The RMS has created a Guide To Traffic And Transport For Special Events. According to The Guide, the level of detail required for a Traffic Management Plan varies depending on the Class of Event:
Class 1:
Is an event that impacts major traffic and transport systems, and disrupts the non-event community over a wide area. For example an event that reduces the capacity of the main highway through a country town or a bicycle race that involves the Sydney Harbour Bridge.
For a Class 1 event it is recommended all relevant stakeholders have been informed, and approvals sought at least 4 months prior to your event.
Class 2:
Impacts local traffic and transport systems but does not impact major traffic and transport systems, and disrupts the non-event community in the area around the event, but not over a wide area. For example an event that blocks off the main street of a town or shopping centre but does not impact a principal transport route or a highway.
For a Class 2 event it is recommended all relevant stakeholders have been informed, and approvals sought at least 3 months prior to your event.
Class 3:
Does not impact local or major traffic and transport systems, and disrupts the non-event community in the immediate area only. For example an on-street neighbourhood Christmas party.
For a Class 3 event it is recommended all relevant stakeholders have been informed, and approvals sought at least 2 months prior to your event.
Class 4:
Is intended for small on street events and requires Police consent only. For example a small ANZAC Day march in a country town.
For a Class 4 event it is recommended all relevant stakeholders have been informed, and approvals sought at least 1 month prior to your event.
Special Events in Streets and Laneways:
Intended for events in a road, street or laneway (e.g. a street fair) where temporary closure would be required.
