That video illustrates the mentality of a lot of our traffic engineers in this country. Instead of setting up the lights in a sequence that allows smooth, flowing traffic at a reasonably fast speed, they seem to have them timed to snarl up traffic by creating unnecessary, repetitive bottlenecks. The newer "on demand" lights are no different - a car pulls up on the side road and instantly, traffic on the main thoroughfare is brought to a halt so that the one lonely car can proceed (and is often making a right turn which can be done legally on red).
That and the excessively long red lights on major routes are why people are intent on pushing the yellow to the limit. For to stop means 2-3 minutes more travel time.
That might not seem like a lot, but it adds up quickly. I can make the 12 mile venture to work at 04:30 in about 15 minutes. It takes almost a half hour to drive home because of traffic lights (and slugs that clog up the road, but that's another issue).
In Illinois where I used to live, the red light cameras issue the most tickets for right turn on red without a full stop. Not a safety issue at all. I just refused to turn on red at these intersections.
The traffic “engineers” answer to congestion is too often to add more and longer lights. This just increases congestion, the analogy is water through a pipe. Constrict the flow and slow it down and the amount of water that goes through is diminished. Same with traffic.
Arrows first is another change they make. When arrows are last and people can proceed when clear there is often no need for an arrow cycle after. Arrows first and big delays on red in all directions is a safety first choice to help guaranty your right to a risk free life. ( I forget the # for that in the Bill of Rights....) And it increases their revenue.
Another fiasco are federally mandated and lefty loved HOV lanes. The occupants of those lanes are generally buses, delivery truck drivers and construction pickups, and moms with their kids. They do little to increase car pooling, only revenue. It’s one of my favorite traffic laws to violate so I can piss off liberals in the next lane.
