Trucks Dataset: The original dataset consists of the GPS-tracked positions of 50 trucks transporting concrete in the area of Athens between August and September 2002. The dataset contains 1,12,300 position records consisting of the truck identifiers, dates and times, and geographical coordinates. The temporal spacing is regular and equals 30 s. From these raw data, it was produced 1,100 trajectories by splitting the recordings of a truck in subsets if there was a temporal gap between two consecutive recordings larger than 15 min (a gap that indicates a stop not due to traffic or traffic lights).
