From the Accessibility Observatory‘s new report: Access Across America: Transit 2014. This map uses transit data from January 2014, so is pre-Green Line. A report on the effect of the Green Line on Transit Accessibility will be out soon.
Full disclosure, I am a co-author on the report with Andrew Owen.
The efficient and fair thing to do would be to allow more housing units in the yellow, orange, and red parts of the map.
while also shifting the funding from things like 494 Plymouth lane expansions, etc to improving bus service in those areas. We’ve spent billions making it possible to live beyond the 494 beltway and still have access to more jobs in 30 minutes of peak hour driving than someone living in Minneapolis taking transit.
