One of the most important aspects affecting both the safety and reliability of transport systems is the issue of proper positioning of moving transport means in the context of tracking their location while moving within the transport network. Therefore, this article presents the issue of the importance of information for the operational reliability of a selected subsystem related to the detection of a rail vehicle before a railway-road crossing, which is a critical infrastructure element and a particularly dangerous element in the transport network. The article presents an original and own vibration method for predicting the movement of a transport means, using the example of early identification of approaching rail vehicles. Redundant information can be significant for the operational reliability of safety systems in transport. In this aspect, reliable and continuous, and above all, independent information flow is crucial, even at the cost of system redundancy.
