In response to congressional action and an executive order AASHTO formed a task force to investigate metrication. In its report, the task force recommended development of the AASHTO "Guide to Metric Conversion". The guide, a document prepared to help steer the American highway industry through metric conversion, was prepared by the University of Alabama, through a contract with NCHRP. Chapters in the guide introduce the reasons for conversion, give examples of conversions by other nations, outline the steps in forming an agency conversion plan, give hints and suggestions, and provide checklists of suggested activities. Appendices provide tables of metric conversion factors, critical geometric design criteria expressed in metric units, and case studies that list conversion activities and estimated costs for two branches of highway agencies. Example materials taken from the guide are discussed to illustrate the content of the document, which was published by AASHTO in 1993.
