In the news today that downtown rates are going up $35 - $40. Apparently due to increased downtown development combined with the number of construction workers creating the same. I guess construction workers will get replaced by office workers, venue attendees and residents so it's not really like an opportunistic peaking demand issue.
Maybe this is another expense that could be "app shared'. You buy a daily pass and then sell remaining time to someone coming into the lot. Or you buy two hours and only use one, click an app and someone nearby gets notified of the 1 hr ticket.
Then there's all the underutilized building parking with assigned stalls. Maybe the mayor and city council should be sharing their stalls through some app. All in the name of efficiency and cost reduction.
I imagine there must already apps in existence to find available parking lots and stalls in buildings that are owned by residents, etc. according to certain characteristics like available space, fee/rate, location, heated or not, safety rating, patrolled, etc.
