Abstract:This report reviews existing pre-crash scenario typologies and various proposed behavioral competencies in literature that may be relevant to automated driving systems (ADSs) and selects five example scenarios to facilitate exploration of elements that may be helpful in characterizing them. The selected scenarios were: rear-end scenario, lead vehicle lane change scenario, vulnerable road user scenario, crossing path scenario, and a merge scenario. From these five sample scenarios, scenario descriptions were created by first leveraging existing test track procedures when available and then modifying them such that they can be executed with ADSs. These scenario descriptions were broken down into five categories: initialization, environment, principal other vehicle, traffic, and subject vehicle status. For each one of these categories, the study targets identifying a preliminary list of elements necessary to describe the ground truth scenario information.
