Traffic modelling videos

Important information to note prior to watching traffic modelling videos

The videos are a visual representation of the technical traffic modelling of peak hour travel across each proposed bridge option, and includes the existing Grafton bridge and the surrounding local street network. The speed of the trips depicted in the video is quicker than actual times in order to highlight traffic flows on the Grafton and South Grafton network within a suitable timeframe for viewing by the general public.

Traffic is based on 2019 and 2049 peak travel time volumes (year of assumed opening and 30 years after the assumed opening of the new crossing of the Clarence River).

The modelling data includes the following assumptions:

  • Traffic volumes are based on forecast population growth for the Grafton and Clarence Valley area
  • Normal driver behaviours including lane changing, overtaking and merging as well as road network characteristics
  • The driver has the ability to choose either the existing bridge or the new bridge, based on previous travelling experience on the network.
