One definition of a Traffic cycle / (cycle length) is?-ANSWER The total elapsed Time
between the start of a given display until the display comes up again.
Example if the cycle starts at the start of a green display it will end when The same
green display commences again after the red and yellow displays have been given.
What does AWG stand for? - ANSWER American wire gauge
ADA-Americans with disabilities act of 1990 is? - ANSWER Requirements ensuring equal
opportunity for persons with disabilities and employment, state and local government
services, Public accommodations, commercial facilities and transportation
What does (CMS) stand for? - ANSWER Changeable message sign
Changeable message sign is for what ? - ANSWER Also called 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 behaviour
of motorist thus improve the flow of traffic by providing real time highway related
information
What is a (Beacon)? - ANSWER A highway traffic signal with one or more signal sections
that operates in a flashing mode.
The acronym (ITS) stands for what ? - ANSWER Intelligent transportation systems
intelligent transportation systems (ITS) what does it do? - ANSWER 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) ? - ANSWER The street normally carrying the higher volume of
vehicular traffic
The acronym (MMU)stands for ? - ANSWER Malfunction Management Unit
Malfunction management unit is? - ANS 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.
Minor street? - ANS That street normally carrying lower volume of vehicular traffic
What is "offset" - ANSWER 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" - ANSWER 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"? - ANSWER The transfer of normal operation of a traffic
control signal to a special control mode of operation.
What is a "Queue length "? - ANSWER 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? - ANSWER 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 ? - ANSWER 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?-ANSWER Specific assigned timing function in the traffic signal
controller.
Are phases numbered 1 -8 ? True or false?-ANSWER True
Even number phases are typically assigned to what movements? - ANSWER Through
movements
Phases 2-6 are assigned to? - ANSWER Major streets through movements
Odd numbers ( 1,3,5,7) phases are assigned to what? - ANSWER Left turn phases
An intersection that has four through phases and four left turn phases are considered
how may phases together ? - ANSWER Eight phase intersection
Each phase is comprised of intervals?
True or false? - ANSWER True
(Interval )is based on? - ANSWER The amount of TIME that a particular indication is
given during a phase
Other words, the total time assigned to a specific display.
An example of an ( interval ) is? - ANSWER " 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? - ANSWER 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 ? - ANSWER "Single-ring"
or "dual ring"
What are the other (rings) that are rarely used? And what are those kind of rings used
for? - ANSWE 3 or 4 rings &
(used for two or more separate intersections are controlled by a single controller)
What is a (barrier)? - ANSWE 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? - ANSWER 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. - ANSWER Barriers
What is a (concurrent phase)? - ANSWER Are movements that can happen at the same
time because do not conflict, or said differently, they do not ( collide) with one another.
Example of a (concurrent phase) - ANSWER A Thru movement and a adjacent left turn
movement can move on the same time.
What is a (sequential phase)? - ANSWER Cannot happen at the same time because they
conflict, or said differently, they (collide) with one another
In a " sequential phases ? How many movements can it have? - ANSWER Only one phase
