| Europe-wide speed warning system proposed.

An initiative, supported by DG TREN, is looking a ways in which drivers throughout the EU can automatically be warned if they exceed the speed limit.
The twelve month Speed Alert study, which has representatives from five European countries, four of which are currently involved in ISA trials, has as its main objective the 'harmonisation of the speed-alert concept definition', based on an in-vehicle unit.
"There is a clear distinction between the aims of this project and those of ISA," said Vincent Blervaque, the Speed Alert Project Manager. "This is based on informative systems and there is no active interference (with the engine management system)."
Project members, who include representatives of DG TREN, DG INFO, ACER, vehicle manufacturers, system suppliers and the FIA (Fédération Internationale Automobile) were informed at their 4th October workshop meeting in Brussels that the underlying principles behind the project's objective were safety and mobility on the European roads network.
Three in-vehicle systems are under active consideration by the group. They are:
ˇ a stand-alone in-vehicle system as an extension of the inboard navigation system. The disadvantage of this system is that it carries the risk of becoming quickly out of date and therefore inaccurate. It would also be unable to deal with variable and temporary speed restrictions.
ˇ a simple OBU receiving data from network of roadside beacons. While accurate and able to deal with variations in the speed limit, the system is seen as being costly.
ˇ an autonomous OBU, a co-operative concept retaining static information on digital, in-vehicle map but capable of receiving infrastructure information updates
