This study was aimed at filling part of the knowledge gap on bicycling safety in the built environment by addressing two questions. First, are built environment features and bicyclist injury severity correlated, and if so, what built environment factors most significantly relate to severe bicycling injuries? Second, do the ...

There is little research on the behavioral interaction between bicycle lanes and commercial vehicle loading zones in the United States. These interactions are important to understand, to preempt increasing conflicts between truckers and bicyclists. In this study, a bicycling simulator experiment examined bicycle and truck ...

Conflict between bicycles and right-turning vehicles on the approaches to intersections is a critical safety concern in urban environments. To understand the safety and operational implications of using protected-permitted right turns (PPRT), a full-scale bicycling simulator experiment was performed. The velocity and lateral ...

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 ...
