DELTA's portable LTL-X Retrometer for measuring the retroreflection of road markings
199 Delta, which has introduced its brand new handheld RetroSign GR3 retroreflectometer for measuring the retroreflection of traffic signs, also offers a number of instruments for road markings.
The Danish company points out that as the median age of the average driver grows the importance of night-time visibility of pavement markings for traffic safety becomes even greater.

"Night-time visibility is determined by the retroflectivity of the pavement markings and therefore retroreflectivity is an important performance feature built into the roadways and is essential for efficient traffic flow and highway safety," says DELTA.

Its portable LTL-X Retrometer, for example, measures the retroreflection of road markings at a simulated distance of 30m according to CEN (European Committee for Standardisation) and ASTM (3930 American Society for Testing and Materials) standards.

The LTL-X has advanced new technology and an ergonomic design, and is the fourth generation retrometer based on the proven knowledge from the worldwide use of LTL2000 and its predecessors.

The retractable handle has an integrated display, and measurements and settings of road and user ID, line type, measurement averages, instrument status and languages are done at the touch of a button. Optional GPS values are shown, and the LTL-X is fitted with printer and wheels for easier operation.

    The joint proposal by 3F, the Danish trade union for the transport sector, and think-tank Kraka to replace vehicle registration fees with a GPS-based road user charging system is worth noting. According to 3F and Kraka, this would reduce congestion on Danish roads and generate savings worth €536 million (DKK 4 billion) for the nation’s finances. There is nothing new in this concept as such. Road user charging was proposed a few years ago for the UK and also for the Netherlands. But in the UK this proposal p

    Traffic signs and pavement markings have been in use for over 100 years to provide essential guidance and delineation of the travel path. In the ensuing years, the performance of these systems has been greatly expanded with the introduction of retroreflective optics to increase visibility at night and in wet night-time conditions.

    Pavement engineering specialist Dynatest has improved its best-selling falling weight deflectometer, allowing it to not just collect more data, but collect it faster. The Danish company said its FastFWD8002, which was unveiled at the Transportation Research Board annual meeting in Washington in January, is five times faster than the previous model. The FastFWD8002 collects 75% more test points per hour, meaning it can have around 45% less traffic exposure. The previous unit is upgradeable to FastFWD80
