ADAS FOR ROAD SAFETY USING MAP

Sometimes, accurate detection both by human perception and by sensors are not enough for road safety.
Nexyad has worked on some use cases for which classical ADAS can’t help.
So we have developed SafetyNex that reads and analyses the digital map (HERE, TOMTOM, OSM, etc.)
in front of the vehicle (4-5 seconds ahead) as a bird view to anticipate singularities of the road.
Then SafetyNex allows to vocally alert drivers when they approach these singularities
(curves, intersections, pedestrian crossing, etc…) in order, for them, to reduce speed and to lower risk of accident.   Of course, it is possible to equip vehicles with Adaptative Cruise Control (ACC) to reduce speed automatically before these singularities.

As a reminder, road safety studies show that if speed is reduced of 1mph to the right moment, risk of accident is lowered of 4% to 6%.
With SafetyNex alerts, drivers have time (at least 4 seconds) to reduce speed far more than 1mph.

GATHERING COMPUTER VISION DETECTION
WITH PREDICTION AND RISK ASSESSMENT:
THIS IS WHAT WE DO !

Because most automotive engineers have no knowledge in Road Safety, they usually do not know that 75% of driving-risk come from a driving behaviour that is inadequate to infrastructure characteristics (geometry of curve, narrowness, pattern of intersection – angles, number of input and output lanes, functionality of infrastructure – pedestrian crossing, school zone, … -, road signs – traffic light, stop sign, …). So they focus on vehicle performance in passive safety (deformation of vehicle during a crash, safety belt, air bag, etc… and active safety, vehicle detection and reflexe : emergency braking (AEB).

NEXYAD do not build cars, but as software company, we worked for 20 years with road safety experts and road infrastructure experts on 8 major scientific programs to acquire this specific knowledge. This is why our minimum viable product for road safety can run onboard on a smartphone or any other device, and reduces accident rate by 25% with only a map, accelerometers, and GNSS.
This year we can add NEXYAD computer vision modules that bring other risk factors; ObstaNex which brings interdistance and presence of vulrenables, RoadNex which brings size of drivable surface, and VisiNex which detects lacks of visibility.

This brings a complete onboard road safety platform: under deployment for telematics (fleets and insurers), ADAS, and Autonomous Vehicle. Available for cars, motorcycles, buses, trucks, trams, and soon for bicycles and other vulnerable mobility systems.

It is time to join modernity, and integrate our best technology into your valuable solutions, available everywhere…

 

 

HAZARD, CRITICALITY, and RISK in ROAD SAFETY ?

Meanings of those words are very different and it is very important to distinguish them:

. HAZARD indicates presence of POTENTIAL DANGER: if behind a door there are toxic materials, you write “HAZARD” on the door. But if the operator who opens the door has the appropriate helmet, he/she can do so at no RISK.

. CRITICALITY indicates a measurable level of DANGER. During a road accident, CRITICALITY is measured by “time to collision”, “probability of interception of trajectories”, etc.

. RISK indicates the absence of caution: if you put a glass near the edge of the table, you take a RISK. In this case HAZARD is the edge of the table. If the glass falls, at every moment you can measure CRITICALITY of the situation. If you have good reflexes, you can catch the glass. This is what AEB does for vehicles (ADAS).
If you want to avoid breaking the glass without using reflexes, you put the glass away from the edge. In road safety, it’s the same, and NEXYAD has developed a real-time embedded software tool that measures “how far we are from the edge”.

Applications are: alert driver, or act automatically on the driving behavior of the vehicle (ACC, Autonomous Driving).

OTN and Nexyad join forces in a strategic partnership for active rail safety.

The companies OTN and Nexyad join forces in a strategic partnership for active rail safety.

Saint Germain en Laye, April 20, 2020 – The company OTN, which develops safety products in the rail sector among others, announces the signature of a partnership with the company Nexyad, specializing in on-board risk assessment of accident, with the aim of developing solutions for predicting and preventing collision risks.

This partnership will significantly improve the performance of current detection systems, by offering a risk detection horizon adapted to the speed of traffic on trams, metros and trains.

This technological contribution will allow rapid migration from simple “detection” to “prediction”, thereby improving the overall safety of users and the environment close to the traffic lanes.

The combination of the skills and experience of our two companies will allow us to quickly develop a high-performance analysis system (images, signals, data) to identify the risks of railway equipment in traffic. After six months spent evaluating the work necessary for the development and adaptation of the algorithms, initially intended for road safety, we are happy that this partnership results in the development of prototypes which we will be able to test in real situation in the short term.

 

OTN, a company based in Saône et Loire, France, manufactures, designs and markets electrical and electromechanical equipment intended for various advanced markets, including railway.

Nexyad, a company based near Paris, markets a global road safety platform for telematics, Advanced Driver Assistance Systems, and Autonomous Vehicles, currently adapted to railway focus.

 

 

 

 

Nexyad quoted in The Union Journal

“Smart car sensors can predict danger”

“A start-up based in Dubai and also Detroit is amongst those examining innovative modern technology options that can bring those numbers down.

Derq is creating systems to much better comprehend where danger places are. The firm makes use of a mix of sensors on roadways, expert system, and also computer systems in vehicles to inform vehicle drivers of possible risks. […]

Derq is not the only firm operating in this area. Humanising Autonomy has actually created a “pedestrian intent prediction platform” planned to make independent automobiles much safer;” Driveri is a system that examines business automobile chauffeurs’ to boost their efficiency, and also Nexyad produces software application that can be constructed right into vehicles to sharp vehicle drivers of possible crashes.”

OLD TELEMATICS
Vs
NEW PROACTIVE TELEMATICS

Old telematics used to record driving behaviour data extracted from accelerometer: severe braking, cornering, etc.
At this old time, there were no other solution, but it was complex to use it :
. weak correlation between severe braking and accident were due to the fact that accident brings severe braking (and not the opposite)
. driver that doesn’t brake at all at STOP signs (700,000 accidents per year in the USA) were considered as “good drivers” (no severe braking).

Now there is a new technology, easy to integrate into telematics hardware (smartphone, telematics device, dashcam, etc.) that computes a real validated DRIVING-RISK, easy to use, and because it is computed in real time, it can trigger alerts for driver and then modify driving behaviour in due course, reducing accident rate by 20%. It is time to turn the page and contact us (we provide the technology, you can build a solution by integrating it into your system).
