Section 03 — Standards Library
Official jurisdictional guidance.
Every Australian state and territory adapts the national Austroads framework. Filter by jurisdiction or search across all references — offline copies are flagged where available.
Section 04 — Reference Guide
A practical field reference.
A built-in primer on how Australian temporary traffic management is structured — the hierarchy of authority, the anatomy of a worksite, the documents you'll be asked to produce, and the acronyms that appear on every site.
§ 04.1
Hierarchy of authority
Authority over temporary traffic management flows downwards in four tiers — each tier inherits the floor set above it, and each can lift the bar but never lower it.
TIER 01
Austroads (national)
Publishes the AGTTM — the foundation document all states adapt. Sets minimum benchmarks for risk management, sign placement, and worker protection.
TIER 02
State road authority
Each jurisdiction (TMR, TfNSW, VicRoads/DTP, MRWA, DIT, State Growth, NT DIPL, TCCS) issues its own supplements — these prevail over Austroads where they differ.
TIER 03
Local government
Councils may layer additional permit conditions for works on local roads — particularly around school zones, heritage precincts, and event corridors.
TIER 04
Site-specific TGS / TMP
The Traffic Guidance Scheme and Traffic Management Plan apply the above to a specific worksite — prepared by an accredited designer and approved before deployment.
§ 04.2
State authority directory
The agencies you'll deal with for permits, accreditation, and approvals — vary by jurisdiction.
QLD
Department of Transport & Main Roads
Publishes the Queensland Guide to Temporary Traffic Management (QGTTM) — the QLD adaptation of AGTTM.
NSW
Transport for NSW
Issues the Traffic Control at Work Sites Manual (TCAWS) — NSW's principal field reference.
VIC
Department of Transport & Planning
VicRoads supplements augment Austroads with Victoria-specific worksite requirements.
WA
Main Roads Western Australia
Maintains the WA Traffic Management for Works on Roads Code of Practice.
SA · TAS · NT · ACT
State / Territory authorities
DIT (SA), Department of State Growth (TAS), DIPL (NT), and TCCS (ACT) each issue their own permits and amendments.
§ 04.3
The anatomy of a worksite
Every compliant worksite — from a single-lane patch to a multi-kilometre corridor — is built from the same five zones, in the same order, in the direction of traffic.
ZONE 01
Advance warning
Sequential signs warn approaching drivers and progressively reduce the speed limit.
ZONE 02
Transition (taper)
Cones and channelling devices angle inward to merge or close lanes smoothly.
ZONE 03
Longitudinal buffer
An empty separation between the taper end and the activity — never used as work area.
ZONE 04
Activity area
Where work occurs. Must include a lateral buffer between the work and live traffic.
ZONE 05
Termination
END ROADWORK sign and gradual return to normal speed and lane configuration.
§ 04.4
Sign categories used at worksites
Australian temporary signage follows AS 1742.3 conventions. The three families below cover the vast majority of devices you'll see — supplemented by electronic VMS and barrier-mounted lights.
T-SERIES
Temporary warning
Black symbol on amber diamond. The "roadworks ahead" family — workers, surface, equipment.
R-SERIES
Regulatory
White face, red border. Speed limits, STOP, no entry — legally enforceable.
W-SERIES
Permanent warning
Black on yellow diamond. Curves, intersections, hazards — kept active during works.
G-SERIES
Guide / direction
Green on white. Detour routes, advisory directions, distance markers.
VMS
Variable message
LED-matrix display. Used for changing conditions and high-volume corridors.
DEVICES
Channelling
Cones, bollards, T-top tubes, barrier boards — guide vehicles through transitions.
§ 04.5
Roles & responsibilities
Specific titles vary by jurisdiction — the functions do not. Every worksite involves these layers of accountability.
| Role | Function | Typical accreditation |
|---|---|---|
Traffic ControllerTC |
On-site stop/slow operation at lane closures, intersections, and crossings. The most visible role on any TGS. | Statement of attainment per jurisdiction (e.g. RIIWHS205 unit). |
Traffic Management ImplementerTMI |
Installs, monitors, and removes the TGS in line with the approved drawing — the bridge between the designer and the road. | Implementer accreditation (varies — RIIBEF305 or state-specific). |
Traffic Management DesignerTMD |
Prepares the TGS or TMP. Selects sign sequences, taper geometry, buffer lengths, and risk controls for site conditions. | Designer-level accreditation; may require RPEQ or equivalent for high-risk works. |
Principal ContractorPC |
Holds the head WHS duty for the workplace. Ensures the TGS is approved, implemented, and inspected throughout works. | WHS Act duty-holder — no specific TTM ticket required. |
Project / road authority engineerRTW |
Reviews and authorises the TMP for works on the network. Verifies design suitability against the local supplement. | RPEQ/CPEng or jurisdiction-equivalent professional registration. |
§ 04.6
Hierarchy of control
Ranked strongest to weakest. Always work down the list — exhaust elimination before reaching for PPE.
Eliminate
Remove the hazard entirely — close the road, defer to night, redesign the works.
Strongest
Substitute
Replace with something less hazardous — switch to off-peak hours, lower-risk methods.
Strong
Engineer
Physical separation — concrete barriers, attenuators, shadow vehicles, longer buffers.
Medium
Administrative
Procedures, signage, training, SWMS — relies on people following rules.
Weak
PPE
High-vis, helmets, boots, eyewear. Last line of defence — never the only line.
Weakest
§ 04.7

§ 04.8
Common worksite configurations
Schematic only — not to scale and not a substitute for an approved TGS. Real geometry is governed by speed zone, lane width, and sight distance.
Single lane closure TGS-01
One direction, one lane reduced. Most common configuration — taper merges into the live lane.
Full closure with detour TGS-02
Both directions stopped. Detour signposted on alternate route — requires advance notification.
Lane shift TGS-03
Both directions shifted laterally to clear a centre work zone. Used for centre-median works.
Mobile worksite TGS-04
Slow-moving work convoy with truck-mounted attenuator (TMA). Used for line marking, sweeping.

§ 04.10
Frequently asked questions
Common questions from new starters and crew leaders. General guidance only — your jurisdiction's supplement and the approved TGS always prevail.
Q.01
Do I need a TGS for a 30-minute job on a quiet road?
+
Almost always, yes. Even short-duration works that affect the carriageway require a documented control measure. Some jurisdictions allow generic "low-impact" or "minor works" TGSs for very short jobs, but the obligation to plan, brief, and record doesn't disappear because the duration is short — the legal duty under WHS legislation still applies.
Q.02
What's the difference between a TGS and a TMP?
+
A TMP (Traffic Management Plan) is the strategic document — it covers the whole project, including stakeholder engagement, network impacts, and staging. A TGS (Traffic Guidance Scheme) is the tactical drawing — the specific layout for a single shift or worksite. A project usually has one TMP and many TGSs.
Q.03
Do worksite speed limits apply to emergency vehicles?
+
Authorised emergency vehicles responding to an incident under lights and sirens are generally exempt from the posted limit, but they remain bound by a duty to drive with due care for workers. They are not exempt from physical obstacles — the layout must still be passable. Notify your TC if emergency access is foreseeable.
Q.04
Who is legally responsible if a TGS fails?
+
Responsibility is shared and layered. The Principal Contractor holds the head WHS duty. The Designer is responsible for the TGS being fit for purpose. The Implementer is responsible for installing it as drawn. The Traffic Controller is responsible for their on-site actions. WHS regulators look at the whole chain — and at whether each duty-holder discharged their duty.
Q.05
How often must signs and devices be inspected?
+
At minimum, after deployment, after every shift change, after any incident, and at the intervals specified in the TGS — which for higher-risk sites can be every two hours. Many road authorities require documented inspections; have a sign-off sheet on site. Storms, vandalism, and impacts can disrupt a layout in seconds.
Q.06
Can I deviate from an approved TGS on the spot?
+
Only the Designer (or someone with equivalent authority) can change the layout. If site conditions don't match the TGS — sight distance is shorter than assumed, traffic is heavier, weather has changed — the right action is to stop, secure the site, and contact the Designer. Document the change and re-brief the crew before resuming.
Q.07
Why is a buffer zone always empty?
+
Because it's an error margin. The buffer absorbs late-merging vehicles, vehicles that overshoot the taper, and impact-attenuator deployment distance. Putting workers, materials, or plant in the buffer defeats its purpose. The buffer length is calculated from the speed zone — at 80 km/h it's substantially longer than at 40 km/h.
Q.08
Are temporary speed limits enforceable?
+
Yes — temporary regulatory speed signs (R-series, white face with red border) carry the full weight of the road rules and are routinely enforced. Drivers caught speeding through worksites face increased penalties in most jurisdictions. Advisory amber-on-black signs ("Recommended 40") are guidance, not regulatory.
§ 04.11
Speed-zone dimensions reference
Indicative geometry for standard lane-closure layouts. Real values come from the AGTTM dimension tables and your jurisdiction's supplement — these figures should orient a design conversation, not replace one.
| Speed zone | Sign spacing | Taper length (per lane) |
Longitudinal buffer | Lateral buffer | Min sight distance |
|---|---|---|---|---|---|
| 40 km/h | 40 m | 20 m | 30 m | 0.6 m | 50 m |
| 50 km/h | 50 m | 30 m | 40 m | 0.6 m | 65 m |
| 60 km/h | 60 m | 40 m | 50 m | 1.0 m | 85 m |
| 70 km/h | 80 m | 55 m | 65 m | 1.0 m | 110 m |
| 80 km/h | 100 m | 70 m | 85 m | 1.2 m | 140 m |
| 90 km/h | 120 m | 90 m | 110 m | 1.2 m | 170 m |
| 100 km/h | 150 m | 110 m | 140 m | 1.5 m | 205 m |
| 110 km/h | 180 m | 135 m | 170 m | 1.5 m | 250 m |
Note · Indicative values only
Actual dimensions depend on lane width, road class (urban / rural / motorway), grade, weather, sight distance, and vehicle mix. Always reference the table that applies in your jurisdiction. Designers should verify against the current AGTTM Part 3 and the relevant state supplement before issuing a TGS.
§ 04.12
Accreditation matrix
Which credentials apply to which roles, and where they're recognised. Specific unit codes evolve — confirm the current requirement with the issuing authority before booking training.

| First aid + LVRHLTAID011 / HLTAID009 | At least one per crew | At least one per crew | — | — | National |
Refresher cycles vary by jurisdiction — most state cards require renewal every 3 years. Some authorities require additional state-specific training (e.g. NSW yellow / blue / orange cards) in addition to the national unit of competency.
§ 04.13
Common incident patterns & control
Patterns that recur across Australian worksites — drawn from regulator briefings and operational debriefs. The control measure column is what experienced designers add to the next TGS after seeing the failure.
Severity · High
CASE 01
Vehicle intrusion into the work area
A driver fails to merge at the taper and continues straight into the closed lane, striking workers or plant.
Control
Use a TMA (truck-mounted attenuator) at the buffer zone for any speed zone above 60 km/h, regardless of duration.
Severity · High
CASE 02
Worker struck while collecting cones
During pack-down, a worker walks into live traffic to retrieve a cone. Pack-down is statistically as dangerous as setup.
Control
Reverse-direction removal — pack down against the flow, never with it. Use shadow vehicle protection.
Severity · Medium
CASE 03
Sign sequence not matching TGS
Crew installs signs out of order or skips a sign because of a tight start. Approach drivers receive contradictory information.
Control
Pre-stage signs in installation order on the truck. TC verifies sequence before traffic exposure.
Severity · Medium
CASE 04
Buffer zone occupied by stored materials
Delivered material is staged in the buffer because the activity area is congested. Defeats the buffer's purpose.
Control
Designate a separate laydown area outside the TGS. Brief crew that the buffer is permanently empty.
Severity · Medium
CASE 05
VMS message faulty or stale
Variable message sign continues displaying a message after conditions change, or shows incomplete text after partial failure.
Control
Visual VMS check during routine site inspections. Maintenance log on the unit. Battery / solar status verified daily.
Severity · Low
CASE 06
Driver complaints about delays
Public frustration with stop/slow operations — sometimes escalates to verbal abuse or near-miss with the controller.
Control
TC briefing on de-escalation. Body cams in some jurisdictions. Rotating TC every 2 hours reduces fatigue-driven friction.
§ 04.14
Worked example — designing a lane-closure TGS
A walkthrough of how a designer arrives at concrete numbers from a brief. The figures shown here come from §04.11 — in practice you'd verify against the current jurisdictional supplement.
The brief
- Works
- Stormwater pit replacement, single shift
- Location
- Suburban arterial, two lanes each way, no median
- Posted speed
- 60 km/h
- Lane affected
- Kerbside lane, one direction
- Duration
- 06:00 — 16:00 (single day)
- Constraints
- Bus stop within zone · pedestrian footpath active · no detour available
The reasoning
Establish the regulatory basis
60 km/h zone, suburban arterial, single-lane closure → Cat 3 in most jurisdictions. AGTTM Part 3 + state supplement apply.
§04.1
Apply the dimensions table
Sign spacing 60 m · taper 40 m · longitudinal buffer 50 m · lateral buffer 1.0 m · sight distance min 85 m.
§04.11
Run the hierarchy of control
Cannot eliminate (works essential). Cannot substitute (no overnight option). Engineer: TMA at buffer + concrete kerbside protection. Admin: SWMS, TC. PPE last.
§04.6
Address site-specific risks
Bus stop relocated 80 m upstream with operator notice. Pedestrian footpath kept open with hoarding. School pickup window (15:00–16:00) flagged for additional TC.
Document & submit
TGS drawing prepared (taper geometry to scale), TMP narrative covering staging, road authority RTW approval lodged ≥ 5 working days prior, council notified.
§04.5
Brief & deploy
Pre-start with crew, SWMS sign-off, install in order against traffic, verify spacing on first pass, monitor at 2-hour intervals, pack down against traffic flow.
§04.7
§ 04.15
Interactive sign sandbox
Drag and position temporary signs on the sample road layout to trial basic placement ideas.
Tip: click and drag any sign block to move it around the lane.
Standards do not replace judgement on the ground. They define the floor — the engineer or controller is still responsible for the ceiling.— Working principle, AGTTM
