We hold 20+ years of long-term partnerships with both public and private institutions, offering an integrated suite of traffic and transport engineering services.

Our traffic team has a proven track record in providing engineering studies and investigations for hospitals, educational facilities, public institutions, shopping centres, residential developments, town centres, transport hubs, and industrial sites.

No matter the project size, type, or complexity, our engineers focus on delivering high-quality advice and sound solutions. We bring creativity and innovation to your project from planning through to design and implementation.

We deliver an integrated suite of traffic and transport engineering services; audits, planning and management, modelling, transport infrastructure and transport economics.


Traffic Impact Assessments (TIA)

TTW provides thorough documentation and reporting to accompany development applications and satisfy authority requirements.

We have extensive experience in preparing the reporting and documentation that provides the approval authority with all the information and analysis to consider the project favourably.

Projects range from individual residential housing at local council level, through to State Significant Development Applications for hospitals and schools.

Intersection Modelling

Inefficient and poorly-planned intersection configurations frustrate both authorities and roads users. Our engineers utilise SIDRA (intersection modelling software) to identify issues before they occur, or to resolve existing problems on the road network.

Our methodology compares and reviews alternative treatments (including signals, roundabouts, and give way/ stop controls) for single intersections or local networks, advising the optimal solution to reduce congestion and improve traffic flow.

Road Safety Audits

At any stage in a project from concept to completion, our qualified road safety auditors provide expert insights to
minimise risk and provide a safer environment for the end user.

Our road safety audits can identify issues related to sight distance, road geometry, lighting, and pedestrian-vehicular conflicts.

Design Advice

During the design process, our engineers can assist in the development of car parks, loading docks and access points
to improve and optimise the design.

Detailed vehicle analysis ensures that swept paths and vertical geometries are not only compliant but tailored to serve the users of the site.

Construction Traffic Management Plans

Our expert engineers work closely with clients to develop plans for managing traffic and mitigating disruption during on site works, with an aim to minimise risk, delays, and inconvenience to users.

We investigate all elements of the construction process including site access controls, construction vehicle management, and local traffic impacts.

Our team will develop a specific Construction Traffic Management Plan (CTMP) that meets local government requirements and assists the builder with demolition plans and construction. Traffic Control Plans (TCP) can be prepared when required.

Sustainable Transport Plans

As our cities are becoming more congested, therefore, transport strategies can assist in reducing car volumes. Public transport, walking, and cycling are often a good alternative for users while providing health and congestion benefits.

Our TTW Traffic team can provide a variety of purpose-built planning and operational documents, including Green Travel Plans and Transport Access Guides. We provide consultation with local authorities to gain access to improved services and infrastructure.
