phaseMinimumGreen OBJECT-TYPE
SYNTAX INTEGER (0..255)
ACCESS read-write
STATUS optional
DESCRIPTION " Phase Minimum Green Parameter in seconds (NEMA
TS 2 range: 1-255 sec). The first timed portion of the Green interval
which may be set in consideration of the storage of vehicles between the
zone of detection for the approach vehicle detector(s) and the stop
line.

phaseAddedInitial OBJECT-TYPE
SYNTAX INTEGER (0..255)
ACCESS read-write
STATUS optional
DESCRIPTION " Phase Added Initial Parameter in tenths of
seconds (0-25.5 sec). Added Initial parameter (Seconds / Actuation)
shall determine the time by which the variable initial time period will
be increased from zero with each vehicle actuation received during the
associated phase Yellow and Red intervals.

PARAMETER
phaseMaximumInitial OBJECT-TYPE
SYNTAX INTEGER (0..255)
ACCESS read-write
STATUS optional
DESCRIPTION " Phase Maximum Initial Parameter in seconds
(0-255 sec). The maximum value of the variable initial timing period.
Variable Initial timing shall equal the lesser of [added initial
(seconds / actuation) * number of actuations] or [ Max Initial ]. The
variable initial time shall not be less than Minimum Green.

[MIN GRN] Minimum Green (initial green). The shortest possible vehicle
green time, before any added initial or vehicle extensions. NOTE: Actual
minimum green indication will be the longest of the minimum green plus
any added initial, vehicle extension, bike minimum green, ped walk plus
ped clearance, or guaranteed minimum green*.
[ACT B4] Actuations Before. Number of
actuations that must be received during the phase’s yellow and red
intervals before seconds per actuation time is added to initial green.
[SEC/ACT] Seconds per actuation (Added
Initial). Time by which the phase’s added initial time period is
increased from zero for each vehicle actuation received during the
phase’s yellow and red intervals that exceed the Actuations Before
limit. 0-25.5 sec.
[MAX INI] Maximum Added Initial.
Maximum time that added initial green can attain. The number of vehicle
actuations received during a phase’s yellow and red intervals multiplied
by the seconds per actuation time cannot exceed this time. |
