Transport and Travel Planning
Tetra Tech provides multidisciplinary transport planning, assessment, modelling, and appraisal services that help clients manage development, enhance access, manage travel demand, promote sustainable and active travel, and deliver inclusive mobility.
With experience across key transport sectors, we provide integrated transport planning services that support development, regeneration, sustainable and active travel, and infrastructure investment. Our teams help deliver planning approvals by assessing traffic impacts and travel needs, preparing local area and strategic models to identify solutions that mitigate development effects. We design infrastructure improvements and promote sustainable mobility for people and goods. We work with public and private sector clients to create well-connected, inclusive travel solutions that reflect community needs, client objectives, and policy priorities.
From early feasibility through to delivery, our specialists offer comprehensive insights on accessibility, land constraints, travel demand (including passenger demand), traffic management, public transport, and behaviour change. Our data-led approach—underpinned by experience, expertise, robust modelling, and local knowledge—enables clients to deliver successful projects that advance a sustainable future.
