Abstract: A warning system comprising an advanced preemption system is provided to provide warning of an additional advanced preemption time directly from a wayside inspector to a city traffic controller to turn one or more traffic lights red on a route intersecting with the railroad crossing. The advanced preemption system includes a first set of wireless magnetometers to be installed on a railway track of the railroad crossing on a first side of the railroad crossing. The first set of wireless magnetometers to be located at an advanced preemption crossing start activation point that is being at a distance before an existing crossing start activation point of the railroad crossing to provide the warning of the additional advanced preemption time.

Abstract: Controlling a level crossing includes one or more transceivers located in proximity of a level crossing area on a first side of a railway track; corresponding passive reflective targets located in proximity of the level crossing area on a second side of the railway track opposite to the first side where each transceiver is located and a control unit connected to each transceiver. Each target is arranged to receive RF signals coming from each transceiver and to send back corresponding reflected signals. Each transceiver is arranged to elaborate said reflected signals to calculate predetermined parameters values. Also, the control unit is arranged to acquire said parameters values from each transceiver and to elaborate them to detect the presence of a train in an area around the level crossing area and, in case of presence of said train, to send a warning message and/or close bars of the level crossing.

Abstract: 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.

Abstract: A method operates a railway safety system having at least one trackside device while taking into account a measured velocity value recorded when the rail vehicle drives into a switch-on section of the railway safety system. In order to minimize the closing times for a level crossing by such a method, the measured velocity value is used as the basis for checking whether a correction time for forwarding a signal from the one trackside device to an associated railway safety assembly is to be set according to the measured velocity value when the rail vehicle drives into the switch-on section. Thereafter, a set correction time is checked to determine if the set correction time should remain effective according to at least one further influencing variable of the rail vehicle that determines the travel time. A railway safety system for carrying out the method is also provided.

Abstract: A system includes a determination module and a communication module. The determination module is configured to be located onboard a first vehicle configured to travel along a first route including a crossing corresponding to an intersection of the first route with a second route. The determination module is configured to be communicatively coupled with a remote crossing module. The determination module is configured to determine, based on a speed of the first vehicle, timing information corresponding to a time at which the first vehicle will travel proximate to the crossing on the first route. The communication module is configured to transmit the timing information to the remote crossing module. The timing information includes a reference time configured as an absolute time corresponding to a time for impeding travel of a second vehicle along the second route through the crossing.

Abstract: A train equipped with an onboard system for determining its position and a track database for determining the positions of upcoming grade crossings sends activate after expiration messages to control wayside warning systems at the crossings to achieve a constant warning time while maintaining a safety margin that ensures the train can be stopped if the wayside systems do not respond correctly to the activate after expiration messages. The system may be used in place of existing track-based crossing warning system control circuits. Communications between the train may be radio-based, and may be direct between the train and wayside devices or may be routed through a central station, which may act as a relay or maintain a database. The train may control multiple crossings at one time, thereby eliminating the need for downstream adjacent crossing control.
