Abstract: The present invention provides a system and method for increasing construction site safety. The present invention reduces the risk of a construction or similar large vehicle or piece of mobile machinery hitting a construction worker. The system uses low-power wireless beacons embedded in a construction worker's hardhat or otherwise on the construction worker's person. The low-power wireless beacon interacts with sensor modules around the construction site, on construction vehicles, on construction equipment, or any other suitable placement known to or conceivable by one of skill in the art. The sensor modules send alert signals to a display accessible to a driver of the vehicle, and/or a foreman on the construction site. While the present invention is discussed herein in the context of construction safety, it should be noted that such a system can be applied to any situation where tracking and alert generation would be beneficial.
