A doughnut layout automatically ensures what feature related to exit routes?

1. It limits access points to prevent congestion.

2. It provides a continuous exit route.

3. It reduces the number of entrances to maintain security.

4. It promotes diagonal circulation paths.

The correct answer is: It provides a continuous exit route.

A doughnut layout is characterized by its circular form, which inherently provides a continuous path that allows for clear and unimpeded exit routes. This layout ensures that all areas within the space are accessible and can be exited easily, allowing for a smooth flow of traffic as occupants move toward exits. This feature is particularly beneficial during emergencies, as it minimizes the risk of bottlenecks and allows individuals to exit the building quickly and efficiently. A continuous exit route helps facilitate a safe evacuation by ensuring there are multiple points from which occupants can leave the space without confusion or obstruction. The other options do not directly align with the inherent characteristics of a doughnut layout. For example, while a doughnut shape can help manage circulation, its primary strength lies in the provision of a continuous exit route rather than limiting access points or reducing entrances.
