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 a segment proximate to the latitude and longitude of the user and at least one segment incident to the proximate segment;
identifying a segment presently being traversed by the user based on the latitude and longitude of the user in transit, the proximate segment, and a vector of the user in transit, the vector relative to the incident segment; and
publishing indicia of road traffic conditions corresponding to the segment presently being traversed.

6. 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 a segment proximate to the latitude and longitude of the user and at least one segment incident to the proximate segment; identifying a segment presently being traversed by the user based on the latitude and longitude of the user in transit, the proximate segment, and a vector of the user in transit, the vector relative to the 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 (7)
