Travel distance is used to determine which design aspects?

• A. Exit placement and width
• B. Elevator speed
• C. Roof material
• D. Window size

Answer: (A)

Travel distance is the length a person must travel along the egress path to reach an exit. Codes set a maximum travel distance to ensure people can reach safety quickly, so the design must place exits and size the egress paths accordingly. If exits are too far apart or corridors are too narrow, occupants could exceed the allowed travel distance or experience congestion, delaying evacuation. Roof material, window size, and elevator speed don’t directly determine or limit how far people must travel to an exit; those factors relate to other aspects of fire safety or building performance rather than the length of the egress path.
