Dear Mr. Gonzales:
We have reviewed the City's recommendations and prepared the following comments:
Timing
We agreed with the proposed timing changes as long as the presence detectors
on MacArthur remain as call and extend detectors.
Phasing
We recommend that the original phasing continue to be utilized. After changing
the timings, if you observe continued problems with the left turns on MacArthur
we suggest phasing patterns 4 or 5. We do not recommend patterns 2 or 3.
If there are any other questions, please call me.
Sincerely,
BARTON-ASCHMAN ASSOCIATES, INC.
