Individual Driver Crash Risk Classification Based on IoV Data and Offline Consumer Behavior Data

Table 8

Comparison of severe collision and general collision risk classification models (binning data).

Dependent variable	LRbox		NNbox		RFbox		SVMbox
	AUC	IR (%)	AUC	IR (%)	AUC	IR (%)	AUC	IR (%)
Basic features	0.800	—	0.729	—	0.785	—	0.778	—
Basic features + turning specific	0.779	−2.60	0.725	−0.58	0.761	−3.07	0.779	0.12
Basic features + consumer behavior	0.861	7.62	0.808	10.80	0.830	5.67	0.833	7.04

Note 1: LR_box, NN_box, RF_box, and SVM_box represent LR, NN, RF, and SVM models using binning data, respectively. Note 2: IR represents the increase in the AUC compared with the basic feature-based model.
