BRT makes no sense without the frequency. YRT has a huge problem with running buses at frequencies that encourage using transit. The other nonsensical thing YRT does is completely ignore running frequent connections to GO Train stations during peak hours. Talk about ignoring low-hanging fruit!
I don't disagree but as I've said before, viewing Viva solely through a short-term ridership/frequency lens is missing the point. It's a city-building effort which is facilitating a fundamental change in the built form of the corridors along which it's built. YR has put itself in a bit of a Catch-22 by cutting local service etc. but it's not a 5-year project. Let's see how Yonge and Highway 7 look in 10 years (they already look very different from 2003) and then look at ridership numbers.
