Roadway Safety and Traffic Records

Roadway Safety programs concentrate on the vehicle operating environment and are strongly influenced by enforcement, engineering, and utilizing relevant data generated by those activities to improve roadway safety and traffic records. OTS advocates efforts to automate traffic collision database systems and the ability to analyze and map high-collision locations. Grant-funded items include hardware, software, and expert services necessary to aid in the automation of manual processes, eliminate process duplication, and facilitate enhanced data gathering and data sharing.


  • To replace manual input databases or paper files, allowing traffic engineers access to extensive collision analysis tools, automated standard reports, and mapping of collision locations


California Active Transportation Information Pages
SafeTREC at UC, Berkeley created a new and improved website for the California Active Transportation Information Pages (CATSIP). The new website features a more visual and engaging approach toward presenting the latest and most useful online resources to encourage and promote safety for pedestrians, bicyclists, and other non-motorized road users in California. This year, the CATSIP website received more than 15,225 visits by more than 13,335 visitors, for a total of 32,141 page views. In addition, the new CATSIP website is more dynamic, responsive, easier to use, and includes blog posts, articles, resources, funding opportunities, and a weekly spotlight feature.

California EMS Information System
The Emergency Medical Services Authority (EMSA) increased the availability to researchers and the public for the study of post-crash survivability. It was accomplished by completing the transformation of local and state data operations to the nationally recognized formats known as National EMS Information System (NEMSIS) Version 3 and creating new, open data resources for EMSA public website. Data integration is a priority throughout all project activities, and EMSA continued its partnership with the California Department of Public Health to achieve data linkage objectives.

Crash Medical Outcomes Data
California’s traffic safety and injury prevention communities need comprehensive “crash to outcome” data that are critical to identifying and solving traffic safety problems. The Crash Medical Outcomes Data (CMOD) Project responded to the need and the vision of NHTSA’s Traffic Records Coordinating Committee. The project further built the successful data linkage between crash data and medical data in several ways. It translated linked data into actionable information, made linked crash medical data available to stakeholders and the general public, provided data to partners for special projects, provided expert consultation to partners on data linkage methodology, and integrated multiple data sources into a comprehensive traffic records system. The CMOD project also leveraged existing expertise and resources to improve data quality and access by sharing data and knowledge across partner agencies. California to be safer from the sidewalk to the center line for motorists, pedestrians, and bicyclists.

Transportation Injury Mapping System
The University of California, Berkeley SafeTREC Program improved the Transportation Injury Mapping System (TIMS) data and application. TIMS, a web-based interactive collision mapping and data resource based on the SWITRS database with over 6,000 registered users from key agencies such as the CHP, local police agencies, state agencies, city and county governments, universities and non-profit agencies, has been updated to include the pedestrian summary and victim level summary result pages in the SWITRS Query and Map tool. Also, the 2013 and 2014 SWITRS data were geocoded and added on TIMS. TIMS now has approximately 2 million collision records, 4 million party records, and 4.6 million victim records from 2004 to 2014.
