“…Making decisions on shaping the transport system requires information support [18][19][20]. Correct utilization of collected road safety information [21] can support the design and subsequent operation of the transport system, ensuring a high level of its reliability [22][23][24][25].…”

Increased demand for transport services and increased mobility of citizens can lead to a reduction in the level of reliability of transport systems. This in turn increases the demand for ways to assess the reliability of road infrastructure by both transport companies and individual users. The article presents the substantive basis of an application used to determine the reliability of transport infrastructure. Our approach was based on grouping information into clusters – based on the author's proprietary clustering method. Its basis is the detailed analysis of the road infrastructure in terms of errors occurring on it, divided into conceptual, design and operational errors. The methodology consists of three stages of clustering (1) creating a database of sections with assigned errors, (2) determining the initial clusters, (3) creating a final database of clusters, and then assessing the reliability of the road infrastructure of the transport system on their basis. The assumption is that the application will remain open-ended – i.e. the database will be developed by users. The proposed methodology was verified on the example of the selected route in Poland (between Kalisz and Szczecin). Based on the results obtained during the experiment on the selected route, errors in the road infrastructure were determined. This, in turn, allowed us to find that there are a number of errors in the road infrastructure, including errors with a high frequency of occurrence i.e. the so-called permanent errors, which further confirms the need to create an application to assess the reliability of the road infrastructure.

“…The key goal of the proper functioning of any transport system is to reach the highest level of reliability at any stage of the transport process [1][2][3]. The main features besides the reliability of these systems is that they must be available, sustainable, safe [4][5][6] and competitive [7,8].…”

The analysis of the reliability and availability of the data transmission system within the integral railway system is realized through the modeling of the system, i.e. its conditions and their connections. According to the defined measure of safety of the International union of railways (UIC) i.e. its committee ORE, defined by recommendations A 158 and A 124/RP, based on previous experience and the achieved level of technical development, we can estimate an acceptable value for the probabilities of certain conditions of the integral railway system and data transmission system. In the paper, the reliability and availability analysis was modeled using the Markov model for data transmission in the railway system with four conditions, for: correct system condition, presence of disturbances in the system, illegal (dangerous) system condition and system blocking condition. The validity for the application of process development modeling the reliability and availability of data transmission in the railway system will contribute to reducing the risk of inadmissible (dangerous) failures, improving maintenance planning and spare parts planning, moving from maintenance by time to maintenance by condition and reducing exploitation costs.
