Abstract

The Baltimore project started with a simple premise: there should be a safe and effective way to save energy and dollars by decreasing the brightness of traffic signal lights at night. The supervisor of Electronic Maintenance for the Department of Transit and Traffic conducted some preliminary tests of a dimming device developed by a local firm. These tests confirmed that energy savings of about 22 percent might be possible.
