Journal of Transport Geography (JTRG)’s scientific production has grown apace in line with the publication trend in general elsewhere, with many researchers of which more or less directly related to geography, who submitting their works to JTRG. Through an investigation of port articles published in JTRG (Group A) and other selected journals categorized into geography journals (Group B), and transport but non-geography journals (Group C) between 2009 and 2018, we strive to answer whether JTRG is more a transport or a geography journal given its double-sided nature. Using a well-defined analytical framework, we analyzed no less than 864 port articles that were categorized in terms of their spatial coverage from global to local, as well as their functional approach in terms of locational, operational, and socio-economic impact nature. Main results reveal that JTRG has a distinct ‘from top to bottom’ stable pattern with a preference for global level and operational research. Yet, in relative terms, JTRG remains specialized in regional/national spatial scales and in the spatial (locational) perspective. Such a research contributes to a better understanding of the disciplinary evolution of academic research in the field of spatial studies, transport studies, and beyond.
