The dissertation is devoted to a comprehensive study of the material and conflict-of-law regulation of international mixed transportation in Ukraine and foreign countries, emphasizing the necessity and appropriateness of unifying the norms of international private law in this field. The dissertation clarifies the legal nature of international mixed transportation of goods, passengers, and luggage. The author demonstrates that international mixed transportation represents a multi-structured construct, and the term "mixed transportation of goods, passengers, and luggage" serves as a collective and generalizing term lexically and legally for multimodal, intermodal, and combined transport of both goods and passengers and luggage. The dissertation identifies the characteristics of international mixed transportation of goods, passengers, and luggage, specifically: 1) features of transport activities providing transportation services (transportation occurs based on a contract, formalized through the issuance of the relevant transport document); 2) characteristics inherent in international transportation (legal regulation based on international conventions and relevant bilateral agreements, with international transport law stipulating the limits of carrier liability, claims 6 procedures for dispute resolution, and shortened limitation periods); 3) characteristics specific to mixed transportation (the use of several modes of transport, a single transport document, and the presence of a person responsible for the safety of goods, luggage, and passengers throughout the transportation process (the mixed transport operator)). For passenger transportation by various modes of transport under a single document, the author suggests using the term "mixed transportation of passengers and luggage," with the single document defined as the "single ticket" and "single baggage receipt." The author introduces the concept of "multimodal digital transport corridor" into scientific discourse and defines it as an integrated transport infrastructure system for coordinating and optimising transportation by various modes of transport using modern information technologies: monitoring and tracking systems, real-time data processing, the use of the Internet of Things, data analytics and other innovative tools to improve the management and optimisation of logistics processes along the transport route, aimed at maintaining the efficiency, reliability and speed of transportation of goods, passengers and baggage. The dissertation enhances the scientific approach to understanding the foundations for the formation and implementation of state transport policy and prepares proposals for improving state transport policy through the introduction of a specialized service for the multimodal digital transport corridor, within which the "single window" principle will be realized. The work provides the author's interpretation of the definition of the "contract for international mixed transportation" as an agreement between the parties (the operator always acts as the executor, while the passenger or consignor acts as the client), under which the mixed transport operator, for a fee, commits to execute or ensure international mixed transportation by various modes of 7 transport from a point of departure in one state to a destination point in another under a single transport document. The dissertation delineates the essential conditions of the international mixed transportation contract into three groups: 1) essential conditions characteristic of all transportation contracts, 2) essential conditions characteristic of international contracts complicated by a foreign element, and 3) essential conditions that are unique to mixed transportation. The necessity for international unification of the legal regulation of international mixed transportation of goods, passengers, and luggage is substantiated through the development of a single international legal document in the field of international multimodal transportation and mixed passenger transportation. The author argues that the contract of international mixed (multimodal) transportation is inextricably linked to organisational agreements between transport companies, in particular, freight forwarding agreements and nodal agreements. The author identifies their interdependence: without entering into an organisational agreement, it is impossible to perform a multimodal transportation contract, and without it, in turn, there is no point in an organisational transportation contract. The dissertation argues that national legislation regarding the legal regulation of mixed transport operator liability requires improvement, suggesting the need to define "the limit of liability of the actual carrier" at the legislative level.
