SafetyNex driving risk estimation during driving : anticipation of danger

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

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]

What is driving risk and why most apps DO NOT measure it although they seem to be interesting

What is driving risk and why most apps DO NOT measure it although they seem to be interesting Driving risk assessment is now of interest of : . telematics solutions providers . fleet managers (for prevention) . car insurers (for prevention, and UBI) A lot of applications then explain how they estimate driving risk. But, by the way, what is driving risk ? A lot of people seem to think that driving risk and accident are quite the same. If I observe accident, then I will learn and do stats and find a way to estimate driving risk.... [Lire la suite]
