Using VR to measure if pedestrians trust autonomous vehicles


[music] (On-screen text): When do pedestrians feel safe
crossing a street full of autonomous vehicles (AVs)? To find out, University of Michigan researchers
placed participants in a virtual city. In six different scenarios, participants had
to cross a busy street multiple times. There were two different variables: 1) How aggressive the AVs were 2) The presence of a crossing signal Participants had more trust in the less-aggressive
AVs when crossing without a signal. When crossing with a signal, participants had
high levels of trust regardless of driving behavior. This could be a sign of overtrust, meaning pedestrians
might unknowingly engage in risky behavior. The researchers concluded that trust is an important
factor in how pedestrians interact with AVs, and future work needs to examine how
AVs and pedestrians could interact to establish the right amount of trust.
