Pasadena, California is using temporary materials like paint and bollards to test car-free corridors designed to protect pedestrians and cyclists, part of a $104,000 federal safety grant aimed at reversing a deadly national trend.

The project will create trial greenways—streets where cars are banned or heavily restricted—to see which designs actually reduce crashes before the city commits to permanent infrastructure. Data from these quick-build demonstrations will shape a long-term plan for safer routes across Pasadena's 23 square miles.

The timing reflects a crisis: pedestrian deaths nationwide jumped 77% between 2010 and 2021, driven by larger vehicles, distracted driving, and streets built for speed over safety. California accounts for roughly one in six U.S. pedestrian deaths. Pasadena adopted a Vision Zero policy in 2016 pledging to eliminate traffic fatalities, but deaths rose in the years after, a pattern seen across California cities where political commitments haven't translated to street redesigns.

The temporary approach addresses a political problem as much as a safety one. Permanent bike lanes and traffic-calming measures often face fierce opposition from residents worried about losing parking or slowing car traffic. Quick-build projects let cities test changes in weeks, gather crash and usage data, and adjust based on evidence rather than assumptions. New York and San Francisco pioneered the model over the past decade.

The grant comes from Safe Streets and Roads for All, a $6 billion federal program created in 2021 specifically to fund Vision Zero projects. Pasadena's $104,000 covers materials, data collection, and community engagement for the demonstration phase.

The city hasn't announced which streets will be included or when construction starts. If the data shows the greenways work, Pasadena will use the results to pursue larger grants for permanent infrastructure.
