Package: simu5g.mobility.trafficLightMobility

TrafficLightController

simple module

Defines the behavior of traffic light controllers in the simulation. It manages the states of the traffic lights (green, yellow, red) and handles the interactions with vehicles, thus influencing the behavior of a node implementing the TrafficLightMobility mobility model when such a node reaches the position of the traffic light. This module allows for the configuration of the duration of green-yellow-red cycles.

Used in compound modules

Name	Type	Description
TrafficLight	compound module	Simulates a traffic light in an urban environment. It incorporates a stationary mobility submodule to represent the fixed position of the traffic light, and a TrafficLightController submodule to model the traffic light's states (green, yellow, red) and its interactions with vehicles.

Parameters

Name	Type	Default value	Description
mobilityModule	string
greenPeriod	double	1s
yellowPeriod	double	1s
redPeriod	double	1s
startTime	double	1s
startState	string	"RED"	Do not use OFF or YELLOW for now
meanCarLength	double	4m
areaWidth	double	1m
bidirectional	bool	false

Properties
