| The Galileo Tolls - the ARMAS project |
19/4/2004 |
| Despite the temporary collapse of the satellite-based tolling project in Germany in mid-February, and the adverse publicity surrounding the technology involved, there is an increasing volume of evidence to suggest that wide-area tolling may yet be the protocol of choice in Europe in the foreseeable future.
With the launch, in March this year, of the second phase of the 6th Framework ARMAS (Active Road Management Assisted by Satellite) Project in Portugal, the stage has been set for a determined push by the Europeans for a satellite-based system of road charging. In its sights is the Galileo system that will, eventually, provide a geographical positioning service somewhat similar to that of the American GPS. But Galileo is still some years away and in the meantime the European Space Agency funded ARMAS project will make use of EGNOS (European Geostationary Navigation Overlay Signal) as a staging post on the way to Galileo.
The latest phase of the project is intended to perform live trials that demonstrate and validate a number of functions, including open-road tolling and tolling in the urban environment. I also hopes to allow for the provision of advanced warning message to drivers and an SOS request service. It follows directly on from the earlier stage of the project which concerned itself with the initial definition of the system architecture, a feasibility assessment and proof-of-concept demonstrations.
"Virtual tolling is a major step for implementing a Europe-wide electronic tolling system that allows citizens to travel without physical barriers inside the European Union." says a statement from the European Space Agency, about the ARMAS project.
On-board telematics units, which are confidently expected to become OEM equipment in new vehicles over the next few years, will not only deal with the real-time positioning of vehicles for tolling purposes but will be expected to send and receive information about conditions on the route, according to the ARMAS statement. There are also plans to include the ability to detect and avoid obstacles in the roadway and, if the political will exists, implement ISA (Intelligent Speed Adaptation).
There is, however, still some way to go. Galileo, upon whose successful launch, the future development of ARMAS is predicated, is still in the early stages of its development and the ARMAS partners are still in negotiations on the development of a prototype OBU (on-board unit) by a new partner for the consortium.
The first two of the Galileo satellites were launched in July last year while in February this year, agreement was reached on interoperability with the American GPS system. But that success was only partial as the American government continues to show its reluctance to any agreement to allow the use of a frequency by Galileo that it was hoping to reserve for its own military service due to begin in 2012.
In the meantime, the European Commission is currently in the process of selecting the consortium that will eventually be granted the concession to run the Galileo system from a short-list of three - the Eutelsat Consortium, the iNavSat Consortium and the Vinci Concessions Consortium. Yet there is still no guarantee that member states of the European Union will continue to support the project. It has already had something of a bumpy ride and must be seen to succeed in the harsh climate of the marketplace if it is to have a future.
So far as that goes, revenue from road traffic applications will not be the only source of income for Galileo but it is likely to be significant. This will be particularly true, if the decision is made to implement national distance-based road-user charging for all vehicles at some point in the future. Perhaps the Commission had the future of Galileo in mind when it published its draft Directive on electronic road-user charging at the end of April last year.
Yet even assuming the successful launch of the Galileo system, there will be many who would question the wisdom of imposing a satellite-based system of ETC (electronic tolling collection) on a Europe, already widely served by a highly successful series of DSRC (Dedicated Short Range Communications) equipped systems of tolling. Evidence of this opposition was clear, following the publication of the draft Directive, and is unlikely to abate with the passage of time. France, Austria, Italy, Norway and other member states have all expressed their opposition to the idea of an imposed solution which does not include the use of DSRC.
The problem here, is that the opposition to the imposition of a GNSS/GPRS (Global Navigation Satellite System/General Packet Radio System) is largely self-serving. A great deal of money has been invested by individual companies into DSRC systems and the prospect of losing their investment is not one they relish. Similar reasons could probably be applied to the 10 year failure of CEN (Comité Europeén de Normalisation) to arrive at a European standard for the DSRC protocol.
It is difficult at this stage in the long process towards national or even pan-European, systems of distance-based charging to see the probable outcome in the struggle between the competing technologies. But in a sense, so far as the Portuguese ARMAS project is concerned, the outcome of such distant decisions is irrelevant. The purpose of ARMAS is to demonstrate the art of the possible; to show what can be achieved for road-tolling, traffic management and improved road safety through the use of EGNOS and eventually Galileo. If for no other reason, it is worth serious study.
