Korea's expressways take 640,000 more vehicles a day over a four-day Chuseok

The projection adds 640,000 vehicles to an average holiday day, the difference between 6.05 million and the 5.41 million counted during last year's Chuseok ^[3][13]. The police answer to that increase is deployment, not capacity: officers concentrated on the routes to and from hometowns, with traffic management at chronically congested spots including traditional markets, bus terminals and cemetery parks ^[5][6]. Four days at 6.05 million is 24.2 million vehicle-days, if the projection window is the break itself; the plan describes the period only as the Chuseok holiday ^[15].

The enforcement calendar is the part a dispatcher can schedule against. It opens on the 17th and closes on the 27th, 11 days of policing for a break of four, and the crackdown on drunk and reckless driving sits inside the whole of it ^[1][14][4]. In my view planning should run to the 27th rather than to the last day of the holiday.

For anyone keeping a store open, the sites named in the plan are facilities that draw large crowds, including multiplex shopping malls, and everyday neighborhood businesses including convenience stores ^[7]. Volunteer neighborhood patrol groups will be used where necessary for escort-home services and joint patrols ^[8]. Robbery, theft, illegal private lending and voice phishing all get stepped-up prevention and enforcement ^[16].

This is a policing document, and it does not address freight volumes, courier staffing or retail rosters, so the 11.8% is the figure a shipper has to work from ^[17][3]. The Korean National Police Agency said the plan follows from expectations that demand for policing will be compressed into a short window, because the four-day break concentrates travel to and from hometowns and family gatherings ^[2].

"So that the public can spend a peaceful holiday, we will look more closely at people's immediate surroundings and carry out policing that people can feel close to their daily lives, from crime prevention to safety on the roads to and from hometowns," the police agency said ^[11]. For the duration, it will raise the rank of its situation manager from senior superintendent to senior superintendent general, and manage national conditions through the 112 comprehensive emergency response center ^[9][12].

Two readings of the same document pull against each other. The plan forecasts 11.8% more vehicles a day, and it also directs preventive patrols to neighborhoods dense with single-person households, on the stated basis that a growing number of people now spend the holiday alone instead of traveling ^[3][10]. If that group is larger than Korea Expressway Corporation assumed, the count lands under 6.05 million and the extra 640,000 never reaches the road ^[13]. A third possibility is that the daily average holds while the peak is worse than 11.8%, because a four-day break gives departures fewer days to spread across ^[2].

What would show the compression thesis wrong is a post-holiday count at or below 5.41 million a day, or a plan that winds down before the 27th ^[3][1].
