System and method for train operation approaching grade crossings

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.

Shallow flangeway rail seal

A rail seal for sealing the gap between a rail and a concrete panel in a railroad crossing so as to provide a generally even or level surface for vehicular or pedestrian traffic while still providing an appropriate rail structure for receiving and guiding the train wheels along the tracks is provided. More particularly, the upper surface of the rail seal is formed with a recessed portion or flangeway for receiving the flanged-end of a train. The flangeway or recessed portion, however, is formed so that the surface of the flangeway lies in a plane above the bottom of the rail head but below the upper surface of the rail head, thereby providing a “shallow” flangeway. The provision of a “shallow” flangeway helps to reduce the risks associated with vehicular and / or other pedestrian traffic that must access or cross the railroad tracks. Specifically, the shallow flangeway helps to prevent the heels of pedestrian shoes or the smaller width bicycle, stroller or wheelchair wheels from becoming trapped in the gaps typically associated with railroad crossing structures.

Asynchronous wireless sensing

Low-complexity asynchronous wireless sensing and communication architecture is disclosed for low power wireless sensors. Schemes are based on asynchronous digital communications and Ultra-Wideband impulse radios. In asynchronous radio, combination of frequency-shift-keying (FSK) and on-off-keying (OOK) to remove clock synchronization is applied. Improved asynchronous non-coherent transmitters and receivers achieve both low power and low complexity while seamlessly combined with asynchronous level-crossing modulation. Both uncoded and coded asynchronous communication may be utilized. Coded asynchronous communication may use error correction. Forward error correction schemes for asynchronous sensor communication are utilized where dominant errors consist of pulse deletions and insertions, and where instantaneous encoding takes place. Forward error correction is also accomplished where a continuous-time sparse waveform signal is asynchronously sampled and communicated over a noisy channel via Q-ary frequency-shift keying. Concatenated code employs outer systematic convolutional codes and inner embedded marker codes that preserve timing information and protect against symbol insertions and deletions.
