Thank you for your interest in our competition.
Regarding the shape of the data (288, 495, 436, 3):
288 is the number of 5-mintues bins per day – basically from 00:00 to 23:55 there are 288 bins.
495, 436 is the size of the data (height, width) and 3 is the number of the channels (volume, speed and heading)
Volume is the number of probe points (capped above and below) recorded in each 100*100 meters grid cell.
Speed is the average speed from the collected probe points in each grid cell.
Heading: Each probe point records the heading direction (values from 0 to 359). The points are binned in four heading directions of North-East (0-90), South-East (90-180), South-West (180-270) and North-West (270-0). The raw heading values [0-359] are mapped to four distinct values of [1,85,170,255] in the order of [NW,NE,SW,SE] and the major heading bin, i.e. the bin with the highest number of points is selected.
I hope this help.
Thanks again for your interest.
