		*The data frame “ConnectionTrajectory-addGrpC” defines the trajectory for travelling through the
		conflict area of an intersection and connects e.g an ingress with an egress lane. The trajectory is defined
		by two or more nodes. The starting node overlaps e.g. with the node of the ingress lane towards the
		conflict zone. The ending node overlaps e.g. with the first node of the connected egress lane. See the
		example in clause G.8.2.5.
		“nodes” defines a list of nodes for the trajectory. It defines e.g. a geometric trajectory from an ingressing
		to a connected egressing lane and the X/Y position value of the first node of the trajectory is the same as
		the node of the ingress lane. The X/Y position of the last node is the same as the X/Y position of the first
		node of the egressing lane.
		“connectionID” defines the identifier of an allowed “maneuver” (e.g. ingress / egress relation). A generic
		Lane offers one or more allowed “maneuvers”, therefore the trajectory is reference to the related
		“maneuver”.
		Note: "Reg-GenericLane" allows providing up to 4 connecting trajectories. In case a lane has more than
		4 connecting trajectories, priority should be given to connecting trajectories of motorized traffic and
		complex manoeuvres.

		* @field regional / ConnectionTrajectory:
		The data frame “ConnectionTrajectory-addGrpC” defines the trajectory for travelling e.g. through the
		conflict area of an intersection. The trajectory is defined by two or more nodes. In the example in Figure
		G.1, the first node position of the trajectory (T2-1) is matching to the node of the ingress lane towards
		the conflict zone (L2-1), and the ending node (T2-6) and the first node of the connected egress share the
		same position (L6-1). Additionally, the data frame “NodeLink” (G.5.2.3) is used to define a clear relation
		between the trajectory endpoint and the connected lane point.

		towards the traffic light controller. The traffic light controller checks the request and
