Yongsan-gu Creates Safe Return Paths Using Big Data Platform

Attachment of Sensor-Type LED Building Number Plate

Nation's First Implementation of Data-Driven Scientific Administration Using Big Data Platform

23 Safety-Vulnerable Areas... Eco-Friendly LED Sensor-Type Building Number Plates Installed

Location Sent to 119, 112 in Emergencies... QR Code Included

Yongsan-gu is introducing a safe return path by attaching sensor-type LED building number plates to safety-vulnerable areas for the first time nationwide. This realizes data-driven scientific administration utilizing a big data platform.

The sensor-type LED building number plates charge solar power during the day and automatically emit light when pedestrians approach after sunset.

The district conducted on-site surveys to check sunlight exposure and the aging status of the number plates at project sites.

The building number plates are equipped with QR codes that send location information to 119 and 112 to assist rapid reporting in emergencies, allowing residents to walk safely through dark alleys.

A district official explained, "The Yongsan-style safe return path has the advantage of easily securing nighttime pedestrian safety at low cost."

Safety-vulnerable areas were identified by cross-analyzing the district's big data platform and 360° VR Safe Road View data. Vulnerable locations were confirmed through spatial information site analysis including floating population, CCTV installation status, crime rates, single-person household ratios, streetlight brightness, and dead-end alleys, totaling 100 sites.

The district invested 3.91 million KRW to install sensor-type LED building number plates at 23 locations in narrow alleys and areas densely populated with old houses, including Dongbinggo-dong (2 sites), Bogwang-dong (17 sites), Seobinggo-dong (1 site), and Itaewon-dong (3 sites).

Kim Seonsu, Acting Mayor of Yongsan-gu, stated, "Based on the project results, we will expand the safe return path target areas and do our best to discover administrative services that residents can feel through data analysis."

Last year, the district invested 730 million KRW of local funds to build a big data platform that collects, links, stores, and analyzes customized local data scattered across sectors and institutions, and conducted staff training to promote data-driven scientific administration.

The 360° VR Safe Road View is a Yongsan-gu system that provides on-site information about areas inconvenient for passage such as no vehicle access, dead-end roads, and stairs. It was launched last year as the nation's first service to eliminate blind spots in road views.
