Realistic Speed Limits for Metro Chicago

Please refer to attached Chicago "speed study" results and our rebuttal of the recommended limits.

In summary:

 - USDOT expert software called USLIMITS2 recommends a 75 mph for most metro Chicago Tollways (none below 70 mph)
 - 70% of other states have URBAN speed limits of 65+ (65, 70, 75 or 80 mph - urban)
 - Speed studies predict a violation rate of 80% at the proposed 60 mph limits (vs 25-30% at a 70 mph limit)
 - The recommended 60 mph limit would be the 20th percentile speed vs the standard 85th percentile benchmark
 
For more detail on the above points see attached documents below for excerpts from the speed studies and our analysis.
