QUIZ: Advantages of Roundabouts

Roundabouts can provide numerous benefits over traditional intersections and have quickly become a regular sight around Florida. What do you think are some advantages of roundabouts? Take this quiz to test your knowledge.
1. Compared to traditional intersections, roundabouts may increase traffic capacity by up to __, according to FHWA.*
- 10%
- 20%
- 30%
- 50%
Correct!

Studies by the Federal Highway Administration have found that roundabouts can increase traffic capacity by 30 percent compared to traditional intersections.

2. How do roundabouts save taxpayers money?*
- Roundabouts have no traffic signals and no associated maintenance.
- Roundabouts still operate during power outages, eliminating the need for police to direct traffic.
- Roundabouts limit the severity of collisions
- All of the above
Correct!

Roundabouts are typically safer for pedestrians since they only have to cross one direction of traffic at a time. Crossing distances are relatively short and traffic speeds are lower than at traditional intersections.

3. Compared to regular intersections, roundabout crashes may result in __ fewer fatalities, according to FHWA.
- 90%
- 75%
- 60%
- 45%
Correct!

Not only do crashes in a roundabout result in fewer fatalities, but they also cause 75% fewer injuries. A roundabout’s design reduces crash severity by requiring approaching vehicles to slow down before entering the intersection. Left-hand, right-angle (T-bone), and head-on crashes are virtually eliminated.

5. Which has fewer vehicle-to-vehicle conflict points, a typical four-legged roundabout or a typical four-legged traditional intersection?*
- Roundabout
- Traditional
Correct!

A typical four-legged roundabout only has eight vehicle-to-vehicle conflict points, while a typical four-legged traditional intersection has 32 vehicle-to-vehicle conflict points. Fewer conflict points mean fewer opportunities for a crash to occur.
