“…The solution to the above turned out to be the implementation of the European ETCS train control system, whose specificity of operation and system architecture show the possibility of using satellite navigation to locate rail vehicles. The analysis of ETCS integration with GNSS systems is the area of many studies aimed at confirming the fulfillment of safety and efficiency conditions in rail transport [9].…”

Detection of the current location of rail vehicles in the railway infrastructure network determines the safety, efficiency and reliability of rail transport. In addition, it indirectly affects the safety at rail-road crossings, i.e. also the BRD (Road Safety). In terms of efficiency and reliability of transport systems, the ability to detect a moving vehicle can improve the effective capacity of railway lines. As in the case of technical diagnostics, effective recognition of the current state of the transport network determines the efficiency of the transport system. The development of railways, with particular emphasis on high-speed railways, makes it necessary to modernize and improve railway traffic control devices and systems. A special area of development, ensuring the safe and effective use of rail transport, is the detection and location of rail vehicles moving on the railway infrastructure. The ability to determine the precise location of a rail vehicle is a key element in the reliable operation of rail transport. Therefore, in the field of devices and systems for the detection and location of rail vehicles, many studies and analyzes are carried out to develop existing or create new solutions dedicated to positioning rail vehicles.

The prospected advent of advanced train control systems, such as moving block and virtual coupling, raises the issue of the effects that uncertainty on critical parameters (such as position or speed) can have on dependability. Several approaches to the evaluation of such effects have been proposed, typically based on a state-based formal modelling of the system behaviour. We present a survey of such proposals.

“…The use of the GNNS in rail transport has been the subject of a number of research studies for many years, focusing on a variety of issues. These have included testing in laboratory conditions [7], establishing methodologies for risk analysis and evaluation of GNSS-based localization systems [8,9] and or detecting train integrity to quantify safety integrity level (SIL) criteria [10]. Additionally, the issues of signal reliability [11,12] and the adaptation of localization systems in case of signal failure [13][14][15] must be addressed when using the GNSS.…”

The identification of the position of rail vehicles plays a crucial role in the control of rail traffic. Available, up-to-date information on the position of vehicles allows us to efficiently deal with selected traffic situations where the position of vehicles is very important. The main objective of this article is to introduce (i) a concept of a solution for identification of the current position of rail vehicles based on the worldwide-recognized system of the GNSS with the use of an original railway network data model, and (ii) the use of this concept as supplementary support for the dispatcher control of rail traffic on regional lines. The solution was based on an original, multilayer rail network data model supporting (i) the identification of rail vehicle position and (ii) novel algorithms evaluating the mutual positions of several trains while detecting the selected crisis situation. In addition, original algorithms that enable automatic network model-building (on the database server level) directly from the official railway infrastructure database were developed. The verification of the proposed solutions (using rail traffic simulations) was focused on the evaluation of (i) the changing mutual positions (distances) of trains on the railway network, (ii) the detection of nonstandard or crisis traffic situations, and (iii) the results of the calculations of necessary braking distances of trains for stopping and collision avoidance. The above verification demonstrated the good applicability of the proposed solutions for the potential deployment within supplementary software support for real traffic control. The described concept of the supplementary support determined for railway traffic control (using the localization of trains by means of the GNSS) is intended mainly for regional, single-rail lines. This type of line is very often not sufficiently equipped with standard signaling and interlocking equipment to ensure the necessary traffic safety. Therefore, when deploying this support, the new algorithms for the automatic detection of critical traffic situations represent a significant potential contribution to increasing operational safety.
