If you decide to go through the amber on any wide street, there is not enough time to get to the other side within 3 seconds and you have to finish on the red. It takes at least six seconds to cross a street like Woodhaven Blvd and you are only given a three second amber.That's because the yellow interval is calculated to allow enough time for a vehicle approaching the signal to stop. The all red interval is calculated to allow a vehicle that enters the intersection at the end of the yellow to reach the other side before opposing traffic gets a green. Does your 3 seconds of amber take into account someone going downhill and needing a greater distance to stop? No; a downhill grade would increase the minimum yellow time (although negligibly if it's less than 3 percent). Three seconds is adequate for 20 mph, but not for 30 mph. On streets with a 20 mph speed limit, are the ambers shortened to 2 seconds, or is it still 3 seconds? I bet it is still 3 seconds. You would win that bet, because NYCDOT's policy minimum yellow interval is three seconds. There is a lot we can do to reduce accidents like having warning signs before merges and lanes that suddenly become left turn lanes and you have to make a sudden lane shift to get out. True, but we're talking about reducing pedestrian fatalities. |
