What this guide does
This guide explains how to use intersection and swept path conditions to control specific turning movements at intersections in a Network Update Request (NUR). It helps you record where turns are allowed, prohibited, or limited by swept path requirements. These settings are used by the route planner to inform safe vehicle manoeuvres and access decisions.
Prerequisites
NHVR Portal account with Road Manager access.
Access to Network Management and an existing Network Update Request.
Relevant road segments at or near the intersection already selected in the NUR.

Step-by-step instructions
1. Open the NHVR Portal and log in using your Road Manager account.
2. Open the relevant network and create or open the Network Update Request that contains the intersection segments.
3. Use the selection tools to select the road segment immediately before the intersection where the turn condition applies.
4. Right click on the selected segment and choose the option to add a condition. This opens the standard conditions library.
5. Use the search field to locate one of the intersection or swept path conditions. There are three predefined intersection or swept path conditions that record different turn controls.
6. Enter any required parameters for the condition (for example, specifying which turning movements are allowed or prohibited, or swept path limits).
7. Click Add Condition to apply the condition to the selected segment in the NUR.
8. If additional intersection conditions are needed on the same segment, repeat Steps 4 to 7 for each one.
9. If you need to edit the intersection condition later, right click the segment and choose the option to view or edit the condition.
Tips and common issues
Apply intersection conditions on the segment immediately before the intersection, not on distant segments.
Remember that the condition only applies when a turn is being made. If a vehicle is travelling straight through the intersection, the segment is treated as approved.
Use swept path conditions where turning is permitted but only if vehicles comply with the defined swept path limit.
The Add Coondition button in the condition screen only saves details into the NUR; the live map is not updated until the NUR is submitted, approved and published.
Where to get help
Check your organisation’s internal guidance on applying intersection restrictions.
Contact the NHVR Network Management or Spatial support team if you are unsure which intersection condition to use.
