3.2.2     ELM STREET (COOROY CONNECTION ROAD) / LAMONTS ROAD INTERSECTION

The anticipated development traffic movements at this intersection is up to 41vph total in each peak hour period
throughout the assessment period. The total background traffic anticipated in the base year 2018 at the intersection is in
the order of 1,492vph in the AM Peak and 1,546vph 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 2.7% in both the AM peak
and PM peak. In the design year 2028, the proportion of the development traffic is 1.9% in the AM peak and PM peak.
This is well below the general 5% threshold that triggers more detailed assessments. Notwithstanding, the TMR turn
warrants were examined for this intersection, for the traffic scenario of the base year 2018 only. Please refer Figure 3.3.
