DETERMINATION OF ROAD UPGRADING PRIORITIES IN URBAN AND REMOTE AREAS

The availability of funds for road works programmes is of major concern to local authorities and increased emphasis is therefore required to maximise the benefits from available finance. Two methods of determining road upgrading priorities applicable to urban and remote areas respectively are described. The first method, in relation to urban areas, involves the use of traditional transport planning procedures that can be applied quickly and cheaply to determine the need for road upgradings on a systematic basis. Because of their low cost, these procedures lend themselves to repeated application, which, in conjunction with a program of network monitoring allows a continued updating and revision of identified road needs. The second method, in relation to remote areas, was developed for a study of road development requirements in central Australia. Conventional techniques to appraise road upgrading projects are only applicable to roads with substantial traffic volumes, say in excess of 50 vpd. In outback areas, for instance, much lower volumes are normal, and benefits are related less to road use than to the quality and reliability of access which a given road affords those who are dependent on it. A new technique was therefore developed which in essence, provides an objective and consistent basis for what were formerly subjective judgements about the relative importance of a variety of road functions. The result is a ranking of roads, without any attempt at an absolute measure of feasibility. Examples of the use and advantages of these methods are described. (Author/TRRL)
