A Heriot-Watt spin-out company is using smart technology to help safeguard Scotland's roads and possibly bring an end to pot-holes.

Gritting lorries are a familiar sight at this time of year but maintaining adequate salt supplies remains an ongoing battle for local authorities. In the UK alone, it costs around £150m to spread more than 2 million tonnes of grit onto the UKs motorways, trunk roads and main roads.

MicroSense - Technologies - Ltd - MTL - Sensing

Now the award-winning MicroSense Technologies Ltd (MTL) has developed a state-of-the-art sensing system to ensure an equal spread of grit across road surfaces. Measuring at around the size of the average mobile phone, the device can be fitted to a gritter and uses advanced data analysis and bespoke radar sensing to detect how much de-icer salt is already on the road.

This information is instantly fed-back to an on-board computer, allowing the vehicle to automatically adjust the amounts of grit required, whilst also recording the condition of the road surface.

MTL co-founder Professor David Flynn explains: "At present, when gritters spread salt over multiple days, no account is taken as to how much de-icer salt is left on the road.

"We have created an affordable and robust means of assessing the road surface conditions and accurately determine how much salt, if any, a stretch of road...
