Need & purpose Need - Safety “…long delays for pedestrians, bicyclists and motorists wishing to cross the highway or for vehicles wanting to turn left onto or off of the highway. “ TSP Jan 2010 Purpose – Improve Safety Reduce the number and severity of motor vehicle crashes at this intersection. Maintain access to businesses, residential communities, schools, lodging, commercial and industrial developments and the alternate truck route for all users of the facility (Hwy US20)

1. Reduced wait time 2. Improved safety How does a roundabout compare to a signal? Year of Opening (2017) Average Delay/Vehicle 1. Reduced wait time CONVERTED TO ~ 15.2s ~13.9 s 2. Improved safety CONVERTED TO 78% < in injuries 48% < total crashes

Roundabouts reduce crashes Over 90% reduction in fatalities 76% reduction in injuries 35% reduction in total crashes Very little reported pedestrian and bicycle crash experience * NCHRP Report 572 Photo: Lee Rodegerdts

Navigating the roundabout Four things to remember when driving a roundabout. Slow down when approaching a roundabout. Circulate counter-clockwise around the circle. Yield to traffic in the roundabout. Vehicles in the roundabout have the right-of-way. Do not stop within the circular portion of the roundabout. Signs you might see. The yield sign tells drivers to yield to traffic already in the roundabout. Drivers should keep right of the center median when entering a roundabout. Roundabouts are designed for speeds between 15 to 25 mph. Drivers should look for pedestrians in marked crossings before entering or exiting a roundabout.

Summary Why roundabouts? Roundabout will be designed for… Safer for all users Lower peak hour and off-peak delay Community gateway opportunities Roundabout will be designed for… Passenger vehicles Pedestrians Bicyclists Freight
