I am looking for a dataset of car-parking in any city. I am doing a research about car-parking / traffic and their impact in the life of US cities.
Is there any public dataset that you recommend ?
If you're not looking for real time data, you might want to search on the term 'parking study', which tends to look at the availability of parking in various areas.
I would assume that cities that have gone to dynamic pricing aka 'active parking management' would need to be collecting the data to set their pricing ... so Seattle and San Francisco would be prime candidates ... unless you're looking for more typical parking data.
I've seen datasets on car parking locations in a number of city open data portals. I did a quick Google (city car parking dataset) to find a few to get you started:
Displays the number of current car parking spaces available at each of the UPark car parks located in the city. Further information re UPark locations, operating hours, rates...
The location of car parks. This dataset includes information about facilities available at each car park and information about fees, opening hours and contact details.
