Abstract:

There are many factors that affect autonomous vehicles' behavioral decision-making in the traffic environment. It is very important for the safety of autonomous vehicles to handle uncertainty factors accurately and timely. To this end, we design a behavioral decision-making model of Bayesian network (BN) based on classification of human driving behaviors. The decision tree classification algorithm is used to classify the driving behaviors of human driving vehicles, The BN is used to model the driving scene and create the best driving behavior. It not only analyzes the human driving behavioral style timely, but also takes into account the uncertain factors in the driving scene. We design the PreScan simulation experiments, the simulation results show that the behavioral decision model can provide safe and reasonable behavior of autonomous vehicles.

Key words: autonomous vehicles, behavioral decision-making, Bayesian network (BN), decision tree, PreScan simulation
