Using The Opus RSD as a warning system increases the probability of finding an illegally tampered truck by 25x times, compared to a blind inspection.
In the spring of 2021, vehicle emissions in and around the port of Antwerp-Bruges were measured by Opus remote sensing devices. The measurements confirmed that a small group of vehicles is responsible for a large part of the pollutant emissions, due to defects or fraud. Remote sensing makes it easier for inspectors to deal with the problem. Using the Opus RSD as an alerting system, targeted and effective measures can be taken to prosecute offenders and improve air quality.
It is clear that the RSD generates a much higher effectiveness of (scarce) roadside inspection staff and equipment, compared to “blind” roadside inspections, without the use of the RSD for pre-selection of inspected vehicles.
