Heterogeneity in the Driver Behavior: An Exploratory Study Using Real-Time Driving Data

Table 10

Cluster characteristics of data-driven critical driving patterns.

Driving pattern	Performance feature	Mean	SD	Upper limit (Mean + SD)	Lower limit (Mean - SD)
Aggressive acceleration		0.26	0.06	0.32	0.20
Aggressive braking		0.33	0.08	0.41	0.25
High-speed		61.97	11.68	73.66	50.29

Note: ^∗The units of accelerations are in “g” (9.8 m/s²); ^∗∗ the units of speed are in “kmph”
