A passenger boarding bridge provides enclosed tunnel between airport terminal building and a parked aircraft. The passenger boarding bridge allows convenient access from terminal building to the aircraft for passensgers, flight attendants and service staff. The anti-collision system of passenger boarding bridge(PBB) is develped to trace th closest distance between two bridges. Each PBB's anti-collision system trigers alarms as the distance between two PBBs approaches to pre-set safety distance.
This study reviews design criteria for anti-collision system of PBB and conducts field tests to verify the system performance
