This is unsafe for pedestrians. The yellow light means "Clear the intersection," not "Slow down." The purpose is to give time to people crossing the sidewalks to finish walking over to the other side. Shortening them is a safety hazard for pedestrians like me who don't own a vehicle. I don't live in Florida, but this is shameful and disgusting.
The yellow light does mean "clear the intersection", but its purpose is not to give pedestrians time to finish their crossing. There are many things that have to clear the intersections, not just pedestrians. Plus, the decrease they talk about in Florida is only by fractions of a second, anyway. Here in Toronto, we have an additional two seconds of "all red" light after any yellow lights, to give time for left-turnin…
The decision was made for poor reasons. There's nothing preventing them from making the same decision for the same reasons again, effectively increasing the reduction of time. It's important to call out poor behavior in government lest, even if it's slight, lest it become institutionalized and then exacerbated.
