Pittsburgh Buses Get Equipped to Blow Horn
About 150 city buses will be outfitted with an experimental system equipped with a horn, strobe lights and a message board to prevent cars from hitting buses from behind.
The system will activate if a sensor on the back of the bus detects a vehicle approaching too quickly.
“This system can ‘see’ 300 feet behind buses, calculates the speed of an approaching vehicle and determines whether the vehicle can stop in time to avoid a collision,” said Todd Jochem, systems scientist with the Carnegie Mellon Robotics Institute.
The experiment is part of a $2-million, two-year pilot program, funded in part by the Federal Transit Administration.
