Among the different factors driving the requirement for tunnel automation solutions are the strict regulations implemented by governments worldwide for road and railroad safety. In addition, the rising number of road accidents is propelling the requirement for tunnel automation solutions. Road safety is one of the major concerns globally, which is why governments are investing in innovative technologies for enhancing it. Tunnel automation offers improved security, better lighting, surveillance, air conditioning, and many other functionalities that can help prevent accidents.

Another major factor responsible for the growth of the tunnel automation market is the advancements in technologies, such as the internet of things (IoT), data analytics, and cloud storage. These solutions make it easier for utilities and public infrastructure firms to manage the different electronic and electrical aspects of tunnel automation by over-controlling them manually. Through these technologies, data can be transferred or shared between communication systems and other devices, such as lighting systems, thermostats, and sensors. The information received can be utilized to enhance the efficiency of the various electrical and electronic systems integrated into tunnels. 

As a result, both road and rail tunnels are rapidly being integrated with automated systems. Of these, in the coming years, the electrical and electronic systems of a larger number of railway tunnels than highway and roadway tunnels will be automated. According to P&S Intelligence, it would be due to the modernization of railway networks across the world. Several railway tunnels are built under the seabed or through mountains, stretching for scores of kilometers, making lights and HVAC systems a necessity.

Ventilation is one of the most-significant components inside any tunnel, and its manual operation can be costly and time taking. Automated HVAC systems control their own operations as per the conditions inside. This reduces the requirement for humans to constantly change HVAC settings and also brings down the energy consumption, which leads to lower operational expenses for utility and infrastructure companies. In addition, governments are implementing strict rules about installing air conditioning and ventilation systems in tunnels, which are rapidly being integrated with automation technology.
