Table 1

Decision variables.

	Arrival time of tram m at node e
	Departure time of tram m from node e
	The original green start of lane group j during phase n in cycle k at intersection i
	The original green end of lane group j during phase n in cycle k at intersection i
	1, if a TSP measure is taken in cycle k at intersection i; 0, otherwise
	1, if green extension/phase insertion/early green is taken in cycle k at intersection i; 0, otherwise
	Extra green time for a TSP action in cycle k at intersection i
	The end time of green extension in cycle k at intersection i
	The start time of phase insertion in cycle k at intersection i
	The end time of phase insertion in cycle k at intersection i
	The start time of early green in cycle k at intersection i
