Embodiment 1
[0036] A method for predicting the severity level of traffic violations based on Bayesian networks, comprising the following steps:
[0037] S1: Determine the variables of the Bayesian model;
[0038] S2: Establish a Bayesian model and train the model.
[0039] Further, the specific process of the step S1 is:
[0040] According to the analysis of the driver's gender, age, driving experience, time period of illegal incidents, types of illegal vehicles, vehicle attribution and severity of traffic violations, these factors are determined as variables of the Bayesian model, a training set and parameters in the training set can be expressed as figure 1 Shown:
[0041] X={G,A,D,T,W,V,O,L} (1)
[0042] in:
[0043] G={0,1} means gender, 0 means female, 1 means male;
[0044] A={0,1,2,3,4,5} means age, where 0 means 18-20 years old, 1 means 21-30 years old, 2 means 31-40 years old, 3 means 41-50 years old, 4 means 51 years old -60 years old, 5 means 61 years old and above;
