Thanks for the great article. As an operations researcher, definitely food for thought. My one concern with these sorts of forward-thinking urban optimization projects are the policy barriers. With this application in particular, what do you see as the primary bureaucratic challenges? Suppose you could demonstrate a significant improvement (e.g. in occupancy, or avg. time to locate parking, or even just reduced complaints)…are there zoning restrictions, other vested interests that would prevent / delay adoption of shared use?
