(Extract) « La technologie développée au sein du partenariat s’appuie sur l’expertise de Nexyad et sa connaissance des risques routiers. SafetyNex est un module logiciel d’agrégation de données qui détecte 20 fois par seconde tout mande de prudence (appelé aussi risque de conduite) dans le comportement de conduite et en fonction du contexte de circulation. Intégrée dans une IA temps réel embarquée, la solution rend le véhicule plus intelligent et lui apprend à anticiper certaines situations, comme par exemple en ralentissant de manière préventive. Pour rendre ce module encore plus performant, l’idée est donc d’y associer la technologie de communication Y-SMART de YoGoKo. Cela permet d’augmenter la perception de l’environnement du véhicule. YoGoKo associe les communications V2X réalisées entre véhicules et avec l’infrastructure routière aux calculs de risques de collisions liés au comportement routier proposés par Nexyad. Le projet OASIS est expérimenté sur les navettes autonomes produites par MillaGroup (un acteur dont j’ai déjà parlé sur ce blog). Depuis 2019, les navettes MILLAPOD circulent tous les jours sur route ouverte à la vitesse de 30km/h en mode autonome. |
MillaGroup, YoGoKo and Nexyad launch OASIS project with driver assistance solution for everyone.
French excellence for a decisive step towards road safety autonomous vehicles.
Meudon, February 2021 – MillaGroup, Nexyad and YoGoKo launch the project in partnership OASIS (cOoperative Assistance System In Safe road), which announces new technological advances around cooperative driving assistance systems for all. The OASIS project proposes to develop and integrate new enhanced driving assistance features, based on an innovative data fusion solution. The data comes from V2X communications, driving risk assessment, and predictive collision estimation.
Although the number of accidents decreases each year in France, more than a third of fatal accidents are linked to a collision. Today, cooperative ADAS solutions integrate data related to the human factor and driver inattention. The implementation of these driving aids (ADAS) takes into account the concept of risk. In driving, 75% of the risk is linked to inappropriate driver behavior, linked to road and urban infrastructure.
The technology developed within the partnership is based on Nexyad’s expertise and knowledge of road risks. Safetynex is a data aggregation software module that detects 20 times per second any lack of caution (also called risk of driving) in driving behavior in view of the road context. Integrated into a real-time on-board AI, the solution makes the vehicle smarter and teaches it to anticipate certain situations, such as by slowing down preventively. Combining the Y-CONNECT solution with Y-SMART communication technology from YoGoKo increases the perception of the vehicle’s environment. YoGoKo combines V2X communications between vehicles and with the road infrastructure with the collision risk calculations related to road behavior offered by Nexyad.
The OASIS project offers a global vision of road safety, deployed in marketed vehicles. This is experienced on the autonomous shuttles produced by MillaGroup. MillaGroup is a mobility provider offering on-demand and multimodal transport solutions (for people and goods) in rural and peri-urban areas. Since 2019, MILLA POD shuttles have been running on an open road every day at a speed of 30 km/h in autonomous mode.
This combination of expertise in the area of risk management with Nexyad, connectivity with YoGoKo and vehicles deployment by MillaGroup will allow, among other things, an autonomous vehicle to drive thru an intersection with low visibility and priorities.
Thus, the OASIS project brings new perspectives in response to the needs of improving road safety and increasing the perception of the vehicle’s environment. The system deployed, with risk traceability, takes into account the legal aspect and will make it possible to dispel the debate on liability in the event of an accident:
– an assessment of driver behavior based on risk
– improved predictive ACC and AD systems « aware » of the risk they are taking, and able to prove their level of caution at all times (in response to legal and insurance questions)
– a new collision warning
– a smarter predictive AEB
Whether it is for the detection of lack of caution, dangerous situations, or emergency situations, road safety is integrated. This decompart- mentalised approach is completely innovative compared to the segmented approach by « use case » of the automobile. A system vision that must bring rapid progress in road safety, and on a larger scale respond to societal challenges.

| how to make ACC automatically follow rules of the road (slightly slow down before an intersection, etc.) without long and complex development?
New developments are starting up everywhere to make ACCs smarter, which could, for example, automatically slow down slightly before an intersection, and then pick up the speed of initial cruise. The whole question is: when should the vehicle be made to slow down? crossing? turn ? school zone ? roundabout ? pedestrian zone ? pedestrian crossing? Traffic light ? stop sign ? give way ? etc. |
At every moment, SafetyNex detects any mismatch between driving behavior and driving context. Such a mismatch is interpreted as a lack of caution, and the degree of lack of caution is called « Driving risk »: this is the risk taken by the driver (human, human assisted by robots, or AD system). The higher the risk, the greater the number of emergency situations encountered by the vehicle. Conversely, the lower the risk, the lower the number of emergencies statistically encountered. Note : do not confuse the « driving risk » as defined above with criticality (probability of interpretation of trajectories, time to collision, etc.), the two concepts coexisting in road safety systems. For a given driving context, the driving risk depends ONLY on the speed profile of the vehicle approaching a potential singularity of infratructure. It then becomes clear that by regulating the speed we can keep the risk of driving below a maximum accepted value. SafetyNex is then used to define the setpoint speed value Vr (at each instant) which makes it possible to guarantee that we never exceed the maximum accepted. On the other hand, any current ACC already defines a speed setpoint Vo. By simply taking as the new speed setpoint the smaller of these two speeds, we obtain directly and without any further development, a vehicle that slows down before intersections (for example) with the « Good » speed profile which guarantees safe driving. This simple, validated, efficient, and quick to integrate system is currently being integrated by OEMs with support by NEXYAD. |

– SafetyNex: 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.
See 2 use cases below :
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…
Meanings of those words are very different and it is very important to distinguish them:
. HAZARD indicates presence of POTENTIAL DANGER: a water source is maybe pollute, you put a « HAZARD » sign on it. If after analysis you don’t find any bad molecule, you can drink the glass of water.
. CRITICALITY indicates a measurable level of DANGER. During a critical situation, CRITICALITY is measured by « time to collision », « probability of interception of trajectories », etc… in road safety.
. 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 » in order to stay in the safe zone.
Applications are: alert driver, or act automatically on the driving behavior of the vehicle (ACC, Autonomous Driving).
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.
BRIGHTMILE integrator of NEXYAD SafetyNex onboard software of Risk Assessment in real time, has unveil partnership with AXA. Congratulations to Dominic SAUNDERS and all Brightmile team.

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).
