What is Winter Road Insights?

Winter conditions naturally pose a unique set of challenges. This is where Winter Road Insights (WRI) by NIRA comes in. WRI is a connected vehicle–based road condition monitoring system that continuously measures road surface conditions, accessibility, and safety during winter. Using anonymized and aggregated floating car data from more than two million vehicles, WRI identifies where roads are slippery, wet, cold, or exposed to changing friction conditions across entire road networks.

The system provides real-time insights and live network status updates that support effective winter maintenance planning, follow-up of performed measures, and validation of operational quality. WRI enables safer roads, optimized resource allocation, and cost-efficient winter operations for road authorities, operators, and contractors.

The four components for winter maintenance in Winter Road Insights:

Strategic Support

True performance evaluation of winter maintenance and road safety. With a large-scale data collection, it is possible to evaluate winter maintenance on a network level and make strategic improvements.

Situational Awareness

Enables regional overview and quick action at relevant locations. Immediate feedback on the results of winter maintenance and weather effects.

Slipperiness Alert

Quick slipperiness alerts directly to operators, independent of location. Every minute counts, alerts decreases the likelihood of an accident occurring.

Mobile RWIS

Real-time access to road weather properties. By fusing data from connected cars with road weather models, Mobile RWIS gives a continuous coverage not limited to the location of sensor stations.

Key capabilities of Winter Road Insights

Real-time friction monitoring.
High geographical and temporal coverage.
Scalable data from millions of vehicles.
Integration with existing road management systems.
Predictive and reactive decision support.
Automatic data collection with no additional measurement effort.

Who benefits from Winter Road Insights?

Winter Road Insights turns winter road data into actionable insight for decision-makers across the network:

Road authorities – Strengthen oversight of winter operations with objective, network-wide performance data.
Road operators and maintenance contractors – Improve responsiveness and accountability with reliable, time-critical decision support.
Municipalities – Support long-term winter strategy with measurable performance tracking and seasonal insights.
Infrastructure managers – Support long-term winter strategy with measurable performance tracking and seasonal insights.

Use cases: When Winter Road Insights makes the difference

✅ Live network monitoring
Get real-time visibility of slipperiness, wetness, and surface temperature across your entire road network to prioritize actions and allocate resources effectively.
✅ Targeted salting and snow removal
Identify exactly where friction is decreasing or conditions are deteriorating to avoid unnecessary treatments and reduce salt usage.
✅ Quality assurance and validation
Measure the outcome of performed winter maintenance actions and validate service levels using continuous, large-scale road condition data. Track KPIs, analyze historical trends, identify slippery-prone areas, and refine long-term winter road strategies with confidence.
