Suwon to Replace All Traffic Signals with LED Lights by 2013

Suwon City plans to replace all traffic signals with LED signals by 2013.

According to the city, from 2002 to last year, it invested approximately 3 billion won to replace approximately 40% (about 2,560 units) of all traffic signals with LED signals.

This year, the city plans to invest 300 million won to replace 377 LED traffic signals at 41 intersections on Seongsungno, Changnyongmun-gil, Indoenae-gil, Segye-ro, and Maesan-ro. Construction began in early June and is scheduled to be completed by the end of July.

A city official stated, "Going forward, we plan to secure 1 billion won annually to replace all traffic signals in the region with LED signals."

Meanwhile, LED traffic signals have higher clarity compared to conventional incandescent traffic signals, making it easier for drivers to identify signals, and there is no phantom effect during rush hours (unclear signal blinking state due to backlighting from sunlight), which is effective in preventing traffic accidents.

Additionally, compared to the 100W power consumption of existing signals, LED signals use approximately 7-15W of power, achieving energy savings of over 90%. Moreover, compared to the lifespan of about 6 months for incandescent bulbs, LED signals are semi-permanent products, resulting in fewer traffic signal failures and reduced maintenance costs.
