Abstract
Intelligent transportation systems (ITS) are a today´s hot topic, especially in the context of the development of information technologies, which can be employed in transportation. Although the scope and the technical solution of these systems may vary, they are frequently based on VANET (Vehicular ad hoc network), i.e. a communication network, which is primarily generated among the moving subjects, which form ITS. Given the highly dynamic VANET, the questions are raised as to the data transmission. This paper is aimed to make a detail analysis of the communications within VANET using the simulation model, which includes the static infrastructure of ITS and to experimentally verify the impact of this infrastructure on the dynamics of information spreading in ITS. The authors present the results obtained from a few different scenarios, which have been tested.

Summary
As soon as the conditions for their emergence appeared, intelligent transportation systems (ITS) became a target of investigations. The main thing was an availability of appropriate technologies for a wireless data transmission and the performance of the IT equipment. This technology is currently changing rapidly and ITS is no longer an established concept. Some aspects of ITS need to be addressed. One can mention the ITS structure itself, which may be, from the data processing viewpoint, centralized or distributed and based on the peer-to-peer like systems and networks. There are open questions as far as the personal data protection and security are concerned. The necessary technical infrastructure continues to be discussed, as well, i.e. whether the existing technical solutions are to be used or whether they are to be supplemented or extended with other elements
