Council's told you a TGS traffic document is needed before your permit gets approved, and now your crew's schedule is hanging on a piece of paperwork nobody explained properly. It's one of the more common ways a project stalls - not because the work itself is complicated, but because a TGS traffic guidance scheme wasn't sorted early enough. Here's what one actually is, when you need one, and how to stop it from being the thing that holds everything else up.

What is a Traffic Guidance Scheme?

A Traffic Guidance Scheme is a scaled technical drawing showing exactly how temporary traffic control devices - signs, cones, barriers, delineators, arrow boards - get positioned around a worksite or road event. It maps out the advance warning area, the transition zone, the activity area, and the termination area, all defined under the Austroads Guide to Temporary Traffic Management (AGTTM). A TGS isn't a safety plan or a risk assessment written in prose - it's the precise drawing a traffic controller or site supervisor actually works from to set devices up correctly on the ground.

Why a TGS matters more than most contractors think

Get the TGS wrong - or skip it - and the consequences aren't abstract. A non-compliant scheme can see a permit rejected outright, work stopped mid-job once an inspector shows up, or genuine liability exposure if something goes wrong on site and the paperwork doesn't hold up. Road authorities, councils, and WorkSafe bodies across every state treat AGTTM compliance as a condition of approval, not a nice-to-have.

When is a TGS legally required?

Any work carried out on or next to a public road that affects traffic movement generally triggers the requirement - utility and infrastructure works (water, gas, electrical, NBN), road maintenance, events needing road closures or diversions, construction in or near a road reserve, and anything involving a lane, shoulder, or footpath closure. The exact trigger shifts by road type, speed zone, and jurisdiction, but as a rule of thumb: work in a 60 km/h zone or above almost always needs a formal TGS prepared by a qualified person. Lower-speed roads can still require one depending on what the local road authority wants.

TGS vs Traffic Management Plan - what's actually different

These two get used interchangeably by people who've never had to submit either, and that mix-up causes real delays. A TGS is the physical layout - where the devices actually go. A Traffic Management Plan is the broader document sitting around it: risk assessment, stakeholder notifications, emergency procedures, and a description of the work itself. Small jobs might only need a TGS. Bigger or higher-risk projects usually need both, with the TGS attached to the TMP rather than standing alone.

AGTTM compliance, explained plainly

AGTTM sets the national framework for managing traffic around worksites - device placement distances, speed-zone requirements, and documentation standards all sit inside it. "AGTTM-compliant" means a TGS follows those specifications properly, not just loosely. Each state layers its own requirements on top: Victoria's Department of Transport and Planning follows AGTTM Part 3, with pre-approved suppliers sometimes required on arterial roads; Tasmania's Department of State Growth applies AGTTM with state-specific supplements; South Australia's DPTI adds extra device spacing for high-speed rural roads; and the NT's Department of Infrastructure, Planning and Logistics often requires additional risk components for remote road works.

What a compliant TGS actually contains

Common projects that require a TGS

Common mistakes contractors make preparing a TGS

The recurring one is leaving it too late - treating the TGS as a formality to sort once everything else is locked in, then discovering council won't move the permit without it. Close behind is underestimating advance warning distances for the actual operating speed, rather than the posted limit, which is a fast way to get a scheme bounced back. Some contractors also try to reuse a TGS from a previous, similar-looking job without adjusting it for the new site's geometry, speed zone, or pedestrian conditions - a shortcut that rarely survives a council review.

DIY planning vs a professional TGS service

Who's actually allowed to prepare a TGS

This isn't a document anyone with good intentions can sketch up. Preparing a TGS requires the appropriate traffic management qualification - at minimum, completion of the Prepare a Worksite Traffic Management Plan unit (RIIWHS302E or equivalent). Higher-risk or more complex sites can call for a more senior qualification again. It's worth checking this before a scheme gets submitted, because council review will catch it if it wasn't.

Information you'll need before requesting a Traffic Guidance Scheme

☐  Site address or GPS coordinates

☐  Road name and number

☐  Description of the works being carried out

☐  Expected duration and work hours

☐  Speed zone for the site

☐  Photos or a rough sketch of the work area, for complex sites

How to choose the right TGS provider

Turnaround time matters, but it's not the whole story - a fast scheme that gets rejected at council doesn't actually save anyone time. Worth checking before you commit: does the provider operate independently from traffic control crews, or do they have an incentive to pad out the scope? Do they charge for amendments, or is revision included when council comes back with a query? And are the planners actually qualified, with real jurisdiction-specific experience across the states you're working in, rather than a generic template reused nationally?

Why contractors choose OnPoint TGS

OnPoint TGS prepares AGTTM-compliant Traffic Guidance Schemes across Victoria, Tasmania, South Australia and the Northern Territory, with a standard 4-hour turnaround once the required site information is in hand - same-day preparation is available for urgent jobs. Every scheme is prepared by senior planners with 20+ years of industry experience, and amendments are included at no extra cost if council comes back with changes. OnPoint operates independently - not owned by, or tied to, a traffic control company - so the planning stays focused on what's genuinely required for safety and compliance rather than an inflated scope that pads someone else's invoice.

From TGS to permits, handled end to end

If a client needs a Traffic Guidance Scheme prepared, that's covered. If council permits need managing and nobody wants to chase that process manually, OnPoint handles the application too. If traffic control contractors are required on site, OnPoint can engage and book trusted crews on the client's behalf - one point of contact instead of three separate suppliers to coordinate. Requests can be lodged directly through the Request a Plan page, or by getting in touch with the OnPoint TGS team directly.

Frequently asked questions

What is a TGS traffic guidance scheme used for?

It shows exactly how temporary traffic control devices are laid out around a worksite or road event - signage, barriers, cones, and staging - so a traffic controller can set the site up correctly and council can approve the permit.

Is a TGS the same as a traffic control plan?

In practice, the terms are often used to mean the same document. A TGS is the formal AGTTM-compliant version of a traffic control plan required for permit approval on public roads.

Do I need a TGS for a small job?

Often, yes. Even short-duration works affecting a lane, shoulder, or footpath can trigger the requirement - it's not limited to large-scale construction.

How fast can a TGS be prepared?

A standard TGS can be prepared in as little as 2 to 4 hours by an experienced planner, depending on site complexity. OnPoint TGS guarantees a 4-hour turnaround on standard jobs, with same-day options for urgent requests.

What happens if my TGS isn't AGTTM compliant?

Council or the road authority can reject the permit outright, or work can be stopped once identified on site. In a worst case, non-compliance creates liability exposure if an incident occurs.

Who can legally prepare a Traffic Guidance Scheme?

A person holding the appropriate qualification - at minimum the Prepare a Worksite Traffic Management Plan unit (RIIWHS302E or equivalent), with higher qualifications required for complex or high-risk sites.

Does a TGS cover pedestrian safety?

Yes. A complete scheme includes footpath closures, pedestrian detours, and safe access provisions where relevant to the site.

Can one TGS be reused across different sites?

Not reliably. Road geometry, speed zones, and site conditions vary enough between locations that a scheme built for one site rarely holds up as compliant for another.

What information does a TGS provider need from me?

Typically the site address or GPS coordinates, road name and number, a description of the works, expected duration and hours, and the speed zone - photos or a sketch help for more complex sites.

Are amendments included if council requests changes?

With OnPoint TGS, yes - amendments are included at no additional cost as part of the standard service.
