Geographic information forms a major part of the information that is communicated in applications of traffic (and traveller) telematics. The geographic information component is needed to answer questions such as:
"Where am I?"
"Where are you?"
"Where is the accident?"
The form of the answer depends on the spatial reference system used. Generally speaking, answers to "Where?" may range from positions expressed exclusively in terms of scientific co-ordinates expressed in terms of objects of direct human experience (called locations in traffic telematics terminology). A location may be a road crossing or section, relation between road sections or a point of interest.
Consequently, digital map databases play a vital role in most traffic telematics applications. In the chain of creating, providing and using traffic and related information, a traffic message is created in the sending system and transmitted and used in the receiving system. The traffic information in the message is related to a location and this location is referenced by a code, called a location reference. A problem is caused by the fact that the sending and the receiving system may - and often will - use map databases of different origin, specification and completeness.
A new generic method for location referencing was successfully implemented, tested and validated in a laboratory type map database environment (TR4011-EVIDENCE). The method is designed for traffic telematics systems that use a digital map on both ends of the communication chain. A location code is created when needed from the map database in the sending system, embedded in a message, sent on wireless data carriers, and interpreted by the receiver using the information in its map database. Pre-coding of locations, maintenance, and dissemination of location tables are no longer necessary.
The AGORA project's key objectives are to:
AGORA is an 18-month project (October 2000 – March 2002) and includes the set of actors necessary to build trials/tests addressing the entire telematics chain: major map providers, content/service providers and users/terminal manufacturers. To realise the AGORA's overall objectives, the following operational objectives have been defined which give a summary of the work to be carried out in AGORA, which include to:
AGORA's technical target: location presented in the terminal is identical to the originally identified location.
AGORA's business target: adapt this location referencing method for widespread use in transport telematics applications and foster interoperability.
Due to these factors, AGORA must build a trial implementing the full telematics service chain with respect to location referencing. The Hannover region has been chosen for the quality of the available information used at the EXPO 2000, and achieved results could be extrapolated all over Europe.
