The reduction of snow removal expenditures is a pressing need for governments in Japan. Reducing snow removal expenditures at the national government level requires the following: 1) analysis of the cost structure, 2) development of a method for comparing costs among regions, and 3) development of cost reduction standards. We studied methods for objectively determining the cost effectiveness of snow removal, toward inter-regional comparison that has been regarded as difficult. To this end, we developed a model uses a linear regression line of "unit cost of snow removal" (UCSR) that is based on the relationship between snow removal costs and cumulative snowfall. This study presents how the model has been developed and discusses its applicability by using actual snow removal records. We also examine applicability of the model when the data from which the model is derived include those for an extremely snowy year and an unusually less snowy year.
