A permanent solution

With up to 10 years of continuous measurements, the new FLEX can replace both loops, radars and manual counts.

A fraction of the cost

Without the need for roadside equipment or power, the total cost of establishing a permanent measurement location with the new FLEX is a fraction of that with loops or radars.


Real data

No rough counts or estimates of averages, the FLEX sensor delivers independently verified accurate per-vehicle data. Get counts, speeds and classifications you can trust.
