Lenexa’s Traffic Division provides a safe and efficient travel system for vehicles and pedestrians navigating the city’s streets. The division consists of the traffic engineering staff and traffic signal technicians who work together to maintain approximately 6,000 street lights, 65 traffic signals and over 10,000 street signs. They inspect all traffic signals twice a year, relamp about 1,500 street lights a year and manufacture signs in-house using a specialized computer system.

In addition to regularly scheduled maintenance, the division responds to more than 300 street light and signal requests for service from citizens each year, and also assists with the setup and take down of most community sponsored events.

Innovations and technology

The Traffic Division’s mission is to provide safe and efficient traffic operations. The following are some examples of traffic technology and innovation utilized in Lenexa.

School zone flashers

Lenexa’s school zone flashers are controlled by a system that enables the traffic division to turn them on or off on a moment’s notice. This is a benefit for the safety of the students, as well as an advantage for the traffic division. For example, if school is let out early, we can turn on the school’s flasher to alert traffic to slow for students in the area. In the past, one or two workers were called out to manually adjust the flasher, if they were available. Now, for the most part, it’s as easy as flipping a switch.

LED traffic lights

LED is an acronym for light-emitting diode. Most of Lenexa’s traffic signal lights have been replaced with LED lights, instead of incandescent or fluorescent bulbs. One major advantage of using LED lights is that they use significantly less energy than bulbs and are easier for motorists to see, especially in direct sunlight. Replacement for these lights can be measured in years rather than months, which is a great time saver considering there are approximately 65 traffic signals to monitor throughout the city.

Intersection cameras

There are several cameras strategically placed at intersections throughout the city. These cameras allow for close monitoring of traffic flows. If there is a call about a backup or congestion, the intersection can be viewed via camera, rather than sending out a crew to assess the situation. Then, if an issue is identified, it can be corrected remotely.

Another benefit of the cameras is that the activity at an intersection can be videotaped and reviewed to see if adjustments or improvements could be made to the signal.

Traffic Adaptive Signal System

This is an innovative technology Lenexa is using on College Boulevard between Lackman and Greenwood to optimize traffic flow. The system enables the traffic signals to communicate and coordinate through video detection in real-time in order to best control traffic flow.

Illuminated and advance street name signs

Illuminated and advance street name signs placed along major corridors within the city allow drivers to see which street is ahead at a farther distance than a sign that is not illuminated, or placed at the corner of the street. This helps drivers keep their eyes on the road.
