Embodiment Construction

[0039] The present invention is described in further detail below in conjunction with accompanying drawing:

[0040] like figure 1 As shown, the method of the present invention comprises the following steps;

[0041] Step 1. Establishing a GPS database: use the vehicle driving data collected by the vehicle-mounted GPS device as the GPS database. Vehicle driving data includes vehicle license plate number, latitude and longitude, vehicle speed, direction, location address and time stamp.

[0042] Step 2. Data processing: According to the data in the GPS database, 17 risk exposure factors were deduced, and these 17 risk exposure factors were standardized, as shown in Table 1.

Abstract

The invention discloses a dangerous cargo truck survival probability and danger probability prediction method. The method comprises the following steps that 1, taking vehicle driving data collected byvehicle-mounted GPS equipment as a GPS database; 2, setting a plurality of risk exposure factors, and performing standardization processing on the risk exposure factors to serve as samples; Randomlydividing the data into modeling data and verification data according to a ratio of 8: 2; 3, calculating basic variables of the risk exposure factors in the step 2 by utilizing factor analysis based onprincipal component analysis, extracting the basic factor variables x1, x2, x3 and x4, and further generating a survival function and a danger function; And 4, adopting the survival function and thedanger function in the step 3 to calculate the survival probability of the vehicle at the specific mileage and the accident probability at the specific mileage, and a calculation result is fed back toa driver for early warning. Danger is evaluated before the dangerous cargo truck goes out, early warning prompt is carried out in advance, and the occurrence rate of traffic accidents is reduced.

Description

technical field [0001] The invention belongs to the technical field, and relates to a method for predicting survival probability and danger probability of dangerous goods trucks. Background technique [0002] In 2014, 2015 and 2016, there were 3,744, 3,598 and 3,864 fatal accidents involving large trucks, according to the Federal Motor Carrier Safety Management Report. Truck drivers are at greater risk than other jobs and are 12 times more likely to die than the average American worker. These alarming facts show that trucks are a major contributor to fatal motor vehicle crashes, causing significant loss of life and productivity every year. As a type of trucking, commercial dangerous goods transport (CDGT) road traffic continues to take off around the world at a national or international level. [0003] Two factors may have a significant impact on the safety of CDGT. The first aspect is core driver and vehicle safety, the safety features of the driver and vehicle themselve...
