Road location and traffic data

This dataset contains the Department of Transport and Main Roads road location details (both spatial and through distance) as well as associated traffic data.

It allows users to locate themselves with respect to road section number and through distance using the spatial coordinates on the state-controlled road network.

Through distance – the distance in kilometres measured from the gazetted start point of the road section.

southbound off ramp chainages are increasing south instead of north

Hi Peter,

Thank you for your enquiry. We have checked the data you mentioned and found it to be correct. We have assumed your query is about the southbound off ramp to Uhlman Road (from 18.48 to 19.05km) as that is the only one in that area fitting your description.

Our ramp chainage convention is that regardless of driving direction, a ramp starts where it meets the through carriageway, IE at 18.48km at the exit point to the ramp and ends at a greater chainage, IE 19.05km at the intersection with Uhlman Road – even though it’s south of the start point.

Is there any chance this marker could be added to this dataset?
