           Figure 3 shows the estimated 2029 PM traffic movements at the Myall Street/Holts Road intersection based
           on these changes.

           Scenario 4: Gap Acceptance and Follow Up Headway of 6 seconds and 3.5 seconds respectively

           In this scenario, the Sidra default critical gap acceptance will be reduced from 7 and 4 seconds respectively to
           6 and 3.5 seconds respectively. These values are still higher than identified in Austroads Guidelines and the
           Sidra User Guide for a two lane two way road. Whilst applying these alternative values, the following input
           data is still considered to be conservative:

                   Heavy vehicle percentage;
                   Traffic growth rates;
                   Base traffic volumes;
                   Traffic generation of industrial land use;
                   Fast food traffic generation; and
                   Shared trips.

           Scenario 5: All Alternative Values in Table 1

           In this scenario all alternative values from Table 1 will be used, including:

                   a critical gap acceptance and follow up headway of 6 seconds and 3.5 seconds respectively; and
                   2014 base volumes for the ‘upgrade option’;
                   0.4vph/100m2 GFA for industrial traffic; and
                   15% shared trips for fast food and service station traffic.
