Road signs in a flap

The Danish Road Directorate and Daluiso have developed a new type of road sign to make road works and maintenance tasks more efficient. Called 'swap signs', their function is to flap open/shut near road works, spring cleaning or grass cutting by contractors.

The 1845 Danish Road Directorate and Daluiso have developed a new type of road sign to make road works and maintenance tasks more efficient. Called 'swap signs', their function is to flap open/shut near road works, spring cleaning or grass cutting by contractors.

Importantly, the smart thing about these signs is that they are put in place, on the hard shoulder and central reservation, in the small hours when there is least traffic on the roads. They are deployed in neutral mode (grey background) and therefore no information is seen by the road user until work actually gets under way.

When the contractor arrives, the signs are activated by an internet-based system using a laptop. Only signs covering the area actually being worked on need be activated and, as the work progresses along the roadway, these swap signs can be flapped open and closed as need be.

As Daluiso points out, up to an hour of working time can be used by a contractor just setting up conventional signs. With swap signs, contractors can start work as soon as they reach the working area.

    Debating the future of in-vehicle systems
    Industry experts talk to Jason Barnes about the legislative situation of current and future in-vehicle systems. Articles about technology development can have a tendency to reference Moore’s Law with almost indecent regularity and haste but the fact remains that despite predictions of slow-down or plateauing, the pace remains unrelenting. That juxtaposes with a common tendency within the ITS industry: to concentrate on the technology and assume that much else – legislation, business cases and so on – will m

    US state of the art workzone safety
    The Texas Transportation Institute's Jerry Ullman talks about the state of the art in work zone safety in the US. Work zones are places where, perhaps more than anywhere else on the road network, mobility and safety are strongly linked. Historically, field crews and contractors wanted vehicles in work zones to be moving as slowly as possible, assuming that made conditions the safest for work crews. We are though starting to see a shift in such thinking with the realisation that excessive delays or slow-down

    As the ITS World Congress arrives in Copenhagen, Adam Hill finds out how Dynniq has been helping traffic flow – and CO2 reduction - in the Danish capital. Most of the time, ‘breathing easier’ is just an expression which indicates a metaphorical sigh of relief that something has worked out alright. But it can be literally true, too. Respiratory and other potential health problems which stem from pollution in the world’s increasingly urbanised environments have been well publicised and governments are
