Problems solved by technology
[0006] 1. The basis for scene layering is not supported by sufficient theoretical methods, and the distinction between scenes in each layer is not clear enough;
[0007] 2. The current research is mostly based on the analysis of known scene attribute elements, and the determination of scene attribute elements is mostly subjective analysis, lacking an objective scene attribute element extraction method as a support;
[0008] 3. The scene attribute elements considered in the existing research are not comprehensive enough, and the description of the scene is not complete enough;
[0009] 4. There is a lack of standardized definitions for scene attribute elements in existing research, and there is no unified scene basis for subsequent research

The invention discloses an autonomous traffic system scene demand analysis method and device, and the method comprises the steps: carrying out the layering abstraction of a typical scene of an autonomous traffic system through employing a tree structure layering method, and defining the boundary of each layer of scene; according to a triangular model of an activity theory, obtaining attribute elements related to the typical scene of each level; the typical scene of each level is subjected to standardized description, and the standardized description of the typical scene comprises a plurality of attribute elements; and performing text similarity matching on the attribute elements of the typical scene and an autonomous traffic system demand library to obtain a target scene demand. According to the method, a more scientific and effective scene analysis method can be used for carrying out comprehensive layered abstraction and attribute element analysis on a complex traffic system scene so as to realize standardized description on the traffic scene and further research requirements and services contained in a typical scene of an autonomous traffic system; the method can be widely applied to the technical field of traffic data processing.
Description
technical field [0001] The invention relates to the technical field of traffic data processing, in particular to a method and device for analyzing the scene requirements of an autonomous traffic system. Background technique [0002] With the rapid growth of traffic volume, the orderly construction and use of all-round transportation infrastructure, and the mutual promotion of emerging technologies and transportation services. In the face of the surging demand for passenger and freight transportation, the construction of a transportation system that can realize self-organizing operation and provide users with autonomous services is gradually emerging, that is, Autonomous Transportation System (ATS). [0003] The autonomous transportation system is driven by emerging technologies, based on the business logic of autonomous perception, learning, decision-making, and response, and completes the transportation of people and objects through self-organized operation and autonomous s...
