How we can help

real-time monitoring

Proactive weather checks

Road weather monitoring is the process of collecting and analyzing data related to weather conditions that can impact road safety and efficiency. This includes information on temperature, precipitation, visibility, wind speed and direction, and surface conditions such as ice or snow.

Don’t wait for bad weather conditions to cause traffic accidents and urgent maintenance tasks. Our sensors let you continuously monitor what matters, from downtown junctions to the open road.

Cameras can monitor the condition of road surfaces, detecting ice, snow, or other hazardous materials. This information is vital for determining when de-icing or snow removal operations are needed, ensuring safer driving conditions.

In-pavement sensors can also measure the temperature of the road surface and sub-surface. This information is crucial for determining the presence of freezing conditions, ice formation, or potential thawing, enabling timely deployment of de-icing measures as well as driver warnings.

reliable data

Long-lasting equipment

Rugged and durable weather stations and sensors are crucial for road weather applications due to the demanding conditions they often operate under. These devices need to withstand various environmental factors such as rain, snow, ice, wind, and temperature extremes while maintaining accuracy and reliability in data collection.

Everything we do is focused on providing you with reliable data and insights. That’s why every component in every AEM system is proven in some of the harshest roadside conditions on earth.

Insights you can trust

Track every risk

Roads are vulnerable to a range of weather conditions. We help you track temperature, potential floods, risk of snow and ice, and much more. Every data point builds to give you the insights you need to see risks long before they arrive.

Snow and ice reduce adhesion to the road surface, which can lead to loss of traction, skidding, and collisions. Falling temperatures after a period of snow or sleet can also result in icy conditions on roads, bridges, and overpasses, increasing the risk of accidents.

Heavy rains can lead to roadways flooding, creating dangerous driving conditions and necessitating detours. Additionally, rain can reduce visibility and make the road surface slippery, increasing the risk of accidents.

High temperatures can cause road surfaces to soften and expand, leading to buckling or warping. Conversely, very low temperatures can lead to contraction and cracking of road surfaces.

Strong crosswinds can pose a risk, particularly for high-sided vehicles and cyclists. They can also blow debris onto the road, creating hazards.

Furthermore, extreme weather events associated with climate variability can disrupt and damage roadway infrastructure.
