The experiment is now running. Oxford's state schools, used mainly by the city's residents, aren't broken up. Oxford's private schools, which can have gigantic catchment areas, are starting to go on half term.
So let's see what happens over this week, especially from Wednesday.
Next week, we get to re-run / validate our previous experiment, which examined the effects of private (not state) schools on Oxford's weekday traffic hotspots of Banbury / Woodstock Road and Iffley Road.
Private schools tend to break up a few days earlier than state schools.
