Nexyad and HERE Technologies are now working together to apply cognitive artificial intelligence (AI) to road safety. The alliance combines the intelligence of Nexyad’s real-time data aggregation platform with the real-time accuracy of HERE maps.
The Nexyad aggregated data platform uses cognitive AI to combine extensive data sources in a vehicle in real time. It then interprets the data to assess whether a certain driving behaviour is appropriate given the surrounding context. Nexyad’s assessment, which can be delivered to a driver via a mobile phone, can be calculated from four sets of data only: HERE map, global navigation satellite system (GNSS), electronic horizon and acceleration. The platform is also scalable and can aggregate data from advanced driving assistant systems (ADAS) sensors to include camera, radar and lidar, weather (visibility and temperature), and traffic data.
Nexyad’s real-time data aggregation platform provides two output values 20 times every second: the lack of caution of the driver and the maximum speed recommended given the road conditions – legal speed limit, road roughness, topography of the road, weather, and traffic. Nexyad bases its analysis on several thousand road accident reports, using a set of rules from modern hybrid AI, which includes knowledge-based systems, deep learning, neural gas, PAC (possibly approximatively correct) learning, game theory, reinforcement learning, possibility theory and fuzzy logic.
By recommending a ‘maximum cautious speed’ based on real-time data that is context-specific to every single vehicle, driver and driving environment, Nexyad’s approach goes much further than the European requirement for vehicles to be aware of the legal speed limit on each road segment (Intelligent Speed Assist). Nexyad’s safety coach called SafetyNex acts as a true co-pilot for the driver as it provides real-time guidance, to anticipate possible emergency situations ahead that may lead to an accident. This proactive coaching activates while driving and has been demonstrated to reduce accident rates by at least 25%.
Risk score for drivers and autonomous shuttles
Nexyad provides drivers with a score that reflects the risk associated with their driving behavior. Nexyad’s platform is being used by insurers to provide recommendations to drivers and generate a risk profile. For example, Brightmile, a start-up incubated by Kamet, AXA’s insurer tech studio, is using Nexyad’s SafetyNex software as one of the parameters of their smartphone-based telematics solutions for fleets. India’s Montbleu also relies on Nexyad’s SafetyNex for its smartphone-based app ‘ROAD-Drive it Safe’. Milla, the French autonomous electric shuttle, uses SafetyNex to adopt vehicle speeds according to driving conditions and alerts the service operator (on-board and/or off-board) to take appropriate action when the level of risk is estimated as being too high.
Nexyad has started to integrate the HERE HD Live Map to provide OEMs with predictive automotive cruise control services whereby appropriate speeds are not only being recommended but automatically implemented. Moving forward, connected vehicles will use SafetyNex to assess the level of caution of their own driving and will be able to adopt the appropriate speed even in unknown road conditions.
“We found that the maps from HERE are accurate to the centimetre and constantly updated to the second,” says says Gérard Yahiaoui, CEO of Nexyad. “Every detail counts for us – the topography of the road, the exact positioning of the crossing, the location of a school. With our mission being to save lives, we cannot settle for anything less than the best.”
“Nexyad’s SafetyNex software is one of a kind – not only does it provide a score for the lack of caution of the driver, based on the environment in real time, it also recommends an appropriate driving speed,” adds Gilles Martinelli, director of automotive at HERE Technologies. “This is the future for predictive automotive cruise control systems, insurers and autonomous vehicles.”
