JAMA Builds Japan Autonomous Driving Platform for 2028

JAMA Develops Infrastructure-Cooperative Autonomous Driving System

The Japan Automobile Manufacturers Association, Inc. (JAMA) plans to develop an infrastructure-cooperative traffic system for autonomous driving in Japan, with regional implementation targeted from 2028. The JAMA autonomous driving platform will use an information control platform to integrate multiple data sources, including vehicle information supplied by individual manufacturers, remote support systems for autonomous driving, and public information such as traffic congestion updates. The initiative is intended to provide autonomous vehicles with information about blind spots and other hazards that onboard systems may not fully detect independently, with the broader objective of reducing traffic accidents.

Information Control Platform Will Integrate Multiple Data Sources

The planned information control platform is designed to coordinate data that currently exists across different vehicle manufacturers, autonomous driving support systems, and public information sources. Under the initiative, Japan will use the platform to bring these inputs together and provide relevant information to autonomous vehicles. The approach is intended to supplement vehicle-based sensing by supplying information about conditions that may be difficult for an individual vehicle to identify. Traffic congestion information and data relating to hazards or blind spots are among the types of information expected to contribute to the system's operation.

JAMA Targets 2026 Proof-of-Concept Phase

The development schedule begins in 2026 with a proof-of-concept (PoC) phase intended to clarify the system's effectiveness, specifications, and potential contribution to accident reduction. During this stage, the Japan Automobile Manufacturers Association Inc will examine how the infrastructure-cooperative approach can support autonomous driving operations and determine the requirements for a broader deployment. The PoC is also expected to provide a basis for refining the technical design before the next development stage. This staged approach links initial testing with subsequent construction, optimization, and safety verification of the platform.

Platform Construction and Safety Verification Planned for 2027

In 2027, JAMA plans to construct the information control platform and use that stage to coordinate data integration, optimize the overall system, and verify safety. The development process is intended to establish how information from separate sources can be managed as part of a coordinated infrastructure-supported autonomous driving environment. Safety verification will be particularly important because the platform is intended to influence how autonomous vehicles respond to information beyond their onboard sensing capabilities. The 2027 phase therefore represents the transition from proof-of-concept evaluation toward a system capable of supporting implementation across multiple regions.

Regional Implementation Is Planned From 2028

Following the proof-of-concept and platform construction phases, JAMA intends to begin implementation across multiple regions in 2028. The planned rollout would establish an infrastructure-cooperative autonomous driving system in Japan that combines vehicle-generated information, remote support capabilities, and public traffic information. JAMA also intends to establish the Japanese-style autonomous driving platform at an early stage and ultimately pursue international standardization. If the development and safety verification stages establish the intended effectiveness, the initiative could provide a framework for coordinating infrastructure and vehicle information as autonomous driving systems expand.

Industry Impact & Outlook

JAMA's initiative could influence how automakers, infrastructure operators, remote support providers, and public authorities coordinate information for autonomous driving in Japan. By extending vehicle capabilities with shared infrastructure data, the approach addresses situations where onboard systems may have limited visibility of hazards or changing traffic conditions. The planned progression from a 2026 PoC to 2027 platform construction and 2028 regional implementation provides a defined path for testing and deployment. The longer-term objective of international standardization also means that the specifications and operating model established through the Japanese program could become relevant beyond the initial domestic rollout if they demonstrate sufficient safety and effectiveness.
