There are typically many contributing factors in motor vehicle crashes. Emergency Medical Services (EMS) play a critical role post-crash to reduce fatalities and serious injuries. Recent studies show that an effective emergency trauma care system can improve survival from serious injuries by as much as 25 percent and county-level coordinated systems of trauma care can reduce crash fatalities rates as much as 50 percent.

The Haddon Matrix (see Figure 1) applies basic principles of public health to motor vehicle-related injuries. The matrix looks at the factors in the pre-crash, crash...

NEW! SWITRS Statewide Summary Tool on TIMS

September 20, 2021

UC Berkeley SafeTREC’s Transportation Injury Mapping System (TIMS) has been developed to provide quick, easy and free access to California crash data from the Statewide Integrated Traffic Records System (SWITRS) that has been geo-coded to make it easy for users to query, map, and download collision data.

As part of an ongoing effort to support local and state agencies efforts to improve traffic safety, a new tool is now available, the...

New Research Highlight: Selected Research on Road Diets

May 5, 2021
Research highlights how road diets have been shown to reduce traffic injury

SafeTREC's graduate student researcher Elijah Wade and research analyst Bor-Wen Tsai have co-authored a new research highlight, "Selected Research on Road Diets."

Abstract Pedestrian and bicyclist injury and mortality is a common occurrence in California. Data from the Transportation Injury Mapping System found that serious injuries among bicyclists and pedestrians increased between 2017-2019, with 3,174 recorded in 2017 and a peak of 3,495 serious injuries in 2019. Along with serious injuries, there has also...

New Research Highlight: Commercial vehicles, fatigue, parking, and safety

August 30, 2020

UC Berkeley SafeTREC is excited to share a new research highlight by research analyst Katherine Gosselin, "Commercial vehicles, fatigue, parking, and safety."

New research highlight focuses on the public health and road safety hazards of commercial driver operator fatigue and not having access to truck parking

For commercial drivers, operator fatigue and parking in undesignated areas can result in dangerous collisions. Exacerbating this issue is a lack of freight truck parking, making it difficult for truck operators to find a safe spot when in need of rest. For bicyclists and...

Commercial vehicles, fatigue, parking and safety

For commercial drivers, operator fatigue and parking in undesignated areas can result in dangerous collisions. Exacerbating this issue is a lack of freight truck parking, making it difficult for truck operators to find a safe spot when in need of rest. For bicyclists and pedestrians, loading and unloading commercial vehicles in downtowns also present hazards. Increasing the availability of legal truck parking could improve safety for all road users.

While alcohol-impaired driving fatalities have fallen significantly in the last three decades, NHTSA reports that alcohol-impaired driving still comprises a large percentage of traffic injuries and fatalities. On average in 2018, one person died from an alcohol impaired driving crash every 50 minutes. There was a decrease in the number of alcohol-impaired driving fatalities and rate per 100 million VMT in the United States between 2017 and 2018. Analyses from SWITRS presented in this program area refer to alcohol involvement and include fatalities and serious injuries where law enforcement...
