System and method for railroad personnel safety assurance
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.

a forecasting module configured to use position data to forecast a position of a vehicle on a railroad track;
a proximity detection module configured to determine when one or more railroad constituents are within a particular proximity of one another; and
an interference detection module configured to detect when a first geofence intersects with a second geofence, wherein sizes of the first and second geofences are generated based on a type of the railroad constituents.
14. The system of claim 13 , wherein the forecasting module receives position data and track data to forecast where a vehicle can be at a particular time.
15. The system of claim 13 , wherein the forecasting module uses speed limits, closures, train schedules, maintenance projects, maintenance schedules, to forecast future railroad constituent positions or locations.
16. The system of claim 13 , wherein the proximity detection module is configured to determine a track distance between railroad constituents.
17. The system of claim 16 , wherein the track distance is used to determine whether a proximity threshold is satisfied.
