Field notes
The prefecture table gives observed and estimated section counts separately, alongside observed daytime-traffic medians and maxima and the median heavy-vehicle share. Its hourly profile uses 6,241 sections with 24-hour observations; the page reports that 7 a.m. has the largest share, at 7.2%, while 3 a.m. has the highest heavy-vehicle share, at 66.3%. The cited source is the Ministry of Land, Infrastructure, Transport and Tourism's FY2021 road traffic survey.
