Can You See Me? Naturalistic Pedestrian and Bicycle Perception in Multimodal Contexts

Abstract

Design standards inherently assume that line of sight will support Vulnerable Road User (VRU) perception. Pedestrian and Bicycle crash histories imply otherwise. A 1-s mid-block epoch was viewed at 200 multimodal sites to determine the driver’s level of multitasking and whether a VRU was seen, missed, or absent, along with contextual features and the 85th percentile speed. VRU’s were infrequently present and more infrequently seen (37% and 20%, respectively). Sidewalk type, building face width, LOS, speed, speed limit, doorway density, and Right of Way width impacted VRU perception. VRU perception impacted the 85th percentile speed and multitasking behavior, which was also impacted by age, city, sidewalk type, and crash history. Workload and human presence impact the relationship between attention and context. VRU presence is impacted by a wide range of contextual features that support walkability.
