Abstract

A railroad-crossing warning system for protecting pedestrians and motorists from an oncoming train. The warning system has a vehicle detector system for determining whether a vehicle is stuck in an area of the railroad crossing, a train detector system for determining vital train information including the speed and direction of the oncoming train, a display unit for displaying warning messages to the pedestrians and motorists approaching the railroad crossing, and a communication system for communicating the vital train information and the distressed vehicle information to the oncoming train and the display system. The system provides early warning to the operator of the oncoming train to provide more reliable protection for distressed vehicles in the railroad crossing and for motorists and pedestrians approaching the railroad crossing.
