Enhanced transit location systems and methods are provided. A method comprises receiving, into a vehicle radio located on a vehicle traveling along a roadway, signals transmitted by wayside radios located along the roadway; and determining a location of the vehicle along the roadway based on the received signals.

A system, comprising: a plurality of wayside devices positioned along a train track, the plurality of wayside devices having known positions, each of the plurality of wayside devices comprising at least one first radio-frequency (RF) antenna; a work zone device positioned along the train track, the work zone device comprising at least one second RF antenna configured to transmit RF signals to and/or receive RF signals from the plurality of wayside devices; and at least one processor configured to determine a position of the work zone device using the known positions and using RF signals transmitted between the work zone device and the plurality of wayside devices.

System and methods are provided for warning a worker of a rail vehicle, or an operator of the rail vehicle of the worker. The system includes a worker device, a vehicle device, and a central server. The devices and server operate on one or a combination of actual or simulated satellite navigational signals, and beacon signals to determine the position of the devices, to generate a warning. The position determination may prioritize beacon signals over satellite navigation signals. The position determination may involve correcting a calculated position based on a measured power level of the beacon signal received from the beacon transmitter, an elapsed time since a previous beacon signal was last received by the device from the beacon transmitter, an elapsed time since a previous satellite navigation signal was received by the device, or an accuracy of the position of the device based on the satellite navigation signal.

Systems and methods are provided for worker protection. A safety vest may be configured to support worker protection receiver function in worker protection systems. Components used in conjunction with the receiver functions may be integrated into the safety vest. The components may include one or more antennas, radio receiver (or transceiver) circuitry, integrated power supply source, indication components, and acknowledgement components. The safety vest may generate safety alerts in response to receiving signals from peer transmitter devices in the worker protection systems.

The present disclosure relates to a railway collision protection and safety system having a vehicle device located on rail vehicles at a work zone, a personal protection unit located with rail workers at the work zone, and a dispatcher processor at a control center. An authority limit within the work zone may be determined by the dispatcher processor, and an authority exceeded signal is sent to the rail vehicle when the rail vehicle is determined to exceed the authority limit.
