System for securing of safety of railroad crossing against vehicle entry during warning signaling
According the application of the invention when barriers are lowered, first are lowered barrier in front rails after, in adjustable time delay, that barrier behind rails, what allow to vehicles clear out rail area. Sensor advantageously senses area on rails and in case of any obstruction for railway train delays lowering of barriers or stops it till the time when obstruction leaves rails. In the same time it transmits alarm into dispatching of train transport and into coming railway train by means of wireless connection. It simultaneously activates alarm siren and advantageously voice announcement calling for releasing of rails.
METHOD AND SYSTEM FOR SHARING OF INFORMATION PERTINENT AT A RAILWAY CROSSING
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.
RAILROAD CROSSING GATE LAMP SYSTEM
The present disclosure provides a new gate lamp system and method. The system and method is configured to facilitate the installation of a gate lamp onto a gate arm, and to facilitate the replacement of one or more of the gate lamps. The present disclosure provides a system and method of installing gate lamps on a gate arm in the field in a robust manner with ease.
DETECTION OF DYNAMIC TRAIN-TO-RAIL SHUNTING PERFORMANCE
Systems and methods for detecting the dynamic train-to-rail shunting performance of a train as it is moving along the rails of a railroad track. The systems and methods use portable equipment temporarily installed at a site where it is desired to test the shunting of one or more trains or the electrical equipment installed at the track. The systems and method use sensor plates and a high speed recording system to simultaneously capture measured train-to-rail shunting characteristics and the positioning of a train's axles and any rail conditions impacting the measurements. The captured information can be used to fine tune the train, the electrical equipment installed at the track and/or to design new devices.
Intelligent Railroad At-Grade Crossings
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for monitoring vehicles traversing a dedicated roadway that includes an at-grade crossing. In some implementations, a system includes a central server, a gate system, and sensors. The gate system provides access to an at-grade crossing for vehicles. The sensors are positioned in a fixed location relative to a roadway, the roadway including the at-grade crossing. Each sensor can detect vehicles on the roadway. For each vehicle, each sensor can generate sensor data and observational data from the generated sensor data. Each sensor can determine a likelihood that the detected vehicle will approach the at-grade crossing by comparing the likelihood to a threshold. In response, each sensor can transmit data to the gate system that causes the gate system to allow the autonomous vehicle access to the at-grade crossing prior to the autonomous vehicle reaching the gate system.
System and method for real-time detection of trains
Methods and systems for real-time detection and reporting of trains is described. A system includes two train detection units (TDUs) for each railroad track intersecting a municipality boundary. Each TDU including a proximity sensor to sense a presence of an object on the railroad track, a camera to capture an image of a detected object when the object is within a detection zone, a radar to measure speed when the detected object is classified as a train, and a processor to classify the detected object, generate a timestamp corresponding to when the train entered and exited the detection zone, and determine a train length from the speed and time delta between entrance timestamp and exit timestamp. A train detection controller to receive at least the train length and a TDU identification from one of the two TDUs, and determine estimated time of arrivals for the train at different municipality locations.
Detecting the movement of a rail vehicle
A method for detecting a movement of a rail vehicle, in particular a freight or passenger train, in a warning zone of a rail crossing, includes: determining a first temperature in the warning zone of the rail crossing or in a portion of the warning zone at a first time; determining a second temperature in the warning zone of the rail crossing or in a portion of the warning zone at a second time. The first time is chronologically before the second time. The method compares the first temperature with the second temperature. If the comparison demonstrates that the second temperature is higher than the first temperature, the method outputs a warning signal and initiates blocking of the rail crossing.
Wireless crossing warning activation and monitoring
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.
