TPEG (Transport Protocol Experts Group) is a protocol specification for the exchange of RTTI (Real Time Traffic Information) to provide road users with comprehensive, up-to-date traffic and traveller information across multiple transport modes. TPEG describes real-world events and situational data with their spatio-temporal scope, i.e. the geographical location and time or time period they are associated with. This document focuses on the new location referencing method named TPEG2-ULR (Universal Location Referencing), and especially introduces a map matching algorithm designed for linear locations. A new approach has been pursued which substantially differs from existing techniques. The new method communicates linear locations in the form of formalized direction instructions, similar to t he directions communicated between humans (turn right after 500m), together with a pair of source point and destination point co-ordinates.
