- W4386066159 abstract "Efficient and safe global path planning for vehicles is a key issue in the field of navigation. However, in large-scale maps, traditional A <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>*</sup> algorithms have the problem of long search times, which seriously affects planning efficiency. This article proposes a global planning algorithm called RRT-A <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>*</sup> based on large-scale maps, considering multiple path costs, and designing dynamic step size adjustment. The results show that the algorithm proposed in this article has much shorter planning time than A <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>*</sup> , the time consumption is close to RRT and has lower path cost than RRT algorithms. Therefore, it can greatly improve the efficiency of path planning in large-scale maps." @default.
