Roundabouts
-
A roundabout is a type of intersection control Clearwater FL
-
A roundabout is not:
1. A New England style rotary, with large size & high speeds
Augusta ME
-
A roundabout is not:
2. A Washington DC style circle, with traffic signal controls
Washington DC
-
Why roundabouts are safer for all users:
• Slow speed:
Deflection, truck apron, splitter islands, “reverse super”
• Reduced conflicts
• No left turns
• Yield on entry
CRF (all users):
• About 54% overall
• 27% pedestrian crashes
• Up to 76% fatalities and serious injuries
-
Essential roundabout characteristics
Slow speed entry = yield
Slow speed exit
Truck apron
Splitter island
Crosswalk 1 car
length back
Lots of deflection = slow
speeds throughout
Separated sidewalks
direct peds to crosswalks
Bend OR
-
Constrained entry slows drivers
-
Traffic Circles Can replace 4-way stops
And beautify
