The development of new technologies has significantly influenced railways modernization and has caused the appearance of high-speed rail which represent a safe, comfortable and ecologically sustainable way of transportation. The high-speed rail present a big step in a relation to conventional railways, where the biggest difference is speed which even entails a change of other organizational and operational parameters, better utilization of trains, higher performance of manpower and better service to users.  That is visible in many cities around the world where high-speed trains are used by billions of users. In the EU there is no unique high-speed railway network, besides that in many EU member countries various operational models are applied. The future of the high-speed railways market depends on political, economical and technical factors and challenges as high infrastructure costs, various rates of return on investment and the negative effects of economic crises. The main objective of the paper is to analyze infrastucture costs of high-speed rail in Europe and benefits such us  time savings, higher reliability, comfort, safety, reducing pollution and the release of capacity in the conventional rail network, roads and airport infrastructure.

In recent years, the European Union is a committed to sustainable development and has successfully integrated the sustainability dimension into many policy areas. The White Paper on Transport (2011) emphasises key objectives to ensure a sustainable European Union's transport system by 2050. In order to achieve these objectives, 30% of road freight transport should be shifted to railway and water transport as environmentally friendly modes of transport, at distances greater than 300km by 2030, and even more than 50% by 2050. Modal shift as a new paradigm of EU transport policy should be realized by the construction of efficient green freight corridors, requiring an adequate infrastructure and an efficient information and management system within the European multimodal transport network. Extension of the indicative TEN-T (Trans-European Transport Network) to Bosnia and Herzegovina offers an opportunity to become an integral part of the European multimodal transport network and to provide sustainable and effective transport rising the modal shift from roads to railways. In this paper, the modal shift on the TEN-T Corridor in Bosnia and Herzegovina will be modeled using a multi-criteria analysis focusing on the Analytical Hierarchy Process (AHP) software Expert Choice, to determine the weights of a range of criteria identified as influencing modal shift. The results obtained by this model will be discussed and an analysis of potential positive effects of modal shift in the economic, social and environmental aspects of sustainable transport will be given.

In the present-day environment pertaining to digitalisation, increasing competition on the market and changes in industries, the CRM as a system is an essential tool for success. The issue of CRM system application in higher education institutions is insufficiently researched, especially in the parts that should indicate a clear connection between participants in higher education and CRM in higher education institutions, and factors that decision makers should pay attention to when making decisions about CRM implementation. Therefore, the aim of the paper is to research the functionality, application and advantages of CRM in the higher education sector, and to determine the features that will facilitate effective decision-making on the implementation of CRM. As a result of the research, a proposal for a conceptual model/framework of CRM was presented. The proposal is presented for the purpose of making appropriate decisions for higher education institutions when it comes to developing their own or purchasing a ready-made CRM solution. From the scientific aspect, the paper contributes to the existing literature by providing decision makers with an insight into the structure of the CRM system, its elements, connections and functionalities, as well as a description of the model with the information they need to pay attention to when making decisions.
