Ryden picked up the inaugural RTPI Award for Research Excellence by a Planning Consultancy at a ceremony in Cardiff yesterday.
Against a strong field of projects from across the UK, Ryden won with the Planning for Infrastructure Research Project, produced for the Scottish Government and Transport Scotland in 2015.
The judging panel was made up of UK academics and planners.
Accepting the award, Ryden's Dr Mark Robertston thanked Ryden colleagues and WSP and Brodies who worked on the project, and highlighted the importance of using research to inform policy making.
Bill Duguid, managing partner of Ryden stated: "We are thrilled that our work has been recognised by this highly competitive national award. It recognises the very high quality of Ryden's planning and research advice and shows that our advisers are among the very best in the UK."
