Question 1

What are the best open-access journals for Transportation?

Accepted Answer

Transportation Research Interdisciplinary Perspectives, Smart Cities, ISPRS International Journal of Geo-Information, Urban Science, PROMET - Traffic&Transportation lead this list, drawn from a 17,500-venue index. All 39 ranked venues are listed on this page; 8 are Scimago Q1, 1 Q2, 2 Q3 and 28 have no Scimago quartile. Journals are placed by two independent classifications, OpenAlex's and Scimago's, plus any documented corrections. A journal both place under Transportation ranks ahead, within its Scimago quartile, of one only OpenAlex places there — because Scimago does not cover it, files it as Multidisciplinary, or files it under a neighbouring subject or only under a broad “(miscellaneous)” category (which counts as agreement when Transportation is the journal's main OpenAlex subfield). 8 journals OpenAlex files under Transportation are left out because OpenAlex's main field for them and Scimago's categories both place them in another discipline. By Scimago quartile first (Q1 → Q4, then venues without one). Within a quartile, journals both sources place under Transportation come first, then venues whose main OpenAlex subfield is Transportation come before those that list it second or third, and ties go to OpenAlex cites/paper over a 2-year window. A venue whose main subfield is unrelated to Transportation — fewer than a quarter of the venues filed under that subfield (or fewer than five) are also filed under Transportation — is listed after all the others. Only open-access venues are included. Venues OpenAlex files only under its catch-all triple of Aerospace Engineering, Sociology and Political Science and Transportation are excluded: that triple is where it puts work it could not place. Cites/paper is a transparent citation rate, not a licensed Impact Factor, and journals flagged as predatory are excluded. For a match to your specific paper use the Journal Finder (15 credits; free account starts with 25).

Question 2

Do these rankings use Journal Impact Factor (JIF)?

Accepted Answer

No. We don't compute or license Clarivate's Journal Impact Factor. These rankings use the Scimago SJR quartile (Q1–Q4) and OpenAlex cites/paper over a 2-year window — both transparent, openly-sourced signals. For Transportation, the highest-ranked venues by this method include Transportation Research Interdisciplinary Perspectives, Smart Cities, ISPRS International Journal of Geo-Information.

Question 3

How do I find the best journal for my specific Transportation paper?

Accepted Answer

Paste your title and abstract into the Journal Finder — it returns a shortlist matched to your paper from the same index, with open-access status and predatory flags. A free account starts with 25 welcome credits; each run costs 15.
