Sharing the road with driverless cars

Driverless cars, also known as robotaxis or autonomous vehicles, present unique communication challenges for pedestrians, cyclists, and runners who rely on human cues like eye contact and hand waving to negotiate road safety. Professor Stephen Brewster from Glasgow University addresses these concerns by testing visual signals, such as animations for pedestrians and fixed colored light rings for faster-moving road users who only have time for a brief glance. Cultural differences also impact the integration of this technology; for instance, South Korea’s strict laws against jaywalking create a more predictable environment for autonomous systems compared to the United Kingdom. While Phoenix, Arizona, became the first city to deploy fully driverless taxis in 2017, upcoming trials in London will further test how these vehicles interact with diverse urban behaviors and infrastructure. Success depends on replacing traditional human-to-human gestures with standardized technological alerts that ensure safety for all road participants.
