The results displayed in Table 4-3 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 intersections. Therefore, it can be concluded that the development will not adversely
impact the performance of the Hofmann Drive / Rene Street roundabout in 2022.
The results for the analysis of the background traffic and with development traffic scenarios for
the Hofmann Drive / Rene Street roundabout in the future design horizon year (2032) have been
summaries in Table 4-4. Detailed SIDRA outputs have been included in Appendix D.
