First Claim
Patent Images
1. A traffic data processing system that creates a virtual representation of a road network that can be queried by multiple traffic reporting applications to obtain traffic data, comprising:
- a first computer that receives and analyzes traffic flow data, wherein the first computer generates a traffic flow data stream with results of the analyzed traffic flow data;
a second computer that receives and analyzes traffic information related to traffic events that can impact traffic flow, wherein the second computer generates traffic items with results of the analyzed traffic information;
a third computer that receives and integrates the traffic flow data stream, the traffic items, and map data representing the road network creating a virtual traffic network representing traffic conditions on the road network, wherein the third computer receives queries from more than one type of traffic reporting applications and, in response to the queries, the third computer provides traffic data to the traffic reporting applications; and
a fourth computer that receives the traffic items from the third computer and creates a plurality of text renditions for each of the traffic items, wherein the fourth computer provides the plurality of text renditions to the third computer, and wherein the third computer selects one of the plurality of text renditions for providing the traffic data to the traffic reporting applications.

12. A computer-implemented method of providing traffic data to a variety of traffic reporting applications, comprising:
-
creating multiple text renditions for a traffic record containing data representing traffic events that can impact traffic flow using a predefined rule set, wherein each text rendition is a string representation of the data in the traffic record; receiving a request for traffic data from a traffic reporting application, wherein the request identifies a format for providing traffic data to the traffic reporting application; retrieving traffic data responsive to the request; and rendering the traffic data in the format that matches the request from the traffic reporting application. - View Dependent Claims (13, 14, 15, 16)

17. A computer-implemented method of providing traffic data to a television station, comprising:
-
receiving map data representing a road network, wherein the map data includes link and node data representing portions of roads in the road network; receiving flow data related to traffic flow on the road network; receiving traffic information about traffic events on the road network; integrating the map data, the flow data, and the traffic information to produce a virtual traffic network representing traffic conditions on the road network, wherein the virtual traffic network includes a graphical layer for a visual representation of the traffic conditions on the road network; receiving a request for traffic data from a television application, wherein the request identifies an area within the road network for obtaining the traffic data; identifying links in the graphical layer for the requested area; obtaining state information for the identified links, wherein the state information is based on the current traffic conditions on the portions of the roads represented by the links; and providing a response to the request from the television application that includes data representing the identified links in the graphical layer and the associated state information. - View Dependent Claims (18, 19, 20)
