A Benefit/Cost Analysis of Intelligent Transportation System Applications for Winter Maintenance
This paper explores the feasibility of incorporating an intelligent transportation system (ITS) method to assist maintenance operations at a high accident location on Interstate 90 in Washington State. The section of I-90 is located near Vantage, Washington just east of the Columbia River and is under the jurisdiction of the Washington State DOT North Central Region. A portion of this corridor is highly prone to ice and snow related accidents. Only that portion is addressed in this paper. It is proposed to address ice and snow related accidents by preventing the formation of ice on the roadway surface. The process explored by this paper is with anti-icing chemicals applied to the roadway surface by an automatic anti-icing system. This paper identifies the system costs, cost savings due to accident prevention and calculates a benefit-cost ratio.
