Dynamic speed adaptation in adverse conditions

Varhelyi, Andras LU (2002) In IATSS Research p.52-59
Abstract
This paper proposes a system for dynamic speed adaptation in adverse conditions, such as wet/slippery roads, decreased visibility, darkness and sharp curves. Accident risks increase drastically in such conditions, especially since drivers often do not adapt speeds to lower friction or impaired visibility. Thus, the discussion is centred around a method for calculating the appropriate highest speeds and a system to influence driver’s speed-choice in these conditions via an in-vehicle device. The safety effect of the proposed system is estimated to result in a 19% - 42% reduction of injury accidents in Sweden. The paper concludes by making suggestions for further research into alternative technological solutions, effects on driver behaviour... (More)

The safety effect of the proposed system is estimated to result in a 19% - 42% reduction of injury accidents in Sweden. The paper concludes by making suggestions for further research into alternative technological solutions, effects on driver behaviour and workload and implementation of the system for other reasons than weather and road-dependent adverse conditions.
