<Anchor> When



there is an accident on the road or when there is a lot of traffic, the police adjust the interval at which the traffic lights change. Since no one can touch the signal-changing equipment like that, I put a lock outside, and the key is being sold on the Internet.



Reporter Han So-hee reported exclusively.

Signal controller keys were unified nationwide so that traffic police could quickly respond to emergency situations.



When security issues such as the possibility of duplication emerged, the Seoul Metropolitan Government began replacing the key with another key in 2015.



However, six years later, 60% of the 4,400 city controllers in Seoul, or 2,700, still use the old key.



However, the same key as this key is being sold at online shopping malls.



Even the name says it is a signal key, and anyone can buy it for 13,000 won including the lock.



[Seller: The factory itself named it signal key and came out. It's correct to go into the signal control box.] The



signal key I ordered online has arrived. 



I'll tear it apart and check it out.



Also contains the same key that says Traffic Sign.



I opened the signal controllers in downtown Seoul with the key I bought.



All unlock easily.




Not only the controller, but also the unmanned equipment box for traffic enforcement and the traffic management system box are opened.



In particular, the transportation management system contains expensive equipment such as a CCTV control device.



The Seoul Metropolitan Government, which is responsible for management, is unaware of this fact.



[Seoul City Official: (It was also sold on the Internet, but did you know about this? The city?) No, I did not know before.]



In 2013, a man in his 40s broke the signal controllers at 16 intersections, paralyzing traffic in the area. .



[Lee Seung-mi/Seoul City Councilor: If someone uses it maliciously, a major accident may occur…

It is a situation where we need



to pay

more attention to physical supplementation.] The

city ​​of Seoul announced that it would investigate the circumstances of how the key for signal flags were distributed together with the police and come up with countermeasures.
