Alex
I attached the specs for traffic lights that we used on our most recent project. It's 65 pages, but I wasn't
sure what all you needed. There is one change that we recently made. It concerns communication
methods. On page 6 -22 under "2 -8 Communication" we now require one of the ports to be ethernet.
We also require a confirmation light on the mast arm.
Andy Watson with Naztec knows what we require probably as good or better than we do. He can be
reached at andygnaztec.com
If you have any other questions let me know.

Ken,
Spoke with Per Birdsall this afternoon and he instructed me to get with engineering. I'm looking for
the Coppell standards for the traffic signal controller and cabinet. Any help would be greatly
appreciated.

2 7 3 S Using the above information in fixed force -off mode, the coordinator must perform the
following functions for each pattern.
1) Guarantee the coordinated phase(s) programmed time will be serviced in their
entirety to achieve coordination between intersections (when not correcting) The
programmed time of the first coordinated phase in the phase sequence shall start at
T
2) Calculate each phase's force off point (the point at which a phase's Green must
terminate, in order to not violate the following phases' programmed times)
3) Calculate the beginning of each phase's permissive window (the point in the cycle
when the coordinated phase is allowed to yield to each corresponding phase)
4) Calculate the end of each phase's vehicle permissive window (the point proceeding
a phase's force off point by its minimum time and the prior phase's clearance time)
Any phase receiving a vehicle call before the end of vehicle permissive window will
be serviced during the current cycle
S) Calculate the end of each phase's pedestrian permissive window (the point
preceding a phase's force off point by pedestrian Walk and pedestrian clearance
Mmes and the prior phase's clearance time) Any pedestrian call received by a phase
before the end of pedestrian permissive window will be serviced during the current
cycle up to the beginning of the phase vehicle green.
6) Guarantee that each phase's programmed time is serviced in full if a call was
received before the beginning of permissive window, and the phase does not
terminate due to Gap out.
2 7 3 6 Using the same information in floating force -off mode, the coordinator must operate in
the same manner as fixed force -off mode, except that if a non - coordinated phase 1s
entered early, it will remain active only for the time programmed in the split time.
Automatically setting the max timer in each split to accomplish this function is
acceptable
2 7 3 7 once the user -- selectable data for phase service is entered, the controller unit shall test
the plan to insure that the plan does not violate any minimum times based on the
specified numbers and cycle length. If a faulty plan is detected, the controller unit shall
shove an error code indicating the problem. If the error is not corrected, the controller
unit shall run in free operation mode whenever the erroneous plan 1s selected. If
actuated pedestrian movements are programmed, the coordinator shall ignore errors
detected due to the pedestrian Walk and clearance times violating the phase split time
for any actuated pedestrian. The controller must have a diagnostic screen that lists any
of the TS 3 5, §2 5 11 status reasons for free mode operation and must also have a
diagnostic status screen. The diagnostic screen shall include all relevant information
about the failure that resulted in free mode operation. As an example, if the cycle length
does not equal to the sum of the splits, then the indication would be cycle failure and
the sum of the splits would be displayed.

Yield points are calculated at a 6% increment for each phase following the
coordinated phase
3) "N.J " mode, which allows a single permissive interval to yield to all phases from
the coordinated phase
4) "Permissive fixed ", which allows three (3) permissive periods to be defined, as well
as a force -off for each phase

. reasonably dry, completely free of debris, and without any sharp projections, edges, or
short bends. The conductors shall be installed in such manner and by such methods
6 -54 Technical Specifications &
Description of Pay Items
.� as to insure against harmful stretching of the conductor or damage to the insulation
and shall conform to the recommendations of the cable manufacturer The Contractor
shall furnish, at the request of the Engineer, at least two copies of the manufacturer's
-- recommendations, including methods of attaching pulling tension per conductor size
and per radius of conduit bend, and the type of lubricant to be used.
11 1.2 All cables in a given conduit run shall be pulled at the same time and the conductors
shall be assembled to form one loop in such a manner that the pulling tension is
distributed to all the cables. Long, hard pulls will necessitate the use of pulling eyes.
For short runs, the cables may be gripped directly by the conductors by forming them
into a loop to which the pull wire or rope can be attached. The insulation on each
conductor shall be removed before the loop is formed The method used will depend
on the anticipated maximum pulling tension in each case
I 1 1 3 In many instances, existing conduits which contain signal cable are to be used for the
installation of new cables In such locations, the existing cable(s) may be used to pull
in the new cables Should the Contractor desire to install new cables without
removing the existing cables, the new installation shall be done in such a way as to
prevent damage to the existing and/or new cables. In the event of damage, the
Contractor shall bear the responsibility of replacement of defective cables.
11 1 4 The manufacturer's recommended maximum pulling tensions shall not be exceeded
under any circumstances If so required by the Engineer, the Contractor shall insert a
dynamometer in the pull wire as the cables are being pulled into the conduit to
demonstrate that the maximum tensions are not being exceeded. The cable shall be
fed freely off the reel into the conduit without making a reverse curve At the pulling
end, the pull wire and or other suitable devices shall be used as required to reduce any
hazards to the cable during installation. The cables shall be adequately lubricated to
reduce faction and further minimize possible damage Such lubricants shall not be
the grease or oil type used on lead sheathed cables but shall be one of several
commercially available wire pulling compounds that are suitable for these kinds of
cables. They shall consist of soap, talc, mica, or similar materials and shall be
designed to have no deleterious effect on the cables being used.
11 1 5 The cables shall be neatly trained to their destinations in manholes, cabinets, pole
bases, pullboxes, and all other terminations The cable manufacturer's recommended
values for the minimum bending radii to which cables may be bent for permanent
training during installation shall be adhered to These limits do not apply to conduit
bends, sheaves or other curved surfaces around which these cables may be pulled
under tension while being installed. Larger radius bends are required for such
conditions.

mix that produces a finished product ready for use)
1 3 The materials shall have the following characteristics
a. When in place for use, the markings shall not be slippery when wet.
b The material shall have adhesion to the surface sufficient to prevent
teanng, roll -back, shrinkage and lifting under all weather conditions.
c When in place, the material shall not exhibit a tacky or sticky surface
d. Cold ductility of the material shall permit movement of same with the
normal shifting of the road surface without chipping or cracking.
e The markings shall retain their original color, dimensions, and
position (relative to surface) under normal traffic conditions at road
surface temperatures from O °C (+ 32 °F) to 70 °C (158 °F)
when applied, the film material shall be 0 012" thick and essentially
have a uniform cross section with uniform density and material quality
throughout the thickness. The material shall be 95 percent free of
-- voids and holes and virtually free of blisters.
g. Markings in place shall be reflectorized internally (premixed glass
beads imbedded in film) Texas Test Method Tex -828 -B shall show
uniform retrodirective reflectance throughout the markings.
