Creating Stakeholder Value

Traffic performance notes Footnotes to slide 38: Traffic performance 2. Transurban improved the calculation of ADT during the June 2020 quarter. Traffic measurement involves the correlation of images and tags from detected vehicles. Reporting improvements enabled faster removal of duplicate trips, for example, where multiple tags are detected in a vehicle. The change to the calculation resulted in reported ADT reducing for some assets, by a maximum of 1%. ADT for prior corresponding periods was restated for comparative purposes. This ADT reporting change had no impact on revenue. 3.2022 ADT figures for Queensland assets are calculated excluding the period between 08:00 on 2 March to 23:59 on 6 March. Tolling was suspended during this time due to extreme rainfall events. 4. Proportion of large vehicle traffic as a percentage of total traffic for the March 2022 quarter. 5. Average tolled trip length was 12.9 kilometres for the March 2022 quarter on Westlink M7. 6. Average tolled trip length was 7.8 kilometres for the March 2022 quarter on M4. The New M4 Tunnels opened in July 2019. 7. Average tolled trip length was 9.2 kilometres for the March 2022 quarter on M8/M5 East. Disclosed average tolled trip length is adjusted to reflect the adoption of equalisation factors from the concession agreement which are designed to make tolls consistent across the M8 and M5 East motorways despite having slightly different asset lengths. 8. Transurban's proportional ownership of WestConnex increased from 25.5% to 50% through its equity interest in STP from 29 October 2021. 9. CityLink traffic reported as average daily transactions ('000). 10.95 Express Lanes concession includes the 395 Express Lanes which opened in November 2019. 11. Transurban's ownership of Transurban Chesapeake reduced from 100% to 50% from 1 April 2021. Transurban 45
