Road Surface Alerts

Mask Group 36-1

Using vehicle data to produce relevant and precise hazard warnings at the right locations.

Black ice on a shadowy patch. Aquaplaning behind a hairpin corner. Or a pothole no one ever saw. That’s when everything changes in a heartbeat – and you’ve only got a second, at best, to act.


The next level of vehicle safety

Road Surface Alerts (RSA) enhances vehicle safety by providing drivers with up-to-date driving condition alerts. This helps in reducing unexpected road hazards and emphasizes safety and awareness for drivers.

The product is a revolutionary service that empowers drivers with real-time road-related alerts. This stream of alerts, curated for drivers, can be seamlessly integrated into an existing service such as the built-in vehicle navigation system. Other options are vehicle apps powered by Android Automotive or other automotive platforms. With this cutting-edge technology, drivers can feel safer and more informed on the road, making every journey a confident and enjoyable experience.

Road Surface Alerts by NIRA

  • Dashboard Alerts – Get precise warnings as you approach hazardous areas, instead of general warnings based on temperature (such as the snowflake warning).

  • Navigation Alerts – Allowing your navigation system to include alerts, making trip planning easier and more precise and allowing a safer journey.

  • Third party application Alerts – The data is not tied to in-vehicle applications. Third party application providers can use data to produce safer applications for road or transport.

The most precise local hazard warnings


Based on worldleading friction estimation technology, Road Surface Alerts is the next generation local hazard warning system providing the most precise warnings ever.

From slippery road segments to aquaplaning – Road Surface Alerts increases driver awareness to eliminate the biggest hazard of all.

That’s the element of surprise.

  • Coverage where you need it
    Every day cars with our proprietary road measuring algorithm travels on average more than 22 million kilometers.

  • Data driven quality
    Quality and accuracy of alerts are not driven by single events (such as ABS braking), but from the complete view of the road surface built up by all contributing cars.
  • Precise warnings at relevant locations
    To influence driver behavior and increase the risk awareness, warnings need to be as precise as possible. Our map-matched alerts where it matters the most.

  • It starts with slipperiness warnings, but it doesn't end there
    Going forward, Road Surface Alerts will see more kinds of warnings, such as hydroplaning alerts, pot hole alerts, and more.

How does Road Surface Alerts work?

1. The tiniest change in friction - Using software only, we utilize existing sensors within the vehicle to measure the tiniest change in friction on the road. This could indicate that the surface is becoming slippery. The changes that can be detected are extremely small – much smaller than in measurement approaches used before.

2. Anonymized data from millions of vehicles - Data is generated from millions of cars and transmitted to the cloud. The data, which cannot be connected to any specific vehicle, is aggregated into the Road Surface Information cloud where it is map-matched and processed for further analysis.

3. Analysis and mapping - Data from different road segments is analyzed and hazardous situations in specific areas are pinpointed. The information is combined into the customer’s location platform, sending hazard alerts to vehicles and drivers.

4. A precise warning - As live, updated alerts are pushed to vehicles, drivers receive a warning when they approach a hazardous area – enabling them to become aware of potentially dangerous situations before they get there.
