Incidents involving trucks or semitrailers becoming lodged under overpasses or within tunnels due to insufficient clearance estimation remain a persistent challenge in transportation infrastructure. Such events often lead to significant traffic disruptions, costly structural damage, and potential safety hazards.

To mitigate these risks, advanced tunnel height detection systems are being implemented as a critical component of modern traffic management and vehicular safety solutions. A sensor detection and warning system has been developed and employed to warn vehicles exceeding height limits from entering. The system uses advanced sensors placed before tunnel entrances to detect the height of approaching vehicles. These sensors, typically infrared or laser-based, measure the vehicle's height as it approaches. If a truck exceeds the designated height limit, warning signs and signals are activated, alerting the driver to stop and redirect.

To deploy computer systems under the weather is always challenging. The equipment must endure extreme temperature fluctuations, from heat in summer to freezing conditions in winter. These changes can affect sensor accuracy and potentially cause component failure. In addition, constant exposure to rain and humidity can lead to electronics (sensors/ computers) malfunction or corrosion (circuit board). Also, environmental pollutants like dust and dirt can obstruct sensors, leading to inaccurate readings or complete failure. One of the other impacts is from the passing by vehicles. The constant vibration from passing vehicles can put stress on sensors and computers, potentially loosening connections or damaging internal components. Last but not least, being positioned out in the open, power source availability will be scarce.
