The University of Minnesota, Center for Transportation Studies, Accessibility Observatory has been working on such tools to provide a connection between studies and analysis and applicable geospatial visualizations (i.e. noise pollution, access to jobs within 30 minutes, access to food, etc.).

I'm surprised there isn't more of this already published and well known, such that you can go on Zillow and see such things.

Pure speculation, but perhaps this would only detract from more sales and revenue-generating turnover?
