Statewide On-road Capital Cost Model (10/24/2008):   The Statewide On-Road Capital Cost Model is a program that has been automated to evaluate multiple individual company fleets in a single program. The model is a Visual Basic module that runs within an Access database and utilizes Access queries. The modeling approach and assumptions are described in detail in Chapter XIII and Appendix J of the October 2008 Technical Support Document: Proposed Regulation for In-Use On-Road Diesel Vehicles. The zipped file is approximately 600 kilobytes, the uncompressed file is approximately 5.5 MB but will substantially increase in size as it is used. The output of this model only includes equipment capital costs. [NOTE: This model is computationally intensive and may exceed the limits of a computer's operating system depending on how many vehicles are included in the model run.] Statewide On-road Capital Cost Model October-2008
