53. Traffic management
Traffic management is the organised control, regulation and guidance of road users to improve safety, traffic flow and the efficient use of roads. It can include traffic lights, road signs, road markings, lane controls, variable speed limits, diversions and directions given by authorised persons.
Traffic management may be permanent or temporary. Temporary measures are commonly introduced during roadworks, congestion, collisions, public events or other incidents. Drivers and other road users must follow the signs, signals and instructions applying at the location, even when they differ from the normal traffic arrangement.
