Table 4

Toll fee structure for the revised toll-by-weight policy.

Weight type	Weight scenario	Fee rate (CNY/km)
Wlegal	Wlegal ≤ 5 t	Rlegal = 5 × b
	5 t < Wlegal ≤ 10 t	Rlegal = 1.25 × Wlegal × b
	10 t < Wlegal ≤ 20 t	Rlegal = [1.1 × 10 + (Wlegal − 10) × (7/6 − Wlegal/60)] × b
	20 t < Wlegal ≤ 40 t	Rlegal = [10 + (Wlegal − 10) × (370/300 − 7 × Wlegal/300)] × b
	Wlegal > 40 t	Rlegal = [10 + (Wlegal − 10) × 0.3] × b
Wexcess	Wexcess ≤ 0.3Wlimit	R = Rlegal + (G − Wlimit) × 0.4 × b
	0.3Wlimit < Wexcess ≤ 0.5Wlimit	R = Rlegal + [0.3Wlimit × 0.4 + (G − 1.3Wlimit) × 4] × b
	0.5Wlimit < Wexcess ≤ 0.8Wlimit	R = Rlegal + [0.3Wlimit × 0.4 + 0.2Wlimit × 4 + (G − 1.5Wlimit) × 5] × b
	Wexcess > 0.8Wlimit	R = Rlegal + [0.3Wlimit × 0.4 + 0.2Wlimit × 4 + 0.3Wlimit × 5 + (G − 1.8Wlimit) × 6] × b
