Counting the traffic

About 40 billion kilometres a year are travelled on the nation's local roads and state highways. State Highway 1 in central Auckland is the busiest road in New Zealand, carrying more than 200,000 vehicles every day. Knowing about the number of vehicles using our roads enables us to plan more effectively - for today's environment as well as tomorrow's. For this reason, we operate a comprehensive 'traffic counting' programme that gathers information on traffic growth trends and the types of vehicle using the state highways.
