The combination of Vaisala’s TempCast and Wx Horizon solutions is an easy and affordable way to get accurate road weather measurements from challenging locations.

TempCast is a wireless, pole-mounted sensor that measures air temperature, humidity and pavement surface temperature without ever touching the pavement. With built-in connectivity and power, TempCast can be installed almost anywhere, turning an ordinary road into a smart road. It brings additional observational value from locations between existing road weather stations, that were previously hard to measure. It can also be used to build entirely new networks that were not feasible before.

TempCast – a self-powered, wireless NB-IoT unit - is the latest IoT-based sensor in Vaisala’s offerings and comes with a three-year battery lifetime. Meanwhile, Vaisala GroundCast, an in-ground IoT-based sensor that measures pavement temperature from different depths, as well as the road surface state, was introduced last year.

Both TempCast and GroundCast connect to Wx Horizon, Vaisala’s subscription-based weather hazard impact portal that delivers visualisations, alerts and insights on current and future road conditions.

Vaisala says that its weather and environmental technologies are routinely used to develop creative, new applications in the areas of traffic management, winter maintenance, advanced automotive applications and beyond.

    Cornwall's Saltash Tunnel on the A38 trunk road is a crucial link between the county, and the neighbouring county of Devon, and is used by 38,000 motorists per day. Opened in 1988, the 410m long road tunnel in south-west England, is a single bore with three traffic lanes, and is part of the tidal flow system across the three-lane Tamar Bridge. The central lane has a speed limit of 30mph (48km/hour) and operates as a reversible lane to cope with holiday and rush hour traffic.

    The demand for bitumen additives is set to increase. Kristina Smith reports on some of the companies who are preparing to meet that increased demand. The variation in quality and composition of bitumen around the world is something that has been well-documented in these pages. Processing technologies for crude oil are changing, the way bitumen is traded is changing, and the final result can be a product that may not be all it seems – or huge variations from one shipment to another. Help is at hand, however,

  • A breakthrough in the horizontal reuse of PA (porous asphalt)
    May 12, 2016
    An ambitious objective has led to significant steps in the reuse of PA (porous asphalt). While the market incidentally produces PA with a maximum of 30% of recovered raw materials, BAM has introduced its own innovations, enabling more than 90% of raw materials to be reused. And this year, subsidies from the European Commission will enable the LE2AP demonstration project to be constructed: one kilometre of sustainable PA. Large-scale production is also being developed.
