Well, there's no way I'm going to read all 132 pages from 6 years right now, maybe I'll take it in instalments.
Here's the transit map Veloise alluded to. For the first three and a half years of living in Grand Rapids I lived in Belknap Lookout. I would often think a local train serving a stop on Lafayette at the corner of Bradford would be a great addition to the area, and then I saw that tied in with what the Area Specific Plan was trying to put together. So I set about looking on Google Maps aerial views and also went out looking at some stretches of rail, and put together a plan for a three-line "metro". It uses existing tracks or places where tracks could be relaid, and I recently adjusted it to take into consideration the new location of the Amtrak station.
The initial plan had lines from Coopersville to Ada, Sparta to Byron Township, and Hudsonville to Cascade Township. I then reduced it to stay within the boundaries of the six cities of the ITP.
My map is based on the style of Harry Beck, something I grew up with as a Londoner. I chose the Corbel font as a very "transit" looking font. My initial lines were red, blue and green; but I changed the green one to yellow to match the GR city colours.
I added the Silver Line to the map, and also some of the more important Rapid bus connections. I feel bad leaving my 6 off the map completely, but it doesn't cross the lines at all, except at Central Station where everything meets anyway.
FYI: I haven't worked a day in planning, cartography, local authorities or transit agencies in my life. This wasn't even done using vector graphics, so it's a little crude. But I think it gets the point across: That GR would benefit greatly from another form of mass transit to coexist with our already excellent and blossoming bus service.
