This isn't 100% true. There are many small, rarely traveled, residential streets (i.e. only the people who live on the small street come/go from there) that feed into high traffic, multi-lane arteries.
Parent comment's scenario is pretty common due to detection based switching. 99.99% of the time this is desirable because it keeps the artery flowing.
If there's a crosswalk button across the artery, you'll many times find a person running out of their car to hit that to force the light change.
- grigri907 2y agoAre these traffic signals all programmed with controls unique to each intersection?! Certainly many places have signals that are coordinated for several blocks, but in my experience, more often than not, intersections appear be controlled by local sensors.
- irjustin 2y agoAgreed, generally only in metro areas with the few miles leading in/out do you find coordinated traffic systems. Vast majority of road length is in suburbs where local sensors dominate. Had a few friends who went to civil eng and two eventually joined city planning. Was fun to discuss their problems. Lack of funding really was the common thread. It's always lack of money.

- afiori 2y agoThe solution to this issue is that that crossing should not exist or should be a right-turn only crossing. This is also the perfect case for roundabout (one major artery and one or more low volume streets)
