COMPLETE QUESTIONS AND VERIFIED ANSWERS
|ALREADY GRADED A+|
List 2 things that describe the vehicle movement made at an
intersection? - ANSWER-direction of approach
maneuver
In usual convention, how are through phases numbered? -
ANSWER-in a clockwise direction starting with phase 2
Some agencies refer to a combination of movements as a phase.
This is also true in some older controller assemblies that operate
with what maximum amount of phases? - ANSWER-4
When it comes to barriers for dual ring controllers there are
_______ barriers, one for leaving ________ street and one for
leaving ________ street - ANSWER-2, major, minor
, Page |2
Is this true about an independent overlaps: An independent
overlap follows a designated phase - ANSWER-no
Parent/child overlaps are the most common type of overlap. The
overlap is viewed as the ________ because it is only present
when one or more phase is active, which is referred to as the
______ - ANSWER-child, parent
This left turn phase is defined as "both modes occur on an
approach during the same cycle"? - ANSWER-
protected/permissive

as a 2 way stop control where only the minor streets have a
what? - ANSWER-stop sign
In order to ensure fail safe operation, what occurs when a conflict
monitor unit (CMU) detects a fault? - ANSWER-the flash transfer
relays have all of the signals display red

ANSWER-gap reduction
What are factors of gap reduction allowing for extension/passage
time to be reduced? - ANSWER-time to reduce
Passage time is a function of: - ANSWER-distance from the stop
line to the detector
