What is the route of travel used to determine measured egress distances in code enforcement, defined as down the center of a straight corridor with a 1-foot radius around each corner?

What is the route of travel used to determine measured egress distances in code enforcement, defined as down the center of a straight corridor with a 1-foot radius around each corner?

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

Answer: (B)

Measuring egress distances uses the common path of travel. This portion of the egress route is the section from the most remote point of occupancy to the point where paths diverge into separate exits, and the distance is taken along the centerline of corridors. At corners, a 1-foot radius is added to round the turn, so the measurement more accurately reflects actual walking distance. This approach provides a consistent, conservative way to compare facilities against code requirements, regardless of furniture or wall configurations. The other terms describe different parts of the egress system: an exit leads outside, exit access is the portion toward an exit, and a horizontal exit is a doorway through a fire barrier within the same floor to another area.
