Pedestrian Conspicuity: The Effects Of Retroreflector Placement And Retroreflectivity, Justin Graving

All Theses

One factor that has been causally linked to nighttime pedestrian-vehicle collisions is pedestrians being insufficiently conspicuous to drivers. Pedestrian conspicuity can be enhanced by use of retroreflective material, and this on-road experiment investigated the influence of retroreflector configuration, the coefficient of retroreflection (RsubA) of those retroreflectors, and pedestrian motion on conspicuity. There were two retroreflector configurations, three levels of RsubA, and the test pedestrian either walked or stood in place. Data from 121 participants are reported. The pedestrian was detected by more participants and at greater distances when the pedestrian was walking and wearing retroreflectors on the wrists and ankles …
