An analysis server for analyzing factors of a dangerous road section by receiving a precise road map and a basic safety message (BSM) provided from an autonomous vehicle, according to the present invention, comprises a communication unit, a storage unit and a control unit, wherein the control unit controls the communication unit and the storage unit so as to accumulate the BSM or the precise road map in the storage unit for a specific period of time, configures a dataset by calculating an independent variable from the BSM and calculating a dependent variable from the precise road map, generates and trains a dangerous road section classification model by applying an XGBoost algorithm to the dataset, calculates importance for each factor of the dangerous road section, and performs factor analysis on the dangerous road section on the basis of the calculated importance for each factor.

    Un serveur d'analyse permettant d'analyser des facteurs d'une section de route dangereuse en recevant une carte routière précise et un message de sécurité de base (BSM) fourni à partir d'un véhicule autonome, selon la présente invention, comprend une unité de communication, une unité de stockage et une unité de commande, l'unité de commande commandant l'unité de communication et l'unité de stockage de façon à accumuler le BSM ou la carte routière précise dans l'unité de stockage pendant une durée spécifique, configure un ensemble de données en calculant une variable indépendante à partir du BSM et en calculant une variable dépendante à partir de la carte routière précise, génère et entraîne un modèle de classification de section de route dangereuse en appliquant un algorithme XGBoost à l'ensemble de données, calcule l'importance pour chaque facteur de la section de route dangereuse, et effectue une analyse de facteur sur la section de route dangereuse sur la base de l'importance calculée pour chaque facteur.

    본 발명에 따른 정밀 도로 지도 및 자율 주행차로부터 제공되는 기본 안전 메시지(BSM)를 수신하는 위험 도로 구간의 요인을 분석하는 분석 서버는, 통신부, 저장부, 및 제어부를 포함하되, 제어부는, 기본 안전 메시지(BSM) 또는 정밀 도로 지도를 저장부에 특정 기간 동안 누적하도록 통신부 및 저장부를 제어하고, 기본 안전 메시지(BSM)로부터 독립 변수를 산출하고, 정밀 도로 지도로부터 종속 변수를 산출하여 데이터셋을 구성하고, 데이터셋에 대해 XGBoost 알고리즘의 적용을 통하여 위험 도로 구간 분류 모델을 생성 및학습하며, 위험 도로 구간의 요인별 중요도를 산출하고, 그리고 산출된 요인별 중요도에 기반하여 상기 위험 도로 구간의 요인 분석을 수행한다.
