TRAFFIC AND TRANSPORT ENGINEERING
We turn traffic data into informed design decisions. From impact assessments to road access, we connect developments to cities and highways.

FEATURED PROJECT · ATIBAIA, BRAZIL
01 / WHAT WE DO
Every development needs its own response. We combine field surveys, operational analysis and design to inform decisions at every stage.
Understand the impacts of your development and its operational needs.
Traffic impact reports; demand, capacity and level-of-service analysis; parking and circulation assessments; technical support for authority and concessionaire reviews.
Tell us about your projectConnect developments to road infrastructure.
Functional, geometric, preliminary and detailed access and intersection design. Coordination of earthworks, pavement, drainage and signage disciplines as required by the agreed scope.
Tell us about your projectBuild a sound evidence base for your project.
Classified traffic counts, origin–destination surveys and field observations. Data preparation and interpretation to support traffic assessments.
Tell us about your projectCompare scenarios before making decisions.
Network, intersection, queue and capacity analysis. Traffic modelling and simulation to assess operations and compare intervention options.
