National DTC segments and development of digital corridor passports
Asian Development Bank Digital CAREC project
The previously described principles for building Digital Transport Corridors (DTCs) were applied during the implementation of the Asian Development Bank project TA6694 REG: Digital CAREC to develop recommendations for building national segments of multimodal digital corridors in several CAREC countries. Within this project, CompleteSoft specialists proposed a methodology for creating digital passports for national segments of transport corridors in CAREC countries. A digital passport of a transport corridor is a comprehensive set of information about the digital infrastructure elements of national DTC segments, including the IT systems and platforms used, communication facilities, technological solutions for processing and exchanging data and electronic documents used by transport process participants, as well as the list of provided digital services.

In general, a digital passport of a national transport corridor segment should contain the following parameters:

  • Scheme and geographical location of corridor nodes/terminals, including Border Crossing Points (BCPs);
  • Transport and communication connectivity with other nodes/terminals and BCPs;
  • Main cargo flows handled by each transport node and BCP;
  • Operator/operating company of the node or terminal;
  • IT systems, platforms, and technological solutions used;
  • Core technological process for cargo handling in the transport node or logistics center;
  • List of documents used: paper and electronic — and their role in the technological process;
  • List of digital/information services provided;
  • Modernization and digitalization plans.

Based on the information collected for the digital passport of a national transport corridor segment in a specific country, a digitalization scheme can be developed in accordance with the proposed DTC construction principles.
An example of such a scheme proposed by Completesoft experts for the national segment of the CASCA+2 transport corridor in Uzbekistan is shown in Figure 1.

The diagram shows all major elements of the digital infrastructure and their information interaction with the national electronic logistics platform (“E-logistika”) being developed in Uzbekistan. Such schemes can be effectively used to develop recommendations for information interaction among key elements and participants of the national DTC segment. In particular, data received from participants of the CASCA+ corridor in Uzbekistan, together with generated standardized electronic documents, should be stored in the main database of the “E-logistika” platform in order to provide access for authorized government authorities involved in monitoring transit processes in the country. Relevant government IT systems should be connected to the “E-logistika” platform, which — together with the electronic customs system and electronic licensing system — will become the third core system of the country’s integrated national Single Window for trade. Uzbekistan’s electronic customs system and its remote electronic declaration centers are used as the core modules for electronic customs procedures and information exchange between customs authorities of Central Asian countries within the CAREC region.

In addition, all IT systems of transport modalities in Uzbekistan, border crossing points (BCPs), and key transport hubs — Tashkent, Navoi, Bukhara, and Nukus/Kungrad — should be connected to the “E-logistika” platform through its integration layer. Data received from BCPs and other participants of the technological level of the DTC may be processed at the multimodal orchestration layer of the “E-logistika” platform to generate standardized international electronic documents used within the DTC data pipeline. Required service modules for generation and processing of e-SMGS, e-CMR, e-Airway Bill, and other electronic documents may be deployed either at the service layer of the “E-logistika” platform or within the IT systems of transport modalities.

Cross-border and other digital infrastructure elements of the CASCA+ corridor national module in Uzbekistan should be integrated into the DTC data pipeline and use corresponding DPM modules as information “entry” or “exit” points. Thus, a unified trusted information space can be established within the national segments of Uzbekistan’s major transport corridors. Data related to a specific transit cargo shipment, as well as all generated electronic documents and their amendments, may be stored in the core database of “E-logistika” and accessed through authorized and authenticated access mechanisms. As in other countries, such a functional approach helps preserve digital sovereignty and ensure data protection within Uzbekistan’s transport corridors. Integration and digital connectivity of national segments of the main international transport corridors passing through Uzbekistan — China–Kyrgyzstan–Uzbekistan, the Middle Corridor, North–South, and the Trans-Afghan Corridor — may create a strong multiplier effect and reduce transport costs and delivery times along key Eurasian trade routes.

It should be noted that Eurasian multimodal digital corridors are, by their nature, information networks serving international supply chains consisting of national segments with different levels of digitalization. However, communication theory demonstrates that network capacity is determined by interoperability between segments and by the performance of the weakest element. This means that development and deployment of national MMDC segments should initially comply with interoperability requirements and be implemented synchronously in order to avoid situations where completed national segments remain idle while waiting for missing segments to be finalized. During the digitalization of the national transport network and development of MMDC segments, fragmentation of technological systems across transport modalities, as well as outdated IT systems, may become significant challenges requiring effective integration solutions and competent orchestration of multimodal business processes.
