Traffic Engineering Investigation and Design

At Traffic Planning Consultants, our traffic engineering services are built around practical innovation — delivering solutions that enable growth, safety, and efficiency for developments of every scale. Whether you're planning a new subdivision, redeveloping a transport corridor, or delivering critical infrastructure, our team provides comprehensive, evidence-based traffic engineering advice to support project success.

Our experience spans road engineering for capacity upgrades, intersection and corridor design, and road safety improvements to reduce crash risk. We help clients identify where investment in infrastructure delivers the most value — and how to align design decisions with long-term land use and transport planning.

We support projects through:

Traffic flow analysis and performance modelling
Intersection design and optimisation
Corridor design and route protection
Temporary traffic management planning
Compliance with Austroads, NZTA, and Council design standards

Our role doesn’t stop at the drawings — we work closely with planners, architects, and local authorities to deliver designs that work for the community, meet regulatory expectations, and align with broader transport strategies. Whether you're delivering a town centre upgrade or navigating constraints on a compact residential site, we offer tailored solutions that move your project forward.

As one of New Zealand’s longest-serving traffic engineering consultancies, we’ve contributed to landmark developments across the country — including Fort Street Shared Space, Millennium Institute of Sport and the Lunn Avenue corridor upgrade.

Frequently Asked Questions

What does a traffic engineer do, and how do they support development projects?

A traffic engineer focuses on the safe and efficient movement of vehicles, cyclists, and pedestrians within a transport network. They support development projects by assessing access, parking, and intersection performance, and by providing traffic engineering solutions that improve overall functionality. As experienced traffic engineering consultants, we prepare detailed traffic engineering reports to help clients across NZ demonstrate compliance, gain consent approvals, and design practical outcomes that keep people and goods moving efficiently.

When should I engage a traffic engineer during the planning or design process?

It is best to involve a traffic engineering consultant early in your project’s planning or concept design stage. Early engagement helps identify access issues, road safety risks, and transport constraints before they cause delays or redesigns. Our team provides professional advice on traffic engineering and management, ensuring that every transport consideration is addressed and that your development complies with council and regional standards anywhere in NZ.

What is included in a typical traffic engineering assessment?

A traffic engineering report typically includes trip generation data, intersection capacity analysis, parking design review, and safety evaluation. It assesses how your project interacts with the surrounding transport network and recommends appropriate mitigation measures. By using proven traffic engineering solutions, we ensure your project operates safely and efficiently, aligning with best practice across leading traffic engineering companies in New Zealand.

How do traffic engineers evaluate road safety and intersection performance?

Traffic engineering consultants evaluate road safety and intersection performance through detailed on-site assessments, traffic modelling, and analysis of crash history. This information is compiled in a comprehensive traffic engineering report, identifying where improvements can be made. Our approach combines practical design thinking with data-driven traffic engineering and management principles to enhance road safety, reduce congestion, and support sustainable growth.

What are the most common transport issues identified through traffic engineering?

Common issues include inadequate access design, limited sight distance, high traffic volumes, and inefficient intersection layouts. These problems can affect both safety and network performance. Through targeted traffic engineering solutions, we identify the root causes and develop cost-effective strategies to address them. Our expertise as trusted traffic engineering consultants ensures that your project meets regulatory expectations while enhancing travel efficiency.
