Hello,
we have a real-time demo, eg. in this video

that we now want to add simple analytics:

1. show speeding vehicles, eg. faster than 70 mph,
   eg. something in their icon

2. show an alarm if any vehicle is stopped for more
   than a threshold time period, eg. 5 minutes. It means
   that either there’s bad traffic, or some break down.

Thanks for any pointers.
