The TrustMe project develops a safety case for autonomous buses. A safety case is mostly based on information from the developers and refers to one or more relevant safety standards. The bases for a safety case are the defined safety standards and proof of compliance, based on the paper trails left by each required activity. A trust case is different and trust and safety assessments are not necessarily correlated. In order to make self-driving buses a success they need to be considered trustworthy. Thus, we need a “Trust case”. To ensure that the vehicles are safe and to inform the public, we have developed both a developer safety case and safety case for the public. To take care of the remaining factors we have developed a “Trust case”. The trust case has been developed as part of literature studies, surveys and interviews. We have made a survey of 311 passengers and interviewed 18 autonomous bus passengers. Based on literature studies, surveys and interviews, we have proposed a set of issues that should be included into a “Trust case”. By providing the public with a “Trust case” together with a “safety case for the public” we will help manufacturers of autonomous vehicles and operators to gain public trust.
