Position and orient the flagger station lighting to direct the maximum amount of light toward the flagger and away from the approaching traffic in the near lane. Aim all of the luminaires directly at the flagger. Increase the output wattage or number of luminaires as the luminance from, and number of, surrounding and background lights increases. Do not provide a total output greater than 2,500 watts, unless otherwise directed. 00223.61 183
00223.42Traffic Control Superviso rs - Use traffic control supervisors to oversee the
implementation of the TCP, and the quality and placement of all temporary TCM and TCD used on the Project.
00223.43Automated Flagger Assistance Device - Use the AFAD to control traffic through the
Work Zone and as follows:
Position the AFAD operator’s control location a safe distance from traffic. Install and operate the AFAD according to the manufa cturer’s instructions and as shown in the Plans. Do not use the AFAD to control more than one lane of approaching traffic. If necessary, close additional Traffic Lanes, left turn lanes or right turn lanes approaching the AFAD to limit approaching traffic to one lane.

AFAD illumination shall meet the following requirements: Illuminates the AFAD so the AFAD is visible and discernable as an AFAD from a distance of 1,000 feet. Illuminates the AFAD from above at a height of 18 feet + 3 feet. The light is shielded from approaching traffic. Do not use an AFAD to replace a continuously operating temporary traffic control signal. The Engineer may order adjustments to the operation o f the AFAD or substitute flagging for the AFAD based on traffic delay, field conditions, and safety concerns. When providing an AFAD for each direction of traffic, use AFADs of the same type and from the same manufacturer. When an AFAD is not in use during a work shift either turn it off or switch the yellow lens to flash mode. When the AFAD is not in use for more than one work shift, remove it and all accompanying signing from the R oadway.
00223.45Pilot Cars - Safely operate pilot cars at a prudent speed, and at a speed that does not
exceed that posted on the temporary advisory speed signing.
