The Per-Mile Costs of Operating Automobiles and Trucks Status: CompleteReport Date: 10/26/2003 Summary: This report provides a spreadsheet model for calculating the costs of operating cars and trucks. This cost will be used in the planning of highway projects. One challenge faced by the researchers is the fact that highway projects alter the vehicle operations costs. The researchers used innovative methods to determine the travel cost estimates based on usage, while excluding the fixed costs of vehicle ownership. The research also offers methods to adjust the costs for different driving conditions, like smooth or rough roads. The report also suggests methods to determine what the cost of operating a personal vehicle or truck will be in the future.
