Established by the UK government in 1933, for more than 80 years the Transport Research Laboratory (TRL) has orked with governments, international funding institutions and private sector clients to bring knowledge and nderstanding based on research and testing to a vast array of transport related issues. This has enabled us to set standards, formulate policy, manage risk, improve safety, reduce environmental impacts and encourage good engineering practice. TRL was moved to the private sector in 1996 and today we have clients in 145 countries and completed over 800 projects in 2013. The TRL of today is internationally recognised as a centre of excellence, providing research, consultancy, advice and solutions across a broad range of current transport issues that reflect the needs of our public and private sector clients. Commercially independent, with a vast compendium of knowledge and experience embedded in our history, we continue to provide leading edge expertise, supported by a range of first class test facilities.
