Abstract:

With the slowing of the American economy since 2008, it has become imperative that municipalities

identify areas in which costs can be reduced while still providing needed services to its constituents. The

use of traffic signals equipped with light emitting diodes (LED) provides opportunities for urban

municipalities to conserve both tax dollars and energy. With other advantages, such as the reduced

maintenance, a longer life span, and more illumination than the standard incandescent light bulb, LED’s

have become a viable option in cities around the globe as a first step in reducing municipal costs.

Furthermore, LED traffic signals could be retrofitted to solar energy in the future thereby enhancing the

move towards “green” technologies. The City of Houston is the focus of this case study evaluating the use

of LED traffic signals at selected intersections in and near the urban core.
