different traffic light sequences from state to state- cause accidents
schrieb
Would you like to comment on (or defend) a ONE SECOND YELLOW LIGHT next to a ticketing camera?! http://knowledge.fhwa.dot.gov/cops/opspublic.nsf/discussionDisplay?Open&id=7CFB51E04C66D86685257058 00461560&Group=Signs&tab=DISCUSSION There is a recommended amber phase duration of 3 to 6 seconds. Ask whoever programmed the traffic lights why they did not follow the FHWA guidelines. Jochen |

different traffic light sequences from state to state- causeaccidents
Would you like to comment on (or defend) a ONE SECOND YELLOW LIGHT next to a ticketing camera?! Ah-ha, we finally know the reason for your original "write your congressman" post. I doubt if it was really a "one second" yellow, no one would have time to stop and there would be constant collisions. But if it was less than 3 seconds then you certainly have a legitimate complaint. Short yellow lights can not only lead to unfair traffic tickets, but they can also lead to accidents. If it was too short then the traffic engineer wasn't following the guidelines. In fact in some states I believe the law says that 3.5 seconds is the legal minimum. James |

different traffic light sequences from state to state- cause accidents
I haven't lived in Massachusetts in 20+ years but when I did live there they
had a red and yellow at the same time, too. I don't recall for sure but I think it meant something like all intersection traffic was stopped and pedestrians could cross in either direction. (The standing joke at the time was red=we suggest you stop and red & yellow at the same time=we think that you should stop! I remember when I first moved to Boston sitting at a red light waiting for it to turn green and having a Boston cop pull up behind me and tap his horn. When I didn't move he got out, walked up and asked what I was waiting for. I politely told him that I was waiting for the light to turn green and he, as politely as a Boston cop could, informed me that if there was no traffic at a red light that I should just treat it like a stop sign and go thru after I stopped. And, no this wasn't in the middle of the night--it was in the middle of the afternoon in Southie! I never did really learn to do it that way--I guess all my earlier experience of stopping at red lights stuck. I don't have a problem doing the "right on red". "Straight on red" was a different story!) -- Gary Visit Lucy & Gary and do the jigsaw puzzle at www.under-1-roof.com/PuzzlePage.html "James Silverton" wrote in message ...

True enough but what I meant was that they don't differ in patterns like, for instance, in Germany where there is a red and yellow combination to let people get ready to let out the clutch (or whatever you do with it :-) -- James Silverton Potomac, Maryland Email, with obvious alterations: not.jim.silverton.at.verizon.not |

A light on a 50 mph road would require a longer light than one on a 25 mph road. |

But if it was less than 3 seconds then you certainly have a legitimate complaint. Why would there be constant collisions? Increasing the all-directions-are-red time by the same amount the yellows were reduced would avoid cross-traffic collisions, although not helping those tailgating too close to stop. |

I doubt if it was really a "one second" yellow, no one would have time to stop and there would be constant collisions. Why would there be constant collisions? Safety guidelines (and in some cases state law) require around 3 to 3.5 seconds minimum for yellow lights, to give people time to stop safely. Otherwise you'll have people who can't stop in time and go thru a red light and collide with cross traffic, or if they slam on their brakes then possibly getting hit by the car behind them. |

I don't doubt that you are correct but I don't remember ever seeing that red-yellow combination. My son lived in Somerville (just outside of Boston) for awhile. I always knew where his street was because the street just before his had a flashing green light. It constantly flashed green until a car tripped it when exiting the side street. |
