Pedestrian and Bicycle Crash Data by County

Pedestrian and Bicycle Safety Trends

To support California counties with Pedestrian/Bicycle Master Plans, we have included county-specific pedestrian and bicycle crash data from 2020 - 2024 (SWITRS 2020 - 2024/Provisional 2024 update as of March 11th, 2025) below. 

The following time series, interactive maps and accompanying tables aim to give a brief overview of pedestrian and bicycle crash data on a state and county wide level across California. All visuals and data from tables can be easily downloaded from this page, simply click the icon at the top right of each visual and select the format of your choice. 

For city-specific breakdowns or any other queries related to Pedestrian and Bicycle crashes, please use SafeTREC's TIMS ATP Maps & Summary Data Tool(link is external)(link is external). This tool allows users to create multiple crash maps to find pedestrian and bicycle crash hot spots and generates data summaries within specified project and/or community limits.

Pedestrian & Bicyclist Fatalities Time Series 

Pedestrian & Bicylist Fatalities Over Time Series Description

The Time series details pedestrian and bicyclist fatalities from 2015 to 2024. Fatality trends for pedestrians rose from 2014 to 2022. For bicycle fatalities they rose from 2014 to 2018, followed by a dip from 2019-2021 and a sharp spike in 2022. Please note that 2023 and 2024 data are provisional and therefore should be interpreted with caution.

Pedestrian and Bicyclists Fatalities and Serious Injuries (FSI) Percentage Change

Pedestrian and Bicylist FSI Percentage Change Maps Description

Two Choropleth maps of California counties detailing the percentage change of pedestrian and bicylist FSI from the 3 year average of 2014 to 2016 to the 3 year average of 2021 to 2023. Counties with a positive percentage change, indicating that the number of pedestrian FSI increased in 2021-2023 period versus the 2014-2016 one, are indicated in dark orange. No change or a descrease in crashes over those two time periods is indicated in light orange. For bicyclists, a positive percentage change in the number of bicyclists FSI is indicated in dark blue while light blue indicates a decrease or no change. 

For more information including the 3 year FSI averages by county for pedestrians and bicyclists, please see the summary tables below.

Note: For some counties, as indicated in white, percentage change can not be calculated such as when there were 0 crashes in either time period

Pedestrian Summary Table Description

The table is sorted by counties in alphabetical order but the sorting can be changed depending on user preferences  by clicking the column headers. 

Bicylist Summary Table Description

Table of California counties detailing the average number of bicyclist FSI from 2014 to 2016,  average number of bicylcist FSI from 2021 to 2023, and the percentage change etween these periods. The table is sorted by counties in alphabetical order but the sorting can be changed depending on user preferences  by clicking the column headers.

Pedestrian Fatalities and Fatalities per Capita (100k) in California 

Pedestrian Fatalities and Fatalities per Capita (100k) Maps Description

Two Choropleth maps of California counties detailing the total number of pedestrian fatalities and fatalities per Capita (100k) in each county from 2020 to 2024. Counties with more pedestrian fatalities (or fatalities per Capita (100k))  are colored with red tones, while those with less pedestrian fatalities (or fatalities per Capita (100k)) use yellow tones. For more information, including the pedestrian serious injuries and serious injuries per Capita, please see the summary table below.

Pedestrian Summary Table Description

Table of California counties detailing the total number of pedestrian fatalities, fatalities per Capita (100k), serious injuries and serious injuries per Capita (100k) in each county from 2020 to 2024. The table is sorted by counties in alphabetical order and then by year. 

Bicycle Safety

Bicyclist Fatalities and Fatalities per Capita (100k) in California

Bicyclist Fatalities and Fatalities per Capita (100k) Description

Two Choropleth maps of California counties detailing the total number of pedestrian fatalities and fatalities per Capita (100k) in each county from 2020 to 2024. Counties with more pedestrian fatalities (or fatalities per Capita (100k)) are colored with dark blue, while those with less bicyclist fatalities (or fatalities per Capita (100k)) use light blue tones. For more information, including the bicyclist serious injuries and injuries per Capita, please see the Summary Table below.

Bicycle Summary Table Description

Table of California counties detailing the total number of bicyclist fatalities, fatalities per Capita (100k), serious injuries and serious injuries per Capita (100k) in each county from 2020 to 2024. The table is sorted by counties in alphabetical order and then by year. 

Note: 

Pedestrian and bicyclist fatality per capita and serious injury per capita (100k) rates were calculated based on the total number of fatalities and serious injuries in a county for that year divided by the total population (per 100k) in a county for that year respectively. For the pedestrian and bicyclist fatality per capita (100k) rates used in the map visuals, the total number of pedestrian and bicyclict fatalities was respecively summed over the 5 year period and then divided by the total 100k population. Population data was collected from the State of California Department of Finance.  https://dof.ca.gov/forecasting/demographics/estimates
