Safe Main Street Highways Part II: Analyses of Collisions Involving Pedestrians and Bicyclists in Washington State
This project contributes to the Washington State Strategic Highway Safety Plan, whose goals are to achieve zero road fatality and serious injury by 2030 and to reduce the number of pedestrians and bicyclists involved in motor-vehicle collisions on state highways. The study focused on “main street highways” (MSHs), which are ...
Evaluation of Ultra-Wideband Radio for Improved Pedestrian Safety at Signalized Intersections
As America’s population continues to age, the number of pedestrians with mobility or vision disabilities will increase. The focus of this project was to evaluate ultra-wideband (UWB) radio signaling for the purpose of tracking individuals as they cross an intersection. Working with products from DecaWave, we conducted multiple ...
Guidelines for Pervious Concrete Sidewalks, Parking Lots, and Shared-Use Paths to Improve Driver, Biker, and Pedestrian Safety
The surface frictional properties of pervious concrete (PC) slabs were evaluated by using a British Pendulum Tester (BPT) with two different rubber sliders that represented driver and pedestrian users. The volumetric air content at the finished surface of the slabs was quantified by image analysis to identify any ...
Second Generation Accessible Pedestrian Systems
The Americans with Disabilities Act of 1990 has had a great impact on the implementation of Accessible Pedestrian Systems that target accessible and safety impediments faced by pedestrians with mobility and visual impairments. Intersection geometries are not uniform, and the traffic signal timing varies widely from one ...
A Framework for Improved Safety and Accessibility through Pedestrian Guidance and Navigation
With the changes in America's demographics comes a need to provide improved accommodation of individuals with reduced capabilities. To date, our research has focused upon assistive pedestrian signal technologies for pedestrians with impaired vision. Such individuals must learn to cross complex intersections safely using a ...
