The Audit dataset provides a broad range of data about corridors, and there are many ways of analysing this data. Given the focus of the Audit on economic indicators, the analysis in Table 13 and Table 14 focuses on delay cost. This applies a dollar cost to time delays, based on lost productivity, and taking account of the different costs applicable to different vehicle types.
Some users of the Audit dataset may prefer to use more traditional indicators of congestion such as traffic V/C. This measure is included in Table 13 and Table 14, as is the DEC measure, which gives insight into the underlying value of activity on the corridor, and the proportion of DEC attributable to delay cost.
These measures are expressed per lane kilometre of road. This normalises the results to facilitate comparison across a wide range of different corridor types - some very long, some consisting of multiple roads (and roads with single or multiple lanes), and some relatively short single roads. This provides, for the first time in Australia, a tool which allows comparison of urban transport corridors across different cities, by key attributes such as delay cost and value-add.
Table 13 shows corridors ranked by delay cost per lane kilometre in 2011, with the equivalent projections for 2031 in Table 12. Taken together, these tables give an indication of which corridors warrant further study, and where interventions are likely to have the greatest economic return.
