MAR 19-1980 gppK 43 PACE 58, March 6, 1980 MEMORANDUM TO: Board of County Commissioners FROM: Jack G. Jennings County Administrator SUBJ.: Traffic Signal Modification and Installation On February 14, 1980, we received three letters from the Department of Transportation responding to our request for authoriza- tion to modify and install certain traffic signals. The first concerned the relocation of a pedestrian traffic control signal on U.S.1 from just south of North Gifford Road to the actual intersection (enclosure 1). Their recommendation was to remove the control device. They further stated that their review of current traffic volumes indicated a traffic signal was warranted, however, installation would have to be borne by the county. Signal Construction Company estimates the cost of removal of the pedestrian crossing light and the installation of a new traffic signal would be $19,000.00 (see enclosure 2). The second letter at enclosure 3 concerns the light at SR -5 (U.S.1) and 12th Street. We had requested a study to determine if an exclusive left turn signal needed to be added. Their analysis indicated that this was not required. They further pointed out a shortage of signal heads at that location and recommended installation. Signal Construction Company recommended the addition of two one-way three section signal heads to achieve MUTCD standards. They did not agree with DOT assessment that an exclusive left turn signal was not required. They recommended that we ask DOT to restudy this location on the basis of potential danger and increased volumes as well as a more up-to-date accident history. Their estimate of the cost of additional signal heads was $900.00 (enclosure 4). The third letter (enclosure 5) approved our request to replace the flasher at SR -60 and Kings Highway with a fully actuated traffic signal. Again, the costs would have to be borne by the county. Signal -Construction Company estimates the cost to be $22,000100 for this change-fenclosure 6). It is recommended that: 1. The cuxrent pedestrian traffic control signal on U.S.1 and North Gifford Road be removed. 2. We do not replace this with a fully actuated signal at this time. 3. Two (2) one-way three section signal heads be added to the traffic signal system at U.S.1 and 12th Street. 4. We ask DOT to restudy this location in an attempt to justify a left turn signal. 5. We replace the flasher with a fully actuated signal at SR -60 and Kings Highway. ENCLOSURE AVAILABLE UPON REQUEST
