Stacking Benefits: The Role of Land Conservation in VMT Mitigation

 

What six California case studies reveal about how conservation might reduce driving, and when it might not.
February 6, 2026 • 1 minute read
As communities across California look for ways to reduce driving while protecting open space, land conservation is increasingly part of the conversation. Our latest white paper explores this connection using six real-world California case studies.

This work builds on our previous collaboration with The Nature Conservancy that explored how vehicle miles traveled (VMT) mitigation programs can help protect natural resources and wildlife in Western Riverside County.

This latest phase takes the analysis statewide, looking at how real-world factors like development pressure, nearby housing capacity, and the risk of “leapfrog” development affect the potential for VMT mitigation in different contexts.

The goal was to understand whether protecting and conserving land that might otherwise be developed can reduce driving, measure how much it reduces driving, and identify when this approach can count as a defensible mitigation strategy under CEQA and Senate Bill 743.

What we found was nuanced. Land conservation can help avoid or reduce VMT over time, but not always. There must be a realistic chance that the conserved land would have been developed, and that the development that would have occurred there could instead be built in a lower-VMT area. There’s still a lot to learn about how statewide policies promoting infill development will play out, and what that means for using land conservation as a VMT mitigation strategy.

Read the full white paper to learn where this approach works best, what questions to ask early, and how today’s land use decisions can shape travel patterns for years to come.

Understanding AI’s Role in Transportation Safety

AI is giving transportation safety practitioners new ways to analyze data, detect near misses, and respond to risk before crashes happen. Real-world examples from Bellevue, WA and San Bernardino, CA show where AI-supported technology is delivering value—and where human judgment remains essential for turning data into responsible safety decisions.

New NCHRP Toolkit Helps Agencies Build Safety Into Everyday Decisions

Making streets safer takes more than individual projects. Our new Safe System approach toolkit, developed through NCHRP Research Report 1181, helps agencies integrate safety into policies, budgets, design standards, and land use decisions. Explore practical tools, real-world case studies, and new IIHS Safe System success stories that show how agencies are turning safety into standard practice.
