The invention discloses an expressway section risk grade division method, which comprises the following steps of: obtaining road information of a specified expressway, and dividing and screening a test road section according to the road information; performing a driving test based on physiological indexes on the test road section, and collecting physiological data of a driver; carrying out noise reduction on the physiological data of the driver to obtain electrocardiosignal characteristic indexes, and carrying out clustering analysis on the electrocardiosignal characteristic indexes through a fuzzy clustering method to obtain risk levels based on the physiological indexes of the corresponding test road sections; and carrying out visualization processing on the risk grade and the electrocardiosignal characteristic index of each test road section by adopting a cloud picture algorithm to form a risk distribution diagram of the highway test road section based on the physiological indexes. Electrocardiosignals of a driver are adopted to represent the risk level of a road section, and clustering analysis is carried out on electrocardio indexes to divide the risk level of the road section into a high level, a middle level and a low level. And visualizing the highway section risk through a cloud picture algorithm, and determining the length of each risk level road section.

    本发明公开了一种高速公路路段风险等级划分方法,获取指定高速公路的道路信息,根据道路信息划分筛查出测试路段;对测试路段进行基于生理指标的驾驶测试,采集驾驶者的生理数据;对驾驶者的生理数据进行降噪后获得心电信号特征指标,通过模糊聚类方法对心电信号特征指标进行聚类分析,获得对应测试路段的基于生理指标的风险等级;将各个测试路段的风险等级和心电信号特征指标采用云图算法进行可视化处理,形成基于生理指标的高速公路测试路段的风险分布图。采用驾驶员心电信号来表征路段风险的高低,对心电指标进行聚类分析将路段风险等级划分为高、中、低三个等级。通过云图算法对高速公路路段风险进行可视化,并确定各风险等级路段长度。
