which consists entirely of pre-COVID data. These insights could have important implications for transportation planning, from travel demand models to infrastructure forecasting and fee programs.
For a deeper look at the data and what it means for future planning, check out our full white paper. Questions? Feel free to reach out to the report’s primary author, John Gard, PE, RSP1.

VMT under CEQA continues to evolve as agencies, practitioners, and decision makers work through analysis methods, mitigation feasibility, and defensible evidence. Our new Q&A resource offers practical answers on vehicle miles traveled, SB 743, mitigation program design, implementation, administration, and legal and strategic considerations.
Demand Management Is Injury Prevention
New research shows that reducing driving exposure may be one of the most powerful safety strategies available. The findings connect VMT, mode share, and travel time to fatality rates, reframing demand management as injury prevention.
Announcing Safety Multipliers
What do San Francisco’s Van Ness BRT, New York’s congestion pricing, and Arlington’s intersection program have in common? Each pulls all three Safe System levers at once. We call that pattern a safety multiplier.
