3.2.3     ELM STREET / DIAMOND STREET INTERSECTION

The anticipated future year, 2028, traffic volumes, including site traffic, are presented below in Figure 3-5.

AM Peak                                                  PM Peak
Hour                                                     Hour




Figure 3.5: Elm Street / Diamond Street intersection, 2028 AM and PM Peak Hour volumes, based on 2028 Traffic
Volumes adjusted for increased development due to site

Both in the future design year and the base development year, the development traffic volume as a proportion of the
background traffic volume is less than 5%, at a maximum of 4.5% in the 2018 PM Peak and 3.2% in the 2028 PM Peak.
Therefore the development traffic as a proportion of the existing background traffic at the intersection represents less
than the general 5% threshold requirement that triggers more detailed assessment.

Nevertheless the intersection was assessed using the SIDRA. The key outcomes from this analysis are shown below in
Table 3-4.
