About the Transportation Injury Mapping System (TIMS)

TIMS has been established by researchers at the Safe Transportation Research and Education Center (SafeTREC) at the University of California, Berkeley to provide data and mapping analysis tools and information for traffic safety related research, policy and planning.



SafeTREC began assessing the usage of the California Statewide Integrated Traffic Records System (SWITRS) by state and local agencies in 2003 on a project funded by the California Office of Traffic Safety (OTS).  Specifically, the project looked at the needs of agencies to geocode and map the collisions in an efficient and simple manner.  The lack of expertise or capabilities at many agencies did not allow any geographic analysis of traffic collisions and resulted in exorbitant consulting expenses, redundancy of various efforts, technical difficulties, inaccuracy, and other problems.  Further grants from OTS allowed SafeTREC to develop a geocoding methodology and apply it to SWITRS data statewide.  In order to distribute the geocoded SWITRS data, a web-based data query and download application was developed with the ability to display pin maps in Google Maps.  A second application was designed to provide a more map-centric experience with other types of data layers and spatial analysis capabilities typically seen in a Geographic Information System (GIS).  The TIMS concept was subsequently formed to give these applications a common foundation and provide a framework for continued development in the future. 


Traffic Collisions – An overview

Traffic collisions, despite national and statewide progress, remain a tremendous burden on personal lives and society. While motor vehicle crashes typically take mere seconds to occur, the personal tragedies, heartbreak, and impact on families and communities can last a lifetime.  Estimates of the occurrence and cost of motor vehicle crashes cannot begin to describe the massive toll and disruption to American lives. 


In 2007, California recorded 3,967 deaths and 266,687 injuries.  This includes not only drivers of vehicles, but other roadway users such as pedestrians and bicyclists as well.  The resulting cost of these collisions to California was $25,661,000,000 (SWITRS). In the United States, motor vehicle collisions are already the leading cause of death for people between the ages of 3 and 34.  For all ages of people, 33,808 people died in motor vehicle collisions and 2,217,000 were injured in 2009 alone. These collision facts are provided by the National Highway Traffic Safety Administration through a yearly series of publications known as the Traffic Safety Facts. The Traffic Safety Facts series also provides targeted fact sheets for pedestrians, bicyclists, motorcycles, trucks and other types of collisions.


California has adopted the slogan “Toward Zero Deaths, Every 1 Counts” (TZD) as a guiding philosophy of traffic safety.  With TZD, California officially proclaims that not a single traffic fatality is acceptable.  Given this philosophy guiding state highway safety planning, it is critical to work efficiently and effectively to target safety efforts, to identify significant opportunities for safety improvement, and to focus efforts on eliminating severe crashes.


In California, the California Highway Patrol (CHP) collects and disseminates traffic crash data. These reports help the California Office of Traffic Safety (OTS) and other agencies lead traffic safety efforts to produce significant and measureable reductions in crashes.

Finally, on a global scale, traffic collisions are also a growing problem as the population levels and use of all types of motor vehicles continue to increase.  In fact, by 2020, motor vehicle collisions are expected to be the leading source of unintentional injury or death worldwide according to a report published by the World Health Organization.

Future Plans

We hope to continue to further develop TIMS by increasing the available resources, updating current tools and developing new tools for transportation injury analyses.
