Abstract: A boundary specifying a bounded geographic area for which travel information is to be reported is generated. Flow section information associated with flow sections located within the boundary is obtained. The flow sections represent portions of one or more roadways assigned relevant functional road classes (FRCs). The flow section information includes information about traffic flow associated with the flow sections. FRC current traffic messages, which include non-predictive traffic information associated with roadway portions that are in the bounded geographic area and are assigned relevant FRCs, are combined with the flow section information to generate a first data group. The first data group is streamed to a first traffic message service.

Abstract: Travel-related-information messages (TRIMS) are received from one or more information sources, and information included in the messages is separated into a first (e.g. TPEG™) or second (e.g. TPEG+) group. A broadcast area to which the information included in the TRIMs is to be broadcast is determined. A further determination indicates that a subset of information assigned to the first group is to be reassigned to the second group. The subset of information is reassigned from the first group to the second group based on parameters associated with the broadcast area. The information included in the first group and the second group is delivered to one or more processing modules that generate a first TRIM reporting message using information included in the first group and a second TRIM reporting message using information included in the second group.

Abstract: A system includes a processor configured to determine that transmission data indicates that first data was transmitted via a digital radio channel and that reception data indicates that second data was received via the digital radio channel. The first data is transmitted concurrently with transmission of an analog signal. The processor is configured to detect an error in transmission of the first data based on a comparison of adjacent portions of the first data to non-adjacent portions of the second data. The processor is configured to, in response to detecting the error, initiate display of a default image concurrently with output of an audio signal that is based on the analog signal and to initiate retransmission of the first data to cause second particular data to be output subsequent to the output of the default image. The second particular data corresponds to the retransmitted first data.

Abstract: Travel-related-information messages (TRIMS) are received from one or more information sources, and information included in the messages is placed into a first (e.g. TPEG™) or second (e.g. TPEG+) group. A determination is made that a first TRIM reporting message including information from the first group will exceed a permissible size, so excess information is removed from the first group and added to the second group, thereby decreasing the size of the first TRIM reporting message to the permissible message size or less. Some or all of the excess information removed from the first group is added to the second group. First and second TRIM reporting messages are generated from information included in the first and second groups. The first and second TRIM reporting messages are transmitted to end-user devices using different service ports.

Abstract: A method includes determining, at a device, that transmission data indicates that first data was transmitted via a digital radio channel. The method also includes determining, at the device, that reception data indicates that second data was received via the digital radio channel. The first data has a first size that is less than a second size of the second data. The method also includes determining, at the device, whether an error occurred in transmission of the first data based on determining whether each of a plurality of portions of the first data is included at least once in the second data. Other aspects are also disclosed.
