Cooperative Intelligent Transportation Systems (C-ITS) aim to increase safety, optimise traffic flow, reduce traffic congestion, improve economic efficiency of transportation, and operate the telematic systems implemented in the infrastructure. The main goal is to increase the awareness of road users. These aforementioned indicators are crucial not only on conventional transport infrastructure but especially in tunnels, which require even stricter criteria and requirements for traffic safety and especially response to unexpected emergency situations (accident, traffic jam, fire, movement of people, etc.). The article focusses on the application of C-ITS in urban and highway tunnels, which could significantly contribute to the ease of orientation and guidance of road users, the elimination of unsafe drivers' behaviour, fluidity of traffic, and integrity of the control system in relation to vehicles and other technological systems that are widely used in tunnels. However, a major limitation in tunnels, and especially in complex urban tunnels with junctions, is the absence of a GNSS signal, which is the common source of positional data for a significant part of traffic applications for drivers. This makes tunnels a blind spot in the transport infrastructure, although the use of C-ITS in tunnels would be justified and would make even more sense than on other transport routes such as common highways. However, C-ITS itself can also be used for positioning through communication between the infrastructure and equipped vehicles. This article reports on the possibilities of using C-ITS communication for automatic positioning and thus making C-ITS applications operational in tunnels, which can provide new use cases that meet the specific needs and requirements of tunnel structures. Some data are important for the tunnel control system and the determination of even potential faults and the link to the service and maintenance, where equipment fault behaviour may occur, tracking of maintenance vehicles and the transmission of information through the tunnel control system, and many other data and information that can lead to a reduction in the economic intensity of the operation and maintenance of the tunnel, the reduction of damage caused by traffic excesses, as well as the increase of traffic flow and its efficient use. This paper will focus on specific C-ITS solutions applicable in practice in road tunnels, including safe and secure data transmission
