Farah, no, they are not. We chose the junction-to-junction distance, which is not uniform. This more heavily weights longer segments, so we provided length as a feature. For the most part our segments are a mile or less, but we probably should have split up the longer segments as well. The issue is if segments get too short, information can get washed out and accuracy can degrade.
If I had more time to work on this, I could have also separated intersections into their own to highlight that it’s not necessarily a specific segment, but something a dangerous intersection.
