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 :

SafetyNex risk on path

Now with a slower speed profile :

risk profile of SafetyNex 2

And finally the "good" safe speed profile :

risk profile of SafetyNex 3

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 smartphone : that makes SafetyNex compliant with all driver's privacu regulations and laws in Europe.

Applications :

. insurance and fleets : vocal alert when risk is too high. As you can see, it lets time to slow down and avoid potential accident. This leads to a reduction of accident rate and a reduction of personal injuries. Of course, risk values can be recorded to do stats (risk profiles) for UBI (Usage Based Insurance) applications. 

. Automotive : same application is navigation with risk alerts. But with a robotized braking system (ADAS), it is possible to trigger braking with risk value. In such a case, it is not emergency braking but rather anticipation braking. 
In addition, it is possible, in the case of HAD (highly Automated Driving) car, to control speed (longitudinal part of auto pilot) very easily : "if risk too high, then slow down", "if risk is low, then accelerate until risk becomes the max value you accept or until you're at the speed limit". You write your autopilot with very few lines of code !
