Why traffic signal technology are still so outdated in much of the world?

Though they make great sense in newer communities. And
LV, aside from downtown or the city center, is mostly a newer spread out place where there are lights with irregular traffic patterns with cross streets which doesn’t need a green light regularly since no one is there.

Though it’s true that some places do keep the speed down by keeping lights red unless it’s approached below a certain speed.

But here you are encouraged to drive over the speed limit to make the lights. Either that or go real slow so the light cycles through the alternate street. You would probably get shot for doing so. A lot of people here like guns and seem to enjoy using them.

I'll leave that laying there next to the non-existent trip plates on a Las Vegas street.

OK, so why are there stretches of road that a driver will get multiple red lights, one after the other, in succession?

If they can time them this way, they could also time them so drivers get all green lights in succession too...which moves traffic more effectively, red or green lights? LOL

I agree. They seem to be not understanding the simplicity of fixing the problem.

One of his quotes:

"In this business there are very few problems that can't be solved with some yellow paint and a little bit of common sense."
