This trip segmentation was incorporated within the SIDRA analysis documented in the Revised Traffic
Report (17th September 2019).

Comparison to Previous Approval and Revised Traffic Report (Sept 2019)
The difference in peak hour total trip generation between the Previous Approval (MCU12/0051) and the
Proposed Development is summarised in Table 9.

The Proposed Development is expected to generate approximately 367 fewer trips that the Previous
Approval in the Saturday noon peak hour.

The Proposed Development is also expected to generate fewer trips to the Previous Approval in the
Thursday PM peak hour. As such, the Proposed Development is expected to have comparable or lesser
impact on the surrounding network than the traffic assessment associated with the Previous Approval.

It is important to note that no external road network upgrades were required as part of the Previous
Approval over the site. Given the Proposed Development is expected to generate lower traffic volumes
that the Previous Approval, no road network upgrades are considered to be required to support the
proposed development.

This was also supported by the findings of the SIDRA assessment documented in Section 11 of the
Revised Traffic Report (dated 17th September 2019).

The difference in adopted peak hour total trip generation between the Revised Traffic Report
assessment and the currently Proposed Development is summarised in Table 10.
