I’m torn between asking for my (somewhat weighty) conference paper to be included in an issue of Transportation Research Procedia, versus submitting it separately to a journal with an impact factor, e.g., Transportation Research B. The conference paper will have to be peer reviewed to qualify, but the journal advice says,
The Transportation Research Procedia does not have, and is not eligible for, an Impact Factor as it does not publish primary research, full length, peer-reviewed articles.
Is a separate submission likely to be worth it (i) for dissemination of the research, and (ii) for REF (Research Excellence Framework) return?
