This article proposes a classification of vehicle connectivity levels oriented towards traffic management tasks. The classification comprises 6 levels (0–5) with sub-levels (a and b) and is based on a combination of two key dimensions: addressability and mode of participation in management. The proposed connectivity level gradation is equivalent to the stages of evolution of communication architectures in distributed computing systems — from broadcasting to full agent orchestration. This correspondence enables the transfer of results from the field of distributed systems (scalability, fault tolerance, consistency) to the design of traffic flow management system architectures. The methodological choice of a linear approach with faceted reinforcement is justified through a systematic comparison of four classification approaches across five quality criteria.
