New Release: California Traffic Safety Survey 2020

July 22, 2020

UC Berkeley SafeTREC is excited to release the California Traffic Safety Survey 2020 led by Ewald & Wasserman Research Consultants (E&W). This study was conducted on behalf of the California Office of Traffic Safety (OTS) and the Safe Transportation Research and Education Center (SafeTREC) at the University of California, Berkeley.

COURSE OVERVIEW

Injury is the leading cause of death for ages 1-44, and the leading cause of years of potential life lost to age 65, surpassing heart disease and cancer.

Restraint devices such as seat belts are a key element of motor vehicle occupant protection systems. Each year, the National Highway Traffic Safety Administration (NHTSA) conducts the National Occupant Protection Use Survey (NOPUS) that measures, among many variables, the use of seat belts by occupants age eight and older. The 2018 NOPUS reported an 89.6 percent front seat belt use rate for the nation as a whole, which was essentially level with the 89.7 percent rate in 2017.

Collisions involving motorcycles are a major traffic safety concern in the United States. Motorcycle riders comprise a disproportionate share of all injured and killed vehicle occupants. In 2016, motorcycle riders were 28 times more likely than passenger car occupants to be fatally injured in a traffic collision, per vehicle miles traveled.

This study examines data from the California EMS Information System (CEMSIS) to identify factors that influence prehospital time for EMS events related to motor vehicle collisions (MVCs). While only 19 percent of the United States population resides in rural areas, over half of all traffic fatalities involve rural motor vehicle collisions.

Prehospital Response Time and Traumatic Injury—A Review

A significant proportion of fatalities from motor vehicle collisions (MVC) could be prevented through better emergency medical service (EMS) care. Despite a lack of conclusive research, there is a consensus that prehospital time (the time between the MVC and the patient’s arrival at the hospital) must be reduced as much as possible. Many studies use response time (the time between EMS dispatch and arrival at the scene) as an indicator of overall prehospital time and a metric of EMS performance.

Reflections on the 2019 Safe Systems Summit: Redefining Transportation Safety

June 7, 2019

According to the latest data from the National Highway Traffic Safety Administration (NHTSA), there were 37,133 traffic fatalities on U.S. roadways in 2017, a 1.8-percent decrease from the 37,806 people killed in 2016. While there has been a general downward trend downward in traffic fatalities overall, this is still an alarmingly high number of deaths – and there have been troubling increases for vulnerable road users like pedestrians.

SafeTREC Traffic Safety Facts: Speeding-Related Collisions

A speeding-related collision is defined as one in which a driver is racing, driving too fast for the conditions, or driving in excess of the posted speed limit. In the United States, speeding has been involved in nearly one-third of all fatal crashes for more than twenty years and is a leading contributing factor in traffic collisions. Speeding reduces a driver’s ability to steer safely around curves or objects, reduces the amount of time a driver has to react to a dangerous situation, and extends safe stopping distances.
