Abstract:
1. A method using airport surveillance data to output a location of a delay and an amount of time a vehicle is subjected to the delay during a movement of the vehicle between a first location and a second location, the method comprising: obtaining a time-ordered sequence of data points representing the movement of the vehicle, each data point including an (x) position coordinate and a (y) position coordinate, at a particular time represented by a time stamp; creating a vector (v) including a plurality of elements by performing the following steps for each data point (i) in the time ordered sequence, each of the elements corresponding to a respective one of the data points from the time ordered sequence, the steps comprising: replacing all of the number (N) entries in the vector (v) that have a value greater than a predetermined value (K) with a one (1) entry; replacing all of the number (N) entries in the vector (v) that have a value equal to or less than the predetermined value (K) with a zero (0) entry; replacing each zero (0) entry in the vector (v) with a one (1) entry if the zero (0) entry is a part of a sequence of consecutive zero (0) entries, the sequence of consecutive zero entries being less than a predetermined value (S); defining a starting index and a stopping index within the vector (v) for each sequence of consecutive one (1) entries, each of the sequences of consecutive one (1) entries defining a proposed knot (ki); performing the following steps for each proposed knot (ki): eliminating any proposed knots that have less than a predetermined number (d) of data points remaining; identifying the data points associated with any remaining proposed knot as being associated with the respective proposed knot; and saving the data points identified onto a computer readable medium for at least one of review by an individual, production of a graphical display on a computer terminal, and production of a presentation document identifying those data points as being associated with one of the proposed knots.
