	A directed road link,
	Set of reservation road links,
	Set of common road links,
	Set of O-D pairs
	An O-D pair,
	Set of paths from origin to destination
	A path from origin to destination,
	Traffic flow on the link
	Optimal reservation volume
	The admissible state of the request of the vehicle to enter the link
