A recently granted patent (Publication Number: US11866077B2) outlines a method and system for enhancing rail worker safety within a work zone. The method involves defining geographical boundaries within the work zone, receiving the location of a rail vehicle at a control center, and transmitting warning signals to the rail vehicle based on its proximity to these boundaries. The system is designed to activate alarms in response to specific distances between the rail vehicle and the boundaries, independent of the vehicle's speed, ensuring timely alerts to prevent potential accidents.

Furthermore, the patent details a railway safety system comprising communication devices, vehicle units, and alarm systems to ensure comprehensive safety measures. The system includes features such as location determination units, transceivers, and alarm units to generate audio or visual alarms based on predefined threshold distances from geographical boundaries. Additionally, the system incorporates mechanisms for rail workers to receive alerts and acknowledge alarms, enhancing overall safety protocols within the work zone. By utilizing advanced technology and real-time data transmission, this system aims to minimize risks and improve safety standards for rail workers and vehicles operating within the defined boundaries of the work zone.
