TomTom Hazard Warnings creates time-critical signals that alert drivers and vehicles to hazards as they happen. This gives more time to anticipate and adjust accordingly, increasing safety and comfort.

Features and benefits

With the fastest notifications, widest range of features and highest number of data sources on the market, TomTom Hazard Warnings rounds out our portfolio, providing drivers and automated vehicles with up-to-date traffic, road and weather warnings.

Fastest push alerts

Traditional systems work on a request-response model: an accident happens, it’s loaded onto the server and then waits for the vehicle to request new information on a particular stretch of road. This can take several minutes – at high speeds that delay can translate to long distances. We push alerts out, sending hazard warnings to the vehicle within seconds.
Industry’s fastest push alerts

Widest range of features offered

We offer nine different types of hazards such as Jam Tail Warnings, Broken Down Vehicle and Slippery Roads. This information enables a variety of use cases including enabling early visual and audio warnings of safety-critical incidents, planning the safest route with current conditions in mind, and adjusting speed in poor conditions.

Increased safety for automated vehicles

TomTom Hazard Warnings are making safe automated driving (AD) a reality. In lower levels of autonomy, the vehicle receives an alert and can adjust its behavior, with the driver maintaining control. When hazards are detected, the driver can be prompted to either deactivate the AD function or the system can automatically change behavior.

TomTom Hazard Warnings uses OpenLR ™ location referencing to pinpoint a hazard’s exact position on any type of road and quickly transmit that location to the vehicle.
