The Twister, from German manufacturer 8324 Traffic-lines, represents an alternative method for removing road markings. Traffic-lines says that its environmentally friendly method uses nothing but water.


The system attacks the relevant area with a high-pressure water jet and then immediately sucks the used water back up together with the removed material. It uses a highly efficient suction action which means that there is no water residue left on the cleaned-up road surface.    

Traffic-lines says the machine is unique in the market because there is no accumulation of water inside the suction hood. This enables a very noticeable increase in performance compared to conventional hydro-blasting with the same pump performance.

The Twister also has another advantage: after removing the markings, the machine leaves the road surface dry while producing significantly less siltation. The result is better adhesion of newly applied markings, which increases durability for the markings.

Traffic-lines also makes ex 1.0, a patented, liquid marking removal additive that is biologically degradable.

Traffic-lines ex 1.0 helps loosen markings from surfaces without attacking those surfaces so that the old markings can then be removed by hydro-blasting. The process leaves as little residue as possible while minimising surface damage. Removing markings with the aid of traffic-lines ex 1.0 involves hardly any elution of bitumen and the aggregate is not exposed.

    A new generation of video compression can lower transmission costs of data and make streaming from mobile and body-worn cameras a reality, as Colin Sowman discovers. Bandwidth limitations have long been the bottleneck restricting the expanded use of video streaming for ITS, monitoring and surveillance purposes. Recent years have seen this countered to some degree by the introduction of ‘edge processing’ whereby ANPR, incident detection and other image processing is moved into (or close to) the camera, so

The use of rivers and canals for moving freight is a well-established mode in North Western Europe, where it can take advantage of an intensively developed network. In the Netherlands, 40% of the total volume of goods transported internally goes by water; the figure for Flanders (the neighbouring Dutch-speaking region of Belgium) is 11.5%.
