That is a very difficult corner to understand. I would be amazed if the incident didn't involve a bike moving east. It is very dark and the traffic signal is very far west of the corner. As well, the entire site is not a straight foursquare intersection. If turning from Junction westbound onto Michigan you cannot even see the signal above. Only cars that have been heading west on Michigan Ave - stopped well east of the signal- can see the light change.Just a bad place and poor signage and sight lines.
