Abstract
A computer implemented method of compressing a plurality of TPEG format traffic messages is provided. The method forms a template containing the data values of fields of a message management container, an event container and a location container and forms a global data set representing a base time of the traffic messages and data indicating the geographic region. The method creates compressed TPEG traffic messages comprising a template identification indicating the template and data values of the fields of the message management container, the event container and the location container not included in the template or global data set.
