Why wouldn't you just use the default for every traffic light?

In this video I go over each of the nonstandard step switch conditions, and provide examples for when you'd use each of these. The examples I give are: * ramp meters
* bus unbunching signals
* transit signal preemption
* skipping phases of a 4way junction
* staggered pedestrian crossing
* restonred pedestrian crossing

This video was originally going to be 4 separate videos, but instead it was just 1 video that took me over 4 times longer than usual to record and edit. I have learned from my mistake and shall go back to short videos in future.
