    • 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.
    • 一个过路警戒系统,用于保护行人和驾驶人士免受即将到来的火车。 所述警报系统具有车辆检测器系统,用于确定车辆是否卡在所述铁路道口的区域中;列车检测器系统,用于确定包括所述迎面而来的列车的速度和方向的重要列车信息;显示单元,用于显示警告消息 靠近铁路道口的行人和驾驶者,以及用于将重要列车信息和遇险车辆信息传达给迎面而来的列车和显示系统的通信系统。 该系统向即将来临的列车运营人提供预警,为铁路过境处的遇难车辆和靠近铁路道口的驾车人士和行人提供更可靠的保护。

    • 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.
    • 智能交叉控制系统具有内部控制器,该内部控制器接收包含关于例如列车的方向,速度,长度和身份的详细信息项目的数字消息。 控制器产生适当的命令,协调交叉安全装置的功能。 控制器能够接收和使用比常规警告系统可能的更详细的列车信息。 铁路穿越警告功能能够更灵活地响应更详细的火车信息。 控制器还连续调整与穿越相关的安全装置的启动状态。 在具体实施例中,控制系统提供和显示交叉状态信息,包括直到交叉点清除列车交通的剩余时间量,第二列车在阻挡第一列车过道时的接近,或建议的替代路线 等候路车辆。 控制器还可用于致动许多标准的交叉警告功能,包括交叉阻挡臂,闪光灯,警告铃声和警告喇叭。
