The first 25 years of Transportation Research Part D: Transport and Environment

Transportation Research Part D, launched in 1996, has succeeded in its mission of becoming a key outlet for interdisciplinary and policy-relevant research on transport and the environment. Using a bibliographic analysis of 2,521 papers published in this journal from 1996 to 2020, we identify key topics, top contributors, the most productive universities, and the leading research trends within the field. Emissions and air quality, climate change, energy, electric vehicles, noise and the built environment (land use and travel behavior) are dominant topics since the journal's founding. The journal has had an impact on policy, especially regarding land use and travel behavior. Citation levels seem to mirror these impacts. Electric vehicle policy and environmental impacts of shipping and ports are recent topical areas with large citation counts. All these issues will continue to resonate providing rich opportunities for innovative manuscripts that analyze problems and provide solutions.
