Parsons Brinckerhoff: Deep Station Lift Study

 

Project title:
Deep Station Lift Study – PTV Viswalk Pedestrian Microsimulation Modelling

Contracting authority:
Transport for New South Wales, Australia

Branch/sector: Public Authority
Contractor

Project duration:
2 months

Project description:
Some of the proposed railway stations in Sydney may be located at such a depth (in excess of 40 meters from surface to rail level) that lifts will need to comprise the principal method of vertical transportation rather than escalators. PTV Viswalk was used to simulate the operation of deep railway station to demonstrate this dependence on lifts rather than escalators is a viable option.
Viswalk models were developed for concept design of deep station, which included train and pedestrian movements, lifts and ticket gates. Two lift and station layout options were assessed including:

  • Single lift option - two platforms located on the same level were linked to two central banks of 5 signal lifts
  • Double-stacked lift option - two platforms located on different levels were linked to one central bank of 5 double-stacked lifts

Various train arrival sequences were also modelled to test the operation of station in terms of pedestrian delay and queue at congested areas. Dynamic pedestrian routing function in PTV Viswalk was applied to mimic the complexity of way finding process when passengers selected the lifts and passed through the ticket gates.
The modelling results revealed that the pedestrian queues that form in front of each lift bank was manageable in both options. Passengers would experience shorter average travel time and less delay in the single lift option compared to the double-stacked lift option, due to better utilisation of lift capacity and less complicated way finding process for passengers for the single lift option.
