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.
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.
As climate risk reshapes transportation planning, public agencies need strategies that connect resilience with everyday investment decisions. Marissa Aho, FAICP, brings decades of experience helping cities and regions turn climate risk into practical, fundable actions. Learn how her leadership expands our climate adaptation and resilience practice and strengthens the support we provide to communities.
Join us in congratulating the 167 team members who earned promotions for their outstanding contributions this year.
How much can planning decisions actually reduce driving? Our latest research introduces a statistical model that links built environment choices—such as density, transit service, walkability, and land use mix—to vehicle miles traveled (VMT). The findings give planners and policymakers practical, evidence-based tools to evaluate scenarios, understand tradeoffs, and make more informed transportation and land use decisions.
