Let's start with a brief look at the nation's roads
The volume of traffic will likely peak today, the day of Chuseok, as families go to and from their hometowns.
The Korea Expressway Corporation says more than five.eight million cars are expected to be on the move on north and southbound lanes, marking the highest daily volume of traffic in Korean history.
As of five pm, Korea time, a trip to the southern city of Busan from Seoul will take about seven hours hours and six-and-a-half hours, going the other way; under normal circumstances the drive would take less than four-and-a-half hours.
The heavy congestion is expected to continue through Thursday morning.
