I was curious about ADA-compliance and system usage for the CTA.

By my calculations, there are 53 non-ADA-compliant "L" stations and 83 ADA-compliant ones (counting all Brown Line stations as compliant even if they're still under construction).

So 61% are compliant.

But those 61% of stations account for 65% of "L" ridership. Not too bad - at least the busiest stations seem to be getting priority. That percentage is actually slightly higher, since I took annual stats for 2008 and some of those Brown Line number would be skewed last year.

Looking over the stats, the non-ADA Blue Line subway stations and North Main stations would yield the biggest impact for ADA improvements.
