The article analyzes the transport potential of the Organization of Turkic States through the prism of the emerging system of regional connectivity, in which the “Central Asia–Azerbaijan” axis plays a key functional role. Particular attention is given to the Middle Corridor as the spatial framework of transport integration and to the role of Azerbaijan as a Caspian–Caucasus node ensuring the linkage between the Trans-Caspian and western directions of Eurasian logistics. The study examines the infrastructure parameters of the route, the significance of the Zangezur Corridor and the China–Kyrgyzstan–Uzbekistan railway, as well as the competition among the northern, Trans-Caspian, and southern transport routes. Special attention is given to the digitalization of transit, including the implementation of eTIR, e-CMR, and the development of digital data exchange platforms. This study demonstrates that the transport agenda of the OTS is evolving into a multi-level system of integration encompassing spatial, institutional, and digital-governance dimensions.
