Abstract:

Pedestrians and bicyclists face challenges navigating intersections safely. Limited lines of sight and blind spots can make detecting pedestrians difficult for drivers and automated vehicles; each year, pedestrians and bicyclists account for roughly 20 percent of all traffic fatalities. Because pedestrians and bicyclists are especially at risk for fatalities and serious injuries, improving their safety at intersections is key to ensuring that roadways are safe for all road users. CDA and cooperative perception (CP) technologies are improving the safety of pedestrians and bicyclists at signalized intersections. CP can help drivers and automated vehicles perceive all road users and obstacles on the road by sharing location data based on measurements from sensors of other vehicles and the roadside. The vehicles can then assess whether the pedestrian or bicyclist poses a potential hazard and, if necessary, warn the driver or take automated action to help avoid a collision. For example, a roadside sensor can detect a pedestrian in a crosswalk and send a message to nearby vehicles, alerting them to the pedestrian’s presence.
