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
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
,2|Page
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
The yellow-red flashing mode provides the same type of
control 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
