Before revision:  Besides, a sampling-based inverse reinforcement learning (IRL) algorithm that learns the reward function from human naturalistic driving data is also developed. A polynomial trajectory sampler is adopted to generate feasible trajectories and approximate the partition function in the maximum entropy IRL framework, and a dynamic and interactive environment is built upon the static driving dataset to estimate the generated trajectories considering the mutual dependency of agents' actions .
