• Title: Pedestrians play chicken with an autonomous vehicle
• Abstract summary: The game theoretic Sequential Chicken model has shown that, like human drivers, AVs can resolve this problem by trading credible threats of collision or larger risks of less severe invasion of personal space against the value of time due to yielding delays.<n>This paper shows that pedestrian behavior under experimentally constrained safety conditions can be well fitted by Sequential Chicken, with a low time value of collision, suggestive of their planning to avoid proxemic personal space penalties as well as actual collisions.

• Abstract: Automated vehicles (AVs) are commonly programmed to yield unconditionally to pedestrians in the interest of safety. However, this design choice can give rise to the Freezing Robot Problem in which pedestrians learn to assert priority at every interaction, causing vehicles to stall and make no progress. The game theoretic Sequential Chicken model has shown that, like human drivers, AVs can resolve this problem by trading credible threats of very small risks of collision or larger risks of less severe invasion of personal space against the value of time due to yielding delays. This paper presents the first demonstration and evaluation of this approach using a real AV with human subjects and shows that pedestrian behavior under experimentally constrained safety conditions can be well fitted by Sequential Chicken, with a low time value of collision, suggestive of their planning to avoid proxemic personal space penalties as well as actual collisions.

• The risk ethics of autonomous vehicles: a continuous trolley problem in regular road traffic [0.0]
  We argue that autonomous vehicles (AVs) distribute risks between road users in regular traffic situations, either explicitly or implicitly. Using an interactive, graphical representation of different traffic situations, we measured participants' preferences on driving maneuvers of AVs. Our participants were willing to take risks themselves for the benefit of other road users suggesting that the social dilemma of AVs may lessen in a context of risk.
