It looks like this is modelled on Jakarta's TransJakarta (Tije), a pioneering busway service that aims to provide metro-like reliability, frequency and capacity using buses running on fully dedicated lanes: https://en.m.wikipedia.org/wiki/TransJakarta
One of the keys to doing this is that, unlike ordinary buses and bemos which can and do stop anywhere, Tije buses only stop at designated shelters (stations, really). Not only are these elevated, but they're usually in the road median, connected by pedestrian bridges (so people don't dash across the road and get flattened), and start the fare area so passengers are already ticketed and ready to go when the bus arrives.
