Review the interface elements as shown in Figure 1. From the extracted folder, open Fundamentals.pthto launch Pathfinder with that model. Right-click pathfinder-fundamentals.zipand click Extract All. Open Windows Explorer and browse to the downloaded file. This provides some additional counter-flow movement to the model. Download the Pathfinder Fundamentalszip file. There are two occupant sources in the model (Lower and Upper) for agents to start at one of the levels and exit on the other level.

We set the Priority value of 'Walkers' to 1 to allow for them to more easily move past 'Standers' who will politely yield to 'Walkers' as necessary to let them pass. Within 70% of the population using escalators, 50% of the entire population will stand on escalators (Standers) and 20% are allowed to walk (Walkers). In this demonstration, 70% of the population will use escalators and 30% will use the stairs (Steppers). The simple model connects a lower level to an upper level by way of a set of up/down escalators on each side of a central set of stairs. This example model demonstrates a method within Pathfinder to model these percentages and difference in movement characteristics. In addition, some portion of the population will walk on an escalator and others will stand. In real-world pedestrian movement scenarios, different percentages of the population will use stairs or escalators.
