Base Year (2025) Traffic Scenario

This analysis incorporates a 1.2% per annum increase in the background traffic volume for a period of 4
years from the most recent survey. For the base case scenario, the existing road network has been analysed.

Base Year (2025) Traffic Scenario + Earthworks Traffic

Based on the development transport demand estimates (Section 1), traffic network diagrams have been
prepared showing traffic movements on the roads/intersections surrounding the development site for each
of the above scenario’s future year cases. These network diagrams are included in Attachment B – Network
Diagrams with the respective diagrams identified as follows:
    Traffic Network Diagrams 1: 2022 Survey Traffic Volumes

    Traffic Network Diagrams 2: 2025 Base Case Traffic Volumes (Applying 1.2% Growth)

    Traffic Network Diagram 3: 2025 Base + Earthworks Traffic Volumes
     -    This has been calculated by adding estimated Bulk Earthworks traffic volumes to the 2025 Base
          scenario.

It is noted that there will be minor light vehicle traffic associated with on-site management and equipment
operators, however, this will be limited to 4 – 6 personnel who will travel outside of haulage times.
