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.

    Measuring vehicle lengths with a single loop - promising results
    District 7 of Caltrans has been conducting trials to see whether the use of a single inductive loop to measure vehicle lengths and so identify heavy trucks is feasible. So far, the results have been very promising, according to Lead Transportation Engineer Steve Malkson. Between them, the adjoining ports of Los Angeles and Long Beach, the US's two biggest, cover some 10,700 acres (43km2) and 68 miles (109km) of waterfront.

    Xerox’s Passenger Detection System has been trialled in California and compared with the state’s team of human counters giving some interesting results, as Colin Sowman discovers. Like others adopting high-occupancy and high-occupancy vehicle (HOV) lanes for congestion management, Caltrans has faced challenges with compliance in what has been effectively an ‘honour system’ with drivers trusted to set their tags correctly or comply with the multi-passenger requirement.
