- The DAS/DTS solution combines artificial intelligence and fibre optics to increase road safety and is implemented in Portugal, on the A28 motorway, as part of the European project Transforming Transport, led by Indra and elected the best European Big Data project in 2019
- This technology was recently a finalist in the UK Highways Awards 2021, in the Industry Product of the Year category.
The DAS/DTS solution developed by Indra together with its technological partner Aragón Photonics Labs combines artificial intelligence and fibre optics to increase road safety, and monitors with a single device between 40 and 80 kilometres of road in real-time, allowing to detection any road incident up to 80 kilometres away and speed up the response to it. This technology was recently a finalist in the UK Highways Awards 2021, in the Industry Product of the Year category.
The Industry Product of the Year category of these awards recognizes organizations whose products or services bring to the market a paradigm shift or technology approach that has had an impact on the road industry due to its sustainability, efficiency or cost reduction, among other benefits.
One of the conditions to be eligible for the UK Highways Awards was that the product had been developed and made available for use in the road industry within the last three years. In the case of Indra’s DAS solution, it had already been implemented in Portugal on the A28 motorway (Norte Litoral), as part of the Transforming Transport project, led by Indra and elected the best European Big Data project in 2019.
“The nomination of the DAS/DTS solution in the UK Highways awards is a source of pride for us and a way of recognizing our work in this sector, and which encourages us to continue working and innovating so that the “mobility of the future” is increasingly closest“, says Hélder Alves, Indra’s Transport Director in Portugal.
DAS (Distributed Acoustic Sensing) technology is capable of detecting incidents through the vibration of optical fibre already installed in the infrastructure, while DTS (Distributed Thermal Sensing) technology uses the same optical fibre, but to detect temperature changes in critical highway infrastructures. , such as tunnels, for example.
By equipping both systems with artificial intelligence, using different algorithms and patterns, this technology is able to identify a wide range of circumstances, with a high degree of precision and at the moment they occur, such as accidents, reckless driving, speed changes. , traffic jams, falling rocks, falling objects, fires, intrusion into the fences (people or animals) or unauthorized stops.
The result is an accurate measurement that allows motorway operators to respond better and faster to drivers, with a sustainable solution that contributes to road safety, and can detect the presence of animals on the road and analyze the deterioration of the road using systems. more environmentally friendly. Furthermore, its easy adaptation to the environment, thanks to the use of existing infrastructure, reduces the impact of the additional implementation of other Intelligent Transport Systems on the roads.
The DTS solution is applicable to other types of transport infrastructure and is also in operation at Metro de Madrid, where a pilot project is being carried out to generate a thermal map of the entire network, in order to study the possible use of this energy. , as well as to facilitate the detection of fires or overheating in risk areas.
Devices that “listen”, “measure temperature” and report in real-time
DAS technology, based on Rayleigh’s visible or electromagnetic light scattering, is capable of converting tens of kilometres of optical fibre into thousands of vibration sensors. In other words, it makes it possible to “hear” the activity that takes place near the sensor cable and locate it with an accuracy of a few meters. Once the acoustic patterns are analyzed, using artificial intelligence, the DAS “understands” and classifies the events, generating different types of alarms.
In turn, DTS transforms tens of kilometres of fibre optics into thousands of thermometers, measuring the temperature near the sensor cable with incredible accuracy. By analyzing thermal patterns, it can generate alarms for anomalous thresholds or gradients, allowing, for example, motorway operators to respond quickly to fire alarms or alert drivers to icy pavements when fibre optic cable is laid close to the surface of the road. pavement.
