基于熵权灰色关联分析的车辆行驶安全性评价

Evaluation of Vehicle Driving Safety Based on Entropy Weighted Grey Relational Analysis

为客观评价车辆行驶安全性,系统分析了影响道路交通安全的人、车、路、环境等因素,运用层次分析法构建车辆行驶安全性评价指标体系;运用熵值法确定各指标权重,建立基于熵权和灰色关联分析的车辆行驶安全性评价模型。案例分析表明,影响车辆行驶安全性因素的重要程度为驾驶员因素>车辆因素>道路因素>环境因素,模型评价结果与实际情况相符。

In order to objectively evaluate the safety of vehicle driving,the factors affecting road traffic safety are analyzed systematically,such as people,cars,roads and environment.AHP is used to to establish vehicle driving safety evaluation index system.The entropy method is used to determine the weight of each index,and a vehicle safety evaluation model based on entropy weight and grey correlation analysis is established.The case analysis shows that the importance of factors affecting vehicle driving safety is driver factor>vehicle factor>road factor>environmental factor,and the model evaluation result is consistent with the actual situation.
