This map comes from Volume 3 of “Emergence and Growth of an Urban Region: The Developing Urban Detroit Area” completed in Constantinos Doxiadis and associates. The project was a collaboration between The Detroit Edison Company (DTE), Wayne State University, and Doxiadis Associates. Being that the 3 volumes (each around 400 pages) were privately funded the plans and ideas never came to pass.

If you compare the above Doxiadis map and plans with the most recent Detroit Future City (DFC) plan there are some striking similarities beyond color scheme. The main differences seem to be that Doxiadis did not make a plan for a future with continually decreasing population where the DFC includes large swaths of ecological and green land uses that plan for no people.
