bool  removeGeometryNodes

Removes "unwished" nodes.

Removes nodes if a) no incoming/outgoing edges exist or b) if the node is a "geometry" node. In the second case, edges that participate at the node will be joined. Whether the node is a geometry node or not, is determined by a call to NBNode::checkIsRemovable. The node is removed from the list of tls-controlled nodes.

Parameters
[in,opt.changed] dc The district container needed if a node shall be removed
[in,opt.changed] ec The edge container needed for joining edges
[in,opt.changed] tlc The traffic lights container to remove nodes from
[in,opt.changed] sc The pt stops container to update stop edges
