# Point of interest facility marking modules and systems and methods of using tiie same

## Abstract

Facility marking modules (FMM) and methods and systems of using the same. A FMM is associated with a point of interest (POI) at a worksite or other facility. The FMM detects a low frequency magnetic field of a vehicle moving within the facility at or near the POI and transmits a response signal to a proximity detection system (PDS) of the vehicle. The response signal can cause an operational alert lo activate, or to slow, stop, or change direction of the vehicle based on traffic restrictions associated with the POI. In some examples, the response signal can be used to generate vehicular traffic data for improving efficiency and/or safety of the facility.
