Road Surface Alerts

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

This is RSA

The next level in vehicle safety is here. Based on world-leading 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.

Road Surface Alerts - This is how it’s done

01
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.
02
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.
03
Analysis and mapping
Data from different road segments is analyzed and hazardous situations in specific areas are pinpointed. The information is combined into the customers location platform, sending hazard alerts to vehicles and drivers.
04
A precise warning
A live updated Road Surface Alerts is pushed to vehicles and drivers receive a warning when they approach a hazardous area. This way they are aware of potentially dangerous situations before they get there.

RSA at a glance

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 data helps driver to be alert where it matters the most
It starts with slipperiness warnings, but it doesn't end there
Road Surface Alerts will see more kinds of warnings going forward, such as hydroplaning alerts, pot hole alerts etc

RSI put into use

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.
