The dynamic location referencing method AGORA-C has been successfully implemented and tested in Japan by Panasonic. The verification exercise showed that the method achieved 95.6% accuracy on identifying the section of road, and 99.1% accuracy on identifying the length of road.

Location referencing is the task of ensuring compatible referencing of locations when information is exchanged between different applications or systems with different geographic databases. The ISO 17572 series, which was published in December 2008, defines two methods for location referencing.

The first method (ISO 17572-2) “Pre-coded Location Referencing”, assumes common pre-coded tables, such as the European Traffic Message Channel (TMC) or the equivalent Japanese Vehicle Information and Communication System (VICS).

The second method (ISO 17572-3), “Dynamic Location References” (DLR), works by encoding locations on the road network, such as intersections and road sections. It anticipates differences between map versions at the time of decoding and snaps to the corresponding map location when placed on a target map. DLR has evolved from the European “AGORA-C” proposal, developed in the European Commission’s Fifth Framework AGORA Project (implementAtion of Global lOcation Referencing Approach). AGORA-C supports location referencing without needing pre-encoded locations or needing the source and destination of a message to use the same reference map.

Panasonic have published a short document detailing their verification trial, which can be downloaded from www.tisa.org/. Further information can be found in the ITS Radar International November 2008 Newsletter.
