Advances in transportation safety and efficiency enables road users to eventually care about travel experiences and satisfactions. Prosocial behavior is an important factor affecting wellbeing in mobility. To better understand what leads to prosocial behaviors, and how people experience such actions, detailed analysis on behaviors from various levels of prosocial behaviors. This paper utilizes a naturalistic dataset for prosocial behaviors, with multimodal signals. We analyze road user behaviors and physiological responses with effort, obligation, and satisfaction of prosocial behaviors. The results suggest significant behavioral patterns across different conditions related to prosocial behaviors.
