This work continues the topic of blockchain-enabled intelligent transport system design and focuses on groups of messages (transactions) suitable for such a system. Precisely, the work proposes to extend the known set of messages with two new groups – traffic optimization messages and commercial offers/requests. The messages of the first group allow the implementation of traffic optimization tools based on artificial intelligence and other traffic forecasting tools available for an intelligent transport system. For example, it is possible to increase efficiency of intelligent transport system throughput utilization by instructing a driver to slow down, speed up or to take a detour route when necessary. At the same time messages of the second group (commercial offers/requests) contribute to road safety through making vehicles maintenance services available intime. The combination of a two-layer architecture for the interaction of digital entities, the PBFT-based consensus mechanism, elaborated block structure and the messages disclosed in this work contribute to the scientific novelty and uniqueness of the proposed blockchain implementation for an intelligent transport system.
