Traffic monitoring information is fundamental for the management of the state highway network. The measure of the traffic demand, imposed on the network, enables the NZ Transport Agency to make well founded decisions across its business. Learn more how traffic is monitored on the state highways. See also state highway traffic volumes by year (traffic data booklets).

The state highway system accounts for about 12% of New Zealand’s roads and around half of the 40 billion vehicle kilometres New Zealanders travel each year. Motor vehicles travelling on roads emit an array of air pollutants which can contribute to harmful effects on human health and smog formation. The Transport Agency is committed to being socially and environmentally responsible and has specific objectives in its state highway environmental plan for improving air quality, including:

Understand the contribution of vehicle traffic to air quality. Ensure new state highway projects do not directly cause national environmental standards for ambient air quality to be exceeded. Contribute to reducing emissions where the state highway network is a significant source of exceedances of national ambient air quality standards. In 2007, the Transport Agency began a national monitoring programme to determine relative levels of vehicle pollution across the state highway network.
