The growing need for closer management of the road infrastructure brings increased demands for accurate information on vehicle type and speed. Whilst temporary classifier units can offer snapshots of road network usage, only permanent installations allow the complete picture to be seen.

Siemens’ Sieclass vehicle classifier is an extension of the well-proven Remote Monitoring OMCU and offers the capability to continuously log a wide range of road usage parameters. Up to eight logging channels are available, each able to record flow, occupancy, speed, headway and class – based on 14 configurable length parameters. Where accurate vehicle counting is required in multi-lane environments, full N+1 counting facilities are also available.
