The latest episode of the “Zero to 60” series produced by the Alabama Department of Transportation (ALDOT) provides viewers with an in-depth look at the benefits of roundabouts and why they’re becoming an increasingly common sight on roadways statewide.

Aaron White, ALDOT Southeast Region’s local transportation and special projects engineer, explained the mechanics of a roundabout on the show: “A roundabout is a circular intersection where traffic flows around a center island. Slow down as you approach and yield to your left. Once it’s clear, enter the roundabout and keep moving at a steady pace. Use your turn signal and exit safely.”
ALDOT noted that roundabouts aren’t just a new trend; they’ve been shown to significantly improve safety and traffic efficiency. According to White, roundabouts reduce serious crashes by up to 80 percent compared to traditional intersections. They also keep traffic moving smoothly, minimizing delays and reducing fuel consumption, noted White. “The data backs it up,” he said.
Another major benefit of roundabouts, explained ALDOT, is the positive impact on pedestrian safety. With crosswalks set back from the circle and lower vehicle speeds, drivers have more time to react, creating a safer environment for those on foot.
Visuals in the episode highlight pedestrians using crosswalks near roundabouts, emphasizing that these traffic designs are not only safer for drivers but for pedestrians as well. “Roundabouts improve safety for everyone, including people walking near the intersection,” White explained on the episode. “With all these benefits, it’s no surprise that roundabouts are showing up in more communities across Alabama,” White notes. “More are on the way, making our roads safer and more efficient for everyone.”
