Los Angeles’ Vision Zero Technical Analysis: A Data-Driven Effort to Eliminate Traffic Fatalities
In August 2015, Los Angeles Mayor Eric Garcetti issued Executive Directive 10, Vision Zero Initiative, establishing a goal of zero traffic deaths in Los Angeles by 2025. In response to this directive, the Los Angeles Department of Transportation (LADOT) completed an in-depth, data-driven process to build the foundation of a city-wide Vision Zero initiative. This study documents the innovations developed to analyze collision data, pair countermeasures to specific data-driven trends, and prioritize high-collision locations. A team of planners, engineers, statisticians, and data analysts worked together to create a process grounded in national best practices and tailored to meet the specific needs of LADOT. This study can be used as a guide to help cities develop their own robust data-driven Vision Zero process, to develop an understanding of collision patterns across the city, pair countermeasures in locations where the greatest collision reduction could be obtained, and prioritize the most critical intersections. More immediately, this study positions LADOT to develop an Action Plan, including prioritized locations and project descriptions for the first several years of Vision Zero infrastructure investment and any related projects through LADOT’s normal course of work.
