GE has solved a problem that I read about each winter. Each year during winter I see at least one story about sticky snow covering LED traffic signals. GE devised an LED-based smart traffic signal that combats this issue.
Fluorescent bulb traffic signals do not last as long and use more electricity. However, the inefficiency of fluorescent bulb traffic signals did have one benefit. The heat from the bulbs prevented ice from forming on the lights in snow and ice storms.
The new GTx signal light uses sensors to monitor ambient conditions. In cold weather when there is a high likelihood of sticky snowfall, the sensors automatically activate a heating element to warm the outer shell and help stop ice and snow from forming on the shell so drivers and pedestrians can continue to see signals.
GE says that the new smart traffic signal GTx can minimize confusion caused by snow and ice covered traffic signals.
The GTx LED traffic signal lights can be used for new or retrofit installations. They come in red, yellow, and green meet rigorous certification and testing standards.
