Abstract: The present invention provides a system for preventing an accident that minimizes the number of monitor devices and prevents a collision accident to reduce the work and cost burdens. The system for preventing an accident 1 of the present invention includes an imaging device 10, a monitor server 20, and a warning device 60. The control unit 30 of the monitor server 20 executes the area receiving module 31 to receive input of an approach area as an area where a vehicle approaches and a danger area where is danger from an approaching vehicle based on a base image taken by the imaging device 10. The control unit 30 executes the first judgment module 33 to judge whether or not a vehicle enters the approach area based on an image taken by the imaging device 10. If a vehicle enters the approach area, the control unit 30 executes the second judgment module 34 to judge whether or not a person, etc., enters the approach area or the danger area. If a person, etc.

The control unit 30 executes the time period judgment module 33 to judge whether or not it is a time period when a vehicle enters the approach area. If a vehicle enters the approach area, the control unit 30 executes the second judgment module 35 to judge whether or not a person, etc., enters the approach area or the danger area. If a person, etc.

Abstract: There is provided a track current suppression device. An exemplary device includes an input coupled between rails of a railway track and configured to receive an input voltage corresponding to a track current. The exemplary device also includes an amplifier configured to receive the input voltage and generate a cancellation current. The exemplary device also includes an output coupled between the rails of the railway track and configured to deliver the cancellation current to the rails with reversed polarity compared to the track current.

Abstract: A system and method that enables trains to rapidly accelerate through grade crossings from station stops or civil speed restrictions is disclosed. In some embodiments, equipped trains and grade-crossing controllers communicate wirelessly to address operational limitations pertaining to the grade crossings. In conjunction with the train's equipment, conventional crossing controllers are augmented with a communications capability and logic to accept commands to operate in a “Prediction” mode or a “Motion-Sensing” mode. The Prediction mode is the default operating mode for conventional constant-warning grade-crossing prediction controllers. The Motion-Sensing mode is an operating mode whereby the crossing is actuated as soon as an approach circuit detects train motion.

Abstract: A method and a device for diagnosis and state monitoring of a wear and functional state of a junction, a crossing, a crossroads, rail joints, and/or track nonuniformities of a rail traffic path made of several tracks measures and stores swing acceleration in at least one direction when overtaking a rail vehicle on a junction, crossings or crossroads, in addition to rail joints or track nonuniformities on at least one rail vehicle component, the swing acceleration being produced on the rail vehicle component when overtaking the rail vehicle at the junction, crossing or crossroads, rail joints, track nonuniformites. The method also measures and stores the rail vehicle speed and determines and stores the travel direction and the place of the junction, crossing or crossroads, rail joints, track nonuniformities, carries out a control as to whether characteristic, predetermined threshold values of the measured swing accelerations have been exceeded.

Abstract: Sections of a highway crossing over the rail road are raised completely clear of the rail road to form a barrier preventing automobile traffic from entering the rail road when a train is at or nearing the crossing. When the train has passed, the barrier sections are lowered, reforming the grade crossing so that automobile traffic may cross the rail road at near grade. The ends of each barrier transverse to the centerline of the roadway are shaped and positioned so that a continuous surface is formed when the barrier sections are in the lowered position, partly resting on the rail road or nearby supports, allowing automobiles to continue over the rail road by means of driving on the upper surfaces of the lowered barriers, with only small gaps at the joints where the sections adjoin each other or meet the approach roadway.
