EXPERIENCES WITH NIMPAC AND IMPLICATIONS OF ALTERNATIVE STANDARDS FOR RURAL HIGHWAYS IN QUEENSLAND

NIMPAC is the road planning model developed to operate on the NAASRA data bank system of road inventory. NIMPAC does this by comparing each road section against assessment standards, identifying deficiencies, and costing measures to correct them. It is possible to vary the assessment standards and the design standards of improvement projects, in successive iterations, to investigate the effect of the changes on assessed road "needs", and to equate assessed needs to the order of vailable funds. Main Roads Department Queensland has undertaken a programme of pilot- testing of NIMPAC by applying it to a 1,400 km section encompassing most of the Bruce Highway. The paper reports the findings to date of this work. The principal findings are confirmation of the rather modest road standards which can be attained on this highway at prevailing levels of road funding. Associated with this work, investigations were also made on the application of NIMPAC to the road under study using a sampling approach. The results of this work would be of interest in designing a large road study to be undertaken by NIMPAC (a). (TRRL)
