Technical/analytical research

Transport systems and infrastructure are constantly changing, which requires us to better understand the effects of these changes on transport patterns and traffic safety. Such investigations may require a combination of literature reviews, field surveys, modelling, and data analysis.

We regularly carry out analytical and technical transport research for national agencies, local councils, and other clients, and regularly publish and present our findings to industry (including many award-winning papers).
