NAMYANGJU — Namyangju, a city in Gyeonggi Province, ran real-time monitoring based on big data during the Chuseok holiday, upgrading its response systems for disaster safety and road traffic. Going beyond on-site response, the city analyzed accumulated data in detail to identify risk factors and shifts in local activity before and after the holiday.
The city said on the 30th that it had monitored disaster safety and road conditions in real time from the 24th to the 27th and analyzed the accumulated data from multiple angles.
In disaster safety, emergency medical calls were concentrated early in the holiday as travel surged, according to the analysis. Ambulance dispatches, which averaged about 80 a day before the holiday from the 15th to the 23rd, climbed into the 90s on the 24th and 25th at the start of the break before gradually stabilizing. Rescue cases showed slight daily fluctuations, while fires remained at low levels throughout the holiday.
Road conditions also showed a stark contrast in line with changes in traffic volume. Construction-related incidents fell about 92% from before the holiday, while accidents rose about 32%.
In the later part of the break, as returning travelers and day-trippers crowded the roads, an indicator covering congestion and other road conditions jumped 98%, showing that traffic tie-ups were concentrated as travel increased. On the 28th, just after the holiday, figures for emergency calls and road conditions all trended lower, returning to normal levels.
"By making full use of the integrated data platform, we were able to see at a glance how conditions in the city changed over time," a Namyangju official said. "Going forward, we will keep expanding public access to administrative and safety data closely tied to residents' daily lives, so that citizens can grasp city government information and local changes a step ahead."
