DEVELOPMENT, CONSTRUCTION AND PRACTICAL OPERATION OF AN ICE WARNING PROJECT ON STATE HIGHWAY 28

ONTWIKKELING, CONSTRUCTIE EN PRAKTISCH GEBRUIK VAN EEN GLADHEIDSMELDSYSTEEM OP RIJKSWEG 28

The aim of the computerised ice warning system is to predict slipperiness at least one hour in advance. In connection with ice warning the main factors to be measured are: (1) the temperature variation of the road surface; (2) the presence or expected presence of moisture on the road surface; (3) the presence of salt on the road surface. In ten sub-stations of the first ice warning project in the Netherlands the following items are measured: (1) the temperature of the road surface in the wheel tracks of two lanes; (2) the humidity of the road in the wheel tracks of two lanes; (3) air temperature; (4) relative humidity. The data are relayed to a central computer of which the main tasks are: (1) to collect all measured results from the sub-stations every five minutes; (2) to conduct forecasts of measurement values; (3) to issue warnings. Recommendations for improvement are made and financial aspects are discussed. It is pointed out that the full benefit is obtained from an ice warning system only if the operator makes skillful and efficient use of the collected information. /TRRL/
