So the guideways are narrower than roads since they only have to be marginally wider than the bus. Which in turn gives you space to add a walking/ cycle path alongside. The guideway setup also allows for level boarding. The buses in the guideway go right up to the edge of the bus stop.
This isn't necessarily a whole new form of transit that requires all new buses. I'm sure it wouldn't require much to install the guide wheels on the existing fleet of buses.
It's something than can be used by Brampton transit to enhance their bus service across the city. Similar to a bus lane or the slip lanes used by ZUM at the intersections.
EDIT: The whole reason I'm proposing this idea, which I know sound kind of bogus at first if you've never seen it before, is because there is already a plan in place to convert the old rai line into a walking trail. This seems like the best solution to still offer a walking/ cycle trail while still providing rapid transit. I believe there are some stretches along the OBRY that wouldn't be wide enough to accommodate two bus lanes and a walking/ cycle path. But you could probably fit in two guideways and a walking/ cycle path.
EDIT: My emphasis on the U.K. style of guided busway is because it's use of concrete guideways seem to best integrate into the surrounding environment. Natural drainage into the grounds etc.. Where as other guided busways in other countries use metal tracks and often don't have walking trails beside them.
