The 2019 “Base Case” analysis indicates that the Elm Street / Pearsons St intersection would
continue to perform within capacity; however, the Elm Street / Diamond Street intersection
would most likely exceed its capacity prior to 2019 and therefore will need to be signalised by
this time. The movements expected to experience significant delays would be the northbound
right-turn movement from Diamond Street to Elm Street.

The analysis was revised to incorporate a traffic signal at the intersection of Elm Street and
Diamond Street to mitigate the impacts of traffic growth. The results of the revised intersection

analysis are presented in Table 5 below. The layout of the intersection adopted for the SIDRA
analysis for the signalised intersection is illustrated as Figure 6.
