Research on the Influence of Surrounding Objects on the Propagation of Connected Vehicle Signals in 2D and 3D Models

At present, global processes occurring at the international level, related, in particular, to climate change, the need to improve road safety, as well as to improve the efficiency of vehicle use, dictate the need to use intelligent transportation systems, which should improve the safety and efficiency of transportation in the city and beyond. To ensure the safety of vehicles, it is necessary to integrate modern information and communication technologies into the transportation infrastructure, which will improve the efficiency of traffic flow management and, consequently, road safety. Before integrating new technologies into the transportation system, it is necessary first of all to test them under safe conditions. Computer simulation modeling is used for this purpose. There are a number of challenges that arise in the design of these systems, especially related to the effects of the environment and physical objects on the propagation of wireless signals. These challenges highlight the importance of signal propagation modeling for evaluating transport systems for stability and immunity of transport networks. In this paper, an overview of existing wireless vehicular communication technologies and standards, a review and comparative analysis of 2D and 3D signal propagation model is carried out. The report consists of 54s, 6 chapters, 15 figures, 4 tables, 34 sources. Keywords: intelligent transportation systems, connected transportation, signal propagation.
