8           Future Transport Demands
8.1         Assessment Years and Traffic Growth
To estimate the future traffic volume for the 2024 and 2034 scenarios, the annual growth rate for the
Council has been determined based on the following:

•    The forecasted population volume set out in Section 4.2 of Noosa Shire Economic Development Strategy
     2021-2030. For Noosa, the population growth between 2020 and 2041 is projected to be 0.8%.

•    The existing and projected demand for the transport network set out in Table SC3.1.7 of Council’s LGIP
     Planning Assumptions Tables.

•    For the Coastal Area (Noosa Heads), the existing and projected transport demand vehicle per day (vpd)
     data between 2021 (331,603) and 2031 (369,091) is projected to be 1.08%.

For conservativeness, an annual growth rate of 1.2% has been adopted, which accounts for the future
development and is considered on higher end, given this level of growth over a 12-year period would result
in significant improvements / changes to the transport network, noting additional road connections, allowing
for additional dispersion of existing traffic volumes.

As such, while the overall traffic may increase by 1.2% per annum, the traffic growth on an individual road
segment is expected to be less than this as traffic disperses onto the ultimate road network.

TTM has identified three assessment periods for the road network as follows:

Current Traffic Scenario

This scenario includes the 2022 traffic volumes modelled over the existing road network. This analysis has
been performed for both the AM and PM Peaks.

Opening Year (2024) Traffic Scenario

This analysis incorporates a 1.2% per annum increase in the background traffic volume for a period of 2 years
from the most recent survey. For the base case scenario, the existing road network has been analysed.

Design Horizon (2034) Traffic Scenario

This analysis incorporates a 1.2% per annum increase in the background traffic volume for a period of 12
years (10 years past opening year).

Based on the development transport demand estimates (Section 8), 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 Appendix D, with the respective diagrams identified as follows:
