Pedestrian behavior is based on both cognitive processes and the construction of social knowledge and representations. The results of various studies we have conducted showed that pedestrian compliance with road rules varied according to crossing regulation, built environment, gender and age. They also addressed the role of rule perception and internalization. Finally, they showed how informal learning, through observation, of road rules can explain the construction of conventional level rules, the application of which is contextual. These different elements demonstrated how knowledge of social norms can be an issue for the autonomous vehicle.
