I recently read the Route Ahead summary from 2024 and CT wants to do a lot but has not been able to get funding for everything council and the City has wanted to do. They're hundreds of millions of dollars behind in required funding for the Primary Transit Network. At one point CT was honest that they didn't have the trained drivers to make a PTN happen, because of layoffs during Covid, I don't think that is the problem anymore. Everyone knows what needs to be done but the money isn't there. I feel bad for CT, you have these issues that throwing money at would actually solve, unlike some things where money isn't the issue, but you're not getting the funding.
Conceptually, the most expensive part of Calgary Transit's operation is lack of priority over cars in all the ways from major capital projects to operations to day-to-day, particularly where they need it the most (like downtown and entering/exiting major destinations like hospitals).
The caveat for Transit project's that sink their cost-effectiveness is always hidden in the concept of
priority. In practice, what Transit projects most often do is aim for Transit "priority" with the following fine print:
prioritize transit ... as long as it doesn't meaningfully impact vehicle trips on the same corridor.
For example, reasonably effective transit-only lanes on major avenues only requires some new paint, a few signs and a few signal tweaks - probably a few million bucks and some traffic enforcement changes, it's money but hardly the tens or hundreds of millions like a single interchange, or billions for a new LRT line. The bus-only lanes would be a huge travel time improvement for dozens of routes and reliability improvements not achievable under any other possible project. Transit would also meaningfully close some travel time gaps for some trips, encouraging further revenue as mode shift occurs. Almost any bus route could run 25%-50% faster in rush-hour downtown without spending an additional dollar on a new bus or hiring a new driver if we took an existing congested lane and gave over exclusively to transit.
In practice, instead of a simple implementation of bus lanes happening that improves bus travel times at the expense of regular traffic, what will happen is that transit priority caveat kicks in and things immediately get watered down. A traffic engineer model will flag that the delays to regular traffic would become "unacceptable" to an arbitrary target they have. To fix this, the transit project would need to bloat - require additional infrastructure capacity and modelling to reduce the possible impact to regular traffic flows. All this becomes in scope of the project, ballooning the costs, watering down the benefits and creating all sorts of political risks that are likely to kill the project before it even gets off the ground.
In the most extreme examples, a transit project counter-intuitively makes transit competitiveness worse - transit's limited dollars are actually helping it's competitors more than itself. Most projects that add bus bays do this as the only travel time improvement is gained by the driver in the car no longer stuck behind a stopped bus, while the bus is now slower due to having to wait to merge back into traffic.
All that pro-transit rhetoric aside - we can still be pragmatic; not everywhere needs absolute transit priority. But if we are serious about transit cost effectiveness and cheap ways to improve a cash-strapped service, the pavement is already there. We just have to take it away from cars and give it over to busses. Yes this might mean more congestion for regular vehicle traffic - but with the benefit of cheap, faster and far more competitive transit for a low budget cost. That's the trade-off. That's literally what
priority for transit actually means!
