Tools

Tools have been developed by multiple teams within the System Design and Delivery group, as can be found below.

Commonly used forms can also be quickly accesses through this section, by subject matter. 

If there's anything else you'd like to see in this section, please don't hesitate to get in touch.

For further information contact hip.feedback@nzta.govt.nz.

Forms

Commonly used forms that are used across the Highways group have been brought together to one easy-to-find place.

Systems

Easy to access systems useful to Highways and Network Operations.

Air quality screening model

The Transport Agency has a screening model for estimating air quality near roadways, which combines the contribution of the road together with the background air quality to arrive at a cumulative concentration.

Air quality map

This interactive map shows background air quality concentrations across New Zealand for two key pollutants – PM10 and NO2. The values shown exclude the contribution of nearby roadways and can be used with other tools such as the NZ Transport Agency screening model to assess the cumulative air quality effects of roading projects.

Construction noise calculator

NZS 6803 provides calculation methods for noise from construction activity making reference to BS 5228. Key elements of the calculations are described in the construction and maintenance noise and vibration guide.

Internal noise calculator

This calculator allows the internal noise level to be estimated based on the building construction and a specified external noise level. Noise is predicted through the wall facing the road, and optionally through the roof, windows and doors. Both the total noise level and the path contribution is displayed.

Noise barrier cost calculator

This calculator provides an estimate of the supply and installation costs of noise barriers, intended for use when comparing mitigation options during an assessment under NZS 6806. More accurate estimations should be made by specialists when required for project costing purposes.

Noise metrics tool

The interactive display explains the different metrics, and provides an indication of the value of each metric based on an input noise level and road type.

Noise screening tool

The road-traffic noise standard, NZS 6806, only requires mitigation to be considered in clearly defined circumstances. The purpose of this screening tool is to identify those project options where mitigation is definitely not required under NZS 6806. The screening assessment is made on the basis of noise levels with and without the project, which can be estimated with the road-traffic noise calculator.

Road traffic noise calculator

This calculator predicts road-traffic noise in situations without complex topography.

Transport-related air quality monitoring system

TRAMS is the transport-related air quality monitoring system which collates data from the Transport Agency and regional councils. This webpage allows users to view and export the summary air quality data by region and air pollutant, as well as the site metadata.
