— Report: more transit oriented development can benefit Atlanta region | Atlanta Business Chronicle, 10/8/14
An incredible series of interactive maps from the University of Minnesota’s Accessibility Observatory site shows where the hotspots are for jobs that can be easily reached by transit and walking. They look at 46 US metro areas and judge the “30-minute accessibility values at the Census block level.”
In the above capture from the Atlanta map, the cool colors show where fewer jobs can be reached in 30 minutes, with warm colors showing the places with densities of jobs that are more walk/transit friendly. The site notes that “travel times include walking, waiting, riding, and transfers.”
Many of the hot spots in the center of the city are no-brainers for anyone who knows where the MARTA rail lines and the office clusters converge. But I was happily surprised to see those clusters of orange in the southwest end and in east Atlanta.
The most striking thing about the image, to me, is that the findings don’t seem to have any geographic correlation to other visualizations I’ve seen, such as the Racial Dot Map, the class map, and the home values map. Accessible jobs cross over the boundaries of those geographic divisions in a fairly even way.
This seems to be one area in which the cultural and economic divides of the city don’t carry as much weight as does the built environment and zoning. Build transit lines and sidewalks, and zone for densities of commercial buildings, and the accessibility will follow.
