====== Private Transportation ====== December-November approximately 3000000 rows for each month The dataset gives information about the private mobility in the city of Milan. The dataset results from aggregation on the data provided by Cobra Telematics Cobra Telematics provides a service to insurance companies to track the cars of their customers via GPS. Insurance companies exploit GPS traces in order to offer additional services to the customers (e.g. satellite antitheft system and localization in case of emergency) and to determine who is responsible for a car accident. This dataset is based on the punctual fine-grained GPS readings collected in the Milan area. The location of a car is recorded every minute (only when the car is turned on) and they are aggregated as follows. Spatial Aggregation: the Milano GRID square and the heading direction (north, east, south, west) of cars. Temporal Aggregation: ten minutes. //Schema:// - **Square id:** the id of the square that is part of the Milano GRID; TYPE: numeric - **Timeslot:** the beginning of the time slot in the format YYYY-MM-dd hh:mm. TYPE: date. - **Direction:** the direction of cars. It can have four values: North, East, South and West: - In some specific cases (e.g. the car is not moving) due to technical limitations the direction of the car is not available. In this case the reading is aggregated under the value none. TYPE: string. - **Average speed:** the average speed of cars located in the Square id i during the Timeslot t heading in the Direction d. TYPE: numeric. - Stdv speed: the standard deviation speed of cars located in the Square id during the Timeslot heading in the Direction. TYPE: numeric. - **Nr of Milan readings:** the number of readings produced by the GPS devices installed in cars with plates registered in the Milan province. The readings are generated in Square id during the Timeslot heading in the Direction. TYPE: numeric - **Nr of non-Milan readings:** the number of readings produced by the GPS devices installed in cars with plates registered outside the Milan province. The readings are generated in Square id during the Timeslot heading in the Direction. TYPE: numeric. - **Nr of ignition car readings:** the number of readings produced by the GPS devices attached to cars just being turned on. The readings are generated in Square id during the Timeslot heading in the Direction. TYPE: numeric. - **Nr of moving car readings:** the number of readings produced by the GPS devices attached to moving cars. The readings are generated in Square id during the Timeslot heading in the Direction. TYPE: numeric. - **Nr of stopped car readings:** the number of readings produced by the GPS devices attached to turned off cars. TYPE: numeric. The readings are generated in Square id during the Timeslot heading in the Direction.
