33 Delta has unveiled two important new features for the company’s LTL-M mobile retroreflectometer – an overhead camera and distance measurement instrument (DMI) – to further accommodate customer requirements.
The overhead camera is placed in the vehicle windscreen, providing a complete HD video of the markings and the road as seen by the driver. The video is stored for later review and is displayed synchronised with an overlay of the actual measurement data. The DMI is mounted on one of the vehicle wheels in order to provide accurate distance measurement on road stretches where the GPS may fail due to lack of satellite contact.

LTL-M provides continuous measurement of night visibility at traffic speed in full length and width of road markings. In addition, the system measures the daylight contrast, the width of markings and records the presence of road studs. The software supplied with the instrument generates easy-to-read reports on the measurements and can transfer data to Excel for further processing.
According to Kjeld Aabye, Delta’s marketing manager, “Even with the new features added, the LTL-M system continues to be very easy to mount, calibrate and operate and it provides data with accuracy in line with handheld instruments under all driving conditions.”

Global Navigation Satellite System (GNSS)-based positioning is unique among available positioning technology due to its universal coverage and low equipment cost. By measuring the distances between an unknown position (such as a vehicle), and at least three known positions (GPS satellites), the unknown position can be calculated in three dimensions (latitude, longitude, and

    Debating the future development of ANPR
    What future is there for automatic number plate recognition? Will it be supplanted by electronic vehicle identification, or will continuing development maintain the technology's relevance? In recent years, digitisation and IP-based communication networks have allowed Automatic Number Plate Recognition (ANPR) to achieve ever-greater utility and a commensurate increase in deployments. But where does the technology go next - indeed, does it have a future in the face of the increasing use of, for instance, Dedi
