Road safety and traffic

Roads and traffic monitoring

State road network

The State Government through the Department for Planning, Transport and Infrastructure manages around 25% of South Australia's total road network, including:

  • 13,000 kilometres of sealed roads
  • 10,000 kilometres of unsealed roads.

Local Government is responsible for maintaining 75,000 kilometres of local roads.

How traffic on State roads is monitored

Traffic volume figures estimate the number of vehicles on roads maintained by the state government. They are used to help manage, maintain and improve the traffic network. The two main measures are:

  • annual average daily traffic estimates
  • commercial (heavy) vehicle estimates.

Estimates of traffic volumes for metropolitan roads and rural roads are available as a series of maps.

Maps of roads managed by State Government

These documents provide information on roads maintained by the Department of Planning, Transport and Infrastructure.

The PDF documents below have been designed to print at A1 size. Use the print scaling options of Acrobat Reader to reduce the map to A2 or A3 page sizes.

Transport corridors

Transport corridors managed by the state government, including public transport, freight, bicycle, pedestrian and car movements, have an important role in achieving the state's goals.

The draft document A Functional Hierarchy for South Australia's Land Transport Network (9.3 MB PDF) guides the use of all transport corridors for which the state government is responsible.

It provides a clear picture of the roles individual transport corridors need to perform to achieve the broader goals and targets identified in South Australia's Strategic Plan and the Planning Strategy, including The 30-Year Plan for Greater Adelaide.
