Toronto's new Official Plan is very much weighted towards public transit, walking, cycling, etc. - but it's more at the high-level policy end and less at the nuts-and-bolts level that I think Planderella is looking for. Toronto is leaving those types of policies for the Secondary Plans and Corridor studies that will spring from the new plan.
About 7 years ago, the Ontario Ministry of Transportation put out it's landmark "Transit-Supportive Land Use Planning Design Guidelines" - the Blue book. Not sure if you'd have much luck finding it down in LA, but if you can dig it up it's worth it.
I'm sure if you surfed the APA or TRB websites you could find some good references. Try the Cyburbia links section!
