How do you test the architectural design of the pedestrian facilities at Lausanne railway station?
A complex system of subterranean hallways
The canton of Vaud, the metro provider TL and Swiss Federal Railways SBB asked the ETH Institute for Transport Planning and Systems to conduct a study and to analyse the proposed construction plans. That’s where we came in. We used the pedestrian simulation software PTV Viswalk to test the architectural design and to verify whether all pedestrian flows could be managed without delays and with appropriate levels of service. Because of the crowded rush hour and dense timetable in Lausanne as well as the extremely limited underground space in the station vicinity, the simulation model consisted of a complex architectural system of subterranean hallways, ramps and crossings, as well as an origin-destination matrix with roughly a thousand cells. The model further featured over one hundred origin and destination points as well as an intricate underground tunnel system with dozens of hallways, ramps and crossings.
