WHY USE A ROUNDABOUT?
- SafetyRoundabouts have
been shown to reduce fatal and injury accidents as much as 75%. The
reduction in accidents is attributed to slower speeds and reduced
number of conflict points
(See Figure 2)
- Low MaintenanceEliminates
maintenance costs associated with traffic signals which amount to
approximately $3,500 per year per intersection. In addition, electricity
costs are reduced with a savings of approximately $1,500 per year
- Reduced DelayBy yielding
at the entry rather than stopping and waiting for a green light, delay
is significantly reduced.
Intersections with a high volume of left turns are better handled
by a roundabout than a multi-phased traffic signal.
- EnvironmentalA reduction
in delay corresponds to a decrease in fuel consumption and air pollution.
- AestheticsThe central
island provides an opportunity to beautify the intersection with landscaping.
HOW TO DRIVE A ROUNDABOUT
As you approach a roundabout there will be a YIELD sign and dashed
yield line. Slow down, watch for pedestrians and bicyclists, and be
prepared to stop if necessary. When you enter, yield to circulating
traffic on the left, but do no stop if it is clear.
A conventional roundabout will have ONE-WAY signs mounted in the center
island. They help guide traffic and indicate that you must drive to
the right of the center island. Upon passing the street prior to your
exit, turn on your right turn signal and watch for pedestrians and bicyclists
as you exit.
Left turns are completed by traveling around the center island.
