Traffic Management Plan Implementation SWMS
Implementation of traffic management plans on public roads — setting up exclusion zones, delineation, speed reductions, and worker protection during roadworks.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Traffic Management Plan (TMP) implementation involves the physical deployment of temporary traffic control devices on public roads, including the setup of exclusion zones, lane closures, speed zone reductions, advance warning signage, and the establishment of worker safety zones during roadworks, utility works, and construction activities. This work routinely exposes traffic controllers, sign crews, and Traffic Management Implementers (TMIs) to live traffic at speeds up to 100 km/h, making it one of the highest-risk activities in the construction sector. Under WHS Regulation 2025, any work conducted on or adjacent to a road where there is a risk of being struck by a moving vehicle constitutes High-Risk Construction Work (HRCW) under Schedule 1, requiring a documented Safe Work Method Statement before any worker steps onto the carriageway. This SWMS aligns with the Austroads Guide to Temporary Traffic Management (AGTTM) and AS 1742.3:2019, providing PCBUs and principal contractors with a defensible compliance record that demonstrates the hierarchy of control has been applied and that workers have been consulted, trained, and signed on prior to deployment.
Hazards identified
7 hazards covered, sorted by priority.
Fatal blunt force trauma, multi-system injury, polytrauma; PCBU industrial manslaughter exposure under WHS Act
Severe lower-limb fractures, traumatic head injury, death from secondary vehicle impact
Multiple worker fatalities, plant damage, prosecution for inadequate physical separation under AGTTM
Rear-end collisions, queue-end shunts, secondary crashes into workers and plant
Heat exhaustion, heat stroke, dehydration leading to loss of situational awareness and chronic skin damage
Vehicle strike, failure to detect taper transitions, increased collision severity under low-light conditions
Lumbar strain, rotator cuff injury, hernias, cumulative musculoskeletal disorders requiring workers compensation
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Where feasible, eliminate worker exposure by conducting works under full road closure with detour, removing live traffic interaction entirely from the work zone.
- 2Elimination — Schedule non-urgent works to off-peak or night windows on high-volume roads to remove peak-hour traffic volumes from the worksite environment.
- 3Substitution — Substitute manual traffic control (stop/slow bat) with portable traffic signals or Boom Gate Arrest Systems on roads exceeding 80 km/h posted speed.
- 4Engineering — Deploy Truck-Mounted Attenuators (TMAs) and Mobile Variable Message Signs (VMS) to absorb errant vehicle impact and provide advance driver warning per AGTTM.
- 5Engineering — Establish physical separation using water-filled barriers, concrete barriers, or steel guardrail between live traffic lane and worker zone where speeds exceed 60 km/h.
- 6Engineering — Apply lateral safety buffer and longitudinal taper lengths calculated per AS 1742.3:2019 Tables, sized to posted speed and lane width.
- 7Administrative — Conduct documented pre-start briefing using this SWMS, confirm TMI/TC accreditation currency, and assign a dedicated Safety Observer for all workers on foot.
- 8Administrative — Enforce no-lone-worker rule, two-way radio communication, designated escape routes, and rotating crews to manage fatigue on shifts exceeding 8 hours.
- 9Administrative — Conduct daily TMP audits against deployed layout, photograph compliance, and log any driver incursions or near-misses for review.
- 10PPE — Issue and enforce Class D/N AS/NZS 4602.1 compliant hi-vis garments, safety footwear, hard hats, hearing protection in proximity to plant, and SPF 50+ sunscreen for daytime works.
Applicable Codes of Practice
Mandates a SWMS be prepared, available on site, and complied with before any work in the vicinity of traffic begins under HRCW Cat. 17.
Prescribes signage spacing, taper lengths, buffer zones, and device selection — referenced as the deemed-to-comply standard for TMP design and implementation.
Specifies TMI/TC competency, risk assessment methodology, layout selection, and minimum worker protection standards adopted by state road authorities nationally.
Establishes general construction duties, SWMS content requirements, consultation obligations, and the hierarchy of control framework applied throughout this document.
High-Risk Construction Work triggered
Implementation occurs directly on live carriageways with vehicles travelling adjacent to workers, meeting the Schedule 1 criterion for vicinity-of-traffic high-risk construction work.
PCBU must prepare the SWMS, consult workers, retain records for the duration of the work plus any notifiable incident period; penalties under WHS Act are substantial and indexed, with current maximums following the prevailing WHS schedule.
Who this is for

Worked example
On a regional arterial road resurfacing project, a Traffic Management Implementer arrives at 4:30am for a night-shift lane closure on an 80 km/h carriageway. At the pre-start brief held at the depot lay-down area, the crew supervisor opens this SWMS on a tablet and walks the four-person crew through the hazard register, focusing on errant vehicle intrusion and sign-deployment strike risk given recent rainfall and reduced pavement friction. The supervisor confirms each worker holds current TMI accreditation, reviews the AS 1742.3 taper layout for the posted speed, and assigns roles: two sign-crew, one TMA driver, one Safety Observer. Each worker signs the SWMS sign-on register electronically. During deployment, the Safety Observer notes a heavy vehicle failing to slow at the advance warning sign and radios the crew to retreat behind the water-filled barrier. The supervisor pauses the task, returns to the SWMS, and adds an additional engineering control — bringing forward a second VMS board 200m upstream — documenting the change as a dynamic risk adjustment. The amended SWMS is re-briefed, re-signed, and work resumes. At shift end, the document is filed with photographs of the deployed layout, the sign-on sheet, and the incursion log, forming the defensible compliance record required under WHS Regulation 2025.
