4-3 lanes Road Diets
Not just for bike lanes Road diets: reclaim street space for other uses
Road Diets and Traffic Operations

Roundabouts
Clearwater FL A roundabout is a type of intersection control
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 Separated sidewalks direct peds to crosswalks Splitter island Slow speed exit Truck apron Crosswalk 1 car length back Lots of deflection = slow speeds throughout Slow speed entry = yield Bend OR
Constrained entry slows drivers
Traffic Circles Can replace 4-way stops And beautify
