Reliability, safety and efficiency – challenges for transport infrastructures

    Trans Motauto World, Vol. 5 (2020), Issue 3, pg(s) 93-97

    Transport infrastructure brings together conventional groundwork and innovative technologies in order to improve various aspects of transport system management and control. It enables anticipatory maintenance, planning and scheduling, resource management and aims to improve reliability and safety, increased capacity and asset utilization, better energy efficiency and lower emissions, higher customer service levels and increased economic feasibility. Transport infrastructures have long service life and great costs of building, manning, operating and maintaining throughout their life. Innovation and technology shifts proved to be important factors determining great changes in infrastructure potential and even determine its obsolescence. It is regarded as a concern throughout infrastructure’s entire life cycle and reflects changes in expectation regarding performances in functioning, safety and environmental effects.
    Performance and failure are illustrated conceptually and represented in a simplified form considering the evolution of technology, the influence of innovation breeding new generation rail infrastructure, all the way through infrastructure’s service life.
    According to the identified particularities, recommendations are to be made in order to insure a best practice in lifecycle management and transport infrastructure renewal in the context of improved reliability, safety and efficiency.

    Until Currently in the countries of Europe there is an intensification of the introduction of modern microprocessor systems of railway automation and the increase of their functional capabilities. The introduction of additional functions of control and monitoring systems, tightening of the requirements for the safety of their operation, mutual integration and unification of systems for various purposes, the complication of the implementation of processing of logical dependencies require fundamentally new approaches to the development of software and hardware of a new generation. In this regard, scientific and applied research aimed at the development of appropriate technologies is being conducted, based on the common methods and tools used in the formation of control and monitoring systems for various objects of the railway transport infrastructure. The proposed material contains the main results of such studies conducted over the past five years, as well as the main directions for further improving the development of microprocessor-based rail automation systems.
