Rigorous traffic engineering is at the core of everything Okami Cho does. We combine deep technical expertise in intersection design and analysis with advanced traffic modelling to deliver solutions that are safe, efficient, and built to last.

Our intersection design capability covers the full spectrum, from roundabouts and signalised intersections to complex multi-leg and grade-separated arrangements. We are experienced in both SIDRA and LinSig intersection modelling to assess capacity, delay, and level of service, informing design decisions with confidence and precision. This analytical rigour has been applied across Traffic Signal Approvals, major corridor upgrades, planning studies, and intersection-specific investigations for Main Roads and local government clients throughout Western Australia.

Adam Reynolds is one of the few accredited Lead Operational Efficiency Auditors based in Perth, which applies an independent, and structured audit process to freeway infrastructure projects to verify that designs are fit for purpose and will operate safely and efficiently. Operational Efficiency Audits assess whether a freeway project meets the principles of smart freeway design, checking everything from ramp layout and storage capacity to ITS requirements and network connectivity. Adam has led and contributed to audits across many of WA’s most significant freeway projects, including the Roe Highway Upgrade, Tonkin Highway Grade Separations, Tonkin Highway Extension, and multiple Smart Freeways projects, bringing the same independent, evidence-based rigour to every review.
