As ADAS and highly automated systems take to the roads, one thing has become clear: automated systems need to better understand people. Industry accepted physics models don’t go far enough to protect and understand vulnerable road users. By assessing a persons’ current position, velocity, acceleration and rotation over time, the system then uses this information to forecast the future position of an individual. From this crossing in front of the vehicle, or any similar action, can be inferred. This physics model approach is solely based on variables obtained from the bounding box displacement, but doesn’t do a thorough enough job to understand the psychology behind human action or inaction. In summary: human behaviour is too complex, leading to false positives or failure to predict intention altogether. Behavioural psychology can help.
