In a planning phase

TRIEKOL (TRansportInfrastrukturEKOLogi) is the Swedish Transport Administration’s research program on the impact of transport infrastructure on biodiversity and landscape ecology. The aim of the research programme is to develop knowledge and methods that can help the transport sector to maintain, and where possible improve, the ecological functions and qualities of the landscape. The individual projects are linked to ongoing activities at the Swedish Transport Administration and their results are applied in the planning of new road and rail projects, in guidelines and in ongoing operation and maintenance.

During the year 2016, TRIEKOL is in a planning phase for the coming programme period 2017-2021. More information will be launched further on here on the website. To see the results from TRIEKOL during 2009-2015, see Earlier work and Publications.
