Then an interurban bus network can be formed around it.This sort of thing is done already. That's how those matrix signs inform you that it's going to take you 25 minutes to cover 10 minutes worth of A1.
At the moment, nobody actually knows where people are travelling to and from, not even agencies like National Highways. Counts of drivers are done as they drive past so can only give a good idea of traffic in that particular spot.
I don't think it's widespread in cities, yet, though. It's different people responsible for those roads.
