Title:
The Effects of Weather and Road Condition Warnings on Driver Behaviour
Abstract:
Road safety has steadily improved in Finland during the last years except for accidents in wintry road conditions. The primary measure used to decrease these accidents is to improve road surface conditions with the help of road maintenance actions. Time is critical as the accident risk in the hour preceding maintenance actions is estimated to be 12 times as high as it was 12 hours earlier. Hence, the Finnish National Road Administration (FinnRA) wished to improve safety in the period from first indication at the Road Weather Monitoring Centre to the start of maintenance actions by warning road users about possible slipperiness. A pilot warning system utiliizing dynamic message signs was tested in FinnRA's Turku district.
