TL;DR: A cell phone app that delivered information to texting pedestrians about when traffic conditions permit safe crossing and the potential of assistive technologies based on Vehicle-to-Pedestrian (V2P) communications technology for mitigating pedestrian-motor vehicle crashes is developed.

TL;DR: This investigation compared how people performed a complex perception-action task - crossing traffic-filled roadways - in a CAVE vs. an HMD virtual environment, finding that participants in the Vive group accepted smaller gaps for crossing and had a somewhat larger margin of safety when they exited the roadway.

TL;DR: The results demonstrate the detrimental influence of texting on pedestrians’ gap selection, movement timing, and gaze behavior, and show the potential of warnings to improve decision making and safety, but also reveal the limits of warning texting participants once they initiate a crossing and possible overreliance on technology that may lead to reduced situation awareness.

TL;DR: It is found that pairs often crossed the same gap together and closely synchronized their movements when crossing and chose larger gaps than individuals to accommodate the extra time needed to cross through gaps together.
