This technical report presents the results of an analysis of available data relating to unclassified roads. The data items are for whole local government authorities (lgas) and unincorporated areas. Some conclusions drawn from the results are: 1) generally, among states, total road length and road expenditure are related to population; as state population increases so too do road length and expenditure. 2) the categories chosen to group lgas for analysis demonstrate the uneven distribution of population in Australia; urban category lgas contain 59 per cent of the population but only 0.2 per cent of the area whereas the sparse rural category lgas contain 2 per cent of the population in 79 per cent of the area. 3) the major percentage of road length is located in the two least densely populated categories but these only account for a minor proportion of expenditure. 4) the three most densely populated categories account for 75 per cent of the expenditure but only 29 per cent of the road length. 5) unclassified road density decreases with decreasing population density at an accelerating rate, which means that the length of road per person increases with decreasing population density. 6) the standard of unclassified roads provided, as measured by percentage of roads sealed, increases with increasing population density. 7) as one moves from the densely to the more sparsely populated categories expenditure per head of population increases at an accelerating rate. However, the kilometres per head increase at an even greater rate, so that the overall result is that expenditure per kilometre decreases markedly. It is this expenditure per kilometre which determines road quality. (TRRL)
