Frequently Asked Questions
Question: There was just a signal installed, why are you replacing the signal with the roundabout?
Answer: A roundabout is much safer than a conventional signalized intersection. Safety for all modes of travel is improved with intersections with roundabouts. One benefit is an overall reduction in vehicle speed while still accommodating all traffic movements. Also, the number of vehicle-to-vehicle conflict points decreases from 32 to 8 for intersections with single lane approaches, as shown in the graphic below. Head-on and high-speed collisions are virtually eliminated.
• More than 90% reduction in fatalities
• 76% reduction in injuries
• 35% reduction in all crashes
Reduces emissions and fuel consumption
• Efficient during both peak hours and other times
• Typically less delay
• Fewer stops and hard accelerations, less time idling
• No signal equipment to install, power, and maintain
• Require less right-of-way than traditional intersections
• Often less pavement needed
Improves the area’s look
• Signal wires, poles and ground equipment are removed
• Center of roundabout used for landscaping, fountains, public art, etc.
Question: How will large trucks be accommodated?
Answer: Roundabouts are designed to accommodate the turning movements of a tractor trailer rig. To accommodate the sweep of the trailer wheels as it makes its way through the roundabout, a truck apron is constructed around the inside of the circulating roadway. The apron is made of a different material or is colored differently in order to distinguish it from the circulating roadway and make it clear that the truck apron is not intended to be driven on by smaller vehicles.
Question: What is the difference between a roundabout and a traffic circle?
Answer: Traffic circles are much larger than a roundabout and often have stop signs or signals within the circular intersection. Roundabouts are smaller and vehicles have to yield before entering. Roundabouts typically operate at relatively low speeds (<25 MPH) while traffic circles allow higher speeds (> 25 MPH). Roundabouts restrict pedestrians from entering the central island while some traffic circles allow pedestrians to cross to and from the central island.
Question: How should drivers yield to emergency vehicles?
Answer: If you have not entered the roundabout, pull over to the right and allow the emergency vehicle to pass. If you have already entered the roundabout, continue to the closest exit and pull over once you are beyond the splitter island to allow the emergency vehicle to pass. Never stop in a roundabout.
Question: Should I stop inside the roundabout to let someone in?
Answer: You should not stop after crossing the yield line and are actually in the roundabout circle. However, you may slow down so a safe gap becomes more obvious to the driver wanting to enter the roundabout.
