Unfortunately, the bulk of suburban neighbourhoods (1970s and later) are constructed with a circulator road that passes within 400m of all of the houses and very few alternates.
Consider an inner city area: looking at Tuxedo Park, there are buses on 4th St NW (2), Centre(3/301), and Edmonton Tr NE (4/5). These streets are roughly 600m apart, so most people have average 150m walk distance east-west. Viewed in isolation, you could in principle:
- Drop the Centre St bus and have everybody walk to Edmonton or 4th, with an average walk distance of 300m.
- Drop Edmonton/4th and only run Centre (average walk distance of probably 400-500m).
- Run 2nd E and 2nd W (average walk distance around 250 m).
In practice, of course, all three of these are fairly busy bus corridors, in particular Centre St.
But look north to Harvest Hills, where the 88 does a loop through the community. It goes from 78th Ave north up Centre, then does a loop on Harvest Hills Drive, passing within 400m or less of all of the houses (average walk distance of 200m), I count it as a 8.6 km loop or so:
The only feasible density reductions I can think of are cutting a couple of corners, which drops the loop down to 8.1 km, which increases some people's walk distance, but more importantly isn't much of a reduction at all in terms of service; you're pissing off 15% of the community, and saving pennies.
The only other option with this bus is just run the corner of the neighbourhood; this is a more substantial reduction, down to a 6.3 km loop, but half the neighbourhood has really long walks, up to 1200m and there isn't really much of a point in running the bus at all:
Or you could remove the bus entirely and make everybody walk to Centre St, but the average walk distance would probably be over 1 km.
The only other way to reduce density would be to reduce frequency, but the 88 only runs every half hour as it is right now, and the run takes... half an hour. So you can't even really reduce frequency (without merging the route with another) - even if we were to accept hourly buses as something worth doing.
The Alanis Morrisette irony is that the parts of the city with a grid network are both generally the only places you could reasonably reduce bus route density and also the places that have the most transit-supportive land uses and potential for intensification.
