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

Table 6

Comparison of risk classification models (binning data).

	LRbox	NNbox	RFbox	SVMbox	Average
AUC0-1·2	0.832	0.798	0.796	0.798	0.806
IR (%)	11.25	7.72	3.39	13.82	8.93
AUC1-2	0.850	0.823	0.833	0.829	0.834
IR (%)	8.45	5.71	32.74	6.27	12.28

Note 1: LR_box, NN_box, RF_box, and SVM_box represent LR, NN, RF, and SVM models using binning data, respectively. Note 2: AUC_0-1·2 and AUC_1-2 represent the AUCs for collision-free and collision, and severe collision and general collision incidents, respectively. Note 3: IR represents the increase in the AUC compared with the corresponding nonbinning data model.
