           5. Sidra Analysis of Scenarios

           TTM have analysed the above scenarios in Sidra 6.1 and Sidra 7.0. There is no difference in the outputs
           between these versions for the scenarios analysed. Table 3 summarises the worst DOS and delay/LOS/queue
           for right turn from Holts Road. The Sidra models are attached to this assessment. The approach grade on Holts
           Road is set to 0% in all scenarios.

           Table 3 shows that a range of potential operational scenarios for the Myall Street/Holts Road intersection. This
           Table shows the Myall Street/Holts Road intersection is unlikely to exceed capacity (i.e. DOS >100%) in any
