The acronym AWG stands for what ? correct answers American wire gauge
Americans with disabilities act of 1990 (ADA) is ? correct answers Requirements ensuring equal
opportunity for persons with disabilities and employment, state and local government services,

Changeable message sign is for what ? correct answers Also known as variable message sign
(VMS) and dynamic message sign (DMS) CMS are traffic control devices used for traffic
warning, regulation, routing and management, and are designed to affect the behavior of motorist
( thus improve the flow of traffic) by providing real time highway related information
What is a (Beacon)? correct answers A highway traffic signal with one or more signal sections
that operates in a flashing mode.
The acronym (ITS) stands for what ? correct answers Intelligent transportation systems
intelligent transportation systems (ITS) what does it do? correct answers Improves transportation
safety and mobility and enhances productivity through the use of advanced information and
communications technologies. ITS encompass a broad range wireless and wire line
communications based information and electronics technologies (ITS)
,What is a (major street) ? correct answers The street normally carrying the higher volume of
vehicular traffic
The acronym (MMU)stands for ? correct answers Malfunction Management Unit
Malfunction management unit is ? correct answers A device used to continually check for the
presence of conflicting signal indications and other malfunctions and to provide an output
response to conflict or malfunction. MMU is an advance type of conflict monitor that also
communicates and monitors controller function.
What is a minor street? correct answers That street normally carrying lower volume of vehicular
traffic
What is "offset" correct answers The time difference, or interval in seconds or percentage of
cycle length between the start of the green indication of the coordinated phase and the system
reference signal
What is a "platoon" correct answers A group of vehicles or pedestrians traveling together as a
group, either voluntarily or involuntarily, because of traffic signal controls ,geometrical or other
factors
What is a "preemption control"? correct answers The transfer of normal operation of a traffic
control signal to a special control mode of operation.
What is a "Queue length "? correct answers Number of vehicles stopped or slowly moving in a
line, where the movement of each vehicle is constrained by that of the lead vehicle
What is a "signal warrant? correct answers A threshold condition that, if found to be satisfied as
part of an engineering study, shall results in analysis of other traffic conditions or factors to
determine whether a traffic control signal or other equipment is justified
,Which certification has level II and Level III ? correct answers Traffic signal level II bench
Traffic signal level II construction
Traffic signal level II design
Traffic signal level II field
Traffic signal level III Bench
Traffic signal level III Electrician (field)
(Traffic signal phase )is ? correct answers Specific assigned timing function in the traffic signal
controller.
Are phases numbered 1 -8 ? True or false ? correct answers True
Even number phases are typically assigned to what movements? correct answers Through
movements
Phases 2-6 are assigned to ? correct answers Major streets through movements
Odd numbers ( 1,3,5,7) phases are assigned to what? correct answers Left turn phases
An intersection that has four through phases and four left turn phases are considered how may
phases together ? correct answers Eight phase intersection
Each phase is comprised of intervals ?
True or false ? correct answers True
(Interval )is based on? correct answers The amount of TIME that a particular indication is given
during a phase
Another words, the total time assigned to a specific display.
, An example of an ( interval ) is? correct answers " the amount of time that a green indication is
given during a particular phase. " (know as a "green _______ )"
(Ring) in a traffic signal controller is? correct answers A Series of conflicting phases that occur
in simultaneously( same time ) with each other
What are the two typically ( ring ) that a traffic controller have ? correct answers "Single-ring" or
"dual ring"
What are other ( rings ) that are rarely used ? And when are these types of rings used for? correct
answers 3 or 4 rings &
(used for two or more separate intersections are controlled by a single controller)
What is a ( barrier) ? correct answers Is a boundary point in the preferred sequence. Barrier that
separates something so it won't have in the same time.
How many (barriers) does a "dual ring controller" have? correct answers Two , one for leaving
the MAJOR street and one for leaving the MINOR street.
_______ ensure that green indications will not be given to conflicting movement at the
intersection at the same time. correct answers Barriers
What is a ( concurrent phase) ? correct answers Are movements that happen at the same time
because do not conflict ( collide) with one another.
Example of a ( concurrent phase ) correct answers A Through movement and a adjacent left turn
movement can move on the same time.
A traffic cycle / ( cycle length ) definition is ? correct answers Is the total elapsed Time between
the start of a specific display until the display comes up again.
Example ( if the cycle starts at the beginning of a green display it will end when The same green
display begins again after the red and yellow displays have been given.
