Pendleton Roundabout

Community Information
Pendleton is a town in Fall Creek Township, Madison County, Indiana. It is part of the Anderson, Indiana Metropolitan Statistical Area. The population was 4,253 at the 2010 Census.

The roundabout being installed at the intersection of State Road 38 and County Road 300 West will be the first in Madison County, Indiana. This traffic enhancement will turn a once dangerous two-way stop into a more safe and navigable intersection for pedestrians and vehicles alike.

Safety Information   The Benefits
Did you know, modern roundabouts are the safest at-grade intersection?

They move traffic safely and efficiently through an intersection due to slower speeds, fewer conflict points (see diagram below), and easy decision-making.
 

Increased capacity - reduced delay:
There is a 30-50% increase in traffic capacity, and since traffic is always on the move, there is less delay.

Environmental:
Fewer idling cars reduces pollution and fuel usage - and because there are fewer starts and stops, intersections are far less noisy.

Lower Maintenance Costs:
Because roundabouts do not require traffic signals, there is no equipment to be installed or repaired. This equates to an average saving of $5,000 per year. Also, the average service life of a roundabout is 25 years versus 10-20 years for a signalized intersection.

Aesthetics:
Roundabouts improve the visual quality and character of an intersection through landscaping.

Consider this:
In 2004, the Institute of Transportation Engineers estimated that if only 10% of the estimated 265,000 intersections with signals in the United States were converted to roundabouts, annual vehicle delays would decrease by eight million hours and fuel consumption would be reduced by more than five million gallons.

 

Conflict Points
 

Studies show that roundabouts provide a 90% reduction in fatal crashes, 76% reduction in injury crashes, 30-40% reduction in pedestrian crashes, and a 10% reduction in bicycle crashes.

Slower vehicle speeds (under 25 mph) mean drivers have more time to judge and react to other vehicles and pedestrians, there is a reduction in the severity of crashes, and pedestrians are safer.

 
   
Roundabout VS Traffic Circle
FEATURE
MODERN ROUNDABOUT
TRAFFIC CIRCLE
Control at entry
Yield at entry (yield to circulating traffic)
Stop, signal, or yield to entering vehicle
Operational characteristics
Vehicle must choose exit upon approach, minimizing weaving within the roundabout to exiting only
Weaving is unavoidable and weaving sections are provided to accommodate conflicting movements
Deflection
Large angle at entry creates deflection to control speed through the roundabout
Angle likely to be minimal, allowing higher entry speeds
Speed
Low speeds (less than 25 MPH)
Higher speeds (greater than 25MPH)
Circle diameter
Smaller diameter improves safety by forcing slower circulating speeds
Large diameters allow higher circulating speeds
Pedestrian crossing
No pedestrians allowed in central island
Some traffic circles allow pedestrians to cross into central island
Splitter island
Required
Optional
Parking
No parking within or close to the yield line
On larger traffic circles, parking is sometimes allowed within the circulating roadway

Navigating a Single-lane Roundabout   Navigating a Multi-lane Roundabout
     

As you approach the roundabout, you will see a yellow “roundabout ahead” sign with the advisory speed limit. (See sign below)

Slow down as you approach the roundabout, and watch for pedestrians in the crosswalk.

Continue toward the roundabout and look to your LEFT as you near the yield sign and dashed yield lane at the entrance to the roundabout. YIELD to the traffic already in the roundabout.

Once a gap large enough for you and your vehicle appears, enter the roundabout and proceed to your exit. If there is no traffic in the roundabout when you approach, you may enter WITHOUT having to yield.

Look for pedestrians and use your turn single to indicate your intention to exit.

What about trucks, R.V.'s or vehicles with trailers? Roundabouts are designed to accommodate vehicles of all sizes, including emergency vehicles, buses, farm equipment, and semi-trucks. A special “truck apron” around the central island acts as an extra lane for large vehicles. The back wheels can ride up on the truck apron, allowing the large vehicle to easily complete the turn, while discouraging use by smaller vehicles. In multilane roundabouts, because large vehicles may need extra room to complete their turn, drivers should give special consideration to these vehicles and never ride adjacent to large vehicles in roundabouts.

 

 

In multi-lane roundabouts, you will see two signs as you approach. The yellow “roundabout ahead” and a black and white “lane choice” sign. You MUST choose your lane prior to entering the roundabout.

You choose your lane the same way you would a traditional intersection. To go straight or right, get in the right lane. To go straight or left, get in the left lane. Drivers can also make U-turns from the left lane.

Once you have selected your lane, watch for pedestrians in the crosswalk as you approach the roundabout.

At the dashed yield line, look to your LEFT and YIELD to drivers already within the roundabout. REMEMBER: in a multilane roundabout, you must yield to BOTH LANES of traffic.

Once a gap appears in the traffic, safely merge into the roundabout and proceed to your exit. Look for pedestrians upon exiting, and use your turn single to indicate your intention before you exit. If there is no traffic within the roundabout upon approach, you may enter without yielding.

What about emergency vehicles?

If you have not entered the roundabout:
Drivers should pull all the way to the side of the traffic lane and let the emergency vehicle pass, just as you normally would.

If you are within the roundabout and an emergency vehicle approaches:
Drivers should exit the roundabout FIRST before pulling over to allow the emergency vehicle to pass.
