Recent mobility trends reveal that travel is becoming increasing multi-modal in nature. Given the increase in the emphasis on multi-modal mobility there is a need to efficiently account for the multi-modal safety challenges it introduces. In light of this, it is of immense concern that the corresponding improvements made to traffic safety have not been commensurate across all modes. In this regard, one of the major challenges associated with efficiently designing and planning for a safe multi-modal environment is a limited understanding of multi-modal traffic behavior as explained by...

Strategies for Reducing Pedestrian and Bicyclist Injury at the Corridor Level

2011

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...

Estimation of Pedestrian Risk Exposure in Urban Areas : Case studies in the US and in France

Do, Minh-Tan

Cerezo, Veronique
2013
The paper deals with the estimation of pedestrian risk exposure in urban areas. The approach proposed is based, on the one hand, on a spatial analysis technique called Space Syntax that characterizes the street integration - how streets are connected to each other - which gives rise to a natural movement of persons, and on the other hand, on land-use which acts as a multiplier or a divider of the original flows. Street integration is weighted by factors related to land use to better captures the heterogeneity of street-blocks. The method is applied to two radically different urban spaces: the...

Community Pedestrian Safety Training: Action Plans

October 29, 2015

Our Community Pedestrian Safety Training (CPST) program with California Walks is a four-hour, community-based workshop designed to help local advocates and community members develop pedestrian safety action plans that leverage best practices, promote walkability and ensure community engagement.

This year, we were honored to work with...

How Common is Pedestrian Travel To, From, and Within Shopping Districts?

Schneider, Robert J.
Pande, Swati
2012

Growing interest in sustainable transportation systems and livable communities has created a need for more complete measures of pedestrian travel. Yet, many performance measures do not account for short pedestrian movements, such as walking between stores in a shopping district, walking from a street parking space to a building entrance, or walking from a bus stop to home. This study uses a 2009 intercept survey and the 2009 National Household Travel Survey to quantify pedestrian travel to, from, and within 20 San Francisco Bay Area shopping districts. Overall, walking was the...

Do All Roadway Users Want the Same Things?

Sanders, Rebecca L.
Cooper, Jill F.
2013

This paper presents findings from a recent study on roadway design preferences among pedestrians, drivers, bicyclists, and public transit users along a major urban corridor in the East San Francisco Bay Area. Sponsored by the California DOT, the research focused on exploring design preferences that could increase perceived traffic safety, walkability, bikability, and economic vitality along urban arterials. Results from an intercept survey showed that all user groups desire similar roadway design features along the test corridor, which carries 25,000-30,000 motorists bi-directionally...

Pedestrian and Bicycle Safety Evaluation for the City of Emeryville at Four Intersections

Johnson, Emily S.
Ragland, David R.

O'Connor, Terri
2005

The City of Emeryville is small in area (1.2 square miles) and population (7,000), but it is one of the most regionally connected cities in the Bay Area (California). Emeryville is situated at the eastern end of the San Francisco-Oakland Bay Bridge, contains the intersection of Interstate Highway 80 (I-80) with several regional and other interstate highways, and has extensive transportation access by Amtrak Rail, Alameda County (AC) Transit and heavy cargo facilities at the nearby Port of Oakland. The city has many large employers and several large shopping areas, and the daytime...

Low Income Childhood Pedestrian Injury: Understanding the Disparate Risk

Johnson, Emily S.

2004

A leading cause of death and injury to children is being struck by a motor vehicle. A disproportionate number of injured child pedestrians are of low socioeconomic status. The relationship between socioeconomic status and pedestrian injury is poorly understood. The existing literature is limited by the lack of pedestrian exposure data, a common measure of risk, and a clear conceptual framework for the interaction between socioeconomic status and pedestrian injury. Another issue is the limited availability of injury data. This paper proposes a model for understanding child pedestrian...

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...
