Japan V2X Communication Project Advances Autonomous Driving Safety Verification

A consortium of eight Japanese organizations has launched a collaborative initiative to evaluate vehicle-to-everything communication technologies designed to enhance the safe operation of autonomous vehicles. The project brings together KDDI Corporation, Mitsubishi Research Institute, Tier IV, and NEC Corporation, along with several other partners, to assess how communication infrastructure can strengthen vehicle safety and operational reliability in autonomous driving environments.

The initiative will examine communication technologies operating across the 700 MHz and 5.9 GHz frequency bands, while also leveraging existing 4G and 5G mobile communication networks. Through testing on both public roads and highways, the participating organizations aim to evaluate how in-vehicle systems can effectively exchange information with external infrastructure and connected systems. The findings are expected to support broader deployment and commercialization efforts for V2X communication technologies.

Organizations Participating in the V2X Verification Project

The project includes a diverse group of technology, research, and mobility-focused organizations working together to establish communication requirements for future autonomous transportation systems. In addition to the four leading participants, the collaboration also includes MRI Research Associates, Oki Electric Industry Co., Ltd., SMICIP, and T2 Inc. Their combined expertise is expected to contribute to a comprehensive assessment of communication performance, reliability, and infrastructure readiness.

Project Participants and Roles

Focus on Communication Requirements for Safe Autonomous Driving

A primary objective of the project is to systematically identify the operational conditions and communication requirements needed to support V2X applications in real-world driving scenarios. By utilizing actual vehicles during testing, the consortium will validate communication performance under practical road conditions and examine how network technologies can support safe autonomous vehicle behavior.

Technology Evaluation Across Multiple Networks

The verification activities will cover communications over dedicated frequency bands as well as commercial cellular networks. Evaluating multiple connectivity options will help determine suitable approaches for future autonomous mobility services while supporting interoperability between vehicles, roadside infrastructure, and external systems. The resulting framework is expected to provide valuable guidance for expanding V2X deployment across transportation networks in Japan.
