The results presented in Table 4-4 indicate that the roundabout will theoretically operate within
the practical capacity of a roundabout (DoS<0.85) for both the background traffic and with
development traffic scenarios. All delays are within the acceptable limits, with all legs scoring LoS
A. Queues were found to also be within acceptable limits and are not anticipated to impact the
surrounding intersection. Therefore, it can be concluded that the development will not adversely
impact the performance of the Hofmann Drive / Rene Street roundabout in 2032.
It can be concluded that the development will, theoretically, not adversely impact the performance
of the Hofmann Drive / Rene Street roundabout in 2032.


4.5.2   NORTHERN SITE ACCESS
The SIDRA Intersection software has been used to assess the performance of the Hofmann Drive
/ Northern Access intersection as a single site. The layout of the Hofmann Drive / Northern
Access intersection is shown in Figure 4-4.
