The NAASRA Roads Study (NRS) is being undertaken on three basic classes of roads, urban arterials, rural arterials and local roads. These classes are each defined in terms of the NAASRA functional classes of roads which comprise them. This report provides a brief history of the development of the NAASRA functional classification of roads, the definition of each classification and an explanation of the definitions. All this will demonstrate that it is not possible to derive a unique NAASRA functional classification for a state's road system, which explains why changes have occurred in the various states from time to time. The dates when major reviews of the NAASRA functional class system were undertaken in each state are given and the differences between the classifications used for the NRS and those preceding them are summarized. An analysis of the classification for NRS purposes is also made in the report. For rural arterial roads this covers the characteristics of key towns and important centres, conformity with definitions and a description of traffic, town spacing and population characteristics along routes of each functional classification. For urban arterial roads the analysis covers road density, broad demand/supply parameters, traffic and network completeness. Finally, the report describes the relationship in each state between the present NAASRA functional classification, state legal classification and commonwealth legal classification systems. (TRRL)
