Road infrastructure investments are currently planned and prioritised under what could be considered a ‘top-down’ process. Road agencies are typically funded through budgetary processes whereby road funding needs are mostly weighed against other budget priorities. However, when a road is a lifeline route – where there are limited transportation alternatives –the external impacts and costs imposed on both users and non-users from this road becoming inaccessible can be very significant.

These impacts can be difficult to both measure and value and, because of this, lifeline routes may have been historically underfunded. This is pertinent with climate change meaning that road managers are increasingly encountering problems managing natural hazard events on lifeline routes.

In light of this, Austroads has updated their Lifeline Risk Indicator Tool and migrated it to the Austroads website as an online-enabled tool. This tool has two purposes. First is to identify lifeline freight routes and allow road managers to establish a lifeline route network. Second is to rank investments in lifeline routes in terms of economic and social impacts.

This webinar, presented by Ben Mason, Dr Stacy Rendall and Valentin Perez, stepped through the process undertaken to update the tool and a practical run through of how the web-based Lifeline Risk Indicator Tool can be used.
