It's a great map, but most people here aren't demanding that and that's because they have no idea how much it would transform this city. There would, of course, be a lot more development on High, but we would also see it on streets like Parsons and W Broad. You would think the major decline of virtually every urban neighborhood in Columbus immediately after the streetcar removal/highway construction should be obvious enough, especially since that happened in cities nationwide. Most people don't put 2+2 together for some reason and don't see that putting back a similar system in place would breathe life back into all of our major urban streets.
Until there's better understanding of the implications of what a system like this would do, maps like these will just be pipedreams and we've just got to be more creative and persistent when it comes to prioritizing alternatives to cars and attracting businesses in our urban business districts. It also doesn't help that we let ODOT run ripshod over us.
