The staff and running costs should be similar - just more spread out. It should theoretically maintain the same profit margin also, as those travelling from A to B throughout the day will do so whether their bus is every 10 mins or every 15 mins. That's an alternative to propping up an early morning/late night/Sunday service. Simply abandoning customers who don't travel throughout the day is not. Maybe this is something a VPA would achieve though?
You ask any bus company employee, whether they are directly involved with service amendments or not and they will tell you that reducing frequencies DOES reduce passenger numbers and revenue. Even something as seemingly small as 6 to 4 per hour.
Why do you think bus operators on services without direct competition maintain these levels of frequency on some of their important routes? Because they know that it is warranted. If your theory was right, surely they would reduce and save the cost assuming they will retain all passengers. But, they know that isnt the case, they will loose out.
So doing what you suggest will hurt any service financially and any VPA would be silly to operate as such. Why move a third of the cost into times of the day when there is very little revenue? Doesnt even sound sensible.
