Summary
This document is Waymo’s 2021 Safety Report, which outlines the company’s safety program, technical architecture, and validation methods for its fully autonomous driving system, known as the "Waymo Driver." The report is motivated by the urgent need to improve road safety, citing that 1.35 million people die annually in traffic crashes worldwide. Waymo aims to demonstrate that its Level 4 autonomous technology can operate safely without human intervention, thereby saving lives and improving mobility for those unable to drive. The report details a "Safety by Design" approach that integrates safety into every development stage, drawing on best practices from aerospace, automotive, and defense industries. The system addresses five distinct safety areas: behavioral, functional, crash, operational, and non-collision safety. Hazard identification methods include System-theoretic Process Analysis (STPA), Fault Tree Analysis (FTA), and Design Failure Modes and Effects Analyses (DFMEA). The autonomous vehicle utilizes a redundant sensor suite comprising lidar, cameras, radar, and inertial measurement units to achieve a 360-degree view up to 300 meters. The software architecture consists of perception modules to detect and classify objects, behavior prediction models to anticipate road user intent, and a planner that executes defensive driving maneuvers. The system operates within a defined Operational Design Domain (ODD) and includes a "Minimal Risk Condition" fallback mechanism to safely stop the vehicle in case of system failure or conditions outside the ODD. Waymo validates its technology through extensive testing, including over 15 billion miles of simulation and more than 20 million miles of autonomous driving on public roads. The validation process covers base vehicle safety, hardware reliability, and software behavioral competencies. The report emphasizes that the system is designed to handle the entire dynamic driving task without human monitoring, avoiding the "handoff problem" associated with lower-level automation. Specific testing includes crash avoidance capabilities and ensuring the vehicle complies with local traffic laws and unique road rules within its geographic areas of operation. The significance of this report lies in its comprehensive documentation of how a commercial entity addresses the 12 safety design elements outlined by the U.S. Department of Transportation. By detailing its rigorous hazard analysis, redundant hardware design, and extensive validation metrics, Waymo seeks to establish public trust and regulatory confidence in fully autonomous vehicles. The report concludes that fully autonomous driving technology holds the potential to transform mobility and significantly reduce traffic fatalities, provided that safety remains the core focus of development and deployment.
