Traffic Impact Assessment


A TIA is a study which assesses the traffic and safety implications relating to a specific development and are often required by Council during the Resource Consent process. These studies vary in their range of detail and complexity depending on the type, size and location of the development. The main functions of TIA study are:

  • To determine the existing traffic condition, future conditions without the development, and future conditions with the development in place;
  • To estimate the traffic likely to be generated by the proposed development;
  • To assess the impact of additional traffic on the existing and future road network system;
  • To assess parking provisions and parking manoeuvring space
  • To identify roadway improvements and changes in the site plan of the proposed development necessary to minimize

We have been developing parking management plans for various line haul depots and swept path analysis curves for residential and commercial dwellings.
