Effectiveness of Winter Maintenance Strategies

MaineDOT snow and ice control policies and processes have changed dramatically over the past few years. Salt priority, anti-icing and ground speed control are only some of the new strategies now being used. There is a need to evaluate the effectiveness of these strategies on a year to year basis. This will serve as a means to justify the changes to ourselves and to the public. The comparison of salt usage or hours of snow plowing, itself, will not give a complete picture of effectiveness. A measure of the winter severity from year to year also is important to develop. The "winter severity index" should be representative of Maine's regions and use data that is available from previous years. The tasks include developing winter severity indices, comparing strategies, developing recommendations and final report. The study will take 18 months to complete.
