What is the Transport Noise Data?

This dataset represents a strategic national 3D model designed to quantify the acoustic footprint of road, rail, and aircraft activity across Australia. Representative of the year 2018, this dataset was built using sophisticated environmental noise modeling software (SoundPLAN) to calculate exposure levels for over 15 million buildings. Unlike previous localised studies, this model integrates diverse data streams, including GPS “probe counts” for 3.47 million road segments, 3D flight trajectories from radar tracking, and national rail timetables, while accounting for physical variables like terrain elevation and building heights.
