This disclosure relates to providing information reflecting traffic congestion tendency and using the same.
In one general aspect, a method for identifying traffic information is provided. The method includes receiving traffic data including a first identifier, information corresponding to a prediction of congestion tendency for a particular link, and information corresponding to a location associated with the particular link. The first identifier enables a determination of a type of the information that is included within the received traffic data. The method includes determining a type of information included within the received traffic data based on the first identifier and determining congestion tendency prediction information based on the information included in the received traffic data only if the first identifier enables a determination that the received traffic data includes a prediction related to a congestion tendency. The method 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 congestion tendency prediction information and the determined location information.
Implementations may include one or more additional features. For instance, determining congestion tendency prediction information may include accessing received data reflecting, among other items, results of measurements made with respect to traffic previously traversing the link, and computing a prediction for future congestion based on the received data. Determining congestion tendency prediction information may involve accessing information provided within the received traffic data and recognizing that data as the predicted congestion tendency.
The method may include receiving information corresponding to a message management structure including information corresponding to a generation time of information reflected in the traffic data. The generation time included within the received message management structure may relate to a plurality of message component structures that correspond to more than one of a predicted or current traffic tendency, a predicted or current amount of traffic, a predicted or current speed, or a predicted or current time to traverse a particular link. Each message component structure may further include an identifier specific to the type of information and the first identifier may be an identifier, in a message component structure, specific to the prediction of congestion tendency for the particular link. Information corresponding to a chronological indication associated with the predicted congestion tendency revealed by the received information may be received. The chronological indication may reflect a particular time of day for which the predicted congestion tendency corresponds. The chronological indication may be reflected using the universal time co-ordinated standard.
In the method, the congestion tendency prediction information and the location information may be determined in a single step. The location information may be determined before the congestion tendency prediction information is determined. Receiving traffic data may include decoding the traffic data such that the received traffic data is decoded traffic data.
Also, in the method, receiving information corresponding to a prediction of congestion tendency may include receiving a value associated with a level of congestion. Receiving a value associated with a level of congestion may include receiving a predicted congestion tendency of the link including a text descriptor of congestion and a value associated with a level of congestion. The value associated with a level of congestion may be a code that directs access of a table of values to retrieve a specific value. The value associated with a level of congestion may be determined by a weighted summation of past or present congestion information.
Further, in the method, the information corresponding to a prediction of congestion tendency for a particular link may reflect the predicted congestion tendency.
In another general aspect, an apparatus for identifying traffic information is provided. The apparatus includes an interface configured to receive traffic data including a first identifier, information corresponding to a prediction of congestion tendency for a particular link, and information corresponding to a location associated with the particular link. The first identifier enables a determination of a type of the information that is included within the received traffic data. The apparatus also includes a processor configured to determine a type of information included within the received traffic data based on the first identifier and dependent upon whether the first identifier enables a determination that the received traffic data includes a prediction related to a congestion tendency, determine congestion tendency prediction information based on the information included in the received traffic data. The processor is also configured to determine location information based on the information that is included in the received traffic data corresponding to the location corresponding to the particular link and identify traffic information based on the determined congestion tendency prediction information and the determined location information.
Implementations may include one or more additional features. For instance, the processor may be configured to receive traffic data including information corresponding to a version number of information reflected in the traffic data. The version number may be associated with a specific syntax of the data where any one of multiple syntaxes may be used. The processor may be configured to receive information corresponding to a message management structure including information corresponding to a generation time of information reflected in the traffic data.
In the apparatus, the processor may be configured to receive information corresponding to a data length of the received data. The processor may be configured to receive the predicted congestion tendency reflected as one value in a set of possible values.
Also, in the apparatus, the processor may be further configured to determine the prediction of congestion tendency for a particular link only if the first identifier reveals that the traffic data relates to a prediction of congestion tendency for a particular link.
Further, in another general aspect, an apparatus for identifying traffic information is provided. The apparatus includes means for an interface configured to receive traffic data including a first identifier, information corresponding to a prediction of congestion tendency for a particular link, and information corresponding to a location associated with the particular link. The first identifier enables a determination of a type of the information that is included within the received traffic data. The apparatus also includes means for determining a type of information included within the received traffic data based on the first identifier and means for determining congestion tendency prediction information based on the information included in the received traffic data only if the first identifier enables a determination that the received traffic data includes a prediction related to a congestion tendency. The apparatus further includes means for determining location information based on the information that is included in the received traffic data corresponding to the location corresponding to the particular link and means for identifying traffic information based on the determined congestion tendency prediction information and the determined location information.
A CTT event container 22 may be composed of one component or a plurality of CTT components. In various implementations, CTT components including an ID of 80h (notation ‘h’ means hexadecimal) or 84h includes one or more status components including basic traffic information such as the average link speed, link travel time, link delay, or congestion type. In the description, specific IDs are described as assignments to structures associated with specific information. The actual value of an assigned ID (e.g., 80h) is exemplary, and different implementations may assign different values for specific associations or circumstances.
The tuner 1 tunes to the frequency of the signals transmitted by the server 100 and the demodulator 2 demodulates the tuned signals in a predetermined manner. The TPEG-CTT decoder 3 decodes the demodulated signals into a TPEG-CTT message sequence as shown in FIG. 2, interprets each TPEG message included in the TPEG-CTT message sequence, and sends necessary information and/or control signals to the navigation engine 5. For purposes of brevity, the following description focuses on basic congestion and travel time status shown in FIGS. 3 b through 3 e and predicted congestion and travel time status shown in FIGS. 4 b through 4 d. Also, for purposes of brevity, tendency has been discussed in terms of trends in traffic congestion. In various implementations, the tendency of other traffic or link characteristics may be included instead of or as well as traffic congestion. For example, various implementations may discuss trends of speed tendency, trends of a tendency of an amount of traffic, or trends of a tendency for a travel time to traverse a particular link.
