Abstract
The present inventions provide a system and method for providing a warning using at least one wireless communication link between an approaching object and the location where a warning is to be given based in part on the location of the object and its proximity to the warning location. One aspect of the inventions includes receiving a communication from an object, for example a vehicle, which includes location information, at an alert node, wirelessly communicating alert information to a warning node, and causing a warning device to generate a warning. Preferably the alert node communicates with a plurality of vehicles and a plurality of warning nodes and determines to which of the plurality of warning nodes to communicate alert information based in part on the location information received from at least one of the vehicles and the location of the warning device.
