Over-height vehicle incidents continue to present safety, operational and asset protection risks in tunnel environments across Australia and New Zealand. Even when a vehicle is stopped before entering a tunnel, its safe removal can cause significant network disruption.

This webinar will present findings from the Austroads research report Managing Over-height Vehicles in Tunnels. It will examine how vehicles already on the road network and at risk of entering managed tunnels are addressed across the prevention, mitigation, response and recovery stages. The research draws on literature, stakeholder engagement, a review of selected Australian and New Zealand tunnels, and Australian, New Zealand and international case studies.

The session will highlight opportunities to improve early detection, driver communication, time and distance for safe diversion, system integration and coordinated incident response. It will also discuss improving incident data, assessing improvements to legacy tunnels and strengthening Austroads guidance.

The webinar is suited to road authorities, tunnel operators, transport practitioners, ITS specialists, freight representatives and incident response professionals.

This webinar is presented by Chris Adams, Shifani Sood and Tom Betts.
