ROUNDABOUT SUMMARY • We all drive t hrough signals every day and are quit e familiar wit h t hem • Roundabout s are less common • Let ’s t ake a moment t o learn more about roundabout s
ROUNDABOUT - TYPICAL FEATURES
PRINCIPLES OF GOOD ROUNDABOUT DESIGN NCHRP Report 672 Roundabout s: An Informat ion Guide • Slow ent ry speeds and consist ent speeds • Adequat e capacit y and number of lanes • Smoot h channelizat ion • Accommodat ing design vehicles • Providing sight dist ance, visibilit y, and light ing • Int egrat ing pedest rian and bicycle feat ures
BENEFITS OF ROUNDABOUT • Improved Overall Safet y – 36% t o 60 % fewer t ot al crashes t han a signal – Reduct ion in crash severit y in general – Nearly 10 0 % reduct ion in fat al Crashes
• Reduced Delay – No st opping if no opposing t raffic
• Reduced Noise • Aest het ically Pleasing – Adapt able t o Local Cont ext
ROUNDABOUT - BICYCLE AND PEDESTRIAN FEATURES Crosswalk and t wost age crossing
