High potentials for convincing ideas

   High potentials
for convincing ideas
“Action is for sure better than a lot of talking. We have realised that ambitious actions actually meet political support and citizens’ acceptance”, says Maria Alfayate from the DG for Energy and Transport, talking about experiences and achievements within Trendsetter and Civitas. But the implementation of innovative measures isn’t always done that easily.
“We are confronted with quite a large number of mental, legal and organisational barriers which have to be smoothed out before anything can be changed”. One of the most important factors to get things moved are public-private partnerships. They are to be developed at any rate in order to get work done efficiently and fast.

Speed adaption

ISA (Intelligent Speed Adaptation) provides the driver continuously with information about local speed limits, warns the driver when speeding, by sound or light signals or react automatically to make speeding impossible. Results of actual experiments with ISA show that the system works quite fi ne.
- The main problem is the acceptance of the system by the drivers, explains Karin Bäfver who has conducted an ISA-study in The Hague.
- Many people feel continuously watched by ISA and associate unconsciously ‘Big Brother is watching you’. The information about local speed limits can be obtained in different ways: By manual adjustment of a maximum level driver; by a signal to the vehicle, from a beacon along the road driven on; or by a GPS-System.
Swedish research indicates that the acceptance of this system is greater after experiencing the ISA’s obligatory speed reduction.When car drivers have the choice between an ISA system and speed control humps, they choose for ISA. And the system has also some influence on driver’s behaviour. Some Sweedish studies show a reduction of the average speed, a more constant speed, an increase in travel time and an
increased alertness towards other road users.
The Real Estate and Traffic Adminstration in Stockholm has recently equipped twenty of the City’s vehicles with ISA and produces a road map with digital speed limits. The ambition is to equip all the city´s 1,000 cars with the technique up to year 2010.

Traffic-responsive Urban Control

Traffic-responsive Urban Control (TUC) employs advanced automatic control methodologies and has one enormous advantage – it is easy to implement and it is simple and flexible.
Until today three cities namely Chania (Greece) Southampton
and Munich have tested and evaluated the new control strategy.
“After the successful implementation of TUC we tend to undertake further iprovements in order to make the system more efficient“, says Elias Kosmatopoulos from the Technical University
of Crete.
