There are 2,670 kilometres of risk-rated national highway in the Northern Territory, which is 13 per cent of the total National Land Transport Network. During the period from 2010 to 2014, there were 548 casualty crashes on these roads, accounting for four per cent of the national total. These casualty crashes included 61 deaths, which equates to just under seven per cent of total fatalities across the network.
The following table lists the national highways in the Northern Territory, with aggregated information provided.
The Stuart Highway constitutes 66 per cent of the total length
of the assessed network in the Northern Territory. It has
disproportionately high casualty crash and fatality figures at 84
and 82 per cent respectively.
The following table lists the sections of national highway in the Northern Territory with the highest combined risk. The combined risk scores for the top six highway sections in the Northern Territory are statistically very similar, such that it is difficult to distinguish which of these sections should be prioritised for safety improvement on the basis of combined risk scoring alone.
The four of the 14 sections of national highway with the best risk scores in the Northern Territory are presented in the table below, ranked from lowest to highest risk. This shows that even the best highways in this jurisdiction have significant room for improvement.
