Light-Emitting Diode Traffic Signal Replacement Program

led lampsStrategy
Implement a regional plan to convert existing traffic signals to light-emitting diode (LED) lamps and develop a regional policy to install LED in future traffic signals.

Implementation Area
Municipalities with more than 50,000 persons, as determined by Year 2000 Census data, and Texas Department of Transportation (TxDOT) traffic signal projects in the North Central Texas Ozone Nonattainment Area

Foundation For Support
Recent local government conversions

The replacement of traditional incandescent bulbs in traffic signals with LED lamps provides an energy savings opportunity to local governments that translates into a reduction of ozone precursor pollutants emitted from electric power generator plants within the region. Local governments have confirmed positive experiences with conversions to this cost-effective alternative. LED technology has proven to be more reliable because of its increased life expectancy and reduced maintenance needs.

A goal-oriented regional plan to convert traffic signals to LED will be implemented in the nonattainment area. Where possible, the Regional Transportation Council (RTC) will identify and facilitate potential partnership opportunities with private sector energy companies that offer rebates for retrofitting traffic signals with LED technology. A subcommittee of the Surface Transportation Technical Committee (STTC) was established in Spring 2004 to develop a clearinghouse of information to describe benefits of available LED technologies and guidelines for implementation of these technologies. The conversion plan shall also consider the impacts of implementation goals on municipalities which do not purchase electricity from large private generators and are not eligible for rebates. The RTC will fund the program up to $400,000 for staff time and inventory development.

The RTC may develop project selection incentives to ensure timely implementation of this program.
