Tomorrow (31st), the last day of 2022, the New Year's Eve bell-ringing event will be held at Bosingak in Seoul for the first time in three years.

As close to 100,000 people are expected to gather, we must pay attention to safety above all else, and a new method has been introduced for this.

Reporter Park Ha-jung went to the site where the event was being prepared.

Due to COVID-19, I couldn't see him for a while.

Tomorrow, here at Bosingak, a New Year's Eve bell-ringing event will be held starting at 10:50 p.m.

Preparations are in full swing, such as clearing the frozen snow from the floor and setting up the stage.

As the first event in three years was expected to attract a large number of people, the city of Seoul decided to apply a new crowd management technique on a pilot basis.

First, 5 CCTVs were temporarily installed.

It is a place where you can see areas expected to be densely populated, such as the pillar right in front of Bosingak and the entrance to the alley from the main street.

Artificial intelligence AI counts the number of people per unit area contained in this real-time video, and

Graph whether or not the risk criterion has been reached.

[Yun Cheol-won/Technical Director, AI Image Recognition Specialist: In fact, when the limit (risk standard) is exceeded, an alarm comes and the person in charge can be contacted via SNS or e-mail...


The risk standard presented by the Ministry of Public Administration and Security last month was 6 people per 1㎡.

The Seoul Metropolitan Government plans to manage crowds by notifying related organizations such as police and firefighting and sending on-site announcements and disaster text messages when more than 7 people per square meter are concentrated.

When the reporters analyzed the video of the Bosingak bell ringing event at the end of 2019 together with another AI video analysis company, some areas went back and forth between 'border' and 'danger'.

Tomorrow, at the intersection of Jonggak Station, ringing-type relay electronic display boards will be installed in all directions to prevent crowds from crowding in one direction. About 1,000 agents are also deployed.
