880.01 Description. This work shall consist of furnishing and installing a light
emitting diode (LED) signal head or an optically programmed LED signal head.
880.02 Materials. Materials shall be according to the following.
Item Article/Section
a.Light Emitting Diode (LED) Signal Head and Optically Programmed LED Signal Head ............................................ 1078.01 CONSTRUCTION REQUIREMENTS
880.03 Installation. The signal head shall be installed on a post, bracket,
span wire, or mast arm as shown on the plans. Each signal face shall be pointed in the direction of the approaching traffic it is to control and be aimed to have maximum effectiveness for an approaching driver located at a distance from the stop line equal to the normal distance traversed while stopping. The optically programmed signal face shall be veiled according to visibility requirements at the direction of the Engineer. The size of each signal lens shall be 12 in. (300 mm). During construction and until the installation is placed in operation, all signal faces, including any traffic signal backplate, shall be completely covered with an opaque material. The covering material shall be securely fastened so it will not be disturbed by normal inclement weather or wind. The color of the covering materials shall be other than black and shall differentiate the signal as being covered.
880.04 Basis of Payment. This work will be paid for at the contract unit price
per each for SIGNAL HEAD, LED or OPTICALLY PROGRAMMED SIGNAL HEAD, LED of the type specified, and of the particular kind of material, when specified. A signal head with both standard and optically programmed signal faces will be paid for as a COMBINATION SIGNAL HEAD, LED. The type specified will indicate the number of signal faces, the number of signal sections in each signal face, and the method of mounting.
