You need to quantify the data generated from GPS-enabled ITS devices from two cities: Dhaka and Istanbul. The numbers of GPS-enabled devices in Dhaka and Istanbul are 6,000,000 and 12,754,334, respectively. Assume that the minimum size of a GPS record is 20 bytes. In a typical GPS map-matching process, the GPS data collection rate for one device can be as high as once every 10 s (i.e., 8640 samples per device per day) or as low as once every 2 min (i.e., 720 samples per device per day). Calculate (1) the amount of daily GPS data in GB collected with a high data collection rate and (2) the amount of daily GPS data in GB collected with a low data collection rate. (For storage, 1 GB 5 230bytes). Use the following equation to calculate the daily GPS data:
Daily stored GPS data(GB) 5 Size of a GPS record(GB)
