Im open to LRT in general as a means to upgrade local bus service, but in most situations it cannot be true RT since that entails speeds that are competitive with basically any other mode in a given context. So in my books that means the busier urban corridors with high ridership and alightings on a per-km basis, not merely ridership on the entire route.
This is my interpretation of the need you describe, which contradicts using LRT. In essence, the further out you are, the faster transit needs to be because there’s fewer destinations. As we plan it, LRT intends to increase such activity along it. But we’re building them to improve the pre-existing trip patterns! We know this, it’s why we extend our subways- but costs prohibit being more generous. Hence we have always been obsessed with “intermediate capacity” transit in Ontario. We might be figuring things out now though; 3 LRTs are on the horizon, and their performance will be looked at closely.
