Relevant parameters used to calculate traffic flow

Parameter	Value	Description	Unit
*l_veh*	5	Vehicle’s average length	m
h	3	Minimum headway	m
*$k_{j} = \frac{1}{l_{v e h} + h} n_{l a n e}$**	500	The jam density	vehs/km
*k_m*	183.94	The density when the traffic flow reaches its maximum value	vehs/km
k₁ = 0.2 k_m	36.79	The density as free traffic state	vehs/km
K₂ = 0.7 k_m	128.76	The density as normal traffic state	vehs/km
K₃ = 2 k_m	367.88	The density as congested traffic state	vehs/km
