Be advised that your TrafficLand cameras are going to stop working after the tokens expire. This is not a new thing for me and I discovered this a long time ago.
TrafficLand manages cams for a number of states and puts expiring tokens in so that they can protect their revenue stream. If you can grab cameras that are managed and controlled by your department of transportation, you’ll have much better results.
Sometimes news outlets traffic cameras will work as well - when I used to live in Pennsylvania, I had a mix of DOT and Local news channel cams available. They still work too.
