Real time traffic and traveller information (RTTI) services use various methods to describe the affected location of an event. As the successor to TPEG-LOC, the Universal Location Referencing (ULR) method of the TPEG standard family is a new, open and royalty-free method for dynamic location referencing that provides an efficient and compact coding of a geographical location both for purposes of human-readable presentation and for automated processing, e.g. in GPS navigation systems. TPEG-ULR introduces an innovative approach for dynamic location referencing based on Markov chains, but also supports mapless-client applications. Development of TPEG-ULR was motivated both by technical considerations and commercial issues with other location referencing methods. TPEG-ULR is especially suitable for public digital broadcasting applications such as DAB(+).
