Abstract A specific Vcost model was developed for Texas conditions based on a sophisticated fuel model for light duty vehicles, several excellent sources of secondary vehicle cost data, and the ability to measure heavy truck fuel consumption through both experimental and survey work. The basic model was designed to address the relatively narrow range of pavement roughness found on the Texas highway network and is free-flow, and does not accurately measure congestion effects. The team developed a vehicle classification scheme that was suitable for TxDOT planning and revenue forecasting. These resources led to the adoption of eight categories of light-duty vehicles and two heavy truck types. The current Texas fleet composition was determined from 2007 VTR data and was made a default for model use. Each cost item associated with the representative vehicle was calculated for each year of operation up to 20 years. Six main cost categories are included in the Vcost model: depreciation, financing, insurance, other fixed costs, repair and maintenance, and fuel. These costs fall into two categories: fixed and variable costs. The Vcost model can provide operating cost estimates for each specific representative vehicles as well as fleets of vehicles. The model allows the user to change key parameters so that the cost calculation is specific to any particular situation, and can be updated as the economic or technological landscape changes. The model was designed to provide the user with a program that looked, felt, and operated in a similar fashion to most Windows programs and would be intuitive for the typical TxDOT user. 17.

Project Engineer: Dr. Ronald Matthews Professional Engineer License State and Number: 52561 v Acknowledgments The team wishes to acknowledge and thank the consistent leadership and support provided by the Project Director Don Lewis (GSD) and Dr. Duncan Stewart (RTI), ably supported by the project advisors Janie Temple (TPP), Jackie Ploch (ENV) , Jo Woten (GSD), Paul Campbell (FIN), and Peggy Thurin P.E. (TPP). The experimental work relied on the assistance of many GSD staff who are thanked as a group. Finally, the rolling resistance experiments for heavy trucks could not have been completed without the commitment of both Bruce Merrill, P.E. (AUS), who reserved the highway for the test and the trucks, and the fleet manager and drivers from HEB who worked over a test weekend. The HEB effort was led by Kenneth Allen, V.P Supply Chain and Logistics and Mike Moynahan, Fleet Manager, and was crucial in determining future heavy truck technologies, the impact of extra-wide tires, and the rolling resistance tests. Technical assistance was also provided by David Higbie, Ram Chandrasekaran, and Mohamed Gouda (AVL); Stephen Allen and Steve Stillman (Antx); Herman Masse, Roger Van Elslander and Mike Bartkowiak (Dearborn Group Technology); Vitaliy Maksimov and Mike McBeath (ScanTool.net); Lee Butler (Greatwide); Lance Shillingburg and Les Findeisen (TMTA); Dennis Beale (FedEx Freight); and Brad Bryant (Wal-Mart); and Bob Davie (Vanguard Trucks). Finally, David Schwarz (Consultant) and Emre Meric (Microsoft) assisted on software issues. Our thanks are extended to all these individuals and companies that helped frame the study and address key issues. vi Table of Contents Chapter 1.
