I asked the question,
in the OC Transpo thread, about what people would propose as changes to Ottawa’s transit system, if they were asked to do so by a new Mayor. Since I am adding to my response, I am moving to this thread, so as not to drag the other off topic.
In general, I would like to see a plan to run higher-order transit along main lines to connect general areas of the city. These could be BRT, trams/LRT in dedicated lanes, or subways. This would allow people to quickly get to any general area; then they would take a local bus or walk.
In the above diagram, the red line is already under construction – except I have also added some, but not all, of Stage 3. I’m not convinced that the western-most extension through Stittsville is warranted.
The dark blue line is the Baseline BRT concept – except, I have changed the western end to be a bi-directional loop. Alternate buses will go the opposite direction around the loop. The same alternating-direction-around-the-loop idea is used on the fuchsia line in the east end. (And, potentially, the green line in Barrhaven. See that option, below.)
For that fuchsia line, I have assumed a new bridge across the Rideau River, connecting Montreal Road to Daly Ave. This is still close to the main street (Rideau), but makes a connection to Sussex easier.
The light blue line is what I am calling the Carleton Line. Despite lrt’s friend’s suggestion to connect the Bank Street Subway (the yellow line) to the airport, I resisted. Yes, it would be nice to have a direct (no-transfer) connection between the airport and downtown, but I feel that the majority of people taking transit to/from the airport may not be headed downtown. The light blue line is also a lower capacity line, likely having smaller vehicles, that might be better suited for the volume of passengers that I expect on the line to the airport. And smaller vehicles would fit better with what is currently being built.
The yellow line (the Bank Street Subway) will be a high-capacity line. As such, I am debating whether I should extend it across the Rideau River into Barrhaven – probably continuing along Chapman Mills to Marketplace Station. This would allow the green line (which would be lower capacity) to have a bi-directional loop around Barrhaven. Extension of the yellow line into Barrhaven would not mean that the red line to Barrhaven could be removed. Both lines would likely be needed to handle the future population of Barrhaven.
Those with a keen eye would have noticed that I have added dashed-line extensions across the Ottawa River, into Gatineau. This would extend the light blue, yellow, and fuchsia lines.
This mainline topology would be the basis of the future transit system. Areas between these lines would be serviced by local buses and a few regional buses.
