POTENTIAL CONFLICTS

Some might argue that changing a signaled intersection to a round-a-bout might make the intersection less efficient because the capacity will decrease. However, round-a-bouts are designed to move traffic through them while allowing for the same capacity of traffic as prior to its installation while maintaining a slower speed and decreasing the times a driver must stop.

Location is a big factor in developing round-a-bouts. While adding a round-a-bout is up to the city/community and planners, they do require heavy construction. This makes round-a-bouts better suited for less dense traffic situations. Suburban cities and more rural communities might be better suited to take on round-about development than higher density cities, but it should not discourage developing round-a-bouts.

Cost

Moderate cost

Although the prices do range depending on the location and design of the round-a-bout, on average one round-a-bout is estimated at roughly $250,000. However, some designs can be as low as just under $200,000 and go up to roughly $500,000 per round-a-bout.
