Cost Efficiency 3 - Asphalt Resurfacing (Length & Area)

Filters
Measure Description
Important Links

The aim of this measure is to demonstrate the total length and area of asphalt resurfacing undertaken over the selected year by classification, for your network.

The comparative graph shows the percentage, by area of network, of asphalt surfacing renewed over the selected year by your network, Peer Group , Region and the Nation .

The surface data is taken from the Road Section Surface table or the Surface Structure table which is being filtered by:

Surface Materials - Asphalt
Materials Surface Function - Reseal and Second Coat
Asphalt Surface Structure Set - Top Surface
Functions Surface Sectioning - by Road Section

The Lane Kilometres are assumed to be the length of the Seal * number of Lanes from the Road Section.

If the Sealed Area is recorded then this will be used. The Sealed Area may or may not reflect the Width or Length of the Road Section. If the Sealed Area is not recorded, then it will be assumed that the Seal is for the full width of the Road Section and the Area of the Seal will be calculated from the Seal Length * Road Section Width.

The Percentage by Area total is calculated by summing the One Network Road Classification (ONRC) , then given as a percentage of the total area.

The classifications come from the Road Section table and ONRC Category table.

The data is grouped by Financial Year beginning 1 July.

Transport Insights is developed by Road Efficiency Group Te Ringa Maimoa (REG).

The Transport Insights home page shows a map with key performance indicators for all Territorial Local Authorities. Click each indicator to see the nationwide results for that indicator on the map.

Transport Insights includes a range of reporting options via the menu on the left:

Road Controlling Authority (RCA) Performance Dashboard,
One Network Road Classification (ONRC) Performance Measure reports,
One Network Framework (ONF) Performance Measure pages,
Network Characteristics reports for ONRC and ONF showing network breakdowns,
Data Quality Dashboard and metrics results.

You can look at results for different Councils, regions etc by selecting the one you want from the dropdown list in the orange header. You will see National by default if you are not logged in.

There are also a range of Help pages which tell you about using the site and the information available.

To select an ONRC Performance Measure report, click the ONRC > Reports item in the menu.

ONRC reports for your Road Controlling Authority (RCA) are available under headings: Safety, Resilience, Amenity, Accessibility, Cost Efficiency, and Other.
ONRC reports for your Region are available under headings: Safety, Amenity, Cost Efficiency, and Other.

Click on the headings to view the reports under that heading for your RCA or Region.

Click on the report title for your RCA/Region, or click on Compare Networks to the right of the title. The report will show the data for your network and comparisons, for example your RCA alongside its peer group, region and the nation.

Adjust report parameters by clicking the Select Networks, Classifications, Urban/Rural, etc options in the Filters tab, then click Refresh View. Export the report to Excel and PDF files using the Excel and PDF buttons.

In the other tabs read more details in the Measures Description tab, visit Import Links, read any Data Validation messages and Data Quality reports.

You can filter State Highways in comparative reporting by:

Corridor
Regional Council
District Council (TA)
NOC (Network Outcome Contract)

You can compare sections of the State Highways network against each other, filtered by Road Corridor / Region Council / District Council / NOC (up to 6 filters at a time).

Territorial Local Authorities are grouped into Peer Groups with other Councils that have similar proportions of urban and rural network. See the Help pages for more information on which RCAs are assigned to which Peer Groups, and also the Regions that the RCAs are in.

You can quickly select all the RCAs in your Peer Group for a comparative report by:

going into Select Networks,
clicking Peer Groups, and
clicking the 'Add all RCAs to Selection' button beside your peer group.

Within the ONRC reports, export the full page by clicking on the PDF or Excel button once you have opened the report.

Within the ONF pages, click the symbol with three horizontal lines at the top right of each graph and choose the format to download for that graph. There is also a link at the top right of the page to download the full dataset for that page.

For more information see our Help pages.

Road Efficiency Group Te Ringa Maimoa (REG) is working hard to help the sector improve the quality of New Zealand’s transport related data, to support evidence-based decision making and lift investor confidence through robust data.

REG has developed an improvement programme to help RCAs address data quality issues. Read more about the improvement programme in the REG website.

See the Transport Insights Help pages for more information about the Data Quality screens and how the score is calculated.
