Traffic Management

Austroads has developed an extended vehicle classification scheme (EVCS) to enable improved understanding and monitoring of the evolving vehicle mix on Australian and New Zealand roads in traffic and transport surveys. This builds upon the existing 1994 vehicle classification scheme.

The EVCS provides greater granularity for each of the existing 12 classes of vehicles and adds a new class for active transport to address the need to count a variety of active transport users such as pedestrians, skateboards and e-scooters.

The EVCS will allow transport agencies to better manage transport demand within and between modes, survey active transport and understand how demands integrate with other modes.

The scheme will help identify changes in transport operational performance and optimise plans for effective access management and asset maintenance.

This webinar, presented by Drew Gaynor and David Johnston, is the first session in a three-webinar series, and it focuses on the changes to heavy vehicles. The second webinar will cover light vehicles and the third session will provide information on measuring active transport.

This webinar discusses:

• level 3 classes 3 to 12
• the greater granularity in level 4 subclasses
• better description of axle groupings
• the creation of a new class 19 for heavy vehicles that do not fit readily into the prescribed classifications
• backward compatibility with existing heavy vehicles counting
• further validation of some sections.
