You have that one right. I had a moron try to merge into the side of my car on the freeway a couple of weeks ago.

Unfortunately, the setups I've seen around here don't take into account the quantity or position of cars on the main street. If traffic is light, they still have a long delay in most cases, though there are exceptions (this is why I wish they would turn to a flashing light after a certain hour). On the other hand, a few will turn quickly, even if a large stream of cars on the main drag is approaching. These things just don't seem to accomodate conditions very well. Hopefully, when my city finally gets around to installing a system, it will be smarter. (I'll admit that many of the trip plate setups here are not part of a central traffic control system, and these are usually the ones that turn more quickly). I actually like the idea of trip plates, and they should work as you describe. But in this area, they do have enormously long waits at side roads, even in light traffic where a left turn could easily be made onto the main street if the light weren't there (2 minutes is a long time when nobody is approaching. I pass this time by counting how many times I could have made a left turn if there had been a stop sign instead of a light). For what cities are paying for these control systems, they could be a bit smarter. I know that they are sophisticated, and are capable of providing almost stop-free driving on main roads while accomodating traffic approaching from side roads, but I'm willing to bet that most local governments (at least around here) want the least cost alternative, rather than what works. I remember when one of our city councilmen was upset because the contractor that was planning on installing the new traffic light system wanted to eliminate a couple of lights. The councilman said that it would turn the road into a drag strip. Now, with the old system, there are 9 lights in about 1.5 miles on this particular street, and they are not synchronized. So, it is apparent that he believes that these lights are a good means of keeping speeds down. I wish that I was in his ward. :) > > : If you are on the main street, the person waiting at the side street > : will finally get the light to change just as you are approaching.

True, but with a strict timed light, a driver can anticipate when the light might turn and adjust speed accordingly. > > Tigress I guess that I should have been a bit better at naming what I was thinking of. Rather than calling them timed lights, I should have referred to them as synchronized. Most older lights work on timers, and the ones around here are very annoying. There's no rhyme or reason to when they will turn red or green. But the old sychronized systems I've seen (and there are a few streets in Cleveland that have these still) do a tremendous job of keeping traffic moving. It's nice to travel non-stop through 4 or 5 miles of a city, especially in a bad neighborhood. Probably the biggest reason I hate all these lights is that I work in the country and don't see too many of them once I get out of town a bit. I'm used to longer periods of non-stop driving. I live in a suburb just south of Cleveland, OH. I rarely travel north because I hate the driving. Traffic light density grows considerably just north of where I live. > -- > These opinions are mine, not those of Georgia Tech.
