IRD tyre sensors for safety and tolling

First published in ITS World Congress Preview - October 4, 2019

International Road Dynamics (IRD) is presenting two systems powered by the company’s VectorSense tyre sensor technology at this year’s ITS World Congress Singapore – the AACT and TACS.

AACT (Advanced Axle Classification for Toll) is a new system that provides more accurate single/dual tyre classification for tolling. It uses the tyre footprint information from the VectorSense sensors to provide detailed, real-time axle information that enables more accurate class information and verification of automatic vehicle classification (AVC).

TACS is an advanced screening technology that helps agencies to identify vehicles with tyre problems before accidents occur. It identifies vehicles with tyre anomalies – such as flat, missing or mismatched tyres – at highway speed. These anomalies can result in vehicle imbalance, reduced manoeuvrability, improper load distribution, reduced braking performance, poor fuel economy, and reduced tyre life.

Several enforcement agencies have successfully integrated TACS into their commercial vehicle e-screening systems and inspection programmes to identify vehicles with unsafe tyre conditions. IRD says these agencies have found TACS to be an effective method of identifying vehicles with tyre problems that are sufficiently serious to place vehicles out of service.
