Researchers at the 933 Fraunhofer Institute for Communication Systems ESK in Munich, Germany, have developed a car-to-x communication (C2X) system that makes structured communication possible between an electronic unit in the vehicle and the outside world.

According to Josef Jiru, the project manager, “This system is premised upon on a WLAN specifically developed for vehicles in combination with GPS. The vehicle’s position and sensor data on speed, acceleration or sliding can be reported to wireless communication roadside units (RSUs).”

In exchange, the RSUs give vehicles three types of information – standardized messages that every car transmits to other cars and the RSUs up to ten times a second; event-based information such as notifications of accidents; and application information, for instance on traffic-light sequences that vehicles can exchange with one another, along with traffic information generally.

    The logic supporting a cross-border enforcement Directive for the European Union (EU) is both detailed and compelling. The White Paper on European transport policy published in 2001 included the ambitious objective of reducing by 50 per cent by 2010 the number of people killed on the roads of the EU. But since 2005 the reduction in the number of road deaths has been slowing down: overall, the period from 2001 until 2009 saw the number of fatalities decrease by 36 per cent.

    Are pre-launch trials of charging systems the way to improve public acceptance? Or is the real key a more robust political attitude? Here, leading system suppliers discuss the issue. The use of distance-based Road User Charging (RUC) is now well established, at least for heavy goods vehicles on strategic roads. However demand management for all vehicles, whether a distance-based charge or some form of cordon scheme, has yet to make significant progress. This is in spite of the logic and equity of RUC being
