4. 2. Traffic Control Signals
2.1LM Asset Reference Number
An “LM” asset reference number identifies each traffic control signal
installation. This number is shown in the lower right corner of the drawing
immediately to the right of the drawing number. The LM asset number must
also be shown on all other documents in a suitable location.
2.1.1New Assets
New assets will require that new “As Constructed” asset drawings are
produced. MRWA will organise the new LM asset number and allocate the
asset drawing numbers.
2.1.2Existing Assets
An existing asset will already have been assigned an “LM” asset number and
have existing (“A” electrical and “B” marking) asset drawings. These asset
drawings numbers must be maintained throughout the life of the asset and
should not be changed. This will allow changes to the site that occur over time
to be easily recorded in the amendments column of the drawing. It is therefore
the asset drawing/s (not the design drawings) that should be updated if an asset
is modified. However, design/construction drawings may be added as a
reference drawing within the Asset drawing.
Asset numbers must not be duplicated.
2.2Asset Reference Number and Drawing Layout
2.2.1Title Block and References
Traffic control signal asset drawings will have a title block layout that provides
a discrete (eg LM001) “LM” asset reference number in the lower right corner
of the drawing and immediately to the right of the MRWA drawing number.
The drawing set will generally include an “A” and a “B” drawing. The “A”
drawing will contain the electrical installation details whilst the “B” drawing
will contain the road marking and signage information.
2.2.2AutoCAD File Name
The AutoCAD file name format for each drawing will be LM###A.dwg and
LM###B.dwg where ### is the three digit asset reference number. Should
more than one drawing be required then the file name would be extended to
include the sheet number (ie LM###AS1.dwg, LM###AS2.dwg) were S1 and S2
are sheet 1 and 2 respectively.

5. 2.3LM “A” Electrical Drawing
2.3.1General
The LM “A” drawing contains details relating to all electrical infrastructure,
the site configuration and the Traffic (phase) Movement Diagram.
2.3.2Feature Matrix
The following table provides a quick reference to the features that need to be
shown on the A and B asset drawing. Comments and reference to example
drawings are provided within the table.

Scale 1:125 1:500 If updating an old 1:250 “A” or 1:250 “B”
drawing redraw to 1:125 or 1:500,
respectively. Choose a standard scale
of best fit if the site reasonably exceeds
the page. Use content break-match
lines where appropriate. If a 1:125 is to
large for a LM A drawing then use
1:250.

2.3.3Traffic Movement Diagram
A Traffic movement diagram shall be located in the lower left corner of the
LM ‘A’ drawing, detailing the phases with which the signals operate. Each
phase shall be labelled as A, B, C, etc., according to the programmed operation
of the signals. Alternative phases shall be labelled by addition of a number
behind the phase number (Alt B1 and Alt B2).
Signal group numbers shall be shown within each phase corresponding to the
controller outputs. The movement numbers shall be shown against lanterns in
the main body of the drawing.
2.3.4Disconnected Services
Over time intersections will undergo modifications. Some equipment may be
disconnected (eg vehicle detection loops) or become redundant (eg where the
pits cable routes get moved). To avoid the asset drawing becoming cluttered
with obsolete information it is desirable not to show disconnected services.
However, where conduits or equipment are installed for future modifications
then a suitable note should be added to the body of the drawing. Otherwise
disconnected services should not be shown.
MAIN ROADS WESTERN AUSTRALIA ASSET DRAWINGS GUIDELINES – SECTION 2 – TRAFFIC CONTROL SIGNALS Page 6 of 25

7. 2.3.5Underground Post to Pit Connection Table
Signal poles will either be wired as a ring main or pit system. If the site has a
pit system installed then the asset drawing must contain a pit to pole
connections table similar to the following:
Pit/Controller Post

Starting in an anti-clockwise direction from the northern most loop on the
Western leg of the intersection, the loops (except Red Camera loops) should be
allocated a loop number designated by L1 for the first loop, L2 for the second
loop etc, until all loops are numbered in keeping with the programmed loop
allocations. A diagram detailing the loop feeder cable route is also required to
be detailed on the drawing.
(A layout of the detector loop arrangement and connection to the loop pits is
indicated on Drawing 9748-1114).
2.3.9Pedestrian Detection
Pedestrian push buttons shall be shown and marked with a PB number that will
be paired with one on the opposite kerb side. Symbols for standard (non audio)
and audio-tactile push buttons should match those shown on the standard
symbols drawing.
2.3.10Illuminated Flashing No Right Turn Signals
Illuminated flashing NO RIGHT TURN signals shall be shown. A minimum
of two signals shall be displayed for each direction of travel and attached to the
dual primary and the secondary signal posts.
2.3.11Rail Crossing

22. FIRST ST/SECOND ST ADVANCED WARNING FLASHERS
LM : ###
DATE :
INTERSECTION : First St./Second St.
FLASHERS
SGP7 and SGP8 flashing AMBER/GREEN is at a rate of 1Hz (ie 0.5 sec ON/OFF) during
EARLY CUT OFF GREEN of :
"A” PHASE (ie SGP7 for SOUTH BOUND on Mandurah Rd) while SGP1 is RED or
"A & C” PHASES (ie SGP8 for NORTH BOUND on Mandurah Rd). while SGP1 and/or
SGP4
are RED.
The "PREPARE TO STOP" SIGNS are located on the SOUTH BOUND and NORTH BOUND
approaches of MANDURAH RD.
The distance from the TRAFFIC SIGNALS STOP LINE and the EARLY CUT OFF TIME are
shown below:
Calculation of ECO AMBER for FLASHERS.
SOUTH BOUND and NORTH BOUND SGP7/SGP8
EARLY CUT OFF TIME = (D(m) + 21.3)/V(m/s)
D = DISTANCE from STOP LINE to SIGN, with NEGLIGIBLE GRADIENT and a posted
speed limit of 80 Km/h, giving a DISTANCE of 106 metres.
ECOG time (Early Cut Off Green).
V = VELOCITY = Speed limit/time. Posted Speed Limit is 80 Km/h.
V = 80x1000(m)/60x60(s)
V = 22.2 m/s
ECO = (106(m) + 21.3)/22.2(m/s)
ECO = 5.73(s) - Therefore ECO time rounded off to 5.8s.

23. DIAMOND FILTER NOTES
FIRST ST./SECOND ST. LM: ###
Additional notes for Single Diamond FILTER
This site operates to Single Diamond standard with the following exceptions:
• Filtering is always permitted on the A-B approach (signal group 3) during "A".
- The SGP3 Red arrow will be held red during:
. "A" phase late start interval following B, E, E1 and E2.
. The pedestrian 1 Walk period .
- The controller prevents local demands for "C" phase to inhibit the movement from "A" to "C", as the SGP2 is
not permitted to overlap from "A" to "C".
- Loop 3 places a demand for "E1" during "A" phase subject to the presence time on DET 3, to avoid a funny
shut down situation ("A" to "E1") the controller will go from "A" to "E" phase.
- Loop 3 extends "A" phase ( approach A3 ) until the presence timer has timed off.
• Filtering is always permitted on the A-C approach (signal group 4) during "A".
- The SGP4 Red arrow will be held red during:
. "A" phase late start interval following C, E, E1 and E2.
. The pedestrian 1 Walk period.
- The controller prevents local demands for "B" phase to inhibit the movement from "A" to "B", as the SGP1 is
not permitted to overlap from "A" to "B".
- Loop 9 places a demand for "E2" during "A" phase subject to the presence time on DET 9, to avoid a funny
shut down situation ("A" to "E2") the controller will go from "A" to "E" phase.
- Loop 9 extends "A" phase ( approach A4 ) until the presence timer has timed off.
Notes on SGP7 Left Turn:
Signal Group 7 is green during B,D,E & E1 Phases but overlap only permitted
from E - E1 phases. SGP7 closes down between phases B,D & E and remains Red at the start of those phases to permit
right turn filter traffic from the opposing lane (loop11).
Delayed start of SGP7 is subject to Special Timer 10.
