Modern roundabouts have become very popular in North America over the last decade. This popularity can be attributed to their great success in Europe and Australia. The prevalence of roundabouts has generated significant debate over their accessibility for pedestrians. With almost uninterrupted traffic flows, it is difficult for the visually impaired to determine safe gaps relying on auditory c...
BACKGROUND The association between distraction caused by cell phone use while driving and driver/passenger fatalities has been documented, but the safety risks associated with headphone use by pedestrians remains unknown. OBJECTIVE To identify and describe pedestrian-vehicle crashes in which the pedestrian was using headphones. METHODS A retrospective case series was conducted by searching ...

Although crosswalks and signs inform pedestrians where to cross, there is no standard protocol for pedestrians to signal drivers that they wish to use the crosswalks, except to stand in or at the crosswalk. We examined the effects of two pedestrian prompts, a raised hand and extended arm, on ...
Automated Pedestrian Safety Analysis Using Video Data in the Context of Scramble Phase Intersections

There has been a traditional shortcoming in the transportation literature with regard to the availability of and quality of pedestrian data. A potential reason is that current data collection methods mainly rely on human observers which make them costly and prone to observer-based errors. In ad...

Intelligent speed adaption (ISA) is one type of vehicle-based intelligent transportation systems (ITS), which warns and regulates driving speed according to the speed limits of the roads. Early field studies showed that ISA could reduce general mean speed levels and their variances in different road environments. This paper studies the effects of various ISA penetration grades on pedestrian saf...
