Node closures
When two or more consecutive segments are selected when adding a real-time closure, it is possible to close each adjacent or included junction node to crossing or turning traffic. Junction nodes between selected segments will automatically be selected for closure, while nodes at the end of a range of multiple segments are not automatically marked for closure, but can be enabled. All turns through a closed node are prohibited. There is no partial-node closure function to select individual turns.
Editing or removing node closures
Node closures can be enabled or disabled from the closure tab when creating or editing a real time closure on an adjacent segment(s). Additionally, if all adjacent closures are removed for a junction node, the node closure(s) will also be removed. However, if any segment closure still remains adjacent to the junction node, the node closure will remain. The node closure must be disabled using the remaining adjacent segment closure to allow turns.
