Guide to Road Tunnels Part 2 Update: Rationalising Network Signage for Over-height Vehicles

December 2, 2021

A recently completed project has recommended changes to the Austroads Guide to Road Tunnels Part 2: Planning, Design and Commissioning to provide guidance on rationalising road signs on the approaches to tunnels, to divert over-height and dangerous goods vehicles that approach tunnel entrances.

When these vehicles attempt to pass through tunnels that have not been designed to cater for them, this can cause significant damage to the infrastructure, massive traffic congestion and, in some unfortunate circumstances, injury or loss of life of the motorists. As such, it is highly advantageous to divert these vehicles away from tunnels wherever possible to reduce these negative impacts.

This webinar, presented by Bob Allen, Marcus van der Velden, Lindsay Edmonds and Charmaine Joe, covers the following:

  • Project methodology and key findings of the review
  • Current signage practices review and gap analysis
  • Proposed signage scheme
  • Human factors considerations.
