With these allocations set, Transport for NSW developed a multimodal traffic model
to consider and identify how the city’s roads would be impacted due to the
implementation of Access Strategy over the coming years. The model also
considered the demand introduced from other major developments such as
Barangaroo, the Alfred, Pitt, Dalley and George Street (APDG) development and the
Sydney International Convention, Exhibition and Entertainment Centre Precinct
(SICEEP) (refer to Table 6-33).
The model outputs identified the congestion pinch points across the city centre.
These represented the locations where the road network would not cope with existing
or future traffic volumes regardless of whether the key Access Strategy projects
progress or not.
The list was long as many of the city’s streets were shown to either currently operate
at or above capacity. Consequently, the focus was on identifying the key locations
where the improvements would most benefit the city centre over the coming years in
light of the planned changes introduced by the Access Strategy. Consequently
Roads and Maritime in collaboration with Transport for NSW identified that:
Improvements along certain streets are a priority to enable delivery of the key
Access Strategy projects
Certain streets are at a critical point in the road network (ie they are heavily
congested during the peak periods and would result in grid lock if they were not
improved under this proposal); this is compared to other streets that are near
capacity but would still function in the future once the Access Strategy projects
were implemented
Certain streets would indirectly benefit from improvements along other streets,
but it is sufficient not to improve their capacity at this point in time.
As a result the 17 pinch points in Table 2-2 were identified for improvement under
this proposal.
Table 2-2
Key pinch points
Key pinch point Reason for its selection (see further explanation in Table 2-1)
Precinct 1: north-west
NW1: Kent Street
Due to its multi-modal function parallel to the central spine
NW2: King Street
Precinct 2: retail
R1: Park Street
Due to its multi-modal function across the central spine
As it is a congestion pinch point and due to its function for bus
priority in the city
R2: Market Street Due to its multi-modal function across the central spine
R3: Sussex Street Due to its bypass function to the north, south and west
R4: Clarence Street Due to its function for bus priority out of the city
R5: York Street Due to its function for bus priority into the city
Precinct 3: southern
S1: Sussex Street Due to its bypass function to the north, south and west
S2: Goulburn Street As it is a congestion pinch point
