主 题:Markov decision process Decision-making Dynamic programming Self-driving cars
摘 要:Purpose–Decision-making is one of the key technologies for self-driving *** high dependency of previously existing methods on human driving data or rules makes it difficult to model policies for different driving ***/methodology/approach–In this research,a probabilistic decision-making method based on the Markov decision process(MDP)is proposed to deduce the optimal maneuver automatically in a two-lane highway scenario without using any human *** decision-making issues in a traffic environment are formulated as the MDP by defining basic elements including states,actions and basic *** and reward models are defined by using a complete prediction model of the surrounding *** optimal policy was deduced using a dynamic programing method and evaluated under a two-dimensional simulation ***–Results show that,at the given scenario,the self-driving car maintained safety and efficiency with the proposed ***/value–This paper presents a framework used to derive a driving policy for self-driving cars without relying on any human driving data or rules modeled by hand.
