Road diets: reclaim street space for other uses

Not just for bike lanes

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
