since the building is only represented by the travel route distance, the number <strong>of</strong> stairwells, the<br />
exit door width, and the geometry <strong>of</strong> the stair. Congestion occurs only at the doors or stairwells.<br />
The equations below make up the calculations made by FPETool to provide egress times (as<br />
shown in Figure A.1).<br />
