Which term describes the route within the building used to determine the distance occupants must travel to reach an exit?

• A. Common Path of Travel
• B. Exit Access
• C. Exit
• D. Horizontal Exit

Answer: (A)

Common Path of Travel describes the portion of the egress route that is shared by occupants as they move toward an exit. This segment is the route used to determine how far people must travel to reach an exit, because it represents the portion of the journey that all occupants must traverse before any path splits to different exits. The distance is measured from the farthest occupied point to where two or more exits diverge; only the portion up to that divergence is the common path of travel. Distances beyond that point vary depending on which exit is chosen, so they aren’t part of the common path. Other terms refer to different parts of the egress system: exit access is the route from occupants to the entrance of an exit, the exit is the actual means of egress to the exterior or public way, and a horizontal exit is a protected connection between adjacent occupancies on the same floor. They describe other aspects of moving people to safety, not the shared route used to calculate travel distance.
