A roundabout is a traffic calming feature used as an alternative to stop signs. There are increased safety benefits with roundabouts versus stop control or signal control. Due to the low-volume roadways in the area, traffic analysis and models have shown that the mini roundabout functions very well. It helps slow traffic while keeping it flowing as drivers traverse around the central island.
Another benefit is that roundabouts fit within primarily the existing footprint of a smaller intersection, so this limits any adjacent property impacts to be minimal.
Roundabouts also maintain truck turning movements if a bigger truck needs to turn through the intersection by using the center island. All islands would be raised with a truck apron curb. So, it’s mountable, but not desirable for a passenger vehicle to travel on.
