Automated Driving Safety Evaluation Framework
Automated Driving Safety Evaluation Framework Ver. 4.0 -Guidelines for Safety Evaluation of Automated Driving Technology-
Assuring the safety of automated driving technology requires a common safety evaluation methodology. In response to this need, the Japan Automobile Manufacturers Association (JAMA) published the Automated Driving Safety Evaluation Framework Ver. 4.0 online in December 2025.
JAMA released the first version of this framework “Ver. 1.0” in October 2020, and subsequently updated it to “Ver. 3.0” in December 2022 by expanding the scope of traffic flow scenarios from limited-access highways to include ordinary roads, as well as by enhancing the practicality of perception evaluation for vehicle sensors.
In Ver. 4.0, JAMA has further expanded the framework by adding scenario descriptions that explicitly address vulnerable road users, such as pedestrians and cyclists, and by introducing blind-spot scenarios that take characteristics of ordinary roads into account. In addition, explanations in each chapter have been enhanced and the overall structure of the document has been reviewed and revised.
Although these guidelines are intended primarily for application by JAMA member manufacturers in evaluating and verifying safety throughout the planning, design, and assessment phases of automated driving technology development, it is hoped that they will also serve as a useful reference for suppliers and other related stakeholders engaged in technology development.
JAMA believes that this framework will help promote domestic and international projects related to safety evaluation of automated driving technology and contribute to the development of international standards and regulations.
Note: JAMA will continue its examination of safety assessment methods for automated driving technology and may consequently revise or make new additions to its guidelines, releasing updated versions accordingly.
