With 5.5 million people calling Sydney home, growth in Australia’s most populous city shows no signs of slowing down. For residents and tourists alike, moving around Sydney quickly and efficiently is a priority.

Planning for Sydney’s transport requirements provides both challenges and opportunities. The arrival of new technology and rapidly changing mobility options has made the transport planning process particularly complex. The right model, data and careful analysis can guide these decisions and provide greater confidence about the impact of a policy or investment decision.

Key features 

Public transport crowding

The Zenith model includes the costs of over-crowding on public transport, affecting travellers’ choice of destination, mode, route and stop. As a result, the model can be used to assess the likely demand and economic benefit of capacity-increasing transit projects.

Toll choice

The Zenith model has an unrivalled track record of accurately predicting toll road patronage in Australia.

Fully multi-modal

Zenith models consider numerous access modes to transit, including walking, park ‘n’ ride and kiss ‘n’ ride. This feature is essential, considering the importance of these modes in Australia’s sprawling cities.


All Zenith models include a minimum of three periods.

Disaggregate travel zones

All Zenith models can be run at sub-SA1 travel zones. This is essential in transit studies where accessibility to the transit system is a major factor.

Disaggregate travel market segmentation

Zenith models include data showing travel by residents and visitors. Results are segmented by numerous journey purposes and car ownership levels. In addition, freight movement can be measured.
