Abstract |
Crosswalks are designed to enhance pedestrian visibility and right-of-way. This study examines driver performance at two different crosswalks with different pedestrian signal designs: (1) Rectangular Rapid Flashing Beacons (RRFBs) and (2) Pedestrian Hybrid Beacons (PHB). Mixed effects linear models showed that the drivers' speed significantly decreased when a signal was activated, with a larger decrease observed at a PHB signal when there was no lead vehicle. Mixed effects logistic models showed that drivers' likelihood to change distracting status was higher when a pedestrian signal was activated. The change could occur in both directions: from being engaged to not and from not engaged to distracted. Males and females responded differently to the RRFB in terms of speed differential and likelihood to engage in distractions from an undistracted state. In summary, PHB was able to decrease driver speed more effectively, while RRFB appeared to promote less travel delays for drivers. Language: en |
