Re: a
Dear Mr. Wilson:
Enclosed is a copy of the traffic signal study that war£anted
the signal installed at the above referenced intersection.
After the City of Coppell determined that a traffic signal was
warranted at the intersection in May 1984, the City used their
own funds to install the signal because we understood that
Dallas would not fund the installation costs.
Since 1984 the land development and traffic volumes generated by
that development have increased enormously. The fact that Moore
Road is currently the only north/south thoroughfare in the
residential area until Mockingbird Lane or MacArthur Boulevard
is completed, we see this signal as vital to the needs of
Coppell in order to move traffic smoothly during the peak hours.
On behalf of the City of Coppell, we respectfully request that
this signal not be removed until the matter can be thoroughly
discussed between the two cities.
After your further consideration, please advise our office
of your determination on this matter so that we may inform the
Coppell City Council, who can in turn properly inform their
citizens. Also, please furnish a copy of your traffic warrant
study so that we may compare it with our study.
Thank you for your attention in this matter.
Since~r~y

SIG.NAL WARRANT ANALYSIS:
The traffic volume data was applied to the Traffic Signal Warrants given in the
Manual on Uniform Traffic Control Devices published by the U. S. Department of
Transportation. In order to have a signal installed, an intersection must satisfy
at least one of the signal warrants. The warrants are listed below:
