http://www.geolink.pt/ecmlpkdd2015-challenge/dataset.html

- TRIP_ID: (String) It contains a unique identifier for each trip;
- CALL_TYPE: (char) It identifies the way used to demand this service. It may contain one of three possible values:
    - 'A' if this trip was dispatched from the central;
    - 'B' if this trip was demanded directly to a taxi driver at a specific stand;
    - 'C' otherwise (i.e. a trip demanded on a random street).
- ORIGIN_CALL: (integer) It contains a unique identifier for each phone number which was used to demand, at least, one
 service. It identifies the trip's customer if CALL_TYPE='A'. Otherwise, it assumes a NULL value;
- ORIGIN_STAND: (integer): It contains a unique identifier for the taxi stand. It identifies the starting point of the
 trip if CALL_TYPE='B'. Otherwise, it assumes a NULL value;
- TAXI_ID: (integer): It contains a unique identifier for the taxi driver that performed each trip;
- TIMESTAMP: (integer) Unix Timestamp (in seconds). It identifies the trip's start;
- DAYTYPE: (char) It identifies the daytype of the trip's start. It assumes one of three possible values:
    - 'B' if this trip started on a holiday or any other special day (i.e. extending holidays, floating holidays, etc.);
    - 'C' if the trip started on a day before a type-B day;
    - 'A' otherwise (i.e. a normal day, workday or weekend).

- MISSING_DATA: (Boolean) It is FALSE when the GPS data stream is complete and TRUE whenever one (or more) locations 
are missing;
- POLYLINE: (String): It contains a list of GPS coordinates (i.e. WGS84 format) mapped as a string. The beginning and 
the end of the string are identified with brackets (i.e. [ and ], respectively). Each pair of coordinates is also identified by the same brackets as [LONGITUDE, LATITUDE]. This list contains one pair of coordinates for each 15 seconds of trip. The last list item corresponds to the trip's destination while the first one represents its start;
