Figure 3: Hilton Terrace/Ernest Street Sidra Layout – PM Peak




In the AM cases, the layout includes a short right turn lane from the Ernest Street approach. This matches the practical
intersection operation and was used as a calibration tool to match the Sidra intersection performance with the surveyed
intersection performance.

All default parameters were used with the exception of gap acceptance and follow up headway in the AM cases. This was
changed from the default 7 and 4 seconds to 6.5 and 3.5 seconds respectively to match the Sidra intersection
performance with the surveyed intersection performance.

In the PM cases the Sidra intersection performance generally matched the surveyed intersection performance without
the short right turn lane and changes to the gap acceptance/follow up headway.

The results of this analysis are provided in Table 1 and Sidra files have been provided with this assessment.
