TR_ROAD_REGISTER forms the basis of the road register for Victoria.
Road segements (TR_ROAD) are grouped by road name, road type, road suffix and locality using the TR_ROAD_LOCALITY_SECTION and TR_ROAD_LOCALITY tables to create a single line feature for each unique combination of values.
This dataset compliments TR_ROAD. Where a road segement has multiple names, TR_ROAD_REGISTER will have multiple overlappling road lines while TR_ROAD will have one road with multiple names.
TR_ROAD_REGISTER facilitates road searching and efficent road name lablelling.
In addition the dataset has an atttribute MIN_CLASS_CODE which is the the minimum CLASS_CODE for all TR_ROAD road lines that have the unique cominbination of identifer vaules. For example, if the road segments associated with the unique road identifer have CLASS_CODES of 0 (Freeway), 1 (Highway) and 2 (Arterial), the MIN_CLASS_CODE of that road will be 0 (Freeway). This value faciliates feature filtering at different scales and symbolisation.
