Mapping specialist HERE claims to have jointly developed the next-generation cognitive artificial intelligence driven road safety aid.
Working with Nexyad, an embedded platform for aggregating on-board data, the platform claims to aggregate extensive data sources in a vehicle in real time and interprets them to assess whether a certain driving behavior is appropriate given the surrounding context. Its assessment, which can be delivered to a driver via a mobile phone, uses four sets of data only: HERE map, Global Navigation Satellite System, electronic horizon and acceleration. The platform is scalable and can aggregate data from ADAS sensors to include camera, radar and LiDAR, weather (visibility and temperature) and traffic data.
The platform provides two output values 20 times every second – any the lack of caution by the driver and the maximum speed recommended given the road conditions, including the 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, ‘possibly approximatively correct’ learning, game theory, reinforcement learning, possibility theory and fuzzy logic.
Nexyad’s safety coach, called SafetyNex, acts as a co-pilot offering advice and claims to reduce accident rates by at least 25%. The platform provides drivers with a score that reflects the risk associated with their driving behavior and can be used by insurers to assess risk.
Gilles Martinelli, director of automotive at 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.”
