quantitative
Piloted with 26 poles across six central sites in February 2021, the network grew citywide to roughly 1,000 poles by late 2025

quantitative
reported monthly accidents falling from 115.8 to 99.5, roughly 14%, with the largest fall in school zones, and visibility metrics up about 14% on an OpenCV analysis
clm-7b419936f185f2ee
quantitative
Integrating fixtures onto one pole cut average installation cost by about 23%
clm-3e0602512bcd694d
quantitative
An earlier Seongdong-gu pilot comparison found a 12-21% cost reduction
clm-a89abe25a59302c3
quantitative
The 14% fall in monthly accidents comes from a before-and-after comparison with no control group, over seven months, at sites chosen because they are school zones and accident blackspots
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
Awaiting operator and domain-expert review; publication of this revision implies neither.
Erratum on this revision's envelope. The snapshot, its hash and its permanent link are untouched.

src-f1944042ad2c327cTransportation Daily, 26 December 2025, on the analysis Seoul announced the day before. Seoul and the Seoul AI Foundation compared before-and-after data for roughly a thousand poles installed since 2020, over April to October 2025: monthly accidents fell from 115.8 to 99.5, about 14%, with the largest fall in school zones; an OpenCV analysis found visibility metrics up about 14%; and integrating fixtures cut average installation cost by 23% — the city gives about 50 million won per smart pole against about 65 million for separate poles, 'a difference of more than 10 million won'. 1,027 poles were in operation, in 17 types, the most common being the CCTV-plus-security-light unit at 259 (25.9%).
