Data and Reports

Fatalities from traffic collisions, particularly those involving pedestrians and bicyclists, are a significant and growing public crisis in Los Angeles County. Over the past decade (2015-2024), fatalities from traffic collisions in unincorporated communities of LA have been and continue to be high with an average of 88 deaths per year. During the COVID-19 pandemic, traffic fatalities jumped dramatically in these communities consistent with what occurred nationwide (2020 Fatality Data Show Increased Traffic Fatalities During Pandemic | NHTSA).

A study by the AAA Foundation for Traffic Safety found speeding, not using seatbelts, and impaired driving to be main contributors to the increase compared to pre-pandemic times (The Pandemic’s Tenacious Grip on Traffic Safety – AAA Newsroom).

Characteristics of Fatalities from Traffic Collisions in Unincorporated Communities of Los Angeles in the past decade (2015-2024):

Line chart showing traffic collision fatalities in unincorporated Los Angeles from 2015 to 2024 by road user type, including drivers, passengers, pedestrians, bicyclists, and total fatalities. Total fatalities peaked in 2021 and 2022, while pedestrian fatalities remained consistently high throughout the period.

Through analyses of traffic collision data from UC Berkeley SafeTrec’s Transportation Injury Mapping System (TIMS), the PLACE Program identified pedestrian safety and illegal driving behaviors as priority areas for Public Health to address in unincorporated communities. Of the illegal driving behaviors, we highlight the impact of hit-and-runs, speeding, and Driving under the Influence (DUI) on traffic fatalities.

Hit-and-Runs

Nationally, one in four pedestrian deaths is the result of a hit-and run crash (Pedestrian Traffic Fatalities by State: 2024 Preliminary Data, Governors Highway Safety Association). In unincorporated LA, of the reported collisions, hit-and-run crashes have been responsible for 30% of pedestrians killed between 2015-2024. This proportion has been as high as nearly half of the pedestrian fatalities in 2016 and 40% in 2018, 2022, and 2023. Hit-and-Runs were also a major contributor of fatalities among bicyclists. Hit-and-run crashes can multiply the severity of injuries or lead to fatality by delaying or denying post-crash medical care, a critical element of the Safe System Approach.
