Crash Data Tools and Resources

National Highway Traffic Safety Administration (NHTSA) 

NHTSA provides a wide range of analytical and statistical support to the highway safety community, including the following crash data systems:

• Crash Investigation Sampling System (CISS)
• Crash Report Sampling System (CRSS)
• Fatality Analysis Reporting System (FARS)
• Fatality and Injury Reporting System Tool (FIRST)
• National Automotive Sampling System (NASS)
• National Center for Statistics and Analysis (NCSA) FARS and GES/CRSS query reporting tools and traffic safety publications
• Special Crash Investigations (SCI)
• Non-Traffic Surveillance (NTS)

National EMS Traffic Crash Dashboard

The national EMS Traffic Crash Dashboard provides up-to-date information for EMS activations where the cause of injury was reported as motor vehicle-related across all 50 states, three territories and the District of Columbia—approximately 50 million EMS activations each year. The dashboard elements are collected using the national standard for EMS data and represent 90% of all EMS responses. Data is collected in near real time with most states reporting complete data within 8 days.

This data can be used to characterize and understand traffic incident mortality and morbidity and can also serve as a valuable tool for planning and prevention activities. 

California Crash Reporting System

The California Crash Reporting System (CCRS) is a database that collects, and processes crash records from within the State of California provided from the California Highway Patrol (CHP). 

Transportation Injury Mapping System (TIMS)

For over twenty years, the Transportation Injury Mapping System (TIMS) developed by UC Berkeley SafeTREC has enabled quick, easy, and free access to California crash data by geocoding crashes within the Statewide Integrated Traffic Records System (SWITRS) database and providing a variety of point-and-click tools. Users can now create crash summaries, conduct their own traffic safety data analysis, and visualize autonomous vehicle crashes and mileage data in California. Learn more about the TIMS tools below.

Crash Summaries

4 tools that aggregate maps, tables and charts to summarize key traffic safety crash trends in California on a state, county and city level. Learn more about the crash summary tools

Data Analysis and Visualizations

7 different crash and geospatial analysis tools that allow users to visualize and compare SWITRS data across California. Learn more about the data analysis tools.

Autonomous Vehicle Safety

2 dashboards to visualize autonomous vehicle (AV) crashes and mileage in California reported through the AV Testing and AV Driverless Testing Permits from the California Department of Motor Vehicles (DMV). Learn more about the AV safety tools

California Office of Traffic Safety (OTS)

OTS Crash Rankings

The California Office of Traffic Safety (OTS) Crash Rankings were developed so that individual cities could compare their city’s traffic safety statistics to those of other cities with similar-sized populations. Cities could use these comparisons to see what areas they may have problems in and which they were doing well in. The results helped both cities and OTS identify emerging or on-going traffic safety problem areas in order to help plan how to combat the problems and help with the possibility of facilitating grants. In recent years, media, researchers and the public have taken an interest in the OTS Rankings. It should be noted that OTS rankings are only indicators of potential problems; there are many factors that may either understate or overstate a city/county ranking that must be evaluated based on local circumstances.

OTS Data and Statistics Resources

• California Traffic Safety Quick Stats (Fast Facts)
• National Traffic Research and Analysis (NCSA)
• California Department of Motor Research Studies and Reports
• California Demographic, Economic, and Financial Research (DOF)
• National Transportation Statistics
• California Office of Traffic Safety (OTS) Traffic Safety Resources

California Strategic Highway Safety Plan (SHSP) Crash Data Dashboard

Caltrans has developed the California SHSP Crash Data Dashboard to provide SHSP implementers with direct access to crash data to support data-driven implementation of the SHSP. The dashboard currently uses finalized crash data from the Fatality Analysis Reporting System (FARS) and the Statewide Integrated Traffic Records System (SWITRS). Some filtering options include:

• SHSP Challenge Area
• Crash Severity
• Location: District, County, Metropolitan Planning Organization (MPO), and City
• Crash Cause
• Crash Time
• Crash Party and Victim Demographics

NEW: 

• The SHSP is excited to include provisional data within the Crash Data Dashboard for preliminary data review. Provisional data is an incomplete dataset that is being released sooner than the finalized data in order to provide our stakeholders with more timely information.

Street Story

Street Story is a community engagement platform provided by UC Berkeley SafeTREC in English and Spanish that allows residents, community groups, and agencies to collect information about transportation crashes, near misses, general hazards, and safe locations to travel. The tool is free to use, anonymous, and publicly accessible. Street Story is not a substitute for reporting crashes to the police.

Overview of Street Story features

Features	Snapshot
Street Story platform  Available in English and Spanish, the Street Story reporting platform allows the public to input information including narratives about transportation crashes, near-misses, general hazards and safe locations to travel throughout California.	The Street Story Reports feature displays a Report Map that indicates the location of submissions and provides data summaries, charts, and graphs. It also displays a new toggle button to compare travel experiences shared by community members and residents to fatal and serious injury crash data that has been collected by the California Highway Patrol.
Street Story Reports Available in English and Spanish, Street Story Reports is a feature that provides summaries, charts and graphs about the information that has been collected. It provides a Report Map that indicates the locations of submissions throughout California. Reports can also be filtered by date and provide demographic information of respondents.  NEW - Street Story Reports now displays a toggle button that allows users to view crowdsourced transportation data from the platform alongside statewide crash data from the Statewide Integrated Traffic Records System (SWITRS).	The Street Story Reports feature displays a Report Map that indicates the location of submissions and provides data summaries, charts, and graphs. It also displays a new toggle button to compare travel experiences shared by community members and residents to fatal and serious injury crash data that has been collected by the California Highway Patrol.
Street Story Custom Boundary Available in English and Spanish, the Street Story Custom Boundary feature allows community members and agencies to create and share their own interest area. They can do so by drawing or uploading their own boundary using the drawing tool on the map, or by uploading a shapefile. More information about this feature can be found in the Street Story Custom Boundary Instructions (available in English and Spanish).
