I'd argue that it's comnute time to the core (or more broadly outside Scarborough), and by extension economic access, since the bulk of jobs are in the core.
Yes, most trips are in Scarborough. But those aren't there ones that really take long. Very few people are spending 1 hr commuting inside Scarborough. And the LRT wouldn't have done much for most of these trips anyway.
Guys like
@Forgotten slam me for supporting Smart Track. But from where I stand, I can see some palpable frustration with those commute times. And I can see that the subway has come to represent progress, investment, and economic access. This is why I sincerely hoped that we could have suburban rail and kill the mythology behind subways.
LRT can succeed in Scarborough. Needs a whole different sales pitch and implementation. And we really, really need to start pushing suburban rail (RER or Smart Track) for core bound commuters. Pitch LRT as the luxury streetcar to your 25 minute RER ride.
