( this should really be a in a different thread about BSIP and frequency, as its nothing to do with electric buses!)

You may not beleive it, but high frequency definitely DOES generate extra passengers. It's partly because if the service is not running perfectly (roadworks? unusual traffic congestion? a breakdown?) there is less likely to be a significant gap between buses. As with many other things in life, in general people are more influenced by their worst experiences than the normal service. (That is why the shocking level of missing buses that has occurred from various depots/ various operators in recent years has been so damaging). 

If services were able to run like clockwork, every 10mins would be enough to reach the sweet spot, so you are right to point to other things that could be done. 

I agree that, say, changing from hourly to every 30 mins has a bigger effect for passengers; but the fact that the service was only hourly hints that services like that have lower overall passenger numbers. Doubling the frequency basically doubles the costs, but you don't get double the passengers, so its not a case where the service is going to be viable at the higher frequency. (This isn't a point about commercially driven operators - the arithmetic is the same if/when the services are publicly owned.)
