Red light cameras and trucking

"Correlation does not imply causation". http://en.wikipedia.org/wiki/Correlation_does_not_imply_causation

The number of rear-end/crashes at any particular intersection varies, naturally.

 

i can think of many roads with multiple stop lights with 45 - 55 mph
none have forced me to drive speed limit yet
or even too fast to stop at the next yellow

 

You, not me, are the one who originally brought up the "85th percentile" notion.

 

1. Can I ask where and from what University you received your degree in traffic design, where specifically you were (are) employed and in what capacity, that you are such a fan of these.

2. So, after I posted earlier, I was over helping my Dad pack to move out of his house. His neighbor, a Sgt. with Northglenn (Colo.) PD, more than 29 yrs in Law Enforcement, 20 of those with Northglenn was over helping us. I specifically asked him about the two red light cameras and the accident rate. He also said that 70% of the red light camera tickets issued went unpaid, unless they were served upon the person by an officer.

A. He said that they have removed the camera at 104th and Melody and 3 yrs ago. But, that when the camera was installed, they were averaging three to four rear end collisions per month. The intersection one block N. of there does not have cameras installed, they have Zero problems with any type of traffic accidents, except in the winter, and that is because it is at the bottom of a slight grade that can become very slick.

B.The camera at 104th and Huron is still installed, they average 2 to 3 rear end collisions at the intersection, specifically in the turn lanes per month. When school is in session (major HS two blocks So. of intersection), the accident rate for rear end collisions of cars coming N.B. on Huron triples. Also, there are three more traffic signals to the North of that specific location, still within Northglenn, they do not have camera's, they also do not have an accident rate anywhere near what that on has.

C. What was the accident rate of tbone or broadside crashes at those intersection prior to and after the cameras were installed. He said, to the best of his recollection, they still average three broadside crashes per month at each of those intersections, he couldn't directly recall what it was prior.

 

Obviously.

 

Yours, from yesterday

Obviously

 

Short light intervals or not, all the fault lies with the person hitting you from behind. They were obviously following too close. They will anticipate the signal and assume the driver in front will go through. The cameras are not to blame for the accidents, it is the idiots in the following vehicles.

 

I agree with you about the changing from green,yellow,red all while your in the middle of a long intersection.I at least try to get the cab thru and lightly cover the brake lights to show I tried to stop. Ive only experienced this quick changing a few times,but agree some lights need to be readjusted.If they didnt have these cameras though ,people in a hurry would run them everytime (after quickly scanning for cops) I think these lights need to be inspected frequently.

 

Watch out in Hannibal and Marshall MO!!! The red light cameras in those towns are revenue generators for the locals, and are specifically set to catch 18-wheelers. Moreover, on every intersection they're set up on the yellow lights are much shorter than normal. Those tickets will be sent to your home state, and they will affect your CDL!
