I am curious.

Ohio doesn't seem to have a centralized placed to look up that information, unlike other states such as Michigan or Wisconsin. It appears to be information a regional planning department may have - I see references for the Columbus and Cincinnati metro areas posting that info.

The term you're looking for is Annual Average Daily Traffic (AADT). Typically a 2-lane highway like US-68 should have no more than 8,000 to 10,000 vehicles per day traveling on it for acceptable "Level of Service" - no significant congestion or an abnormal number of accidents.

North of US 33, US 68's AADT hover at around the 5k mark, so that's around 3.5 vehicles per minute.

Sure they do.  https://odot.public.ms2soft.com/tcds/tsearch.asp?loc=Odot&mod=  .  Depending on where you're saying in northern Ohio, it has an AADT of 7382 in between Findlay and Arlington, making it 7382/(24*60) = 5.12639 cars per minute or one car every 11.7 seconds.

Clearly my Google-fu was failing me. Thank you.

Keep in mind that's an average for the entire day - one can safely assume about 70-80% of that traffic is happening during daytime hours. So figure it's closer to one vehicle every 4-5 seconds during the day, with very light traffic (say, one every 30 seconds) between 11pm and 5am.

Absolutely.  It's tough to find them for some states.  My AADT thread was a bear for some of them for sure (looking at you, New Mexico).

Sure.  I just tried to exclude as many variables as possible to come up with the simple answer.  I'm sure it's a nice Bayesian distribution.

General guidelines are that the peak hours are about 10% off AADT in the peak hours and 20% in the urban areas. Of course, every road has its on characteristics and variations, but for very rough estimates that's a good start.

Didn't help that ODOT changed their website design, several years back, from being a data center, to now just press releases and traffic flow maps.
