Oakland Chinatown Pedestrian Scramble: An Evaluation

Bechtel, Allyson K.
MacLeod, Kara E.
Ragland, David R.
2003

In 2002, the City of Oakland, California implemented a scramble signal, at the intersection of 8th Street and Webster Street. Scrambles are a type of traffic signal that give pedestrians exclusive access to an intersection by stopping vehicular traffic on all approaches, allowing pedestrians to cross diagonally or conventionally. The primary objective of this evaluation was to determine whether the installation of the pedestrian scramble at this location increased pedestrian safety. An analysis was conducted of pedestrian-vehicle conflicts and pedestrian violations occurring at the...

Traffic Safety in Communities of Color

2003

Over the past half-century in the United States, medical advances, improvements in road and vehicle design, and traffic safety efforts have all helped in reducing traffic-related injury and death. However, research suggests that among the US population, certain ethnic groups, namely African Americans,* American Indians, and Latinos, continue to face higher traffic-related risk. Among all US ethnic groups, motor-vehicle injury is a leading contributor to unnecessary injury and premature death. Improving traffic safety outcomes among these groups could help reduce their overall health...

Space Syntax: An Innovative Pedestrian Volume Modeling Tool for Pedestrian Safety

Raford, Noah
Ragland, David R.
2003

This paper describes an innovative pedestrian modeling technique known as Space Syntax, which was used to create estimates of pedestrian volumes for the city of Oakland, California. These estimates were used to calculate pedestrian exposure rates and to create a Relative Risk Index for the city’s first pedestrian master plan. A major challenge facing planners, transportation engineers, and pedestrian-safety advocates is the lack of detailed and high quality pedestrianexposure data. Exposure is defined as the rate of contact with a potentially harmful agent or event. Pedestrian exposure is...

An Intensive Pedestrian Safety Engineering Study Using Computerized Crash Analysis

Ragland, David R.
Markowitz, Frank
MacLeod, Kara E.
2003

Over the past year, the San Francisco Department of Parking and Traffic (DPT) conducted an intensive pedestrian-safety engineering study, the PedSafe Study. PedSafe was funded by the Federal Highway Administration (FHWA)*, which also funded companion studies in Las Vegas and Miami. The study was designed to analyze pedestrian injuries by zones (i.e., neighborhoods or districts) and to identify those most amenable to prevention efforts. The DPT expects to utilize the methodology and information from the PedSafe study to help shape a citywide pedestrian master plan. This paper describes the...

Driver/Pedestrian Understanding and Behavior at Marked and Unmarked Crosswalks

Mitman, Meghan F.
Ragland, David R.
2008

Pedestrian injuries at crosswalk locations represent a significant problem. In 2002, 22.7 percent of US pedestrians involved in collisions were in a crosswalk at the time of the collision, and over 96% of these occurred at an intersection. Almost all crosswalk collisions resulted in pedestrian injury or fatality (98.6 percent), and about one-third resulted in severe or fatal injury (National Automotive Sampling System (NASS) and General Estimates System (GES) 2002). As the owner of the California State Highway System, Caltrans is responsible for providing access to safe and...

Seamless Travel: Measuring Bicycle and Pedestrian Activity in San Diego County and its Relationship to Land Use, Transportation, Safety, and Facility Type

2010

This paper provides the data collection and research results for the Seamless Travel project. The Seamless Travel Project is a research project funded by Caltrans and managed by the University of California Traffic Safety Center, with David Ragland, PhD., as the Principal Investigator and Michael Jones as the Project Manager. The project is funded by Caltrans Division of Innovation and Research and is being conducted by the Traffic Safety Center of University of California Berkeley and Alta Planning + Design. Measuring bicycle and pedestrian activity is a key element to achieving the goals...

Safe Routes to School Local School Project: A health evaluation at 10 low-income schools

Cooper, Jill F.
McMillan, Tracy
2010

The Safe Routes to School National Partnership (Partnership) founded the Local School Project (Project) in 2008 to assist ten schools in lowincome communities to: 1) develop and evaluate a school-based SRTS program, 2) build local capacity to apply for state or federal SRTS funding, and 3) increase safe walking and bicycling to and from the school and in the community. The Centers for Disease Control and Prevention, Kaiser Permanente, and the Robert Wood Johnson Foundation provided funding for the Project. This report presents the results, lessons learned and recommendations...

Performance Measures for Complete, Green Streets: Initial Findings for Pedestrian Safety along a California Corridor

Sanders, Rebecca L.
Macdonald, Elizabeth

Ragland, David R.
Cooper, Jill F.
2011

This paper reports on research conducted by the Safe Transportation Research and Education Center and sponsored by the California Department of Transportation (“Caltrans”) to establish performance measures for pedestrian and bicycle safety and mobility along urban arterials. Although historically focused on motorized vehicle mobility, Caltrans has recently joined in a national trend to incorporate non-motorized transportation and community-level outcomes into transportation decision-making frameworks, an approach known as "Complete Streets." Recognizing that its current performance...

Community Pedestrian Safety Engagement Workshops in California

Babka, Rhianna JoIris
Cooper, Jill F.
Alfsen, Wendy
Sabin, Marilyn
2011

The Community Pedestrian Safety Engagement Workshops are a community capacity building program to involve local residents in community pedestrian safety. The focus of these workshops is to engage, educate and empower residents to ensure they have the skills, knowledge and resources they need to become active in improving pedestrian safety in their neighborhood, district, city or county. This program uses pedestrian planning and community engagement curriculums as a framework for the content, and goes beyond this to tailor each workshop to the individual community needs, ensuring genuine...

We All Want the Same Thing Results from a Roadway Design Survey of Pedestrians, Drivers, Bicyclists, and Transit Users in the Bay Area

Sanders, Rebecca L.
Cooper, Jill F.
2012

Pedestrians, bicyclists, drivers, and public transit users all desire similar roadway design features, at least according to findings from a recent intercept survey of 537 people along a major urban corridor in the San Francisco Bay Area. This research was sponsored by the California Department of Transportation to understand traveler preferences for street design that could increase perceived traffic safety, walkability, and bikability along urban arterials, as well as encourage economic vitality through increased patronage of local businesses. In an open-ended question about street...
