A mechanism for managing algorithms for building data storefronts in intelligent transport systems

The article considers the task of increasing the flexibility and manageability of the processes of building data storefronts in intelligent transport systems. The relevance of the research is due to the need for rapid changes in data processing algorithms in the context of dynamically changing requirements and a large volume of incoming information from transport infrastructure and telematics sources. A mechanism for managing algorithms for calculating data marts is proposed, providing centralized storage, validation, and dynamic application of computational rules without modifying the main code of ETL processes. The architecture of the software solution has been developed, including a user interface, a server application, and a repository of rules in a database, as well as the integration of the mechanism into the processes of building data marts. A mathematical model of the application of computational rules is presented, formalizing the process of selecting and composing data processing functions. Functional testing of the developed mechanism was carried out, which confirmed the correctness of its operation and the possibility of using it in various operating modes, including the pilot implementation of algorithms. The practical significance of the work lies in the possibility of using the proposed mechanism in intelligent transport information systems to reduce the time needed to implement algorithm changes and increase the reliability of data processing processes.
