Question

Why are traffic circles considered safer than traditional intersections?

A. All traffic moves in one direction
B. Pedestrians are not allowed at circles
C. There is less traffic than in traditional intersections
D. The speed limits are lowered

Answer 1

Traffic circles are considered safer than traditional intersections mainly because all traffic moves in one direction, reducing conflict points and potential for high-speed collisions.

Step-by-step explanation:

Traffic circles, or roundabouts, are considered safer than traditional intersections for several reasons, but one of the key safety features is A. All traffic moves in one direction. This design helps to reduce the potential conflict points and the likelihood of high-speed collisions since all vehicles are moving in the same circular flow. Contrary to option B, pedestrians can sometimes be present at roundabouts but they are generally provided with crosswalks that are set further back from the circle, reducing the likelihood of an accident. As for option C, the amount of traffic does not necessarily determine safety, and for option D, while speed limits can be lower in traffic circles to enhance safety, the key design feature contributing to safety is the one-way nature of travel within the circle.
