Abstract
The aim of the paper is to investigate the application opportunities of the Unified Modeling Language (UML) for the description of transportation systems. The first part of the paper reviews the architecture of the traffic models and gives a short survey of traffic simulation models. The deficiency of the currently used traffic simulation models is either that they can´t efficiently integrate human decision-making process in the course of describing real traffic situations or they completely neglect the human factor [1]. The second part of the paper contains our approach aiming at the UML-based description of traffic problems integrated with the human decision. Using UML notation for analysis and modeling the behavior of a complex system allows its correctness to be ensured and criticality requirements to be achieved. The UML ensures a standard solution for high quality systems modeling.
