The amount of traffic information included in traffic message frames broadcast to users, for example via a Transport Protocol Experts Group (TPEG) frame, can be reduced by using configurable bounding areas for different road classes (types). A broadcast area associated with a primary bounding area can be divided into sub-bounding areas. Rather than broadcasting information for all roads of all classes in the broadcast area, each road class is associated with a particular bounding area. Traffic information pertaining to roads located within a bounding area that have road classifications matching bounding area road classifications is included in a TPEG frame. For example, if a class 4 road is located within a sub-bounding area associated only with road classifications 0-3, information about that particular road can be excluded from the broadcast traffic information, even if it is located within the primary bounding area.
