I was thinking of all the issues that will come with this project. If they really plan to remove STO buses from Ottawa downtown entirely, it means that the STO will experience a city wide catastrophic failure every time the LRT will be down. Everyone coming from the Rapibus will be stuck at l'Université du Québec, unable to get downtown.
Considering that they plan to run the trams along the sidewalks rather than the median on the Chemin d'Aylmer due to the narrow right-of-way, we can expect the trams to get involved in car crashes frequently, since a LRV can't break as fast as a bus.
In Toronto,
streetcars were involved in 549 crashes in 2017, which is more than once a day. Looking at the C-Train in Calgary, disruptions from car crashes sometimes last 2 hours.
I would rather see BRT to Aylmer and Le Plateau than an unreliable LRT system that will paralyze the whole transit system regularly. It's like the cancelled 2006 plan in Ottawa, trying to use BRT for the busiest corridors, while using LRT for lower ridership corridors, when it should be the other way around. We're looking at the cheapest solution and it's going to cause a lot of issues.
I couldn't find anything more recent, but that's a 2031 transit ridership forecast made for the 2008 transportation master plan. We can see that the Rapibus is where most of the ridership is. It wouldn't be politically popular to convert a brand new BRT system to LRT, but I think that we need to seriously start to talk about converting the Rapibus to a fully segregated LRT similar to the Confederation Line.
