Oklahoma Department of Transportation recently carried out a trial of 69 International Road Dynamics’ (IRD) Tyre Anomaly and Classification System (TACS) powered by the VectorSense tyre sensor suite.

These systems provided Oklahoma with new, technologically advanced facilities that enabled cost effective screening of commercial vehicles for weight, credential or safety violations.

Over two days of operation, at two port-of-entry sites, a number of tyre anomalies were successfully identified by the TACS system. These included old and worn tyres, worn tyres adjacent to new tyres and flat or missing tyres. Of those vehicles identified as having anomalous tyres, 90 per cent had serious enough tyre defects to place the vehicle out of service.

With tyre anomalies being identified at a rate of one per hour of operation during the study, TACS offered an opportunity to efficiently target significant numbers of unsafe commercial vehicles using an automated process.

For the study, a custom interface displayed vehicle records sequentially in a similar fashion to IRD's virtual weigh station and operator workstation software, providing a side-fire photograph and the data obtained from the VectorSense tyre sensor suite, which included speed, number of axles, tyre width, lane position and highlighting of any tyres identified as anomalous. The simple layout effectively highlighted commercial vehicles with tyre anomalies.

    Q-Free’s Andrew Lees looks at regional characteristics and technology trends in the global Weigh-In-Motion market. The principles of Weigh-In-Motion (WIM) are well established. Data derived from vehicles passing over in-ground sensors can be interpreted for vehicle classification (axle counts and spacing) and positive identification (especially when linked to image capture) applications as well as to derive individual axle and gross vehicle weight (GVW).

Enforcing the compliance of commercial vehicles (goods vehicles over 3.5 tonnes and vehicles with eight or more passenger seats) on the UK’s roads is the responsibility of the DVSA (the Driver and Vehicle Standards Agency). The Department for Transport created the executive agency about 18 months ago by merging the Driving Standards Agency (DSA) and t
