IMSA 1 Test with Correct Answers 100% Solved
Although most Signalized grade crossing are controlled by railroad flashing light signals with...
Correct Ans-Two circular red indications that flash in an alternating manner
Ramp metering signals. Correct Ans-The signals placed on the entrance of a ramp to a
roadway and usually have two sections: a circular green indication to allow a single vehicle to
proceed at a time and circular red indication to stop all approaching vehicles.
Other types of beacons include... Correct Ans-warning beacon (flashing circular yellow
indications) and stop beacons (flashing circular red indications)
Traffic signal phase Correct Ans-Phases are numbered 1 thru 8. Phase 2 and 6 are most
commonly assgined to major street trhough movement
Interval Correct Ans-Is the amount of time that a particular indication is given during a
phase
Rings Correct Ans-Each ring of a traffic signal controller is a series of conflicting phases that
occur in an established order but can never simultaneously with each other.

Barriers Correct Ans-Is a boundary point in the preferred sequence of a dual ring controller
that both rings must simultaneously cross because the phases on one side of the barrier are
for one street, and the phases on other side of the barrier are for the other street.
concurrent phases Correct Ans-Are movements that happen at the same time because
they do not conflict with one another.
The minimum green or initial green time Correct Ans-Is the absolute minimum time that
the green indication must be displayed.
Passage time and extension time Correct Ans-Making the time long enough for a vehicle
leaving the advance loop to get to a point where it will continue through the intersection if
the light turns yellow.
Which are the two Traffic Signal Level 3 Correct Ans-Bench
Electrical (Field)
Personal safety is a matter of Correct Ans-Regulation and common sense
