Or that there’s not many inland roads that have median separationMy original comment
was in response to this.
The one road I alluded to was clearly the Hume.
Apart from the Barton, and arguably the Federal, and the Hume, every other road has been coastal or on top off the ranges.
The responses seem to indicate that people don't even know that inland Australia exists,
Generally the inland roads have lower numbers of vehicles - which makes it harder to attract funding.
As we (Aust) moves more fully to a Safe Systems approach to roads, which acknowledges that crashes can occur anywhere, we see more road upgrades and changes which will include safe systems elements, particularly median barriers (prevents or reduces the severity of head-ons) wider lanes and wider shoulders (allowed increased recover time from an issue) and shoulder barriers (minimises or reduces run off road, run off road hit object crashes.
Removing at-grade conflict intersections is also a great thing but harder to do (land take, cost, etc, etc).
