In "Pay-as-you-go motoring just around the corner," the European Space Agency (ESA) says that "road tolls and car insurance could be made fairer if satellite-assisted distance pricing is implemented."The European Space Agency (ESA) is funding Irish provider of location technology products Mapflow to undertake a feasibility study to look into the possibility of implementing a pan-European road tolling system. The research aims to establish whether satellite technology can be used to calculate the cost of motoring.
A plan exists to complement this activity with a real demonstration of the virtual tolling concept in the greater area of Lisbon. Also under ESA funding, the project is being conducted by the Portuguese company Skysoft in close cooperation with the Portuguese motorway authority. The demonstration is planned for the end of 2004.
Other tests are currently under way in Germany, before a possible generalization in Europe.
The research commissioned by ESA on behalf of the European Union will evaluate the feasibility of a standard tolling approach throughout Europe. The study will look at the effects of such a system on Europe's road infrastructure as well as associated technology impacts.
Potential benefits of a harmonised road tolling system would be fairer implementation of charging on a 'pay for use' basis, lower costs as the need for physical infrastructure is reduced and also reduced congestion.
And as you can see on this picture, there will be no congestion at all. The legend of this picture is: "Satellites could mean 'pay-for-use' road networks" (Credit: ESA).

All these experiments are using the US-operated Global Positioning System (GPS). But in 2010, when the system is fully implemented, it will use Galileo, scheduled to be operational by 2008.
The system will have a constellation of 30 satellites revolving in three circular medium earth orbits, approximately 24 000 km above the earth. This will create a network covering the entire globe, relayed at ground level by stations monitoring the satellites and the quality of their signals.
Once operational, Galileo will provide a highly accurate, guaranteed global positioning service under civilian control. It will be interoperable with other global satellite navigation systems, such as GPS while providing far greater accuracy, down to two metres.

Famous quotes containing the words road, tolling and/or system:
“My father and mother in 1817 were forty-nine days on the road with their emigrant wagons [from Vermont] to Ohio. More than two days for each hour that I spent in the same journey.”
—Rutherford Birchard Hayes (1822–1893)
“... all the cares and anxieties, the trials and disappointments of my whole life, are light, when balanced with my sufferings in childhood and youth from the theological dogmas which I sincerely believed, and the gloom connected with everything associated with the name of religion, the church, the parsonage, the graveyard, and the solemn, tolling bell.”
—Elizabeth Cady Stanton (1815–1902)
“A system of morality which is based on relative emotional values is a mere illusion, a thoroughly vulgar conception which has nothing sound in it and nothing true.”
—Socrates (469–399 B.C.)
