Despite the constantly increasing demand of passengers and goods transport in Europe, the share of railway traffic is decreasing. One major reason appears to be congestion, which in turn results in frequent delays and in a general unreliability of the system. This fact has triggered the study of efficient ways to manage railway traffic, both off-line and real-time, by means of optimization and ...

in this article, multiple-product pvrp with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. a mathematical formulation was provided for this problem. each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. to solve the problem, two meta-heuristic methods...

Purpose: Automation of control systems for life support and service processes at infrastructure facilities passenger complex, in the single informational space, through digital platforms. Methods: The work uses experimental-theoretical level methods: cause-and-effect relationships, algorithmization, flowcharts others. Results: Practical recommendations transition from manual (personalized) labo...

The paper describes an integrated calculation methodology which, by simulating railway traffic, allows analysis of the performance of 2x25 kV 50 Hz electric traction systems. This methodology performs a multiconductor electrical analysis of the traction circuit utilising ATP-EMTP software (Alternative Transient Program-Electromagnetic Transient Program) and therefore additionally allows calcula...

Railway signalling can be defined as all systems used to control railway traffic safely, essentially to prevent trains from colliding. Over the years knoledgment and technology able to satisfy this issue have been implemented. After a long period during which each European nation used its own system (with the conseguent absence of interoperabilty among them), ERTMS/ETCS is currently the most co...

Also considered as not safety critical, modern railway traffic control system remains the ultimate solution to solve potentially dangerous scenarios (Belmonte 2006). Also, study the impact of Automatic Train Supervision (ATS) systems on railway safety is mandatory. The way of simulations analysis was chosen to perform necessary human operator’s behaviours evaluation. Real ATS system is installe...

Abstract: An ambition to avoid deadlock states occurring in simulation models of railway station operation requires an application of methods from resource allocation systems. Because of complexity of the underlying system, Banker’s algorithm has been chosen. To test its applicability, a coloured Petri net model of a simple railway station operation was constructed and the algorithm implemented...

Mobile mapping of environment information from a moving platform plays an important role in the automatic acquisition of GIS (Geographic Information Systems). The extraction of railway infrastructure from video frames captured on a driving train requires a robust visual object detection system that provides both high localization accuracy and the capability to cope with uncertain information. T...
