Or even closer to home, the Green line in Boston (not to mention the BRT new silver line), which is essentially street cars running underground downtown then on surface ROWs in more residential areas..
We should definitely be adding these (and the new LRT) lines to our maps, that should appear in both subways/lrt cars & stations/stops.
As a tourist, I find it very assuring and useful when trams/lrts are integrated into the subway map... Most don't care that its a different mode, so long as they can map out their route.
Buses, don't easily translate into this category because often they can have multiple routes/destinations on the same stretch before splitting off into some other tangent. Which makes it 1) too hard to represent on a subway map 2)too daunting for users to want to take it... buses are for locals familiar with the territory.
knowing the LRT is a fixed route, makes it something that can be represented (although in its own specific way identifying it as an LRT) alongside our subways.
