Why are roundabouts considered safer than traditional intersections?

Roundabouts are considered safer than traditional intersections primarily because they eliminate head-on collisions. In a roundabout, traffic flows in a circular pattern, with vehicles merging and yielding rather than coming to a complete stop and facing oncoming traffic. This design significantly reduces the likelihood of dangerous collision types, such as T-bone or head-on crashes, which are more common at traditional intersections where vehicles may approach each other from different directions at higher speeds.

Additionally, the lower speeds at which vehicles navigate roundabouts promote safer encounters. Traffic in a roundabout generally moves in the same direction, which minimizes the chances of severe accidents. This aspect, combined with the continuous flow of vehicles, contributes to a more predictable driving environment, enhancing overall roadway safety.

While faster exits, additional signage, and vehicle access restrictions can be factors in traffic management, they do not directly address the critical issue of collision prevention in the way that the design of roundabouts does. The fundamental aspect of reducing the potential for head-on collisions is key to understanding the safety benefits of roundabouts compared to traditional intersections.
