Pedestrian and Bicycle Safety Research Brief

Barajas, Jesus M.
2016

As cities around the country adopt initiatives like Vision Zero to eliminate traffic deaths and serious injuries, they are faced with the question of how effective different types of interventions are. For example, do protected bike lanes or painted sharrows reduce the risk of severe injury to cyclists? A group of researchers from the New York University School of Medicine examined this question by studying where cyclists admitted to the hospital crashed and how severe their injuries were. This research brief explores their findings.

Pedestrian and Bicycle Safety Research Brief

2017

In January 2017, over 13,000 transportation professionals gathered in Washington, DC, at the Annual Meeting of the Transportation Research Board (TRB). In all, there were over 5,000 research presentations, 600 of which were about transportation safety. In this brief, we highlight some of the newest practice-ready pedestrian and bicycle safety research to come out of the conference.

Data is the bread and butter of safety analysis. This research brief highlights three new peer-reviewed studies that focus on questions around pedestrian and bicycle safety data and the patterns they identify. Read the full Pedestrian and Bicycle Safety Research Brief to explore our findings

Motor vehicle speed as a risk factor in pedestrian safety

McMillan, Tracy
Cooper, Jill F.
2019

Speed is a significant risk factor in road safety. Several recent reports from the National Transportation Safety Board (NTSB) and the Governors Highway Safety Administration (GHSA) highlight the need for a greater focus on speed management at the national, state and local level. As part of our Community Pedestrian and Bicycle Safety Program (CPBSP), UC Berkeley SafeTREC has prepared a new research brief, "Motor vehicle speed as a risk factor in pedestrian safety"...

Pedestrian Count Expansion Methods: Bridging the Gap between Land Use Groups and Empirical Clusters

April 16, 2019
New Paper Published by SafeTREC Researcher Aditya Medury

SafeTREC postdoctural researcher Aditya Medury has co-authored a newly published paper, "Pedestrian Count Expansion Methods: Bridging the Gap between Land Use Groups and Empirical Clusters" with researchers Julia B. Griswold, Louis Huang and Offer Grembek in the Transportation Research Record: Journal of the Transportation Research Board.

Count expansion methods are a useful tool for creating long-term pedestrian or cyclist volume estimates from short-term counts for safety analysis or planning purposes. Expansion factors can...

Pedestrian Count Expansion Methods: Bridging the Gap between Land Use Groups and Empirical Clusters

Count expansion methods are a useful tool for creating long-term pedestrian or cyclist volume estimates from short-term counts for safety analysis or planning purposes. Expansion factors can be developed based on the trends from automated counters set up for long periods of time. Evidence has shown that the activity patterns can vary between sites so that there is potential to create more accurate estimates by grouping similar long-term count trends into factor groups. There are two common approaches to developing factor groups in pedestrian and cyclist count expansion studies. The land...

Making intersections safer with I2V communication

Intersections are hazardous places. Threats arise from interactions among pedestrians, bicycles and vehicles, more complicated vehicle trajectories in the absence of lane markings, phases that prevent determining who has the right of way, invisible vehicle approaches, vehicle obstructions, and illegal movements. These challenges are not fully addressed by the “road diet” and road redesign prescribed in Vision Zero plans, nor will they be completely overcome by autonomous vehicles with their many sensors and tireless attention to surroundings. Accidents can also occur because drivers,...
