Methodology
Act
Assessment was undertaken for the 4 sections that make up the Golden Mile (GM):
1. Lambton Quay
2. Willis Street
Information
3. Manners Street
4. Courtenay Place
Official
Three criteria was assessed:
the
1. Pedestrian level of Comfort
2. Pedestrian delay
3. Bus stop occupancy
under
Released
1982
Methodology
Act
Criteria 1 - Pedestrian level of Comfort assessed using the Transport of London
Pedestrian Comfort Guidance
Information
1. Step 1 – Divided GM into sections based on footpath width changes (Topographical
survey undertaken by project team)
2. Step 2 – Categorise each section into 1 of 5 area
Official types, all sections were
categorised as High Street (Areas dominated by retail and food and drink)
the
3. Step 3 – Identify street furniture on each section that would reduce level of comfort
4. Step 4 – Obtain pedestrian counts for the peak and average hour by section (2016
Active Mode Visualisation counts scaled up using March Monitoring data)

Released
1982
Methodology
Act
Criteria 2 - Pedestrian delay – quantification of pedestrian delay along and across the
GM using Pretty’s Method outlined in the HCM
Information
1. Step 1 – Identify all legal crossing opportunities for pedestrians
2. Step 2 – Categorise each into signalised, unsignalised or zebra crossings
3. Step 3 – Modelled signal data was used to determine proposed signal timings for
Options 1 to 3 (proposed signal timings were co
Official nstant for each option)
4. Step 4 – Delay at unsignalised/zebra crossings were estimated (across=20s and
the
along=10s)
5. Step 5 – Estimate number of pedestrians crossing at each location (scaled ped
volumes were used, 50% of the along volumes were used for the ped crossing
across)

Methodology
Act
Criteria 3 - Bus stop occupancy – quantifying the impacts of bus stop occupancy on
walking pedestrians
Information
1. Step 1 – Determine arrival rate of patrons (an arrival rate survey was done at two
stops on Lambton Quay and Courtenay Place, one on each side of the road)
2. Step 2 – Determined boarding rates per stop along the GM using snapper data
Official
3. Step 3 – Assumed a max queue length on 10m to determine width of queuing
patrons (personal area assumed at 1m2 pp)
the
4. Step 4 – Based on the above calculated available walking space per option
Note: Arrival rate at Manners Street = Courtenay place and Willis Street = Lambton quay

Increase in footpath widths improved an already good overall Level of Comfort along the GM

Increases in footpath width along Willis Street and Lambton Quay have the greatest impact on LoC
Changes to Manners Street are minimal and will have a negligible impact on pedestrian LoC

Option 2 and 3 along Lambton Quay have more side roads converted to pedestrian areas removing
delay along the GM
the
Side road closures and signal time reduction along Willis Street and Manners Street will result in a
reduction in pedestrian delays
Option 3 scored slightly better than Option 2 along Courtenay Place, due to Tory Street becoming a
ped area – however the improvement did not warrant a different score

The increase in footpath width along Lambton Quay and Courtenay Place will increase available area
for passing pedestrians
the
Option 3 provides for an increase in footpath width along Willis Street increasing available waiting
space at bus stops
Changes to Manners Street are minimal and will have a negligible impact on pedestrian LoC
