The Arizona Simplified Model for Highway Cost Allocation Studies (Arizona SMHCAS) was developed in 1999 as an alternative to the complicated model for highway cost allocation then available to the Arizona Department of Transportation (ADOT). The Arizona SMHCAS was refined in 2000 and back-tested to determine its suitability as a replacement for the old Arizona highway cost allocation model. Based on this testing, and on continuing problems with use of the old Arizona model, the Arizona SMHCAS was determined to be a suitable replacement. A training program for implementation of the SMHCAS model by ADOT staff was subsequently initiated. The principal means of conducting the ADOT staff training was a complete update of the Arizona SMHCAS for fiscal 2001 to 2005.

The purpose of this report was to update the Arizona highway cost allocation study and to evaluate the alternative of using the new Federal Highway Administration (FHWA) cost allocation model as a replacement. The update revealed that the repeal of Arizona's weight-distance tax has led to a decrease in the payments made by the largest vehicles. As a result, these vehicles are now projected to pay less than their full cost responsibility over the 1999 through 2003 program years. Meanwhile, lighter vehicles will continue to pay more than their full cost responsibility over this same time period. Efforts to use the new FHWA cost allocation model were thwarted by the requirement for data inputs that are not readily available. This data requirement argues against using this new model.

This report pertains to a comprehensive study on infrastructure costs attributable to heavy vehicles. This study has two primary objectives. The first is to review pertinent literature and determine the availability of methods for allocating roadway maintenance costs to different types of vehicle classes. The second objective is to determine the existence and availability of methodologies to estimate the impact of different types of buses on highway infrastructure.
