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.

A rail network is divided by track elements into track sections on which vehicles can travel. The vehicles request, from selected track elements, steps for assignment as a route element. Each of the selected track elements is respectively automatically assigned as a route element, under predefined conditions, for each vehicle which requests the steps for assignment as a route element to it, and outputs an assignment confirmation to the respective vehicle. For better protection of construction and/or maintenance work in the hazardous area of the rail network at least one of the track elements forms, after its integration into the rail network, a working zone and does not output the assignment confirmation for the respective vehicle until after an assignment release is input. The track element is provided with a release device into which the assignment release is input manually.

A method for 3D positioning in a subway construction site. The method includes: establishing a 3D coordinate system corresponding to a shaft area, and determining a coordinate of each UWB base station set in different layers of the shaft area; ranging a positioning label through each UWB base station; filtering and discarding error data from the ranging data; dividing the 3D coordinate system into a plurality of equal cube grids, selecting a preset number of UWB base stations from the set UWB base stations based on the filtered result, and determining a position record of the positioning label in each cube grid in turn based on coordinates of the selected UWB base stations and corresponding ranging data, and the center point coordinate of each cube grid; and determining a conclusion coordinate of the positioning label by voting based on the position record of each cube grid.

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.

A system includes a safety mode activation device disposed onboard a vehicle system and operatively connected to a controller of the vehicle system. The safety mode activation device is configured to receive a status signal indicating a presence of one or more of an operator or an active work marker in a location proximate to the vehicle system. The safety mode activation device is further configured to transmit a lockout signal to the controller to prevent movement of the vehicle system along a route responsive to receiving the status signal.
