National Street Intersection Dataset

Callpoint Spatial has been generating this dataset quarterly since 2009.  We use the PSMA Transport & Topography dataset as our source data.

This dataset (also known as the Street Junction data, Cross-Street dataset, Intersecting Street or Street Corner dataset) is a comprehensive dataset of street intersections for each State across Australia.

The dataset can be used for instance to find all the intersections of a particular street in a given locality.

Extracting 4-way and T intersections

Callpoint’s Street Intersections dataset can also be queried to identify n-way intersections.  This can find application in traffic management and logistics.
