Traffic Calming Program

The city has developed a traffic calming policy to help deal with complaints about traffic, particularly speeding, on residential and collector streets.

Traffic calming measures may include signage, speed bumps, stop signs, increased police enforcement or roundabouts - anything that will reduce the negative effects of motor vehicles, alter driver behavior and improve conditions for residents.

Although funding has not been earmarked specifically for the city's traffic calming program, individuals may contact the city and request inclusion in the program.

City staff will use the traffic calming toolbox to determine what, if anything, would be beneficial for the neighborhood.

Roundabouts

Roundabouts are circular intersections used throughout the world, and more recently, Kansas City and Overland Park.

Roundabouts serve vehicles from every approach simultaneously unlike traffic signals, which can cause delays. The center islands of a roundabout deflect entering traffic and reinforce driving speeds lower than 25 mph.

Overland Park's roundabouts include:

  • Santa Fe and Conser (two-lane);
  • 110th and Lamar (two-lane);
  • 113th and 115th and Switzer;
  • 133rd and Lamar (two-lane); and
  • Smaller, one-lane versions throughout city.

Roundabouts are one of the safest types of intersections. They reduce injury accidents, delay traffic, and reduce fuel consumption, air pollution and construction costs.

Flashing Yellow Arrows

Flashing yellow arrow traffic signals replaces the green circle indicator and offers a safer, more efficient way for a motorist to make a left turn.

The left arrow provides a more direct message to the driver and reduces confusion since the left-turn display is no longer the same symbol as the adjacent through lanes. It also prevents a driver turning left on a green circle from inadvertently implying that the left turn has the right-of-way over the opposing traffic.

What do the arrows mean?

Solid Green Arrow

A steady green arrow indicates that drivers making a left turn have the right-of-way.

Oncoming traffic has a red light.

Flashing Yellow Arrow

A flashing yellow arrow indicates that drivers may proceed to turn left after yielding to oncoming traffic and pedestrians.

Oncoming traffic has a green light, so drivers must wait for a safe gap in traffic before turning left.

Solid Yellow Arrow

A solid yellow arrow indicates that the left-turn signal is about to turn red. Drivers should prepare to stop or complete the left turn if they are within the intersection and there is no conflicting traffic. Drivers should treat the solid yellow arrow just like a standard yellow ball indication.

Solid Red Arrow

 

A solid red arrow indicates that drivers must stop and may not enter the intersection.
