Public perception of Autonomous Vehicle Safety in San Francisco Factsheet

Introduction

The safety performance of autonomous vehicles (AVs) is fundamental to protecting all road users, but public perception of their safety is equally important, as it shapes trust, acceptance, and willingness to share the road with this technology. The city of San Francisco provides a unique environment to study safety perceptions of AVs for different road users given that they have operated on city streets for years, allowing residents to experience substantial amounts of interactions with this technology. The UC Berkeley Safe Transportation...
