Voertuignaarnet

Voertuignaarnet is a term used in discussions of intelligent transportation systems to describe an integrated, vehicle-centric network architecture that connects road vehicles with each other, with road-side infrastructure, and with cloud services. The concept envisions vehicles as active data nodes that share information to improve safety, mobility, and efficiency.

It encompasses in-vehicle networks (such as CAN and Ethernet), vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-network (V2N) connectivity, using technologies including C-V2X, ITS-G5, and cellular 5G. Data exchanged may include location, speed, hazards, traffic signals, and diagnostics, supported by standardized data models and secure communication.

Voertuignaarnet aligns with, but is not limited to, ITS standards and protocols from ETSI ITS and 3GPP for V2X, as well as evolving edge and cloud architectures. Interoperability depends on harmonized data formats, security, and privacy protections across vendors and regions.

Typical applications include real-time safety alerts, cooperative adaptive cruise control, dynamic routing, traffic management, remote diagnostics, and fleet optimization.

Challenges include privacy and cybersecurity, latency and reliability requirements, cross-brand interoperability, spectrum allocation, costs, governance, and liability considerations. As a concept, voertuignaarnet guides research and pilot programs in Europe, Asia, and other regions, with several pilots showcasing improved safety and efficiency but without a single global implementation.
