Application of Use Cases and the UML language in the design of Intelligent Transportation Systems

Abstract

The purpose of this paper is to analyse the applicability of the description of use cases and the UML language that takes them into account in the process of designing Intelligent Transportation Systems (ITS). These systems are built using standardized solutions and devices, but the system itself and the individual organizational solutions used therein are individually tailored to the needs of the employer - the manager of the road network on which the system is implemented.  The first stage of the project may include verbal descriptions of the requirements, proposals for solutions, relations between system elements, contents of databases, etc. However, the next stages of the work should involve the use of tools to formalize the record so that it is understandable to the entire project team, the contractors of the system elements, and then form the basis for the development of design and detailed documentation. The tools that can be used in the design process of an ITS solution are, described in the paper use cases that define the interaction of system users ("actors") with the system, and the UML language used in the design of information systems. The paper describes the legal basis for ITS solutions, ways of defining use cases, the UML, including use case diagrams, behavioural diagrams and structural diagrams.  Examples of the application of the UML to describe the design of an ITS system are also presented.
