BCEO UPGRADES TRAFFIC SIGNALS

Butler County Engineer Greg Wilkens reports that 29 traffic signals operated and maintained by his office are in the process of receiving upgrades. The signals are being refitted with new red and green LED lamps. As part of this re-lamping, 45 signal heads will be changed out with a red arrow per the new Federal requirement. The change is part of the 2009 Federal Highway Manual Uniform of Traffic Control Devices which requires “protected-only” left turn signals to have red arrows replace all circular red indicators. The purpose of the change is to enhance uniformity and eliminate “left turn signal” signs. Previously, as motorists approached a designated left turn lane, the signal transitioned from a green arrow to a yellow arrow, and then to a solid red circle. The new signal will transition from a green arrow to a yellow arrow and then to a red arrow. Drivers CANNOT turn on red arrows.

The 29 intersections that will receive new LED lamps will be replacing the first round of LED lamps installed in Butler County back in 2004. "The first re-lamp equates to eight years of use from the original the LED signal lamps," said BCEO Traffic Engineer Matt Loeffler. "Prior to installing the energy efficient LED lamps in traffic signal heads, an annual blanket replacement of incandescent light bulbs was required. Thus, Butler County has benefited from significant savings in labor hours as well as 90 percent less energy consumption."

The 543 new LED lamps were purchased using the ODOT Cooperative Purchasing Program at a total of $15,459. The ODOT Cooperative Purchasing Program permits political subdivisions to purchase specified items at the best unit price available. Total labor cost is estimated at just under $12,000.

The upgrade is expected to be complete by the end of July.
