This data is part of the strategic transport modelling undertaken for Urban Transport Crowding and Congestion, a supplementary report of the Australian Infrastructure Audit 2019. This project looks at historical data from 2016, and with that data it analyses the trends to predict what congestion will be like in 2031. [Network performance in Sydney, the Hunter and Illawarra](https://www.infrastructureaustralia.gov.au/urban-crowding-congestion-maps-sydney-network) shows interactive maps. The following resources are available, links will be provided that lead you directly to the current source of data. **Major Roads** \* Congestion on major roads during 2016 AM peak \* Congestion on major roads (projected) during 2031 AM peak \* Congestion on major roads during 2016 PM peak \* Congestion on major roads (projected) during 2031 PM peak **All Roads** \* Congestion on all roads during 2016 PM peak \* Congestion on all roads (projected) during 2031 AM peak \* Congestion on all roads during 2016 AM peak \* Congestion on all roads (projected) during 2031 PM peak
