GPS trajectory

The GPS track data comes from the open datasets provided by Open ITS Open Alliance, and two open datasets provided by this organization are used in the experiment. The GPS track dataset1 was collected from the experimental road near Zhongshan University in Guangzhou, China, and dataset2 is located in the north-central region of Dongguan, China. The original GPS data contains several sampling frequencies (time intervals), from 10s - 360s. The city road network data used in the experiment is derived from the wiki map of the open-source project OSM.
