Question on the source of Traffic Road data

In README.md, you say the traffic data is from these two:

• Chicago Traffic Tracker - Congestion Estimates by Segments: Geo information of traffic segments of Chicago arterial streets (nonfreeway streets).
  

• Chicago Traffic Tracker - Congestion Estimates by Regions: Geo information of Chicago Regions.
  

In Chicago_Traffic_Crashes.ipynb

But I find that the road data you use in Chicago_Traffic_Crashes.ipynb is transportation.

And these is no detail description on that page.

So, what is the traffic data you actually use?
If you use transportation data, can you give me more information about that dataset?

Thanks.
