You don't have this? In Sweden we have sensors to detect cars, pedestrians and bicycles to shift the lights as appropriate. During rush-hour those features are turned off/discarded in favor of "grid optimized" timings. In Netherlands they prioritize pedestrians and cyclists when it's raining.

We also have LED lights in our traffic lights which I've come to understand is a saftey hazard in USA because snow falls sometimes.

We do have them, but it's so expensive that we only use them on the biggest and busiest intersections. We also switched to LED several decades ago.
