This paper presents an integrated simulation, multivariate analysis and multiple decision analysis for railway system improvement and optimization. Furthermore, the integrated model is based on data envelopment analysis (DEA) and analytical hierarchy process (AHP) that is integrated with computer simulation [24]. The integrated DEA and AHP simulation model can be used for selecting optimum alte...

We propose machine learning models that capture the relation between passenger train arrival delays and various characteristics of a railway system. Such models can be used at the tactical level to evaluate effects of various changes in a railway system on train delays. We present the first application of support vector regression in the analysis of train delays and compare its performance with...

Abstract Railway operations are highly susceptible to delays and disruptions caused by various factors, such as technical issues, operational inefficiencies, unforeseen events. To counter these ensure efficient railway during real-time management, several rescheduling approaches can be implemented. Among approaches, passenger-oriented considers train while taking passenger data into account, op...

The objective of this paper is to present a framework developed for assisting railway operators into monitoring and controlling the quality of services provided to their passengers. This framework is based on the estimation of 22 indicators, grouped under six criteria, i.e. itinerary accuracy, system safety, cleanness, passenger comfort, servicing, and passenger information. The valuation of th...

This paper presents a hybrid scheduling technique for generating the predictive schedules of passenger trains. The algorithm, which represents a combination of simulated annealing and a constraint-based heuristic, has been designed using an object-oriented methodology and it is suitable for a primarily single-track railway with some double-track sections. The search process gets started from a ...

In Germany, competitive franchising is increasingly being used to procure passenger railway services that were previously provided by a state monopolist. This paper analyzes the 77 tenders that have taken place since the railway reform in 1994. The tenders differ with respect to the size of the franchise network, the required frequency of service, the duration of the contract and the proximity ...

Aims and Method Suicidal acts on underground railway networks are an area of public health concern. Our aim was to review recent epidemiological patterns of suicidal acts on the London Underground to inform future preventive interventions. Data from 2000 to 2010 were obtained from the British Transport Police via a Freedom of Information request. Results The mean annual rate of suicidal acts fr...
