2198 Westermo's DDW-120 Ethernet extender allows existing twisted pair cables to be used to establish a high-speed remote connection between two Ethernet networks. The company claims this is an easy-to-install alternative to optic-fibre or radio systems when linking remote Ethernet networks.

The device employs a transient blocking unit on each line interface to provide both over-current and over-voltage protection, allowing the line to handle indirect lightning strike transients, power induction and short circuit problems.

The DDW-120 uses twisted pair cables rather than expensive optical fibres or radio links. This plug-and-play unit covers many applications, offering data rates from 192Kbit/s to 5.7Mbit/s in both directions over distances of up to 15km (10 miles).

    David Crawford parallel parks with innovations in two continents. Surveys of US cities indicate that drivers searching for parking can account for up to 37% of all urban traffic congestion. A 2011 study by IBM of 20 cities around the world found that nearly six out of ten drivers had abandoned their search for a parking space at least once; while motorists generally spent on average 20 minutes looking for a sought-after spot.

    Traffic engineers can use the latest advances in vision technology to streamline and enhance traffic management. The idea of using one camera to perform all functions at an intersection is attractive to authorities for many reasons and camera supplier Gridsmart says it can make this happen. Its Bell Camera offers a horizon to horizon view that includes the centre of the intersection where vehicles, bicycles and pedestrians cross paths and it can be used for traffic light actuation, traffic data collection a

    A new generation of ITS equipment is helping road authorities get to grips with cycle safety – and not a moment too soon as Colin Sowman discovers. Cyclists - remember them? Apparently not. At least not according to the OECD 2013 report Cycling, Health and Safety which contains the statement: ‘Cyclists are often forgotten in the design of the road traffic system’. Looking through the statistics that exist (each country appears to compile them differently) it is not difficult to see how such a conclusion cou
