A strategic highway safety plan (SHSP) is a comprehensive, statewide, data-driven safety plan that coordinates activities across agencies to reduce traffic fatalities and serious injuries on all public roads. In 2015, California updated its SHSP with the input of hundreds of stakeholders. To implement a multiyear effort that involves many primary actors, the challenge is to track decisions and progress in an efficient manner as well as to have in place a state safety program that is accountable and transparent to its stakeholders. The Safe Transportation Research and Education Center at...

Drivers, Pedestrians, and Cyclists in California Want Complete Streets: Comparison of Results from Roadway Design Surveys of Pedestrians, Drivers, Bicyclists, and Transit Users in Northern and Southern California

This paper compares findings from two recent surveys on roadway design preferences among pedestrians, drivers, bicyclists, and public transit users along major urban corridors in the metro areas of San Francisco and Los Angeles. Sponsored by the California Department of Transportation (DOT), the research explored design preferences that could increase perceived traffic safety, walkability, bikability, and economic vitality along urban arterials. Results from intercept surveys showed that roadway users desire similar design features along the test corridors, which carry 25,000-40,000...

Experimental Research of Relationship between Pedestrian Stopping Distance and Walking Speed to Avoid Pedestrian Crowd Stampede Accident

Stampede accidents usually take place in crowded areas in transfer stations, sports stadiums, shopping malls, religious places and other similar areas. One of the causes of stampedes is that people do not have enough distance to stop themselves when there are emergencies. Like vehicles, pedestrians also need stopping distance when they want to stop from a certain speed, especially in a sudden situation without any previous notice. People who could not stop in time crush into or step upon other people, and may trigger a stampede accident. Analysis of worldwide stampede accidents reveals the...

Wayfinding-Oriented Design for Passenger Guidance Signs in Large-Scale Transit Center in China

2010

Transit centers should offer well-designed guidance signs to help passengers find their way to desired destinations easily and quickly. The current design of guidance signs in large-scale transit centers in China, however, is based almost solely on interior and art design, with virtually no accounting for passengers’ wayfinding requirements. As a tentative effort to fill that need, this study presents a wayfinding-oriented design for guidance signs. The case of a large transit center in China is used to illustrate how wayfinding requirements can be incorporated into specific design. In...

Community Engagement at the Intersection of Public Health and Transportation: Highlighting Community Based Organizations’ Use of the Promotores Model for Engaging Community Members in the Field of Transportation

Ana Lopez
2023

Under federal statutes, transportation planners have an obligation to actively engage community members and to conduct equity-based analyses on transportation plans to ensure that people of color, low-income people, and other historically disenfranchised groups are neither disproportionately burdened nor denied the benefits of transportation investments. Planning professionals have an ethical and moral responsibility to involve and engage the communities they serve—to intentionally center community members in planning decision-making processes regarding their communities and ensure equity...

Research Brief: Towards a Better Understanding of Best Implementation Practice for the Community Pedestrian and Bicycle Safety Training Program

September 25, 2023
New research brief highlights effectiveness and progress of the CPBST, and features case studies with community partners on how the program can be strengthened

A new research brief, Towards a Better Understanding of Best Implementation Practice for the Community Pedestrian and Bicycle Safety Training Program, co-authored by UC Berkeley SafeTREC's Aqshems Nichols, Areli A. Balderrama, and Katherine L. Chen explores the program effectiveness and...

Research Brief: The Influence of Alcohol Outlet Proximity on Pedestrian Injury Incidence: Insights from Literature

September 8, 2023
New research brief explores potential association between the presence of alcohol outlets and pedestrian injuries

According to the latest annual Spotlight report from the Governors Highway Safety Association (GHSA), there were 7,508 pedestrian fatalities in 2022, the highest number of people killed while walking since 1981. Preventing these pedestrian crashes is a critical concern, and researchers and road safety professionals have conducted studies to examine why these crashes occur in the first place and...

Research Brief: Towards a Safer California: Addressing the Road Safety Needs of Older Adults

July 19, 2023
New research brief explores the factors that contribute to road safety needs of older adults

With an aging state population, it is crucial to understand the factors that contribute to road safety among adults aged 65 and older and identify at-risk neighborhoods for targeted interventions. In a new research brief, Towards a Safer California: Addressing Road Safety Needs of Older Adults, UC Berkeley SafeTREC's Graduate Student Researcher Lekshmy Hirandas analyzes fatal and serious injury (FSI) trends and patterns among aging road users, including older pedestrians and...

2023

Preventing roadway deaths and injuries due to motor vehicle crashes continues to be a prevailing public health challenge in the United States. Included in this challenge is improving the safety of pedestrians on street and road networks. Researchers and other professionals continue to develop best practices for ameliorating the outcomes of pedestrian crashes by conducting studies that examine why these crashes occur and what steps can be taken to prevent them in the future. To do this, many researchers have employed a systems approach to addressing pedestrian safety by acknowledging that...
