摘要： This disclosure is generally directed to systems and methods for determining a passage status of a train through a railroad crossing. In an example method, a railroad crossing status detector system provided in a vehicle may determine that a train is approaching the railroad crossing. The determination is made by evaluating a first detection signal received from a first train detection apparatus located on one side of the railroad crossing. The railroad crossing status detector system may then evaluate a second detection signal received from a second train detection apparatus located on the other side of the railroad crossing and determine that the train has traveled past the railroad crossing. The system may also evaluate one or both detection signals to determine whether the train is currently located at the railroad crossing or is backing up after traveling at least partway across the railroad crossing.

摘要： A vehicle advisory system and method determine whether a vehicle system moving along a route is within a designated distance of a feature of interest, initiate a distance-based alert sequence of an advisory device of the vehicle system in response to determining that the vehicle system is at or within the designated distance of the feature of interest, and generate advisory signals using the advisory device according to the distance-based alert sequence. The advisory signals are indicative of passage of the vehicle system by the feature of interest during the distance-based alert sequence. The distance-based alert sequence dictates one or more of plural different commencement locations or commencement distances at which advisory signals are generated by the advisory device. The distance-based alert sequence also dictates one or more of plural different termination locations or termination distances where generation of the advisory signals by the advisory device is terminated.

摘要： An information sharing system derives from a roadway vehicles management system position-related data of a roadway vehicle along a road and determines a roadway vehicle timing at or during which the roadway vehicle is estimated to arrive at or cross a railway crossing. The information sharing system further derives from a railway vehicles management system position-related data of a railway vehicle along the railway and determines a railway vehicle timing at or during which the railway vehicle is estimated to arrive at or have passed the railway crossing. The information sharing system determines, based on comparing a roadway vehicle time window to a railway vehicle time window, that the roadway vehicle time window and the railway vehicle time window at least partly overlap. The information sharing system provides information associated with the overlap to the roadway vehicle or the railway vehicle.

摘要： A system for reliable detection of an approaching train and warning the roadway workers in proximity of the track is described. The system comprises at least one train detector cone (TDC) deployed along a side of an active railroad track and one or more personnel warning cones (PWC) placed near the work site, the cones configured in a wireless mesh network to provide redundant communication links. Detection of a train by the train detector cone is transmitted to the personnel warning cones which provide audible and visual warnings to nearby roadway workers. The system also includes a remote server for centralized tracking and monitoring of the train detector cones and personnel warning cones.

摘要： A communication system may wirelessly receive. A crossing controller may check the message to determine whether the message is a valid vital communication. In response to determining the message is the valid vital communication, the crossing controller may deactivate at least one crossing traffic control element. While the at least one crossing traffic control element is deactivated, the crossing controller may activate the at least one crossing traffic control element in response to receiving a command to activate the at least one crossing traffic control element at the communication system. In response to determining the message is not the valid vital communication, the crossing controller may activate the at least one crossing traffic control element.

摘要： A circuit arrangement for revealing light signal errors, in particular for railway safety systems, includes an electronic signal generator, which can be disconnected in a reversible manner in the event of an error, and a control part, configured for incandescent lamps, for controlling and monitoring the signal generator. The device for revealing errors includes an error differentiator between the line-related interference voltage and error of the signal generator. The reliability of the error differentiation is improved and rendered independent of capacitive intermediate energy storage devices, in that the signal generator is connected to a resistance arrangement such that the signal generator voltage is greater, in high-resistance signal generators, than an interference voltage.

摘要： A railroad collision avoidance system and method are disclosed that utilize impulse radio technology to effectively warn a person when there is a locomotive in their vicinity. In one embodiment, the railroad collision avoidance system includes a transmitting impulse radio unit coupled to a locomotive and a receiving impulse radio unit coupled to a vehicle. The transmitting impulse radio unit operates to transmit an impulse radio signal towards the vehicle when the locomotive is a predetermined distance from a railroad crossing. Upon receiving the impulse radio signal, the receiving impulse radio unit makes sure the person operating the vehicle is informed about the potentially dangerous situation. Several embodiments of the railroad collision avoidance system and method are disclosed all of which operate to warn a person when there is a locomotive in their vicinity.

摘要： With the vehicle anti-collision system of the present invention, road vehicles in the vicinity of a railway crossing are alerted as a train approaches the crossing. A signalling device operating in conjunction with a GPS receiver located in the train emits a signal to a receiver located at the railway crossing to provide an indication of the rail vehicle's location with respect to the railway crossing. The signal is sent continuously at predetermined intervals to provide the railway crossing with sufficient data to estimate the velocity and time of arrival of the train or railway vehicle at the crossing. The railway crossing processes the information and transmits an alarm signal to approaching road vehicles as the rail vehicle approaches the crossing. The signal emitted by the crossing is received at the road vehicle which provides various levels of alarms depending on how close the rail vehicle is to the crossing. The communications between the railroad vehicle and the crossing monitor are preferably by satellite link. A sensor is also preferably provided at the crossing to detect an object on the crossing when the rail vehicle is approaching.
