Introduction and Objective:

Highway and expressway weather monitoring is essential for ensuring the safety of drivers and passengers. With the use of advanced weather sensors, real-time data can be collected and analyzed to alert authorities of any potential hazards.

Transitioning from traditional methods of weather monitoring, such as manual observations and radar, weather sensors provide a more accurate and efficient way to monitor the weather conditions along highways and expressways. These sensors are able to detect a variety of weather phenomena, including precipitation, temperature, wind speed and direction, and visibility.

One of the key benefits of using weather sensors for highway and expressway weather monitoring is the ability to detect inclement weather conditions at an early stage. This allows for the quick response and proactive measures to be taken, reducing the risk of accidents and delays. For example, if a sensor detects a sudden drop in temperature, which could indicate the formation of black ice, authorities can quickly deploy salt trucks to treat the affected area.

Another advantage of weather sensors is the ability to monitor weather conditions in real time. This allows for the constant monitoring of weather patterns and the ability to quickly respond to any changes. The data collected by the sensors can also be used to create detailed weather forecasts, helping authorities to plan for potential hazards and make informed decisions.

The sensors used for highway and expressway weather monitoring are also durable and can withstand harsh weather conditions. They are designed to be installed in a variety of locations, including on the side of the road, on overpasses, and on bridges. This allows for comprehensive coverage of the area, ensuring that no weather conditions go undetected.

In conclusion, weather sensors are a critical tool for highway and expressway weather monitoring. They provide accurate, real-time data, allowing for early detection and quick response to inclement weather conditions. With the use of weather sensors, authorities can ensure the safety of drivers and passengers and minimize the impact of weather-related accidents and delays.


AnemometerAnemometer measures wind direction and speed. With the help of wind measurement, we can measure and forecast weather and reduce weather-related risk.

Barometric pressure – It measures air pressure in the atmosphere. Barometric pressure changes constantly so it is very important to measure it regularly to make process smooth.

Solar radiation sensor (Pyranometer) – Measures solar radiation levels from the sun in watts per square meter (used to calculate ‘Evapotranspiration’, the rate at which water evaporates from the soil).

Hygrometer – Measures relative humidity using a percentage measure of water vapor in the air.

Temperature sensor– It measures atmospheric temperature. Which helps to predict a rise in temperature and reduce risk factors. Rain Gauge – Measures liquid precipitation using an open container. They usually empty automatically and measure the amount of rainfall over a given time interval.


Condition of the Road Surface: The status of the road defines the qualitative coverage of the road surface. The sensors need to be able to distinguish the status “dry” and “not dry” which includes moist and wet. Additionally the status

“Frozen” has to be detected as well. The status of the road is mainly used to detect the danger of sleekness. The model uses the status of the road, the road temperature, dewing temperature, and air temperature.

Water film Thickness: Water film thickness is defined as the moistening of the road with water or dilution (salt). It is based on a plain surface. Its range is from 0.01 to 3 mm. The value per minute has to be determined by six measurements within the last minute.

Road Temperature: The road temperature defines the temperature of the layer between the road surface and the air mass or the water film above the road. The range needs to be from -30 to +80 °C and the resolution needs to 0.1 °C.
