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.”

Around 22% of the fatalities are pedestrians, 15% will be motorcycle riders and 8% cyclists. So despite the improvements in road safe

    Colin Sowman discovers how the latest systems can boost productivity and reduce conflict in parking enforcement. Parking enforcement is something of a ‘Cinderella’ service for local authorities: while necessary to keep the roads open and the traffic flowing, it is an expensive operation and can be loss-making. It is also labour intensive and parking enforcement officers are routinely verbally abused and sometimes physically attacked. Some authorities are now looking to automate parking enforcement in orde
