Excuse the anecdote over links to actual studies, but one of my old roommate's father worked on traffic light systems that time the yellow light based on the speed of cars approaching. They extended the time for cars that couldn't stop safely or that were accelerating to get through the light. This apparently reduced accidents at those intersections.
- inanutshellus 7y agoYup, but that's custom tech your municipality sprung for. In the '90s there was a town I lived in whose lights identified your approach and changed to green for you as you arrived (at low density times). If you went the speed limit, you never stopped or slowed down. I've pined for that tech in every place I've lived since. :-D
- jagged-chisel 7y agoI seem to run across the opposite: I'm approaching a green on a night with practically no traffic, and the thing changes, timed to go red before I could get through the yellow. So I sit, waiting while it's green the other way, and no traffic in sight.
- dsfyu404ed 7y agoTie it into a weather API so we can have a longer pause between red and green depending on weather conditions to give people time to slide through the intersection.
