摘要:

自动驾驶汽车(AV)需要与其他交通参与者进行交互,这些交通参与者可以是合作的或积极的,也可以是专注的或疏忽的。这些不同的特征可以导致完全不同的交互行为。因此,为了实现安全高效的自动驾驶,自动驾驶汽车在规划自己的行为时需要意识到这些不确定性。在本文中,我们制定这样的行为规划问题作为一个部分可观察的马尔可夫决策过程(POMDP)的其他交通参与者的合作被视为一个不可观察的状态。在不同的合作程度下,我们通过最大似然原理从真实的交通数据中学习人类行为模型。在此基础上,采用蒙特卡罗树搜索方法求解POMDP问题。通过仿真和实际交通数据对算法进行了验证,结果表明,该算法能够在无碰撞的情况下成功地完成车道变换。

英文摘要:

Autonomous vehicles (AVs) need to interact with other traffic participants who can be either cooperative or aggressive, attentive or inattentive. Such different characteristics can lead to quite different interactive behaviors. Hence, to achieve safe and efficient autonomous driving, AVs need to be aware of such uncertainties when they plan their own behaviors. In this paper, we formulate such a behavior planning problem as a partially observable Markov Decision Process (POMDP) where the cooperativeness of other traffic participants is treated as an unobservable state. Under different cooperativeness levels, we learn the human behavior models from real traffic data via the principle of maximum likelihood. Based on that, the POMDP problem is solved by Monte-Carlo Tree Search. We verify the proposed algorithm in both simulations and real traffic data on a lane change scenario, and the results show that the proposed algorithm can successfully finish the lane changes without collisions.
