Patent Images
1. A method for disseminating road traffic information, the method comprising:
- receiving a latitude and longitude of a user in transit;
accessing a segment database to acquire segment information including segment latitude and longitude information for a plurality of segments, the plurality of segments including the segment closest to the latitude and longitude of the user and at least one incident segment;
identifying a segment presently being traversed by the user based on the latitude and longitude of the user in transit and a vector of the user in transit, the vector relative to the at least one incident segment; and
publishing indicia of road traffic conditions corresponding to the segment presently being traversed.

6. A system for disseminating road traffic information, comprising:
-
a plurality of data sources configured to provide traffic data;
a data processing engine configured to generate quality traffic data, the quality traffic data based on the traffic data from the plurality of data sources, wherein the quality traffic data is as complete and timely as is presently available; and
a publishing engine configured to generate a traffic report based on the quality traffic data, wherein the traffic report includes traffic area images of a particular traffic area and a plurality of computer-generated traffic route images that follow the natural path of real-world traffic routes in the particular traffic area, the plurality of computer-generated traffic route images overlaid on the traffic area images. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A computer-readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for disseminating road traffic information, the method comprising:
-
receiving a latitude and longitude of a user in transit, wherein the latitude and longitude of the user in transit is generated by a global positioning system (GPS) compatible transceiver or is based on time difference of arrival between base stations in a cellular network;
accessing a segment database to acquire segment information including segment latitude and longitude information for a plurality of segments, the plurality of segments including the segment closest to the latitude and longitude of the user and at least one incident segment;
identifying a segment presently being traversed by the user based on the latitude and longitude of the user in transit and a vector of the user in transit, the vector relative to the at least one incident segment; and
publishing indicia of road traffic conditions corresponding to the segment presently being traversed, wherein the indicia of road traffic conditions include graphical icons representing specific types of incidents in a particular traffic area. - View Dependent Claims (25)
