Abstract：[Background] The development of the low-altitude economy has become a firm national commitment and long-term strategic priority. Major countries and regions worldwide are closely monitoring policies and technological advances in this domain. Specific“ground + low-altitude”scenarios give rise to a series of novel research questions, drive related technological progress, and have spawned a new research area: land-air integrated transportation. [Objectives] Standing from the perspective of road transportation, this paper aims to inspire researchers—particularly those with a background in traffic and transportation engineering—to explore potential research directions within the field of land-air integrated transportation, thereby advancing both theoretical research and practical engineering applications. [Methods] In accordance with the logical progression of“fundamental concepts-research examples-challenge analysis”, this paper outlines and illustrates the research value and typical research directions of land-air integrated transportation seeing from the aspect of road transportation. The research challenges in this field are then discussed. [Results] With the booming of low-altitude economy, land-air integrated transportation remains an emerging research frontier whose scope and boundaries warrant further exploration. Several relatively well-defined research directions have already begun to crystallize, including: airspace structure delineation; plan planning for air-ground vehicles; planning and selecting the locations of take-off and landing facilities; collaborative management and operational optimization of air-ground traffic flows; safety and risk management for land-air transportation systems; and public acceptance of low-altitude operations. Concurrently, we identify key challenges for researchers in this field: distinguishing and addressing both common and domain-specific issues; identifying“real scenarios”and“real problems”; managing the“complexity explosion”inherent in integrated systems; and assessing the long-term impacts of public trust and environmental sustainability on low-altitude economic policies.
