Aims & Scope

Transportation Research Part D: Transport and Environment publishes original research and review articles on the environmental impacts of transportation, policy responses to those impacts, and their implications for the design, planning, and management of transportation systems. It covers all aspects of the interaction between transportation and the environment, from localized to global impacts. All impacts are considered, including impacts on travel behavior, air quality, ecosystems, global climate, public health, land use, economic development, and quality of life. The journal invites submissions of research papers on all modes of transportation. This includes maritime and air transportation as well as all modes of ground transportation. Papers dealing with sustainability and resilience of the transportation system and its infrastructure as well as the impacts of a changing climate on cities, regions, and networks are welcomed.
