16. Abstract This report was prepared by a team of graduate students in the Management Information Systems Department at the University of Arizona. The purpose of this project was to: Determine if the Highway Economic Requirements System (HERS) analysis program is suitable for use by the Arizona Department of Transportation; If not, determine if it could be made suitable with some manageable modifications; and If no manageable modifications seem reasonably workable, recommend a path the Arizona Department of Transportation should take for achieving its asset management objectives.
The team concluded that: The Highway Economic Requirements System, even when modified for the Arizona Department of Transportation environment, will not meet Transportation Infrastructure Asset Management requirements and is not a product on which to base an On-Line Analytical Processing (OLAP) System from either a user or an organizational viewpoint. A model framework for an analysis that can be a start for achieving Arizona Department of Transportation asset evaluation needs is the Transportation Economic and Land Use System (TELUS). 17.

EXECUTIVE SUMMARY
The Arizona Department of Transportation (ADOT) is in the process of implementing an Asset Information Data Warehouse. The Arizona Department of Transportation invests hundreds of millions of dollars annually on the construction, enhancement, rehabilitation, and maintenance of multi-billion dollar assets for public use. The Arizona Department of Transportation wishes to effectively leverage information, in addition to engineering data, and apply it towards making better investment decisions. The Asset Information Data Warehouse (AIDW) will be used as a decision support system for Arizona Department of Transportation projects. Ways in which the Asset Information Data Warehouse information will be used are needed to effectively prioritize, propose, and provide performance feedback for Arizona Department of Transportation programs.
