Traffic Control Adelaide — Licensed Controllers for Roadworks, Events & Emergencies

When roadworks are underway, a construction site is active, or a major event is closing Adelaide's streets, professional traffic control is what stands between an orderly, safe operation and a chaotic, dangerous one. The difference between good traffic control and bad traffic control is not always visible — until something goes wrong.
One Stop Traffic Solutions is a licensed traffic control company serving Adelaide and South Australia. We provide certified traffic controllers, compliant traffic management plans, and the full suite of traffic control equipment needed to keep workers, pedestrians, and road users safe — across construction sites, road maintenance operations, utility works, council events, and emergency situations.
Our team operates under DPTI Traffic Management for Works on Roads standards, AS 1742.3, and the Work Health and Safety Act 2012 (SA). Every traffic controller we deploy is fully licensed, regularly trained, and experienced in real-world Adelaide road environments — from quiet suburban streets to busy arterial corridors and high-speed highways.
If you are looking for a traffic control company in Adelaide that is available when you need it, gets compliance right the first time, and has the resources to scale with your project — call 0477 707 838 today.

What Is Traffic Control and Why Does It Matter in Adelaide?

Traffic control is the management of vehicle and pedestrian movement around temporary conditions — roadworks, construction sites, lane restrictions, events, and emergency incidents. In South Australia, any works that affect a public road require a compliant traffic control arrangement in place before works commence, managed by licensed traffic controllers operating under an approved traffic management plan.

The consequences of inadequate traffic control in Adelaide are severe. WorkSafe SA can issue stop-work orders and significant fines for non-compliant traffic management on active sites. Councils can cancel road occupancy permits. And in the most serious cases, workers, pedestrians, or road users can be seriously injured or killed — outcomes that proper, professional traffic control is specifically designed to prevent.

One Stop Traffic Solutions takes this responsibility seriously. Our traffic control services are designed not just to satisfy the minimum regulatory requirements, but to create genuinely safe conditions for everyone interacting with your site.

Traffic Control Planning & Traffic Management Plans

Every safe traffic control operation starts with a well-prepared plan. Our team develops site-specific traffic control plans and Temporary Traffic Management Plans (TMPs) for projects of every scale — from a single-lane road closure on a residential street to complex, multi-stage contraflow systems on arterial roads and highways. We handle all permit applications to Adelaide City Council, suburban councils, and DPTI, and prepare documentation that meets audit and WHS compliance requirements.

Our traffic management planning service covers vehicle and pedestrian flow analysis, signage layout, barrier placement, speed zone requirements, emergency access provisions, and daily operational instructions for on-site controllers — giving your project team a clear, actionable document and council a submission-ready TMP.

Stop/Slow Traffic Control

Stop/slow traffic control is the most widely used method for managing single-lane sections through active work zones across Adelaide. Our licensed stop/slow operators manage vehicle queues safely and efficiently — coordinating with machine operators, communicating clearly with approaching drivers, and maintaining safe passage through constrained sections without unnecessary delays.

All our stop/slow controllers hold current South Australian traffic controller licences and are trained in the specific demands of different road environments — residential streets, busy arterials, school zones, and construction corridors. We deploy controllers to match the specific risk profile and traffic volume of your site, ensuring the right level of control is in place at all times.

Lane Closures

Lane closures on Adelaide's road network — whether for road maintenance, utility works, construction, or emergency response — require precise planning and compliant execution to maintain safe traffic flow and satisfy DPTI and council permit conditions. One Stop Traffic Solutions manages single and multi-lane closures across metropolitan Adelaide and regional South Australia, deploying appropriate advance warning distances, taper configurations, barrier systems, and variable message signs (VMS boards) to guide approaching traffic safely through the changed road environment.

Our lane closure arrangements include detailed single lane closure traffic control plans formatted for council and DPTI submission, and are adaptable to changing site conditions as works progress.

Temporary Traffic Signals

Where stop/slow operators are insufficient — high traffic volumes, long closure lengths, or poor sight distances — temporary traffic signals provide automated, consistent traffic control that can operate continuously without controller fatigue. We install and operate temporary traffic lights across Adelaide, programming signal timings to match actual traffic volumes and adjusting them in response to changing conditions throughout the day.

Temporary signals are particularly effective for infrastructure site safety management on arterial roads where works are ongoing for extended periods and manual stop/slow operation would be impractical.

Detours and Diversions

When full or partial road closures require vehicles to be redirected from their normal route, well-planned and clearly signed detours are essential to maintaining traffic flow and preventing driver frustration and risk-taking behaviour. One Stop Traffic Solutions designs and implements detour and diversion routes across Adelaide, coordinating with council traffic engineers to select appropriate alternative routes, installing advance and directional signage at all decision points, and deploying controllers at critical junctions where additional guidance is needed.

We manage community communication around detours for council and government clients — ensuring that affected residents, businesses, and regular road users have advance notice of changed conditions wherever possible.

Emergency Traffic Control

Infrastructure emergencies — burst water mains, power outages, gas leaks, road surface failures — require immediate traffic control response, often at short notice and in challenging conditions. One Stop Traffic Solutions provides 24/7 emergency traffic control across Adelaide, with on-call controllers and equipment ready to mobilise rapidly when unplanned incidents create immediate road safety hazards.

Our emergency response team coordinates directly with SA Water, SA Power Networks, emergency services, and council officers — establishing safe work zones, managing road closures, and maintaining traffic flow around the incident site until permanent repairs are complete.

Pedestrian Traffic Management

Pedestrian management is a frequently underweighted element of traffic control planning — yet pedestrians near active work zones are among the most vulnerable road users, particularly in Adelaide's CBD, shopping strips, and school zones. One Stop Traffic Solutions designs and manages safe pedestrian pathways around construction zones, events, and work sites — including temporary footpath diversions, safe crossing point establishment, and controller-assisted pedestrian management at high-volume locations.

Our pedestrian safety approach ensures that foot traffic is accommodated safely without being simply pushed onto the road or through hazardous areas.

Signage and Traffic Control Devices

Clear, compliant, well-positioned signage is the foundation of every effective traffic control arrangement. We supply, install, and maintain a comprehensive range of traffic control devices for all project types — warning and regulatory signs, delineators, water-filled barriers, safety cones, portable VMS boards, and temporary traffic signals. All signage meets AS 1742 standards and is positioned and maintained throughout the project to ensure maximum visibility and driver compliance.

Night Traffic Control

Many road maintenance and construction operations in Adelaide are scheduled for overnight hours to minimise daytime disruption — but night works introduce additional visibility challenges that require specialised traffic control. Our team offers night traffic control services across Adelaide, deploying high-visibility equipment, appropriate lighting, retroreflective signage, and experienced controllers trained in after-dark site management. We provide reliable night traffic control that Adelaide businesses, councils, and contractors can depend on to deliver safe operations regardless of the hour.
