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.

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?

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.

Looking at the car in front and/or a marker on the road surface interferes

I understand Verizon Wireless is lobbying for legislation banning the sudden
use of brakes near intersections as it has become apparent the danger to
VW's patrons. s

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.

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.

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.

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.

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!!!
