The effectiveness of winter maintenance with regard to road safety and the economic repercussions for traffic movements have been under study for approximately ten years. Results are already available for single lane rural roads, with initial findings in for motorways and urban and suburban roads. The methodology behind these records is based on a variety of information available from winter maintenance services (operational reports), the police (accident reports), highway authorities (traffic and road data) and meteorological offices (monthly weather reports) which can be readily collected and evaluated by computer. It is supplemented by traffic counts and speed measurements. On this basis, after collecting the data, an attempt is made to work out a half-hourly accident cost rate on roads in winter and to calculate the usefulness of winter maintenance in the first hour after starting operation and to ascertain the effectiveness of winter maintenance as a whole for highway networks or specific stretches of road.
