How do the signals operate when you don’t coordinate?
When signals are not running as part of a coordinated system, they are set to run in a “free mode”. When this happens, each intersection operates independently and responds to the individual traffic demands at the intersection. The signal will rest in green for the major street if there is no other activity at the intersection. This operation is actually the most efficient when there is low volume, because it can minimize delays for minor movements and quickly get back to the green for the major street.

7. Does coordination “break” at major intersections because the cross street volume is also very high?
8. Sometimes I have to wait almost 1-½ minutes (but can seem like 5 minutes) to get a green on a side street or a left turn even when there seems to gaps in traffic. Why?
