Generating vehicle traffic data from raw location data for mobile units
First Claim
Patent Images
1. A method for gathering vehicular traffic data based upon location data for one or more mobile units, the method comprising:
- generating vehicle traffic data representing a position of one or more vehicles based on raw location data representing a position of the one or more mobile units;
wherein the generating step further includes,deriving speed data for the mobile units based upon the raw location data, respectively, andfiltering, based upon the speed data, to discriminate which of the mobile units represent vehicles.

Abstract
Where raw location data representing a position of the one or more mobile units is available, vehicular traffic data representing a position of one or more vehicles can be generated based on the raw location for the one or more mobile units. Such generation of vehicular traffic data can include speed-based filtering and/or position-based filtering of the raw location data.

19. A method for gathering vehicular traffic data based upon location data for one or more mobile units, the method comprising:
-
generating vehicle traffic data representing a position of one or more vehicles based on raw location data representing a position of the one or more mobile units, wherein the raw location data for a mobile unit includes an identifier of the mobile unit, position coordinates, and a time stamp indicating when the coordinates were determined, and the traffic data for a vehicle includes an identifier of the vehicle, position coordinates for at least one position, and at least one time stamp corresponding to the position coordinates, respectively. - View Dependent Claims (20)

21. A method for gathering vehicular traffic data based upon location data for one or more mobile units, the method comprising:
-
receiving raw location data representing a position of the one or more mobile units; filtering the raw location data to discriminate which of the mobile units represent vehicles, the filtering being based upon at least one of the following criteria speed data as derived from the raw location data for the mobile units, positions of the mobile units represented by the raw location data, and distances-moved as derived from the raw location data for the mobile units; and generating vehicular traffic data, for each mobile unit identified as a vehicle according to the filtering step, by assigning an identifier of the vehicle, and adopting, as vehicle data, at least the position coordinates and time stamps, respectively, of the mobile unit as position coordinates and time stamps for the vehicle.
