An Improved Critical-Edge Model for Finding Optimal Contraflow Links Considering the Influence of Intersections

Table 1

The basic information of road links.

Directional links	Free-flow speed; vf/(km/h)	Minimum speed vmin/(km/h)	Length; L/m	The number of lanes; Lan	Capacity cij/(pcu/h)	Jam density; kj/(pcu/km/lan)
