The survey and submissions closed at 5pm on 31 May 2024 and the Guide to Transport Impact Assessment has now been updated and published.

The Guide to Transport Impact Assessment

The Guide to Transport Impact Assessment (GTIA) was published in 2024, after extensive engagement with industry professionals.

The GTIA provides technical guidance for transport practitioners, consent authorities, local councils, and specialist consultancy firms, who work with development applications. The purpose of the guide is to support the preparation and review of transport impact assessments.

Key updates include:

• consideration of the wider multimodal transport network,
• context-based parking rates,
• updated trip rates,
• guidance for travel demand management
• guidance for transport impact statements.

Feedback received on the draft Guide

A draft version of the Guide was released between 20 March to 31 May 2024 for industry consultation. Transport for NSW received great interest. Feedback was considered from three webinars with over 500 attendees and two in-person events with over 120 attendees. Additionally, we had over 6,000 visits to this webpage and over 600 downloads of the documents. Transport for NSW were pleased to receive over 75 submissions and survey responses. Overall, you told us that the draft Guide was a major improvement on the outdated 2002 guidance and provided constructive feedback to make it even better.

Feedback from industry has informed updates and refinement of the Guide and the development of our forward program of improvements. Details on changes made and the future work program can be found in the Release Note.

Next steps and continuous improvements

The Guide was successfully developed and published following strong collaboration across industry over the past few years to build clearer, more consistent best practice guidance.

Transport for NSW welcomes continued feedback through the project mailbox (GTIA@transport.nsw.gov.au) and will continue making periodic updates so that the Guide remains relevant and useful into the future.
