Notations—parameter and symbol definitions that are used in the algorithms and the figures.

Symbol	Description
	The number of roads at the intersection (default: 4)
	The number of lanes on the road r.
	Minimum time to open a road (default: 3 sec)
	Maximum time to open a road, to prevent the starvation of roads having few vehicles
	Maximum time for a red signal. This is very important to avoid starvation
	Transition time to change the open road state from open to closed. Equivalent to the yellow light signal
	Total estimated time to service one round of all the roads
	Time at which the road r became red
	Time since green light is on
	The currently open road (similar to the green light)
	A timer for the open road (green timer)
	Current time
	Road heading direction
	The intersection stop line for the road r
	Distance from the current location of vehicle i on the road r to the intersection stop line
	Maximum distance from the intersection stop line on any road to consider any vehicle in the vehicle count. Typically, this value is set to 400 meters
	Number of vehicles queued on the road r within a distance from the intersection
