SLIDE 3
Traffic accidents in Sweden 1995-1999:
- 37828 at snowy or icy road
surface conditions, of these did
- 15589 occur during black
ice conditions, and in addition did
- 572 accidents related to
aquaplaning occur
SLIDE 4
General properties
Uses infrared spectroscopy IR emission IR reception B IR reception A
SLIDE 5
General properties
Principles of spectroscopy
- Ice transparent to visible light
- Ice is reflective (metal like) in the
MIR range
- Ice is distinctly ”coloured” in the
NIR range
