The rule of thumb for yellow light intervals is one second for each ten MPH of the speed limit leading up to the intersection. AAA found that the city of New York has been shaving that interval by as much as half a second and therefore not giving drivers "...ample time to get through the intersection."
Seems the city that never sleeps also never stops trying to suck money out of the huddled masses yearning to breathe free. The city brings in a lot of tribute from those pole cameras. There are 170 cameras snapping happily away at 150 intersections. They bring in nearly $50 million each year and...and...Mayor Bloomberg wants to up the covered intersections to two hundred and twenty-five.
