15.3.2.2 User Vehicle Operating Costs
User vehicle operating cost is also a commonly used MOE for assessing both traditional capacity-related transportation improvements and TSMO projects. User vehicle operating costs can be split up by fuel use or nonfuel use costs. Nonfuel costs include maintenance, insurance, and vehicle depreciation costs. The fuel use MOE is typically estimated by applying a rate of average fuel use to the net change in vehicle miles of travel (VMT).
