Just some Cincinnati-themed output from some work I’ve been doing recently… this is a map of the percent of streets, by length, which are dead-ends (for cars).
Data is from OpenStreetMap. The darker area on the map is defined by a street density of greater than 4km of roads per km2. The X and Y scales are in kilometers. Now a few other random cities for comparison. Smoothing was done with circular gaussian kernels with a standard deviation (bandwidth) of 2km.

Atlanta:

Much more on this to be presented at the NACIS 2016 annual meeting this October!
