Experimental Method for Evaluating Pedestrian Psychobiology Indexes in Traffic Emergency Scenarios

A personalized and emotion based virtual simulation model for pedestrian‐vehicle collision avoidance

“…Consider the behavior of pedestrians avoiding vehicles as an emergency response to perceived danger. As introduced in Section 1, pedestrians generate negative emotional value when they detect a possible collision with a vehicle, 4 and the intensity of the emotional value is reflected in the speed of avoiding the vehicle. The driver model is divided into careful and aggressive personalities based on personality parameters.…”

“…As the weak side, pedestrians will have more obvious psychological reactions to the upcoming collision. They will have negative emotions such as panic, tension, anxiety, and fear 4 . Since the existing simulation models cannot well describe the heterogeneity of pedestrian‐vehicle collision avoidance, We try to use the personality model in psychology to define the personality characteristics of traffic participants, and address the problem by establishing a reasonable personality‐behavior mapping relationship.…”

“…In real traffic environments, when pedestrians and vehicles are at risk of collision, both of them need to make a quick decision to avoid accidents. At this time, personal cognitive, emotional, behavioral, and psychological factors need to be considered comprehensively 4 . Different pedestrians and vehicle drivers will have different collision avoidance strategies 4,5 .…”

“…They will have negative F I G U R E 1 Pedestrian-vehicle collision avoidance simulated by the proposed model emotions such as panic, tension, anxiety, and fear. 4 Since the existing simulation models cannot well describe the heterogeneity of pedestrian-vehicle collision avoidance, We try to use the personality model in psychology to define the personality characteristics of traffic participants, and address the problem by establishing a reasonable personality-behavior mapping relationship. Considering that personality traits will affect emotion to some extent, 7 this paper hypothesizes that emotion plays a transitional role in the influence of personality traits on pedestrian behavior.…”

“…At this time, personal cognitive, emotional, behavioral, and psychological factors need to be considered comprehensively. 4 Different pedestrians and vehicle drivers will have different collision avoidance strategies. 4,5 The heterogeneity of pedestrian and vehicle behavior is a factor that cannot be ignored in pedestrian-vehicle collision avoidance simulation studies.…”
