147th and Ravinia-June 19, 2018

147th and Ravinia July 6, 2018


The Village of Orland Park’s first roundabout will soon be constructed at the intersection located at 147th and Ravinia Avenue, just east of Village Hall.

In addition to the enhanced functionality and safety, aesthetics will be taken into consideration with greenscapes and beautification of the new roundabout.


A roundabout is a circular intersection where drivers travel counterclockwise around a center island. There are no traffic signals or stop signs in a roundabout.



1) Observe all Rules of the Road.

2) Slow down.

3) Yield to pedestrians and bicyclists at the
crosswalk as you enter.

4) Yield to circulating traffic from the left before entering.

5) Enter the roundabout when there is a safe gap in traffic.

6) Yield to pedestrians and bicyclists at the crosswalk
as you exit at your desired street.

Motorists are required by law to move over when
an emergency vehicle approaches. In the case of
roundabouts, motorists must clear a roundabout if
they hear (or see) an emergency vehicle approaching.

Further Information:





30-50% increase in traffic capacity.


Less idling for cars, less gas being burned into the atmosphere, better fuel economy.

  • Provide landscaping and green space opportunities.
  • Crosswalks included for pedestrians and bicyclists.


- All vehicles travel in same direction. 

-Vehicles never cross paths, which reduces
number of serious crashes.

-Slower vehicle speeds give drivers more
decision making time.

-Roundabouts eliminate head-on and
high-speed right-angle collisions.

-No traffic lights to install and maintain.

-There are 75% fewer conflict points in roundabouts
than in traditional intersections (see diagram below). 


-Look to your left before entering roundabout.

-Vehicles already in the roundabout have the right-of-way. 

-If there is no traffic in the roundabout, proceed slowly into the circle.

-Typical speed within a roundabout is 15-20 mph.
