Abstract
Embodiments are directed to a system and method for ingesting location event data and identifying a journey for a vehicle from the event data. The journey identification includes identifying whether a given vehicle is moving for purposes of driving to a journey destination.
Claims26
A system comprising a memory including program instructions and a processor configured to execute the instructions for the method, the method comprising:
- ingesting location event data, wherein the location event data is anonymized;
- geohashing locations of the location event data to obtain geohashed locations that each has a precision that uniquely correlates the location event data to a vehicle;
- and
- identifying a journey for the vehicle from the location event data, wherein the journey identification comprises tracking movement as indicated by the geohashed locations over a period of time to determine a journey segment for the journey for the vehicle.
A system comprising a memory including program instructions and a processor configured to execute the instructions for the method, the method comprising:
- ingesting a plurality of anonymized location event data entries, wherein each of the plurality of anonymized location event data entries specifies a location and an event without information identifying any single vehicle;
- geohashing the location of each of the plurality of location event data entries to obtain a geohashed location having a precision that uniquely correlates the event of the location event data entry to a first vehicle;
- identifying a first journey segment for the first vehicle from the plurality of location event data entries;
- identifying a second journey segment for the first vehicle from the plurality of location event data entries, wherein the identification of the first and second journey segments comprises tracking movement as indicated by the geohashed locations over a period of time;
- and
- determining a journey for the first vehicle, wherein the journey incudes the first journey segment and the second journey segment.
A system comprising a memory including program instructions and a processor configured to execute the instructions for the method, the method comprising:
- ingesting a plurality of anonymized location event data entries, wherein each of the plurality of anonymized location event data entries specifies a location and an event without information identifying any single vehicle;
- geohashing the location of each of the plurality of location event data entries to obtain a geohashed location having a precision that uniquely correlates the event of the location event data entry to a first vehicle;
- and
- identifying a vehicle path from the plurality of events tracking movement as indicated by the geohashed locations over a period of time, the identification comprising using a connected components algorithm in which a node represents the geohashed location.
