I found a data series, the US govt publishes it - so I guess that makes it more reliable.
I was surveyed by Waka Kotahi a couple of weeks ago about my use of the traffic data and commented that Drury and Tawa were often late or ignored when roadworks occurred. They were both updated early this month so I already have their data for September and I have a preliminary update. However, have stuffed up my spreadsheet I am using to manage corrections to older data and need some time to fix it before publishing full updates - which also improves correlation to over 90% due to fixing roadwork data.
The data looks big, ie the NZ September quarter for trucking movements looks like yet another growth period.
I have added the USA truckometer I took from their data -
