Aspects of Data Transfer and Synchronization for Vulnerable Road Users Emergency Scenarios Based on Blockchain Technology in ITS

The paper presents a study of response scenarios in an intelligent transport system, in which pedestrians are participants, to emergency situations and their prevention. Pedestrians are included in the VRU (Vulnerable Road Users) category within the general ITS architecture and are most susceptible to accidents due to the lack of movement control. Scenarios for interaction with such traffic participants may include not only rules for responding and providing assistance as soon as possible, but also identifying the initiator of the incident for the purpose of further control and prevention of situations of a similar nature. The authors of the work propose the use of blockchain technology to ensure data safety, as well as the option of building an ITS architecture with a module for monitoring incident data and timely response. The paper provides mathematical calculations of the possibility of using blockchain technology within the framework of the proposed concept and modeling.
