    摘要： 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.

    摘要： A system for controlling a train's approach on a right-of-way to a grade crossing such that a uniform warning time is ensured comprising: a communication based train control scheme including a computer situated on the train; means for detecting the presence of the train at a first control point on the right-of-way and for determining the train's speed thereat; means for activating the gate at the grade crossing responsive to the train being at a second control point on the right-of-way wherein the second control point is based on the determined speed such that a uniform warning time is provided.

    摘要： A railroad crossing light detector system is disclosed. The system includes determining a first signal indicative of the amount of light emitted from an illuminated railroad crossing light source and determining a second signal indicative of the orientation of the crossing light. The first and second signals are transmitted to a signal determination module that compares the first and second signals to predetermined stored values. The compared signals are then provided to a railroad crossing controller for relaying to a central/remote monitoring location. In the event that at least one of the signals is out of range relative to the stored value, then an inspection request signal together with information on the location of the crossing light is provided to the central monitoring location. In this manner, the number of in-person inspections to the crossing light may be significantly reduced.

    摘要： An intelligent intersection control system features an internal controller that receives digital messages containing detailed information items concerning, for example, the direction, speed, length and identity of a train. The controller generates appropriate commands that coordinate the functions of crossing safety devices. A controller is capable of receiving and using much more detailed train information than is possible with conventional warning systems. Railroad crossing warning features are capable of responding more flexibly to this more detailed train information. The controller also continuously adjusts the activation state for safety devices associated with the crossing. In particular embodiments, the control system provides and displays crossing status information including the amount of time remaining until a crossing is cleared of train traffic, the approach of a second train during blocking of the crossing by a first train, or a suggested alternate route for waiting road vehicles. The controller may also be used to actuate numerous standard crossing warning features, including crossing blocking arms, flashing lights, warning chimes and warning horns.
