Description

technical field [0001] The invention discloses an A3C-SRU-based intelligent vehicle merging algorithm and system, belonging to the field of automatic driving. [0002] technical background [0003] In the entire decision-making system of unmanned vehicles, the problem of merging traffic has always been a difficult problem, and it is also a key problem that has to be solved. For human drivers, about 20% of traffic accidents occur at ramp intersections. Incoming traffic mainly needs to be considered in the complex traffic confluence scene, the traffic flow on the main road, and the changes in the surrounding environment at the intersection. Usually, an merging behavior involves a series of complex decision-making behaviors. The decision-making behavior in the process of inflow often has a great impact on the efficiency of traffic flow and the safety of inflow. However, when faced with the scene of merging traffic, the unmanned vehicle decision-making system cannot intelligentl...
