Have you ever noticed the board that instructs you to take the diverted route as there’s a construction going on the ahead curb? The urban development projects often disrupts the daily transport route and also the public transport services. However, with proper analysis and planning it is possible to smooth out this disruption.

But if you think these disruptions are not planned out beforehand then you are most certainly wrong. The divert board signs which you get or other preliminary measures taken is as a result of the Traffic Impact Assessment (TIA).

This assessment aids in regulating the essential amendments in the present infrastructure or commuting services if required due to the tendered development projects. The traffic movements of the specific location and adjoining places are assessed in the report thoroughly in order to avoid traffic congestion or any unforeseen accidents.

Let’s take a deeper look into this topic.

What is Traffic Impact Assessment?

It is basically a technical examination of traffic and safety issues that is or may be caused due to a proposed development project. The primary agenda of this investigation is to find out whether the upcoming project will cause an impact upon the efficiency and safety of commuting public.

It helps in generating a report that includes traffic management plans and measures that can minimize the traffic blockage. The TIA determines both physical impact and operations of transport system.

Primary Objective of Traffic Impact Assessment

It is a mandatory initiative of the Statement of Environmental Effects which must be included in the Development Application. The core intention of this report is to allow the state government and council take appropriate decisions regarding the traffic status affected from the development projects.

Essential submission documents

Now as the TIA report is an integral part of the Development Application, it must be submitted to the State Council. Along with this report, the related traffic module files are also needed to be put forward. The significant documents required for filing this report are –

  • Development Project’s details
  • Existing status of transportation
  • Procedures utilized to estimate traffic generation
  • Assessment of traffic safety risks
  • Summary table of traffic generation
  • Assessment of Cyclist and Pedestrian impact
  • Representation of traffic volume figures along with the Development Project’s assumption
  • Figures of traffic distribution in the affected area
  • Assessment of public transport impact


You would require the assistance from the professionals for understanding the magnitude of the proposed project. Since generating an extensive Traffic Impact Assessment report is complex. We recommend to seek out the expertise of traffic engineers for the successful creation of Development Application.

It is not just a formal initiation report for development projects but also essential for smooth traffic regulations. An elaborated TIA report will only smooth out the traffic congestion and help the general public to go about in their regular life.
