Join us for the 11th biennial ICOET conference that will be held in September 2021. The conference will be concentrated in two periods between September 22nd and 30th, 1) between the 22nd and 23rd and 2) between the 28th through 30th.   ICOET is the foremost interdisciplinary, inter-agency supported conference addressing the broad range of ecological issues related to transportation systems in all modes. The conference is organized by the Road Ecology Center (UC Davis), with collaboration from the UC Davis Institute of Transportation Studies and the National Center for Sustainable Transportation at UC Davis

The 2021 conference will be special in two ways: 1) it will be entirely virtual and 2) without a geographic home, the 2021 conference will be hosted by the ICOET Steering Committee. The Steering Committee is comprised of agency, academic, consultant, and NGO scientists, practitioners, and policy-makers from North America and around the world. The virtual setting is both necessary because of the COVID-19 pandemic and reflects a growing movement in scientific conferences going online as a measure and reduce carbon footprint associated with in-person conferencing. That being said, as we are excited by the opportunities and rising to the challenges presented by a fully virtual format, we absolutely look forward to seeing you in person in 2023, as we embark on a hybrid ICOET conference model for the future.

This conference, ICOET will also host the first-ever "Global Congress on Linear Infrastructure and the Environment," which will be held the two days preceding ICOET (September 20-21) and bring together decision-makers, scientists and technical experts from around the globe to discuss the pressing issues associated with developing more sustainable linear infrastructure systems.
