This DF is used to combine/connect multiple physical lanes (i.e. within intersections or road

 segments). For signalized movements, the **connectsTo** data frame defines e.g. the relation between

 segments). For signalized movements, the **connectsTo** data frame defines e.g. the relation between

 ingress and egress lanes within an intersection. It describes the allowed manoeuvres and includes the

 ingress and egress lanes within an intersection. It describes the allowed manoeuvres and includes the

 link (**signalGroup** identifier) between the [**MapData**](#MapData) and the [**PAT**](#PAT) message. The data frame is also used
