France-based Nexyad, an embedded, real-time platform for aggregating on-board data and HERE Technologies, a leading location data and technology platform are now working together to apply cognitive AI to road safety.
Nexyad uses cognitive AI to aggregate extensive data sources in a vehicle in real-time and interprets them to assess whether a certain driving behaviour is appropriate given the surrounding context. The assessment can easily be delivered to a driver through a mobile phone, can be calculated from four sets of data only: HERE map, Global Navigation Satellite System, electronic horizon and acceleration. Nexyad’s 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.
The 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 and context-specific to every single vehicle, driver and driving environment, the company 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 says its safety coach called SafetyNex acts as a true co-pilot for the driver as it provides real-time guidance so as 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%.
Nexyad provides drivers with a score that reflects the risk associated with their driving behaviour. Its platform is being used by insurers to provide recommendations to drivers and generate a risk profile. India’s Montbleu also relies on Nexyad’s SafetyNex for its smartphone-based app ‘Road-Drive it Safe’. 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.
Gerrard Yahiaoui, CEO, Nexyad said: “We found that the maps from HERE are accurate to the centimetre and constantly updated to the second. 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.”
Gilles Martinelli, director of Automotive, HERE Technologies said: “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. This is the future for Predictive Automotive Cruise Control systems, insurers and autonomous vehicles.”
