Title:
Development of RWIS: A New Approach using Accident Data
Abstract:
This study focused upon winter road accidents and the relationship to weather and slipperiness. Data from the Swedish RWIS is used to classify the type of slipperiness and the severity of the situation in relation to the number of road accidents that take place during each specific situation. The result shows a very clear picture that the number of accidents increases with increasing severity of the situation. Most accidents occur during situation with rain and a surface temperature around 0 degrees C and during situation with snow.
