"Once lit, the phase indicates nearby drivers should simply follow the car (AV or human) in front of them, instead of trying to anticipate something like a yell

"Once lit, the phase indicates nearby drivers should simply follow the car (AV or human) in front of them, instead of trying to anticipate something like a yellow light’s transition time to red."
I dont know what this means but it sounds similar to the green wave light that we have here in the netherlands. All it is is a lit green double wave that tells you that the very next traffic lights going straight will be guaranteed to be green. This way you dont have to anticipate breaking even if you can see the green light has been on for an entire cycle.
This is usefull because you can chain intersections so the worst case is that you have to wait two cycles on the entire chain, coming on and going off.

- Tomte 3y agoAnd in my town the main road has an anti-green-wave. If you‘re not excessively speeding (like three times the speed limit), you‘re guaranteed that every second or third light will be red. Citizens asks the town administration if they have heard of green wave. Yes, they have. Having a red light every few intersections is supposed to curb speeding. It‘s beyond stupid, especially since people living in the houses lining that road have enough noise and exhaust already.
- Out_of_Characte 3y agoThat seems awfull. Here in the netherlands, most automatic signals dont really care about speeding. Though alot of green waves are also designed with trucks in mind. So this puts clear upper and lower limits on timings.
