Board of Public Works Meeting Date: September 23, 2021
Daniel Hudson, P.E., City Engineer
Engineering Department
Purchase of five overhead 360-degree vehicle detection cameras to be installed
along the Daniel Webster Highway corridor
To approve the purchase and installation of five overhead 360-degree vehicle
detection camera systems from Electric Light Company of Cape Neddick, ME in
an amount of $104,580. Funding will be through: Department 160
Admin/Engineering; Fund: Prior Year Escrow; Account Classification: 71
Equipment.
The existing vehicle detection cameras at five intersections on Daniel Webster
Highway have reached the end of their useful life, and need to be replaced. The five
intersections are located at Graham Drive, Circumferential Highway near Tulley
Automobile, Bittersweet Drive near Ashley Furniture HomeStore, Dan Chan Street,
and Costco Drive near the Pheasant Lane Mall. We intend to replace the cameras
with new 360 degree overhead GRIDSMART camera systems on the existing mast
arms.
Electric Light Company of Cape Neddick, ME provided a quote in the amount of
$104,580 for the purchase and installation of the cameras. The pricing includes a
discount of $9,600 for salvage of existing equipment. The Division of Public Works
is requesting the approval of this sole source purchase from Electric Light Company
because they have satisfactorily installed similar equipment for the City at a variety
of locations and are a reputable supplier of quality equipment and material with a
good track record in the City.
The proposed camera systems are superior detection devices and will allow us to
assess system performance by gathering traffic counts in real time, enabling us to
make periodic adjustments to signal timings to maximize the efficiency of the
system. In addition, it will enable us to remotely troubleshoot issues, and track and
report on changes in traffic volumes and patterns over time.
