In shared road space，human driving interaction behavior has the social characteristics of considering the impact on surrounding vehicles. Lacking the understanding of such social characteristics，autonomous vehicles often struggle to estimate the potential impact of their behavior on surrounding vehicles，thus falling into over conservativeness of decision-making dilemma. A game-theory-based social driving interaction model is constructed by introducing in the behavioral characteristics of drivers considering the impact on surrounding vehicles to capture the action dependencies among road users. With this model，a generalized measurement，utility term of interaction activeness （UTIA），is proposed to quantify the potential impact of the host vehicle's anticipated behavior on its interactants. By introducing the UTIA into the planning objective，the interaction activeness of motion planning algorithm can be directionally adjusted. The results of highway exit experiments show that without compromising safety，enhancing interaction activeness can improve the success rate of the exit task within a given distance by 3.9% and 5.2% for optimization-based and sampling-based motion planning algorithm，respectively.
