Rail transport has unmistakable sustainable (environmental and economic) advantages in goods transportation on a massive scale. Goods loading constitutes an important segment of goods transportation by rail. Incorrect loading can be a serious threat to traffic safety as well as a generator of unforeseen expenses related to goods, railway infrastructure and vehicles. At the beginning, the paper identifies the presence of incorrect loading into freight railcars. The analysis of the available loading software has led to the conclusion that no software offers adequate support to the planning and monitoring of the loading of goods into a covered railcar using a forklift truck. For this reason, the main aim of the research is to formulate a mathematical model that includes real-world constraints, as well as the design and implementation of an original user-friendly load planning and monitoring software system. Experimental evaluations of the implemented software have been made based on single and multiple railcar pallet loading problems, considering the following three optimization criteria: maximization of wagon load weight, maximization of wagon volume utilization and maximization of weighted profit. By testing the optimization and visualization features of the software and analyzing the results, it has been concluded that it can offer full support to real load planning and monitoring problems.

The article presents an outline of the law governing railway transport in comparison with the regulations for road transport. The comparison shows that railway entrepreneurs are much more encumbered with legal obligations than road carriers, which in part is due to the specificity of this branch of transport. The essential constraints to the competitiveness of railway transport relate to the cost of access to railway infrastructure and its condition. The article also points out the faulty legislation, disadvantageous to both modes of transport, and attempts to determine the impact of legal solutions for the development of rail transport.

Objective: To conduct safety evaluation of urban land in the process of goods traffic by railway transport in regions with natural hazards on the basis of system approaches. Methods: During safety evaluation, modern urban areas were considered as a complex multilevel system, concentrated mainly in large water basins and characterized by the presence of the developed railway infrastructure. Results: A complex approach of determining natural and anthropogenic hazards interrelation within the limits of an urban land was introduced. By breaking the problem of natural and anthropogenic causes of contingency within the limits of an urban land, the processes and phenomena of interrelation were considered, which, in case of integrated accounting, provides an opportunity to improve the level of forecast of land resistance to hazard occurrence. Practical importance: The developed approach and calculation data make it possible on a reasonable basis, to select measures to increase resistance, to assess the necessity in efficiency improvement of hazardous processes and phenomena monitoring, as well as to restrict the use of transportation infrastructure elements.

The article discusses the problem of railway safety management and the criteria for evaluating the traffic risk described in various scientific publications. The research aims to assess the risk posed to railway infrastructure objects and to create a model for safety risk evaluation. The research on the traffic safety risk with respect to the infrastructure of the rail transport system was divided into three stages. The Plan–Do–Check–Act (PDCA) model can be used for investigating the problem of managing railway traffic safety risks in the Lithuanian railways. The main threats to railway infrastructure objects are defined, and the catalogue of technical parameters of level crossings of the Lithuanian railways is presented. The maximum allowable train speed, the intensity of railway and road traffic, as well as the size (width) and visibility of level crossings from the train driver’s cab are chosen as the main criteria for evaluating the vulnerability of a level crossing. The logistic regression method has been applied to rank and assess the safety of level crossings of the Lithuanian railways. The validity of the model developed in the present work for assessing traffic safety risks at level crossings of Lithuanian railways is about 86%. The suggested risk evaluation model is flexible and can be easily adapted for the evaluation and monitoring of safety risk of other elements pertaining to railway infrastructure. Finally, the basic conclusions and recommendations are provided.

The need to minimize losses and accidents is an important factor in sustainable technical development. One of the industries characterized by a high level of danger is rail transport. This problem changes its scale with the increase in the number of vehicles, its traffic intensity and speed. Another special diffi-culty is that significant infrastructural development, which involves the construction of a large number of complex and expensive facilities such as interchanges, overpasses and underpasses, is impossible in today's economic environment. Therefore, there are some promising solutions aimed at developing and implementing a new class of systems that provide a high level of safety and are able to correct negative accident statistics and solve the problem of not harming people's lives on rail transport. The article is devoted to the problem of traffic safety at railway crossings, railway crosswalks and in the work areas of service personnel. An information approach aimed at improving traffic safety and timely informing road users about emergencies and dangerous situations in their area approach is developed in the work. It is offered to solve the mentioned above tasks at the expense of the creation of digital information systems of a new class. The main differences between the created systems are the use of microprocessor systems, wireless communications and energy-saving technologies. The systems themselves must meet modern requirements for reliability, fault tolerance, and dependability. The article describes some basic options for the implementation of control and information systems for railway crossings «Blagovist», railway crosswalks «Blagovist-Р» and for a mobile system for service personnel working on the tracks «Blago-vist-SP». The systems have technologies for autonomous operation and wireless transmission of infor-mation.

Abstract Road inspection regularity and existing types made by road maintenance crew have not been good enough to be aware what is really happening on the roads. Road users' contribution in road traffic safety is very important to ensure fast reaction on different road hazards. It is important to ensure not only the most common ways to report road hazards on state roads by phone, by email and on social media, but also expand data sources options in modern and user-friendly way. Waze navigation application already had functionality to report road hazards – to warn other application users, but no one acted to solve these road hazards until someone reported them through existing communication channels supported by Latvian State roads or Latvian road maintainer. To ensure better road traffic safety and faster reaction time on road hazards solving, Latvian road maintainer gained access to Waze report feed, and, in corporation with Riga Technical university, made a system for analysing and processing Waze data. As the result - Latvian roads maintainer can improve road safety by faster reaction to road hazards reported by Waze users. Today, up to 70 % from total reports processed by Latvian road maintainer are generated by Waze.

Development of human society also implies modernization, respectively extension a road and railway transport structures. From this perspective, in order to achieve performance in the field of traffic safety, actions are also required to monitor the slopes, tailings dumps (active or greened) adjacent to transport routes where there are uncertainties regarding their stability. Ignoring stability and landslides can lead to loss of life, as well as significant material damage. Thus, the paper mainly addresses the issue of monitoring the slopes adjacent to road and rail transport routes where there are uncertainties regarding the control of landslides, as well as possibility of alerting before this occurs. From the multitude of possible solutions to be applied in the field, an equipment was developed and realized, which was experienced in real working conditions, and the results confirm validity of assumptions and certify the operation.

In the context of growing competition between rail transport and other transport types, there is a need to improve the transportation process. In modern conditions, railway transport is the main link in the logistics chain of moving goods from the shipper to the receiver. The efficiency of the railway transport complex can be improved by using logistics principles in the organization of local work on the network sections. In this study, we suggest ways to solve the problem of improving the quality of service for freight owners and the efficiency of organizing local work, which is relevant for railways. To make decisions aimed at improving the efficiency of the organization of local work, a procedure for determining the costs of organizing and promoting local trains was developed, taking into account the costs on maintaining the railway infrastructure. Not only the operational activity of the railways, but also the quality of transport customers service, compliance with the regulatory deadlines for cargo delivery, depends on the choice of the optimal option for organizing local car traffic into trains and their promotion along the section. The option is selected by comparing the costs for each of the possible options for organizing local car traffic into trains and moving them along the section.

AbstractRail transport is an important sub-sector of transport infrastructure. Disruption of its operation due to emergencies can result in a reduction in functional parameters of provided services with consequent impacts on society. Identification of critical elements of this system enables its timely and effective protection. On that ground, the article presents a draft model for assessing the criticality of railway infrastructure elements. This model uses a systems approach and multicriteria semi-quantitative analysis with weighted criteria for calculating the criticality of individual elements of the railway infrastructure. In the conclusion, it presents a practical application of the proposed model including the discussion of results.
