PREDICTIVE RAILROAD CROSSING SAFETY NOTIFICATION AND TRAFFIC CONTROL SYSTEM AND METHODS
A predictive railroad crossing system proactively improves railroad safety notification and traffic control decisions to avoid crossing-associated delays for a plurality of operating trains. The system is configured to iteratively respond to real-time operating data for the trains and identify public or private railroad crossings that each respective operating train will approach. An estimated time of arrival and estimated of blocked crossing duration time is made predictively for each of identified public or private railroad crossings without any physical train detection in at least some of the identified public or private railroad crossings.

METHOD AND ARRANGEMENT FOR SECURING A RAILROAD CROSSING
A method secures a railroad crossing which allows a timely securing of the railroad crossing, and is particularly efficient and reliable. The method proceeds in such a way that sensor data relating to a rail-borne vehicle approaching the railroad crossing are detected by a track-side sensor device. The sensor data contains at least the current speed of the rail-borne vehicle. The detected sensor data are transmitted by the track-side sensor device to a stationary control device. A switch-on time is determined by the stationary control device taking into account the transmitted sensor data and route data. Upon reaching the switch-on time, the securing of the railroad crossing is initiated by the stationary control device. After the railroad crossing has been successfully secured, a travel permission that extends beyond the railroad crossing is determined by a control device of a train control system, and is transmitted to the rail-borne vehicle.

TRAIN COLLISION AVOIDANCE AND ALERT
Systems and methods are provided for generating a safety notification to a first train with respect to a speed of a second train along a track, the system including a camera transceiver, comprising a light emitter configured to emit a narrow bandwidth light, an image sensor, one or more light reflectors and a lens subsystem; and a processor configured to perform the steps of: determining a train speed and a train position; receiving images from the camera transceiver; processing the images to calculate a speed and a position of a potential obstacle on the track; responsively to calculating the potential obstacle speed and position, determining a safe speed of the train and providing a control signal to control the first train.

System to provide real-time railroad grade crossing information to support traffic management decision-making
A system that automatically communicates the event or potential event of a blocked railroad grade crossing to various users, including but not limited to emergency dispatchers and drivers, news media, traffic management systems, and the general public, specifically the location, time, and duration of the event or potential event. The system applies multiple technologies to detect the presence of activity on a rail line, transmits this detection data to a database, performs various analyses on the data, and communicates the status of grade crossings (blocked, potentially blocked, upcoming blockage, or clear) to assist various users with information to make more informed decisions.
Method For Securing A Level Crossing, And Stationary Control Device For A Train Control System
A method for securing a level crossing permits timely securing of the level crossing and is particularly effective and reliable. The method proceeds in such a way that vehicle data are received from a track-bound vehicle approaching the level crossing by a stationary control device of a train control system. The vehicle data include at least the current position and the current speed of the track-bound vehicle. A strike-in point is determined on the basis of the received vehicle data and route data including at least the location of the level crossing. Securing of the level crossing is triggered when the strike-in point is reached. A stationary control device for a train control system and an arrangement having such a stationary control device are also provided.
Connected vehicle traffic safety system and a method of predicting and avoiding crashes at railroad grade crossings
A connected vehicle train-vehicle collision detection system comprises a roadside unit (RSU) located at a railroad grade crossing near a roadway lane for avoiding TRAIN crashes with Onboard Unit (OBU)-equipped vehicles by issuing advance warnings for a potential vehicle-train crash. The roadside unit (RSU) is configured to act as a proxy Onboard Unit (OBU) for a non-OBU-equipped TRAIN and transmit a train location to a first Onboard Unit (OBU)-equipped vehicle having an Onboard Unit (OBU). The Onboard Unit (OBU) of the first OBU-equipped vehicle is configured to calculate a train-vehicle crash based on the train location of the TRAIN relative to the railroad grade crossing and a vehicle location of the first OBU-equipped vehicle relative to the railroad grade crossing.
