What Are Traffic Impact Assessments, And Why Are They Important?

A traffic impact assessment (TIA) is used to assess potential traffic impacts. Historically, traffic impact assessments consultants Canberra have been used to determine expected traffic increases and evaluate the effects on adjacent roads, intersections, and driveways. The evaluation base was traditionally the car and the necessary improvements to the car. 

However, traffic impact assessments in Canberra are now being used more in sustainable development with policy initiatives to promote a more integrated approach to transportation planning and consider public transportation, pedestrians, and cyclists. 

The safe and efficient management of road networks is the responsibility of road authorities. Land use developments create traffic movements as people move to, from, and even within the settlement. Without a clear picture of the type of traffic movements or their range, time and location, there is a risk that this traffic movement contributes to safety concerns, unforeseen traffic jams or other—problems where development is connected to the road network or elsewhere on the road network.


To counteract the above, licensing authorities often require that a “traffic study support a development proposal”, a “traffic impact assessment”, or a “traffic statement. The TIA is a detailed process carried out by the traffic impact assessments consultants Canberra against which the traffic flows. The effects of the planned development must be objectively determined and measured. The decision of the TIA team rests with the developer. 

Specialized traffic or planning consultants or highway construction engineers are recommended, especially for larger or more complex projects. For more minor proposals, any professional with the appropriate experience who has experience or is familiar with traffic generation rates can prepare a TIA.

  •  The TIA process includes: 

  •  Evaluating existing conditions or essential traffic volume (vehicles and pedestrians) in the development area and the surrounding area;


  • Forecast of traffic flows to and from the development at significant crossings in the surrounding area (according to the type of vehicle, daily / weekly movements, in the construction preparation, construction and operation phases); 

  •  Assessment of the importance and effects on the existing transportation network; 

  •  Assessment of changes needed to accommodate additional traffic and reduce adverse effects. 

  •  After reviewing the TIS and construction request, technical officers from the planning department submit a recommendation to the board. 

  • Technical officials from the planning department evaluate the TIS and the merits of the construction request. 

When evaluating the TIS, the Ministry of Planning may seek advice from legal advisers or other suitably qualified persons or organizations, particularly technical officials from the Department of Road Transport of the Ministry of Construction and Engineering. 

The Traffic Impact Assessment (TIA) is a technical examination of traffic problems and safety concerns associated with specific development. The TIA report’s main goal is to see if a specific action plan will have an impact on the safety and efficiency of nearby roads. Traffic impact assessments in Canberra will help reduce traffic jams, improve security, ensure proper access, and mitigate project impact.
