Traffic Control Plans

Signs
Standard highway signs for information,
speed limits, and work zones will assist drivers
in identifying, in designated traffic paths,
such directives as: EVACUATION ROUTE; DO
NOT ENTER; REDUCED SPEED AHEAD;
ROAD CLOSED; and NO OUTLET. Using standard
highway signs for internal construction
worksite traffic control will assist workers in
recognizing the route they are to use at the
construction site.



Traffic Control Devices

Standard traffic control devices, signals, and
message boards will instruct drivers to follow
a path away from where work is being done.
The authority in charge will determine the
approved traffic control devices such as
cones, barrels, barricades, and delineator



Lighting

Flagger stations should be illuminated.
Lighting for workers on foot and equipment
operators is to be at least 5 foot-candles or
greater. Where available lighting is not sufficient,
flares or chemical lighting should be
used. Glare affecting workers and motorists

should be controlled or eliminated.



Work Zone Protections

Various styles of concrete, water, sand, collapsible
barriers, crash cushions, and truckmounted
attenuators are available to limit
motorist intrusions into the construction
work zone.

General
There must be a traffic control plan for the
movement of vehicles in areas where there
are also workers conducting other tasks.
Drivers, workers on foot, and pedestrians
must be able to see and understand the
routes they are to follow. The authority in
charge, Federal, state, or local, will determine
the configuration of the temporary traffic control
zone for motorists and pedestrians. The
construction project manager will determine
the internal traffic control plan within the construction/
demolition worksite. When there
are several projects, coordinated vehicle
routes and communication between contractors will reduce vehicular struck-by incidents.​

 

Training
Flaggers should be trained/certified and use
the signaling methods required by the
authority in charge. Workers on foot, equipment
operators, and drivers in internal work
zones need to know the routes that construc
tion

vehicles will use. Equipment operators

and signal persons need to know the hand
signals used on the worksite. Operators and
workers on foot need to know the visibility
limits and the “blind spots” for each vehicle
on site. Workers on foot should wear high
visibility safety garments designated as class
1, 2, or 3. Workers should be made aware of
the ways in which shiftwork and nightwork
may affect their performance.



Driving

Seat belts and rollover protection should be
used on equipment and vehicles as stated by
the manufacturer.



Flagging

Flaggers and others providing temporary
traffic control should wear high visibility
clothing with a background of fluorescent
orange-red or yellow-green and retroreflective
material of orange, yellow, white, silver,
or yellow-green. In areas of traffic movement,
this personal protective equipment
will make the worker visible for at least
1,000 feet, so that the worker can be seen
from any direction, and make the worker
stand out from the background. Check the
label or packaging to ensure that the garments
are performance class 2 or 3.
Drivers should be warned in advance with
signs that there will be a flagger ahead.
Flaggers should use STOP/SLOW paddles,
paddles with lights, or flags (flags should be
used only in emergencies.) The STOP sign
should be octagonal with a red background
and white letters and border. The SLOW
sign is the same shape, with an orange
background and black letters and a border.
