METHODS AND SYSTEMS FOR TAXIWAY TRAFFIC ALERTING
First Claim
1. A method performed by a system located on an ownship, the method comprising:
- at a processing device,a. receiving information from a ground traffic vehicle;
b. receiving ownship information;
c. determining distance to the ground traffic vehicle will pass the ownship after an estimated full-stop location of the ownship based on the received ownship information and one or more predefined constants; and
d. generating a potential collision alert if the determined distance is less than a predefined safe distance value; and
at an output device, outputting the generated potential collision alert.

Abstract
Systems and methods for providing the crew of an airplane or vehicle with a potential traffic-threat alert. When the alert is triggered is based on presumed flight-crew action and reaction times, ownship speed, and required distance to safely stop the ownship before intersection with traffic. An exemplary system located aboard an ownship includes a communication device that receives information from a ground traffic; a memory device that stores ownship information and predefined constants; and a processing device that determines a distance to the traffic when the traffic passes the ownship after the ownship stops at an estimated full-stop location, based on the received ownship information and the predefined constants, determines distance to the ground traffic vehicle, based on the determined point in time, and generates a potential collision alert if the determined distance is less than a predefined safe distance value. An output device outputs the generated potential collision alert.
