Blockchain Technologies for Validation of Priority Vehicles in ITS

The analysis of the possibility of using distributed networks, in particular, the blockchain network, smart contracts, as a control mechanism for controlling messaging and ensuring the digital security of the network is carried out in the work. The paper describes the concept of priority passage and its provision using distributed network mechanisms. Two priority passage scenarios are considered, as well as a messaging scheme for general cases of priority passage and the case of overlapping priority routes. Also, the paper presents mathematical studies of evaluating the possibility of a blockchain network depending on its performance, as well as approbation of calculations on model stands on networks with PoW and LPoS consensus algorithms.
