◆Overview of traffic congestion prediction
- This year's weekday arrangement will be a "scattered holiday in the first half + four-day holiday in the second half" pattern, so we expect there will be a lot of traffic congestion in both directions during the second half of the four-day holiday.
- Because the first half of this year includes weekdays, leisure demand is expected to be lower than last year's three-day weekend, and traffic jams longer than 30km are expected to decrease on many routes. However, on routes such as the Tomei Expressway, which has a lot of business traffic, traffic jams longer than 10km are expected to increase, especially in In-bound direction.
