The Gray Centre for Mobility and Activity

Note: The May 2025 reporting window reflects the timestamp in article metadata, not the month that research articles are featured in issues of The Mobility Brief. In other words, this report defines "May 2025 publications" by the most recent (latest) publication date that was available in the article metadata when the article was indexed. We adopt this standard to provide a consistent month-to-month reporting criteria, even though official publication timelines can be complex and defined sporadically across publishers. A single article can have multiple associated dates: from its initial preprint, to its formal acceptance after peer review, to its "online first" state, perhaps its "author approved" version in an institutional repository, and finally to its full, typeset inclusion in a journal issue as the final Version of Record (VoR). Depending on the circumstances and publisher timelines, these stages can be months apart and these kinds of date changes are not reflected in this report. By using the latest date at point-of-indexing, we aim provide a consistent and timely snapshot of published research. However, as a result, this list is not static and might be updated dynamically in the future when/if additional articles from May 2025 are identified.
