Method and device for providing traffic information including a prediction of travel time to traverse a link and using the same
First Claim
1. A method for decoding traffic information data, the method comprising:
- receiving, at a receiver, traffic information data in a traffic message, the traffic information data including;
speed information indicating a travel speed across a road-segment from a first location to a second location, and a first identifier for enabling a determination that the speed information is included in the traffic information,predicted speed information indicating a predicted travel speed across the road-segment from the first location to the second location, and a second identifier for enabling a determination that the predicted speed information is included in the traffic information,time information indicating a time with which the predicted speed information corresponds, and a third identifier for enabling a determination that the time information is included in the traffic information, anda congestion tendency value reflective of a congestion tendency of the road-segment from the first location to the second location, and a fourth identifier for enabling a determination that the congestion tendency information is included in the traffic information, wherein the congestion tendency value corresponds to one of multiple values in a congestion tendency table utilized in generating and decoding the traffic information data; and
decoding a status of traffic congestion of the road-segment from the first location to the second location based on the received traffic information data in the traffic message and the congestion tendency table.

Abstract
A method for identifying traffic information includes receiving traffic data including a first identifier, information corresponding to a predicted amount of time to traverse a particular link, and information corresponding to a location associated with the particular link, where the first identifier enables a determination of a type of the information that is included within the received traffic data. The method also includes determining a type of information included within the received traffic data based on the first identifier and determining travel time prediction information based on the predicted amount of time included in the received traffic data only if the first identifier enables a determination that the received traffic data includes a prediction related to an amount of time. The method further includes determining location information based on the information that is included in the received traffic data corresponding to the location associated with the particular link and identifying traffic information based on the determined travel time prediction information and the determined location information.
