Definition of variables coded.

Variable	Description	Coding value
GEN	Male	0
	Female	1
AGE	Young-age group (<30)	0
	Middle-age group (30–50)	1
	Old-age group (>50)	2
VT	Bicycle electric bike	0
	Scooter electric bike	1
NA	0 changes	0
	More than 2 changes	1
	1 change	2
AS	The speed of e-bike when it approached intersection at the beginning of amber light.	The real-time value
CCD	The distance of e-bike away from stop mark at the beginning of amber light.	The real-time value

AGE: estimated age group. Using estimated age group could be effective to extract e-bikers’ individual information. The groups were divided into young-age riders (<30), middle-age riders (30–50), and old-age riders (>50) reported by Wu et al. [7]. VT: vehicle type. Bicycle e-bike can ride the pedal to provide power for going forward, while the scooter e-bike’s power is only provided by electromotor. NA: number of acceleration rate changes. The number of times that acceleration rate changes from positive to negative, or from negative to positive.
