Advance: a Sage preprints community allows researchers within the fields of humanities and social sciences to post their work online and free of charge. Researchers can submit to the main Advance portal, or to the transportRxiv portal.

A preprint is a version of a scholarly piece of research that precedes review and publication in a peer-reviewed journal and has been posted to an open-access online platform. Papers posted to Advance or transportRxiv should not be taken as an endorsement or validation by Sage or by the Transportation Research Board of the paper's conclusions, findings, or quality.
