Development of an OBU-RSU interaction model within a classical mobility scheme and utilizing clustering to ensure efficient data transmission within a dynamic system. Additionally, an alternative scheme was proposed, which simulated mRSU flows, representing a dynamic fog, operating on a taxi principle, and directing mRSU movement towards areas of peak load. 3. Presentation of a developed simulation system for the analysis and synthesis of V2X system applications. This system was utilized to determine the average time required for system stabilization concerning caching and losses. Conclusions regarding the applicability of approaches to describe efficient OBU-RSU interaction within the V2X system are formulated. The developed simulation model is designed to address traffic optimization problems in the event of accidents. The study focuses on V2X applications that utilize highly mobile RSUs as fog nodes. In the future, the authors plan to scale the simulation model to increase the number of V2X applications it can support. It should be noted that the current version of the model can also be adapted for other V2X applications with appropriate modifications. The main advantages of the model are its simplicity, operational efficiency, and flexibility in adapting to specific tasks. The primary objective set by the authors is to create a simulation system for V2X system elements that enables data loss optimization during emergency situations, while meeting the following conditions:  
1. The simulation system includes four elements: OBU, RSU, EC, and CLOUD. 2. The system is independent of the map used for simulation. A new map can be loaded into the system, converted into a graph, and used for simulations. 3. The simulation system is a single software unit that allows for road network simulation, utilizing the core V2X system elements and calculating data loss during element interaction. The goal is not to create custom software to replace existing solutions. The authors propose an alternative approach to the problem of analyzing and optimizing V2X systems. Existing simulation systems do not provide a comprehensive solution to the defined problem. They require the combined use of multiple simulation environments and applications. For example, OMNeT++ enables calculations and analysis of simulation results, SUMO visualizes the data collection process from interacting objects, and VEINS extends OMNeT++ capabilities for V2X-specific tasks. To accomplish the task defined by the authors, it is necessary to use all the described applications together, leading to increased algorithmic and time complexity of the solution algorithms. The remainder of the paper is structured as follows: Section 2 provides an overview of the existing literature on the relevant subject area. Section 3 formulates a description of the system model and the applied mathematical framework. The description and structure of the proposed computer model, its general scheme, key numerical simulation parameters, primary challenges, and their solution methods are presented. A description of the simulation system's operation is also provided. Section 4 presents and describes the numerical simulation results aimed at validating the theoretical findings and analyzing them in various system configurations. Finally, Section 5 concludes with final remarks and discussion.
