Today the warning arrives when the hazard is already there
The event: crash, obstacle, slippery road
Someone calls emergency services or reports it by hand in an app
The warning appears in navigation apps
Variable message signs, often after the event is over
Three limits to overturn
Seconds, not minutes: the data is born on the vehicle involved, without waiting for someone to report it.
Not just queues: grip, visibility, obstacles, stopped vehicles, crashes.
The warning reaches only those travelling that stretch, in that direction, in the following minutes.
Who warns approaching drivers today · and the gap that remains
Emergency calls and manual reports in apps. The warning arrives minutes later.
Only on new cars of one brand, only from emergency vehicles, or they only alert emergency services or the fleet manager.
From the vehicle, automatically, on any brand, including vehicles already on the road. It warns approaching drivers within seconds, by radio and over the network.
Every moving vehicle is already a sensor
Rain sensor, outside temperature, headlights and wipers
ABS, ESC and ASR interventions, wheel slip
Steering angle, brake, pedals: swerves and emergency braking
GNSS, accelerometers, TPMS, airbags, seat belts, engine
One on-board unit, two ways to install it
factory-fitted by the manufacturer
retrofit on the OBD-II port, with the same functions
A1 motorway, km 234: a car is stopped in the middle of the carriageway
Vehicle A gets a puncture, loses control, hits the guardrail and stops in the carriageway.
Puncture, loss of control, guardrail impact
On-board data fusion: tyres, deceleration, ESP, airbags, occupants, engine running
Signed V2X message, only to vehicles approaching in that direction
Alert with full data to the road operator, 112, traffic police, rescue and recovery
Passing vehicles confirm the event; traffic updates in navigation apps
Two phases, two channels, two alert levels
European DENM format over 5.9 GHz radio, signed. No mobile coverage needed.
Relevance zone: the event’s carriageway and direction. At 130 km/h, 5 minutes ≈ 11 km.
The message hops from vehicle to vehicle until the first one with 4G/5G coverage.
Lighting up the dashboard warning lights: the knot to untie
The device reads from the vehicle network and warns through its own interface: display, lights, audible signal, Android Auto or CarPlay.
UNECE R155 and R156: mandatory on all new EU vehicles since July 2024.
CJEU C-296/22: read while driving; write only when stationary.
Delegated Reg. (EU) 2026/699 on the OBD port.
The rules the project has to work with
But it must be respected: the ITS Directive asks precisely for safety information services on the core network.
A road pilot, three simple questions
From the event to the first vehicle warned.
Who should have received it and who should not.
Hopping from vehicle to vehicle until the first one with coverage.
Pilot hypothesis: a fleet of buses or heavy vehicles on one corridor, measured and validated by a university, joining the European Data for Road Safety ecosystem.
ABS, ESC, steering, pedals, TPMS and seats travel as each manufacturer’s own CAN messages: their specifications are needed.
From the OBD port, while driving, you can only read. Dashboard integration goes through factory fit, with the manufacturer.
Location data is hardly ever «fully anonymous» under the GDPR: we work with pseudonyms, minimal data and rotating certificates.
The ambition: from fleets to manufacturers
Standard on every new vehicle, worldwide, available to everyone.
From the device to the platform
simulates roadworks, abnormal loads and escorts before carrying them out
real-time events to road operators and National Access Points
Smart Place and Nexus Health use the same data
From prototype to manufacturers
OBD reading, IMU, V2X radio and own interface
Buses or heavy vehicles on one corridor, measured and validated by a university
Dashboard integration, R155, local alerts in the Euro NCAP 2026 protocol
More fleets, law enforcement, road operators
