GPS (Global Positioning System)

collection environment

320 taxi drivers that work in the center of Rome. Traces present the positions of drivers, collected every 7 seconds.

data collection methodology

Each taxi driver has a tablet that periodically (~7s) retrieves the GPS position and sends it to a central server. Tablets have different version of Android and different brand.

sanitization

Driver names have been replaced with an id.

limitation

To retrieve the position, we used the getAccuracy function of Android LocationManager objects. We filter out the positions if their precision is less than 20m.
