I think the right conditions have to exist for pedestrianization (don't ask me what they are -- I have an intuition about them but can't really articulate them). Lincoln Square for instance would a great candidate for pedestrianization -- lots of nice little shops in a high density location. As for the Pedway, one of problems is like most underground walkways, navigation is difficult. There's no official map that tells you what destinations you can reach and how to reach them. You can't navigate with Google Maps, and signage is poor to non-existent. Also, most areas of the Pedway are quiet, secluded and feel unsafe. My sense is that the Pedway was designed for hyperlocalized usage (moving from one building to the next) and not as a network of passages.
