Selected independent variables Influencing factors Selected independent variables Road Location of the car in road sections Road safety class 47 Road surface condition Environment Visual state Transport vehicle Vehicle condition Driver Driver status Study. In this paper, in order to establish a predictive model of the conflict points of a road accident, we define a dependent variable that represents whether the area of the conflict point of a road accident, if there is one, is y=0, otherwise y=1. Table 2. Description of independent variables Independent variables Descriptions Code X 1 Location of the car in road sections 0=non-conflict zone 1=conflict zone X 2 Road safety class 0= high-security road 1=low-security road X 3 Road surface condition 0=good 1=bad X 4 Visual state 0=good 1=bad X 5 Vehicle condition 0=good 1=bad X 6 Driver status 0=good 1=bad Results. All 6 factors can be used in logistic regression, and the results of the model will be summarized in Table 2, where B - the estimates of the parameters of the regression equation; S.E - the standard deviation of the regression coefficients reflecting the discrete degree of data, Wald - the value of the Wald criterion, which can be used to check the significance of the regression coefficients; the larger the value, the greater the role of the corresponding independent variable; df - the degree of freedom of arguments, and Sig - the level of significance. From the table. 3 it can be seen that all 6 independent variables have a significant impact on the dependent variable, so they should be used when building a logistics model. Download 0.91 Mb.
