Modeling road user response timing in naturalistic settings: a surprise-based framework

Understand

There is currently no established method for evaluating human response timing across a range of naturalistic traffic conflict types.

• Traditional notions derived from controlled experiments, such as perception-response time, fail to account for the situation-dependency of human responses and offer no clear way to define the stimulus in many common traffic conflict scenarios.
• As a result, they are not well suited for application in naturalistic settings.
• Our main contribution is the development of a novel framework for measuring and modeling response times in naturalistic traffic conflicts applicable to automated driving systems as well as other traffic safety domains.
