Professor Sieg has been elected Chairman of the Board of Academic Advisers to the Federal Minister of Digital and Transport since January 1, 2024. 

Prof. Sieg's term of office includes not only the 75th anniversary of the Advisory Board but also the greatest challenges for transport policy since the Federal Republic of Germany was founded:
"The transport sector is facing major challenges: Climate neutrality, affordability, poverty, demographics, to name but a few. Transport science can make a contribution to solving these problems. The Board works at the interface between science and policy advice and, as in the last 75 years, will continue to develop practical solution recommendations for the most important problems in transport. I am already looking forward to the coming years and the intensive communication and discussion with the Minister and the Ministry."
