GPS-generated traffic information
View Patent ↗Disclosed herein is a traveler information monitoring and dissemination system. The system disclosed herein provides real time information to a traveler, wherein the real time information may be pre-selected by the traveler. The system ensures consistent and quality data are produced and issued to the traveler.
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.
2. The method of claim 1 , wherein the latitude and longitude of the user in transit is generated by a global positioning system (GPS) compatible transceiver, and the indicia of road traffic conditions are published via a display interface coupled to the GPS transceiver.
3. The method of claim 1 , wherein the latitude and longitude of the user in transit is generated based on time difference of arrival between base stations in a cellular network, and the indicia of road traffic conditions are published via a display interface coupled to a mobile device accessing the cellular network.
4. The method of claim 1 , wherein the indicia of road traffic conditions include graphical icons representing specific types of incidents in a particular traffic area, the indicia of road traffic conditions published via a display interface.
5. The method of claim 1 , further comprising formatting the indicia of road traffic conditions for display on a mobile device, the indicia of road traffic conditions published via a display interface at the mobile device.
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.
7. The computer-readable storage medium of claim 6 , wherein the method further comprises formatting the indicia of road traffic conditions for display on a mobile device.
