intersection on Goulburn Street eastbound and westbound
- Traffic approaching the Goulburn Street/Pitt Street intersection
on Pitt Street northbound.
Demand is close to capacity at work site C1: Wentworth Avenue
(A: Oxford Street intersection) (LoS E) whilst demand exceeds
capacity at C2: College Street (E: Park Street intersection).
Traffic queues originating at the following intersection approaches
propagate to upstream intersections, reducing intersection,
corridor, and network performance:
- Traffic approaching the College Street/William Street
intersection on College Street northbound and William Street
westbound
- Traffic approaching the Wentworth Avenue/Oxford
Street/College Street intersection on Oxford Street westbound.
Demand is close to capacity at work site F1: Macquarie Street
(A: Bent Street intersection).
Traffic queues originating at the Macquarie Street/Bent Street
intersection propagate to upstream intersections to the north,
south, and west, reducing intersection, corridor, and network
performance.
The model-predicted results in Table 6-3 and Table 6-4 show that there are existing
capacity issues throughout the proposal footprint resulting in long delays and
extended traffic queue lengths in certain locations. These issues are likely to worsen
in the future as a result of the loss of overall traffic capacity created by the traffic
priority changes introduced under the other Access Strategy projects as considered
below in section 6.1.3.
The two poorest performing intersections in the proposal footprint are C2: College
Street (E: Park Street intersection) and F1: Macquarie Street (A: Bent Street
intersection). They are both operating at or above capacity. The proposal includes
schemes that would modify the approach lanes to these intersections, benefiting
localised and wider network performance. Specifically:
Work site C2: College Street (E: Park Street intersection) would be improved by
reconfiguring College Street northbound on the approach to this intersection
Work site F2: Macquarie Street (A: Hunter Street intersection) would be
improved by reconfiguring Macquarie Street northbound of this intersection
under the work proposed at work site F1: Macquarie Street.
6.1.3 Potential impacts
Traffic, transport and access impacts during construction
As described in Chapter 3, the aim is to construct the proposal in a timely and
efficient manner, considering the need to:
Maintain access for all travel modes to, from, and through the city centre
Minimise the impacts to the performance of the city centre road network,
particularly during peak periods.
