Description:

The Traffic and Travel Data System API lets you access real time data on events / incidents that affect traffic conditions across the network of national highways in New Zealand.   An example of an event/incident could include road works, an accident, or weather related problems such as ice or snow.

Traffic and Travel Data System API services currently include:

·       Real time data on traffic conditions and congestion on national highways.

·       Estimates of the time required for vehicles to travel along sections of the state highway and arterial network.

·       Real time data on events and incidents, including weather and general warnings, that affect traffic conditions across the network of national state highways.

·       Static images from over 100 cameras across various parts of New Zealand.

·       Messaging displayed on Variable Message Signs (VMS) across various parts of New Zealand.
