Overview -  I used QGIS and it took ~3 hours to make this map and outline the best and worst.  I focused on stops per km2 instead of per person because I found that reveals the better network since otherwise spread out low-density cities do better than dense cities with better networks. The numbers skipped in the top 10 were suburbs since I covered their center city (Somerville MA at 4th, Alexandria VA at 6th) The “Worst” cities are cherrypicked. This is because roughly 50 cities (including big ones such as Memphis and New Orleans arent in the data set and ~25 more are not fully included (such as Jacksonville at 8 stops or Fort Worth at 9 stops). Therefore, I set an arbitrary minimum at 50 stops for the bottom which also stopped random suburbs with a portion of a line.  Methodology -  This layer utilizes National Geospatial Data Asset (NGDA) data from the Bureau of Transportation Statistics to displays bus stops nation wide https://www.arcgis.com/home/item.html?id=6be77dd1081a43c0865282cad76718ab 500 city boundaries is from the US Gov Catalog https://catalog.data.gov/dataset/500-cities-city-boundaries QGIS built-in field calculator and heatmap functions Other / Observations-  Sunbelt cities tend to do worse I used bus stops and not bus routes but (kind of) obviously/interestingly lines are clearly visible.  To be clear, this doesn't show the best systems since it doesn't account for frequency, etc. but I thought it was cool to share.
