Abstract

The invention relates to a safety index system creation method based on bus driving safety. The safety indexes of the invention mainly relate to two types of indexes: a safety evaluation index and a safety risk index. Safety evaluation indexes are based on accident statistical data, accident occurrence frequency, accident casualties, accident property loss and other aspects are considered, and thedriving safety condition of an evaluation object in a past period of time is described objectively. The safety risk index is based on a safety evaluation index and other various safety attributes tofind out rules behind the safety of the traveling vehicle and quantitatively evaluate potential safety risks possibly existing in an evaluation object, and is an accident risk prediction index.

Description

technical field [0001] On the basis of comprehensive analysis of bus driving safety accidents, the present invention uses data mining to construct a safety management evaluation index system to comprehensively predict driving safety involving multi-dimensional objects such as people, vehicles, lines, fields and stations. Background technique [0002] At present, the bus company's assessment and management of the driving safety of the driving objects is basically based on a single assessment index such as the number of safe kilometers, and there is no systematic evaluation index. The internal management system of the bus company usually stores the following types of data: [0003] (1) Driver attributes: It mainly includes personal basic information of bus company drivers, data on physical health status, data on driving skills of drivers, and so on. The data structure of the driver attribute data is shown in Table 1 below: [0004] [0005] [0006] Table 1 [0007] (...
