Road fatalities are rare outcomes of events that occur in a small time-space region. Although the exact chain of events for each fatality is unique, there are inherent similarities between road fatalities. The science of road safety is dedicated to identifying such similarities, mainly using statistical analysis tools. Researchers typically analyze patterns that emerge over space, such as hot-spot studies, or patterns that emerge over time, such as before-after studies. Traffic research enumerates 84 parameters that characterize a road fatality. A vast number of papers have tried to...
New research brief explores the existing bicycle infrastructure in the City of Oakland as it relates to cyclist safety
Climate change has caused unprecedented problems, which has increased efforts to fund sustainable green alternatives, including funding for alternative means of transportation such as active transportation and micro-mobility infrastructure improvements. In a new research brief, Perceptions of Bicycle Safety: A Data and User-Experience Approach, UC Berkeley SafeTREC's Graduate Student Researcher Greg Harasym explores existing bicycle infrastructure in the...
This year SafeTREC faculty, staff and graduate students joined over 13,000 transportation professionals from around the world at the Transportation Research Board 99th Annual Meeting from January 16-20, 2020 in Washington, D.C. Our team had the opportunity to present some of our latest transportation safety research, participate in various events, workshops and activities, and connect with alum. Enjoy our round-up of selected photos to share what we were up to at #TRBAM!
Crash data is readily available and accessible for public use through government information databases. Crash data typically entails vehicle-related injuries and fatalities that were reported to police authorities. But what about unreported incidents--incidents that only require exchange of contact and insurance information, incidents that may not involve an injury or injuries that might not have been reported? As a way to understand perceptions and experiences of safety in communities, UC Berkeley SafeTREC is developing an online data tool that allows people to self-report...
State Superintendent of Public Instruction, Tom Torlakson, with staff from the California Department of Education, California Office of Traffic Safety and SafeTREC.
On November 2, 2017, SafeTREC co-director Jill Cooper and researchers SangHyouk Oum and Liwei Fu presented SafeTREC’s latest data and mapping analysis tool, the Teen Safety Heat Map at the 2017 Geographic Information Systems...
Methods for identifying sites with potential for preventing traffic fatalities and injuries have been developed for vehicle-vehicle collisions. This study was funded by the California Department of Transportation (Caltrans) to develop methods for identifying sites where there is potential for significant reductions in pedestrian and bicyclist injury. Data from 1998-2007 from a 16.5-mile section of San Pablo Avenue (SR 123) in the San Francisco East Bay was used as a study area. Several approaches for identifying sites with high potential for reducing pedestrian and bicyclist injury were...
