Updated Roadside Design Guidance – Crash Risk Evaluation Procedure Background

Watch Now:

Minimising the risk of roadside crashes is important in reducing the number of fatalities and serious injuries on our roads. The recently updated Part 6 of the Austroads Guide to Road Design includes a new method to determine the risk associated with roadside crashes and to identify where risk mitigation treatments are required on urban and rural road networks. The approach establishes a Network Roadside Risk Threshold (NRRIT) which consistently directs the locations for treatments within projects.

This webinar, presented by Peter Ellis and Rod Troutbeck on 6 October 2020, describes the procedure’s background in detail explaining the concepts and research behind it.

Updated Roadside Design Guidance – Crash Risk Evaluation

Watch Now:

Minimising the risk of roadside crashes is important in reducing the number of fatalities and serious injuries on our roads. The recently updated Part 6 of the Austroads Guide to Road Design includes a new method to determine the risk associated with roadside crashes and to identify where risk mitigation treatments are required on urban and rural road networks. The approach establishes a Network Roadside Risk Threshold (NRRIT) which consistently directs the locations for treatments within projects.

This webinar is focused on user guidance, including the practical application of the new method. The webinar describes the new procedure for evaluating a rural road network, how policies will influence decisions and how the NRRIT can consistently delineate road sections where treatments are required.

The webinar also provides the basis of the procedure by using a simpler example so that participants can appreciate its broader application. The example demonstrates how risk graphs, based on contemporary knowledge, can be used to expedite the assessment procedure.

An Introduction to the Austroads Design Vehicles and Turning Path Templates

Watch Now:

This webinar provides an introduction to the Austroads Design Vehicles and Turning Path Templates. The vehicle turning path templates are primarily used in the design of intersections. The show plots of vehicle wheelpaths and the path traced by other relevant points on the vehicle or load at different speeds. The webinar was presented by Peter Eady in 2013.
