I Traffic Impact Report · 132007.2398

Do note that without the development traffic, in base year 2018 that during the AM peak the turn treatment CHR is
warranted. This is based on the forecasted base year 2018 traffic scenario without the development traffic.

Based on the analysis above and the small proportion of development traffic at the intersection (less than 5%) there are
no upgrades proposed to this intersection location.




3.2.3     ELM STREET / DIAMOND STREET INTERSECTION

The anticipated development traffic movements at this intersection consists of 58vph total during peak periods throughout
the assessment period. The total background traffic anticipated in the base year 2018 at the intersection is in the order of
2,456vph in the AM Peak and 2,261vph in the PM peak. The development traffic as a proportion of the total background
traffic movements at the intersection in the base year 2018 is less than 5%, being 2.6% in the AM peak and 2.9% in the
PM peak. In the design year 2028, the proportion of the development traffic is reduced to 1.9% in the AM peak and 2.0%
in the PM peak. This is well below the general 5% threshold that triggers more detailed assessments

Based on the small proportion of the development traffic (less than 5%) at the intersection, it is anticipated that the
development will not significantly impact on the performance of this intersection. As such, there are no mitigation
measures required at the intersection.
