Let's hope it isn't so reduced in the study area! I figure the desire to promote transportation solutions is pretty closely tied to stakeholders and politicians, with the aim of benefiting one or the other, and the assumption on their part that the public will also benefit. Then you have that OTHER entity, which I prefer to think of as one group - the transit experts, who often exercise the strongest influence of all - largely because no one will dare to contradict them. The interests of planning professionals, especially with rail, do not always align with those of the public. But I'm not a transit professional - so with me you're safe!
In NYC we have 25mph speed limit, which succeeded in getting fatalities to zero city-wide, for a while. If big, planted median and sidewalk margins were added... and you could diplomatically get it down to two lanes, with heavily marked crosswalks mid-block (only for a short distance) with clarity on who has right-of-way - you could turn it into a more pedestrian-friendly area - which Corktown SHOULD BE - since it's historic, recreational, etc.
Hi Aaron: I have a partially designed 1.8mi subway line that might meet with your approval. There's not much unconventional about it though it might want to adopt a London Underground-type vertical squeezing to some extent: https://challenges.cityoftomorrow.com/challenge/detroit/explore/michigan-avenue-subway - The Grand Trunk 3-track elevated line in Detroit would do well to fill in with passenger service where this two-line spoke-and-hub subway doesn't go - probably for a higher fare - extending to Mt Clemons, Port Huron or... Toronto - since that route is way more advantageous in terms of population and could be made about the same length given revival of an old stretch in Canada. The Toronto approach is more populous too. Without something along the general route of this subway having reasonable speed and high capacity the prospect of reviving Michigan Central as a transit hub doesn't seem very likely - including another longer service I have in mind - Detroit-DWT-Downtown Toledo. (Terrible # of grade crossings on that one.)
