From the ITS America website:

ITS America 2021 will reimagine transportation and discuss how technology is a foundational piece of a new 21^st century transportation system. It will bring together the intelligent transportation community for four days of thought-provoking education, networking, technical tours and demonstrations exploring products, emerging technologies and solutions that will enable a better future transformed by intelligent mobility. In addition, the event will incorporate a hybrid/virtual access component, which will include live streaming of keynotes and selected sessions to ensure parts of the Annual Meeting are available “remote-live.”
