COMPARISON OF HEALTH vs AUTOMOTIVE SECTORS FOR SAFETY   NEXYAD poposes a comparison between HEALTH and AUTOMOTIVE sectors approaches for safty improvement. In particular, we explain that criticality assessment is very different from risk assessment: one notion (criticality assessment) is linked to emergency situations, and that the other notion (risk assessment) is linked to normal situations and the question "how to behave in order to avoid emergency situations". Here is the presentation:   Read... [Lire la suite]

A Game Changer for Road Safety: the Global Road Safety Platform by NEXYAD NEXYAD recently launched a Global Road Safety Platform that can assess driving risk, onboard, in real time, 20 times per second. This technology is a game changer for road safety: currently under deployment for telematics matters (fleet risk management, and Usag Based Insurance), it has been shown and validated that alerting driver when risk starts to increase a little to much can reduce accident rate by 20%. See figure below:   NEXYAD proactive... [Lire la suite]

An Autonomous Vehicle that drives like a good human driver Autonomous véhicles are one of the main R&D subject in automotive sector. Autonomoy has been described in a functional way and classified in 6 levels, from 0 to 5. Today, intelligent cars that are for sale (TESLA, ...) are said to be level 3, and some car munifacturers claim that they have demo cars with a level 4. The chain of the Autonomous Driving System (AD System) is quite always a feed forward chain, from sensors to actuators, and applies or may apply Artificial... [Lire la suite]

Visibiity measurement, road and obstacle detection : what is the differentiation of NEXYAD algorithms NEXYAD is the leader of real time computind with their technology SafetyNex. SafetyNex is not an ADAS system, it is an anticipation one : without detecting anything, just know where you drive, can you know what cautiousness rules of driving you should follow. SafetyNex is a real time coach that computes in real time the driving risk that the driver is currently taking.. if driver in a human being, it has been shown that SafetyNex... [Lire la suite]

SELF-DRIVING CAR MUST DRIVE "WELL" IN REGULAR CONDITION … SOUNDS EASY ? READ THIS BEFORE AND THEN TELL Human drivers don't have the sharp reflexes of ADAS. But they have only 1 accident in average every 100 000 km and 3 fatalities in average every billion km (OECD). Drivers that have the best reflexes are in average the Young ones - 18 to 25 - (biology). However, they also have much more accident than the 50 years old drivers (not as fast as they used to be when they were 20). Well, it seems that finally road safety is not... [Lire la suite]

FOUR SHADES OF ROAD SAFETY : ANTICIPATION, ADAS, PASSIVE SAFETY Here is a diagram of different shades of road safety. The pyramid witdh corresponds to the number of cases. "Normal" driving is the regerence, is is the most frequent situation, while fatality is fortunately an exception. Tools among the pyramid are filters made to avoid fatality :. SafetyNex (by NEXYAD) is today the 1st and only tool made to stay in normal driving situation (not to be in emergency).. ADAS (Advanced Driver Assistance Systems) are made to avoid or...

The Car of the Future May Have...Legs Automobiles have played a huge part in American history, but the rise of the gasoline-powered horseless carriage was not preordained. Cars as we know them evolved in response to a specific set of circumstances. Given the proper impetus, they might easily—radically—evolve again. By the turn of the 20th century, inventors had built engines run by steam and electricity as well as gas. Each had crippling drawbacks. Steam-powered cars took a long time to fire up; electric cars were slow and... [Lire la suite]

Sometimes, accurate ADAS sensors are not enough in road safety, there are many cases where accurate ADAS sensors detection is not enough, because dangerous situations come from the notion of "surprise". This video shows some examples : NEXYAD developed a real time dynamical driving risk assessment SafetyNex that reads difficulties of the infrastructure on the digital map. This map is an a priori knowledge that should be used in addition to sensors. To know more : https://www.youtube.com/watch?v=bY2aDm8kfy8

SafetyNex driving risk estimation during driving : anticipation of danger SafetyNex estimates driving risk 20 times per second, during driving (real time). On the following figure, you can see risk rising when approaching a stop sign with an inappropriate car speed : Now with a slower speed profile : And finally the "good" safe speed profile : This estimation is computed INSIDE the local device (inside the car). Current implementation is on smartphones (IOS and Android), then computing of risk is completely done INSIDE the... [Lire la suite]

Use Case of computer vision ADAS system (RoadNex free space detection) : automatic predictive braking NEXYAD made some tries of using their module RoadNex for predictive braking. RoadNex is a computer vision based module for road detection : . detection of drivable area borders and detection of free space (drivable area surface) :   The idea is that RoadNex is NOT and obstacle detector, but ifever the drivable area is going thinner or smaller, thenthere is a chance that an obstacle should be detected. It means that RoadNex... [Lire la suite]
