The map includes surface parking and above ground parking structures which are marked on OpenStreetMap and/or visible in Google Maps imagery. It does not include street parking, underground parking, and podium parking (parking lots that take up only the first several floors of a building).
The parking score measures how a city’s parking lot land use compares to other cities with similar metropolitan area populations.
A low parking score is good and means that the city devotes less land in its central neighborhoods to parking than the average. Conversely, a high score means that more land is dedicated to parking compared to the average for a city of that size.
This scoring system was created to evaluate cities on an equal basis and should not be used outside of this context.
“Central city” is a term invented for this map to encompass the densest, most centrally located, and most valuable real estate in a metropolitan area. It is a blanket term for a city’s central business district, downtown, financial district, or adjacent connecting neighborhoods of interest.
For example, New Orleans’s Central Business District seamlessly connects with the World Renowned French Quarter Neighborhood. These areas were combined into the Central City of New Orleans.

You can embed our map by using an iframe, which is a way to embed other websites directly into your website.
First, find how to embed iframes with your website provider. For example, Wordpress sites should use a Custom HTML code block . Try searching for the name of your website provider and 'iframe', like 'Squarespace iframe'.
Then, include code like the following block. However, change the value for "src" to the link to your specific city, which you can get by clicking the link icon in the top-right corner of the map's header bar.
<iframe src="https://parkingreform.org/parking-lot-map/#parking-reform-map=salt-lake-city-ut" width="100%" height="525px"></iframe>
You may want to adjust the "width" and "height" attributes. However, we do not recommend setting the height taller than "525px" because it makes it hard to scroll on mobile.
