Abstract:
1. A computer-implemented method for determining parking difficulty, the method comprising: receiving, at a processor, a plurality of location tracks for a respective plurality of vehicles, each of the plurality of location tracks comprising a plurality of segments of a geographic area traversed by a respective one of the plurality of vehicles; determining, via the processor, a first index for each of the plurality of location tracks, the first index comprising a comparison of a first group of the plurality of segments and a second group of the plurality of segments of each of the plurality of location tracks; selecting, via the processor, a group of the plurality of location tracks based on the first index; determining, via the processor, a circle event for each of the group of the plurality of location tracks, the circle event corresponding to the traverse of at least one of the plurality of segments by a respective one of the plurality of vehicles; counting, via the processor, a number of circle events that includes a first selected segment of the plurality of segments; and assigning, via the processor of the computer, a parking difficulty index for the first selected segment based on the number of circle events for the selected segment, the parking difficulty index representative of parking difficulty in the first selected segment.
