ONRC

The NZ road industry has agreed to implement One Network Road Classification (ONRC) on all roads in NZ. So every RCA is required to classify each of the roads in their network according to ONRC criteria. Press Details below to find out more.

RAMM and the ONRC Process

RAMM Software Ltd (RSL) has created a special ONRC version of RAMM GIS that enables councils to classify their roads at the press of a button so to speak. Naturally, councils will then use their local knowledge to fine tune the result.

See the ONRC Process

The following video is a step by step demonstration of how you will use the ONRC version of RAMM GIS to classify your roads.

An Introduction to ONRC
This short video will demonstrate how to classify your roads.

The following short clips show individual steps in the ONRC process. You would watch these if after watching the introduction above and then starting the road classification you forgot an aspect of the process.

Generate the ONRC Data

Generate the ONRC Data

You can generate your ONRC data at the press of a button. It takes a very short time.

Layer the ONRC Data on the Map

Layer the ONRC Data on the Map

Once you have generated your ONRC data you will want to see the data layered on the map. There is a special layer created so that you can do this.

Use the Map Legend

Use the Map Legend

When you first see the colourful ONRC data display, the meaning of the colours will not be obvious. You open the map Legend to understand the display. The Legend dynamically displays the different layer settings.

View and Solve Data Issues

View and Solve Data Issues

You should check and amend your data before you add the ONRC Criteria. If there are data errors you need to find and fix them.

Regenerate Your ONRC Data from Scratch

Regenerate Your ONRC Data from Scratch

If you have had to fix many data errors or if you update your traffic counts and estimates, you will want to regenerate your ONRC data. This will delete any Criteria and Overrides you have added. So you would want to do this early in the process if at all.

Select Roads and Carriageways

Select Roads and Carriageways

When you are adding your Criteria and Overrides you first select the Roads or Carriageways. Watch this video to see your selection options.

Add a Criterion

Add a Criterion

You add Criteria to roads and carriageways which have the appropriate characteristics.

10

Add an Override

Add an Override

There may be roads or carriageways which you believe should be categorised differently from the one the tool has given them. In this case you raise or lower the category by Overriding it.

Remove a Criterion

Remove a Criterion

If you have added an ONRC Criterion to a road or carriageway in error, you remove it.

Reset a Category

Reset a Category

When you see the changes you have made to your ONRC data, you might want to have a second attempt at categorising roads and carriageways. In this case you reset the Category and start again.

If you want to view a single Category on the map or to compare two or more Categories you can add a large number of optional analysis layers.
