The invention provides an action probability estimation device and method, and a traffic safety assistance system. The present invention appropriately estimates an action probability of a steering action that can be executed by a driver of a target vehicle that is a target of driving assistance in accordance with a traffic condition. This behavior probability estimation device is provided with: a risk calculation unit that calculates a risk index value that is a numerical value indicating the degree of risk of collision between traffic participants around a target vehicle and the target vehicle; and a probability estimation unit that estimates an action probability, which is a probability that the driver performs a prescribed maneuvering action in the target vehicle, on the basis of the risk indicator value and driver characteristics of the target vehicle, the driver characteristics including a confidence level and a perseverance level when a dangerous situation occurs. The self-confidence level is a numerical value indicating the level of self-confidence of the driver with respect to the own driving skill, and the perseverance performance level during the dangerous situation is a numerical value indicating the level of tendency of the driver to know the perseverance performance of the dangerous behavior.

    本发明提供行动概率估计装置、方法以及交通安全辅助系统。适当地估计成为驾驶辅助的对象的对象车辆的驾驶员根据交通状况能够执行的操纵行动的行动概率。行动概率估计装置具备:风险计算部,其计算风险指标值,该风险指标值是表示对象车辆周围的交通参加者与对象车辆的碰撞风险的大小的程度的数值;以及概率估计部,其基于风险指标值和对象车辆的驾驶员特性,估计行动概率,该行动概率是驾驶员在对象车辆中执行规定的操纵行动的概率,驾驶员特性包括自信等级和危险状况时毅然执行性等级,该自信等级是表示驾驶员的关于自己的驾驶技能的自信的高低的程度的数值,该危险状况时毅然执行性等级是表示驾驶员明知道危险毅然执行行动的倾向的大小的程度的数值。
