The use of the current methodology of the systematic approach, which differs from the existing ones by the integration of methods for modeling multidirectional processes in construction, as a complex system, tested on the example of a bridge crossing, increases the efficiency of the project and determines the direction of rationalizing organizational and technological solutions. Currently, the most promising companies focus on customer satisfaction within a clearly defined deadline. Failing to complete the planned work on time is an important problem in the transport facilities construction business since it entails additional expenses, which accordingly reduces the organization’s profit. Today, it is important to use alternative methods and approaches that allow for more efficient and quality project management that take into account the real construction stages’ cost and duration. The main study idea is to improve the process companies support to increase management efficiency indicators in the transport facilities construction. The research is based on a systematic approach and software applied to construction processes. Managerial ties combination with correctly selected and used resources, in the presence of innovative technologies, will allow achieving visible results in the implementation of projects. Project management based on a systematic approach, using modern software, is recommended for implementation and use in construction organizations, as this allows you to optimize scheduling and increase economic performance, even in times of uncertainty; allows you to reduce the cost of the resources and, to reduce the construction time; take into account the risks of the project, as well as control and track the actual implementation of projects for the construction of transport infrastructure facilities.

Abstract— There are various types of road barriers such as steel W beam, steel cable, concrete and wooden (timber) that have been used all over the World. They all have some advantages and disadvantages from different kinds of aspects such as construction time, ease of installation, low-cost, proven effectiveness, impact resistance, durability, service life, maintenance, etc. but to attain a more pleasant drive especially in historical and natural urban roads or scenic highways, installing wooden (timber) barriers can be considered as a more aesthetically pleasing alternative. In addition to aesthetic, wooden barriers can be preferred for their impact energy and sound absorption capabilities especially in urban roads. With the design, it is also estimated that light effect of oncoming traffic will be blocked. The main idea is to use hybrid barriers for both aesthetic safety feature in scenic or historical roads and urban furniture. This paper also summarizes comparisons among conventional road barrier systems considering the European standard EN 1317, Road Restraint Systems and provides a discussion of future designs.   Index Terms—road restraint system, timber barrier, hybrid barrier, road barrier, urban furniture

The Republic of Belarus has defined requirements for project management, which are recommended for all participants involved in project activities, and provide for the organization of a systematic approach to the development and implementation of projects involving architectural and construction activities for the construction, reconstruction and restoration of buildings and structures. Comprehensive pre-investment study of the project reduces the risk of starting an inefficient project, because in the process of developing the investment justification: the costs associated with construction and installation work are defined more accurately; engineering-geological and geodetic surveys of the territory under construction and technical conclusions based on the results of the survey of the technical condition of buildings, internal and external engineering systems of buildings are taken into account; all principal decisions are made on the supply of engineering and transport infrastructure; the project’s impact on the environment is assessed, and public discussions are held on the environmental impact assessment report with the state environmental expertise; determine the possibility and options for adjusting the parameters of the investment project, the adopted technology and architectural and planning solutions in order to improve the effectiveness of the project, if the data obtained indicate insufficient profitability of the project.This article describes the main provisions on the implementation of the pre-investment stage (development of pre-project documentation, business plan) of an investment project implemented in the metallurgical industry.

In this article, Professor Stabile examines the experimentation with Frederick Taylor's principles of scientific management by managers at the E. I. du Pont de Nemours Powder Company. Despite their initial interest in efficiency, those managers quickly recognized that there was a direct relationship between efficiency and safety, an issue Taylor had not considered. When it was alleged that the efficiency methods had been a factor in two explosions, the emphasis in the company shifted to a more systematic approach to promoting safety. As a consequence, the company was able to manage a full-scale expansion of its production during the First World War with little disruption resulting from safety problems.

The Competitiveness Of Enterprises

In order to attract more customers, transport enterprises strive towards providing transport services that fully meet their marketing criteria for quality. However, transport enterprises are not always capable of fully satisfying customers’ needs. Therefore, when choosing their “own” customers, transport enterprises need to develop a program for segmenting the transport market by recognizing its real capabilities for performing marketing events. The segmentation criteria depend on the economic and geographical peculiarities of the region, the development of transport infrastructure, the peculiarities of management and the transport enterprise’s capabilities.The report indicates the main stages of conducting effective segmentation of the cargo transport market. The necessity for analyzing the competitive advantages of enterprises working in a specific region has been determined; one instance involves the use of key factors that influence the quality of the transport service whose improvement in turn helps improve the competitiveness of enterprises. The paper’s main idea is to showcase the necessity and approaches for analyzing and assessing those target segments of the transport service market that carry out cargo freights. Segmentation is an essential element of the marketing concept that allows transport enterprises to choose those target segments of the market that are the most convenient and effective for them, thus guaranteeing the optimization of their expenses and profits.

Highway Network

The aim of this article is to analyze the pace of expansion of the network of highways and expressways over the past 15 years of membership in the European Union. Joining the European Union by such post-socialist countries as: Poland, Lithuania, Latvia, Estonia, the Czech Republic, Slovakia, Hungary, Slovenia (2004), Bulgaria, Romania (2007) and Croatia (2013) as well as the funds received for the development of transport infrastructure significantly contributed to the boom in the pace of road investments in these countries. The existing networks of highways and expressways in the 11 analyzed countries are at the stage of creating major national and international connections. The most advanced expansion of the national highway system is taking place in Poland and Hungary. Stable development, with a slight annual growth of the length of new highways, is taking place in Bulgaria, Croatia, the Czech Republic, Romania, Slovakia and Slovenia. Stagnation in the development of roads of this type is occurring in Lithuania, Latvia and Estonia. Toll roads are operated in 8 out of 11 analyzed countries. The vignette system for highways is used in Bulgaria, the Czech Republic, Slovakia, Slovenia, Romania and Hungary. Toll is paid at tollbooths in Croatia and Poland. Most of the highways in Central Europe are concentrated around the capital agglomerations, e.g. Budapest, Prague, Bratislava, Ljubljana, Zagreb, Sofia and Bucharest, with the exception of Warsaw, which is slowly rebuilding its central position in the network of expressways (A-2, S-7, S-8, S-17) in Poland. The first sections of highways in the discussed countries, except for Poland, were located around the capital cities. The layout of the highway network is often determined by the orography of the terrain, especially the course of mountain ranges, great rivers and coasts. Due to the varied topography, costs are rising, and the construction time of engineering structures such as tunnels, overpasses and bridges is longer, with countries such as Croatia, Slovenia, Slovakia, and recently also the Czech Republic, Poland and Romania being forced to build them.

Many factors influence the efficiency and quality of transport works. In particular, consultants and construction contractors of these works play important roles, and critical factors directly affect the quality of traffic works. If the quality of consultancy and construction is good, the project will reduce the total investment; if the contractor is good, the completion time of the new project is guaranteed, thus reducing construction costs. The longer the construction time is, the higher the cost of the project. In this study, the authors used optimal algorithms to evaluate past, present, and future contractors’ technical, technological, and performance effectiveness. Research results show that bidders are divided into three groups: highly effective bidders, stable contractors, and inefficient groups. Research results for this subject will help the government, regulatory agencies, and investors select good contractors as the basis for developing strategies and policies for the development of transport infrastructure.
