The SNS system utilizes smart IoT road sensors that provide accurate information about the road and its surroundings. These sensors are strategically placed on the road, offering real-time data invaluable for managing road slipperiness. One of the key features of the IoT road sensor is its ability to measure the temperature of both the road surface and the underlying soil. Using an additional cylinder at the sensor's bottom, the system can measure both surface and deeper soil temperatures. This information is crucial for assessing the likelihood of freezing and planning gritting actions.

Another essential aspect of the SNS is the conductivity sensor, which detects the presence of salt on the road. The system can precisely measure whether there is enough salt on the road to prevent ice formation. If there is insufficient salt, an automatic notification can be generated to activate gritting actions.

What makes the SNS even more efficient is the integrated transmission unit. This unit sends data to a central computer every five minutes, ensuring real-time monitoring. Moreover, the station's battery boasts an impressive lifespan of up to seven years, making the system reliable and durable. One of the most remarkable advantages of the SNS is its ability to create a denser network of road sensors at an affordable price. This allows road managers to combat slipperiness more precisely and efficiently. The system offers the ability to coordinate gritting actions automatically and integrate traffic data, resulting in a significant improvement in traffic safety.

While traditional slipperiness notification systems have been in use for some time, the new IoT road sensor offers numerous advantages over older systems. With advanced features such as temperature and conductivity measurements, real-time monitoring, and a durable battery, the SNS is an essential tool for managing road slipperiness.

In summary, the Slipperiness Notification System (SNS) represents a leap forward in the battle against slipperiness and contributes to improved traffic safety and efficiency on roads, especially during winter months. This innovative system demonstrates how technology can be deployed to address the challenges posed by nature and enhance mobility and safety on the road.
