Crappy thing is I got nabbed ( $158) for taking a right hand turn on red because I didn't come to a full and complete stop.---- I don't see this as a dangerous move, as I had checked and the coast was clear.
Of course I am a criminal and should be treated as such.
In theory I don't mind red light cameras or healthcare for all or any one of a number of high sounding ideas, it's the implementation that is the issue.
Here is a compilation of some posts on this same subject from a local Porsche forum.
"So I looked that up, and the Texas Manual on Uniform Traffic Control Devices, Section 4D.10 "Yellow Change and Red Clearance Intervals" states that "The duration of each yellow change interval shall be determined using engineering practices." - Wow, don't overwhelm us with math or tables or anything.
It further says "Engineering practices for determining the duration of yellow change and red clearance intervals are found in ITE's "Traffic Control Devices Handbook" and in ITE's "Manual of Traffic Signal Design" (see Section 1A.11)." Well guess what - BOTH of those books are not online, and can only be purchased.Convenient! Only $93.75 each! A bargain!
Under Guidance though, the Manual on Uniform TCD says, " A yellow change interval should have a duration in the range of 3 to 6 seconds. The longer intervals should be reserved for use on approaches with higher speeds." His intersection had a yellow interval of 3.4 seconds but further study showed it ought to be 5.4 - 5.7 seconds
A civil engineer had this to say - "Regardless, you have correctly identified that the yellow for that intersection is too short. The design guideline we followed was I second of yellow for every 10 MPH of posted speed on the approach. The allred period is not relevant to why the yellow should be 1 second per 10 MPH. This guideline was developed after detail study on perception reaction time combined with how long it takes for a driver to safely bring a vehicle to a stop when he or she sees the light turn yellow from green. The design guideline was also developed for "the worst case scenario" of a legally fully loaded truck (an 18 wheeler for example) to come to a safe stop from traveling at the legal speed limit of 45 MPH. At a yellow of 3.4 seconds, it is easy to argue that the yellow interval is way too short for safety."
Then this idea for defense came up:
"As I understand it, every municipality is required to have a Licensed
Professional Engineer attend to various tasks and put his/her
professional neck on the line by affixing his/her official seal to
documents For small towns that engineer may be a
part time consultant but for larger cities there are entire engineering
departments with multiple engineers and, hopefully, appropriate
specializations.
You can file a complaint against an individual engineer or a
governmental body. Please start at http://www.tbpe.state.tx.us; there
is a large "FILE A COMPLAINT" button along the right side. Please read
the verbiage there in its entirety especially as regards governmental
bodies.
I would think you could properly demand of the municipality in question
that they give you a copy of the settings of the traffic control
equipment showing the approving engineer's seal which will give you
his/her name and registration number. Getting that document may well
itself be a legal fight and I can't offer any wisdom there. Now my
logic here is that, since the law verbiage you cite specifically uses
the term "engineer*", a Licensed Professional Engineer must review and
approve those settings. You might, for all I know, find that
municipalities believe that a police or judicial official can choose
those settings and there may not even be a record of them. In that
case, I hope the PE board will firmly coerce the municipality to comply
with state law regarding the Practice of Engineering. The board has
done so in the past (of course, the board members are appointees, and
one can only hope they will resist political pressure). If there are
documents with an engineer's seal and the settings do not match the
document I hope that's a sufficient defense but moreover I think that's
still a basis for a TBPE complaint. If the settings are not in keeping
with the engineering specifications that is certainly a basis for a TBPE
complaint against the engineer and again I hope that becomes a
sufficient defense against the citation.
