Abstract: A system for enhancing personnel safety on a railroad track is presented. The system can receive data from sensors and/or a PTC system to determine positions of clients/worker and/or vehicles, and further utilize such data to determine if a vehicle is within a certain proximity of the client/worker location. The system can further generate geofences around clients/vehicles to and determine when such geofences intersect one another. Additionally, the present disclosure can assign severity levels and generate alerts with the assigned severity levels, and such severity levels can indicate how close a vehicle is to a particular location. It is an object of the invention to provide a system for generating alerts to notify personnel when they much retreat to a place of safety.
