Abstract


The field of road accidents requires a specific geoinformation system to provide functionalities for creating and managing intelligent geographically-oriented spatial-temporal models for spatial analysis. The aim of this study is to present a conceptual model of a geoinformation system of road accidents, defined in accordance with the requirements of international standardization. The approach for international standardization and conceptual modeling of geoinformation, as well as the principles of object-oriented modeling, methods of abstraction and classification were used. As a result, a Use Case and a Class diagram, presented in the Unified Modeling Language, were developed. In conclusion, the standardized conceptual model is defined as an important initial stage in the creation of a geoinformation system of road accidents, which is related to the correct formalized description of the domain and the presentation of structural types of geoinformation processes, and subsequently can be automatically and in the unified manner transposed into a functional physical model for the analysis of road accidents.
