1. A computer-implemented method for visualizing traffic data on a map, comprising:
- receiving a plurality of GPS samples from a plurality of GPS devices, each GPS sample comprising a location, a direction of travel and a speed of travel of a GPS device from which the GPS sample is received;
associating selected GPS samples with respective road segments on a map based on the location and the direction of travel in each selected GPS sample;
determining a direction of travel for a road segment based on a plurality of directions of travel from GPS samples associated with the road segment;
identifying a one-way road based on the determined direction of travel of the road segment; and
generating for display on a map containing a road segment a plurality of representations based on the GPS samples associated with the road segment, each generated representation visually indicating the direction of travel, the one-way road, and the speed of travel for the GPS device that provided a GPS sample.

Abstract
Maps are created that display representations of GPS data generated from a plurality of GPS devices. The GPS data received from the GPS devices is embodied as a representation having descriptive features that visually indicate the location, direction of travel, and speed of travel of the GPS device, and the representation is associated with a road segment on the map. The display of the GPS data from a plurality of GPS devices can be used for editing information about roads on maps and determining preferred routes.
