I would like some more information on how the speed and flow data is actually captured - is it at the specific site point location or an average over a section of road? What sensors are used to capture the speed? 


Thanks for the help!

I can confirm that all data within WebTris is from specific site point locations.

Thanks, are you able to provide more detail on how exactly the speed is captured and recorded?

That very much depends on the sensors themselves. We utilise both a number of sensory technologies, including induction loops embedded in the road and RADAR sensors on the roadside. As you might appreciate, each system gets the data in slightly different ways.
