Phase 3 of consultation on the Haney-Langley BRT and King George BRT are released. Looks promising with dedicated BRT lanes being laid out for (according to Kenneth) 90%
for each route

Pointers: New Flyer has produced a number of 5-door buses over the last few years; the closest example to us is Rapidride G Line in Seattle.

If anything, a valid concern is the width of the center platforms, which is the main section for both of these lines. I think some of these stops are going to default to a 120ft long platform that is barely 10 ft wide. I have yet to review the actual survey. Using 5-door buses hampers fleet flexibility IMO - Seattle needs 13 buses (including spares) to operate the 3.5km G-line at every 6 minutes.
Another idea I have would be to use standard 3-door articulated buses but have them swap sides at each stop. E.g. northbound buses load to the left of the corridor and vice versa. I think this would require a speed restriction or a dedicated signalling system.
