different traffic light sequences from state to state- cause accidents

wrote: 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. Rear end collisions increase when there are red light cameras. The argument is that the T bone accidents are more serious and are reduced by the cameras. I don'y know if I buy that or not. |

I have little sympathy for someone who rear-ends someone. Defensive driving, you know. |

JamesStep was claimed to have wrote: 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?

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. Again, and I'll type this slowly for you, cross traffic is not a problem if a all-way-red is sustained longer to make up for the shorter yellow light. The obvious problem of people slamming on their brakes and getting rear ended is still a huge problem and it defeats the whole point of yellow lights in the first place, and I'm not in any way condoning the practice of decreasing yellow light timing, but if you're going to argue against something, at least understand the topic. |

I've never understood why roads should not be marked with a line whereby, if the yellow light came on after crossing it you should continue, otherwise you should stop. The position of the line would depend on the speed limit. -- James Silverton Potomac, Maryland |

different traffic light sequences from state to state- causeaccidents
Again, and I'll type this slowly for you... ...if you're going to argue against something, at least understand the topic Geez, we're having a friendly discussion and you hurl TWO insults at me in one post? The reason I didn't address your "increase all-red time" comment was because nowhere in this thread had I seen anyone say that traffic engineers actually do increase all-red time in proportion to the decrease in yellow time. So your comment seemed like a hypothetical, "what if" comment. I agree with you that increasing "all-red" time would probably decrease collisions in the intersection, but as you yourself stated there would still be a problem with rear-end collisions. James |

James I'm not trying to knock anyone in this thread but it's an illustration of how experiences or local customs color one's perspective. There are still many places in the United States that have "zero" all-red times at intersections. When one street turns from yellow to red the cross street turns to green--no delay! In my experience, and this is only based on my limited experience, that is the norm rather than any "all-red" time. -- Gary Visit Lucy & Gary and do the jigsaw puzzle at www.under-1-roof.com/PuzzlePage.html |

that have "zero" all-red times at intersections.... Yep. In the city where I live, most of the traffic lights have no all- red time at all, except for those on roads that have high speed limits. James |

By "sequences" do you mean the arrangement of red, yellow, green. I would
like to know where you have seen different arrangements. For the sake of color blind people I thought there was a standard arrangement unless it is horizontal light with a unique traffic configuration. wrote in message ... After all- since driving on the right side of the road is a national rule-UNIFORM signaling should be one also. demand a UNIFORM national STANDARD for traffic signal design and light sequences!!! email/write your congressman |
