WASHINGTON DC: To avoid serious risk of road traffic and accidents, a team of researchers has proposed an innovative laser technology to deal with dangerous icy roads in winter.

According to researchers, snow plow can now look smarter by equipping normal salt-spreading trucks with an "artificial intelligence" device, to get rid of a dangerous, invisible killer 'hydrohalite' on icy roads.

The experts have detected a problematic substance known as 'hydrohalite', which forms on icy roads that have already been treated.

Hydrohalite is normally left unremoved, as it does not respond to the conventional de-icing method of road surface salting and once formed, repeated salting will not remove it.

It is invisible to the naked eye, and can form on both roads and pavements, presenting a serious threat to all road users if left untreated.

Study author Dr Rolf W. Berg from the Technical University of Denmark's department of chemistry said that as the nights get colder, people will again see the widespread use of salt to de-ice roads. However, this method will not work when hydrohalite has been formed, exposing the public to a serious risk of road traffic accidents.

"Equipping salt-spreading trucks with Raman detectors - essentially small boxes which would sit underneath the vehicles - would be a relatively straightforward solution, potentially reducing the number of road traffic accidents and even saving lives," Berg added.

The team recreated the conditions under which the hydrohalite substance forms.

They discovered that hydrohalite can be easily detected by using Raman instruments, small devices which can identify the structure of a molecule and the presence of a substance.

Since ice and hydrohalite are very different structurally, Raman instruments fitted with lasers could therefore be installed in salt-spreading trucks and snow ploughs, allowing drivers or an automated system to identify the most appropriate method to make the ice melt.

If hydrohalite was found, the driver could then switch to a more appropriate de-icer, such as one mixed with sand and gravel, to ensure the road is completely clear and safer for road users.

The research is published in Applied Spectroscopy Reviews.
