[9] Traffic safety is a basic requirement for the operation of the railway system and is based on coordinated activities at the technical and administrative level. The administrative level includes the determination of the obligations and responsibilities of all stakeholders (Infrastructure Managers, Railway Undertakings, Suppliers, Railway Administration, Authorities), and is based on Railway Safety Directive 2004/49 / EC . The technical level includes the definition of standards for each component of the railway system. Continuous development of the safety system is a precondition for the future development of the Railway Infrastructure of Montenegro as a modern and reliable partner in the railway system. The safety system is expected to recognize risks in every work area, that may affect its efficiency in operation, and to eliminate or control them. Hence the need for constant monitoring of the functioning and improvement of the Safety Management System. This Paper presents a classification of the railway system, with all the specifics and infrastructural features. Then, the current state of the safety system in the Railway Infrastructure of Montenegro (RIoM) is analyzed. Finally, based on a comprehensive analysis, in order to improve the existing situation, the Paper presents the concept of Risk Management Models that can adversely affect the safety system.","PeriodicalId":295974,"journal":{"name":"JTTTP - JOURNAL OF TRAFFIC AND TRANSPORT THEORY AND PRACTICE","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116689720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper analyzes the influence of different types of roundabouts as one of the elements of the street system, on speed as one of the basic parameters of traffic flow that defines the functionality and quality of traffic conditions.

In order to achieve the best possible business results in the Railway Infrastructure of Montenegro, the theoretical and practical knowledge on which the management process is based, starting from planning (goal setting, determining ways to achieve goals, allocating required resources), organizing (a division of labor, delegation of authority, coordination), leadership (supervision, motivation, remuneration and punishment, training), conflict resolution) and lastely control (choice of control parameters, monitoring of results, comparison of planned and realized, taking corrective actions). In order to improve the current situation, the models of management of railway infrastructure are considered, for which as a manager builds and invests in railway infrastructure, takes care of its modernization, current maintenance, provides access and allocates infrastructure capacities and organizes and regulates railway traffic. In the processing of the management model, the work relies on the Strategy for the Development of Transport of Montenegro in the period 2019-2035, which establishes the situation in the areas of transport, defines the infrastructure, organizational and operational goals of the development of the transport system, which are realized through time and long-term implementation plans.","PeriodicalId":295974,"journal":{"name":"JTTTP - JOURNAL OF TRAFFIC AND TRANSPORT THEORY AND PRACTICE","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125409391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, special attention is drawn to advances in the development of autonomous driving systems, which will cause many changes in design, regulations and the environment. For the coming wave of change, we need to be adequately prepared and take part in global processes.

Vehicle overloading is considered to be one of the biggest causes of damage to part of the road surface, especially with regard to the load-bearing road substructure. The focus of the research is the vehicle overloading on the roads of Bosnia and Herzegovina, with special emphasis on determining the type and degree of overloaded vehicles and determining the equivalence factor (EF). In the research phase, data from weighing control stations were used, taking into account the total weight of vehicles, the distribution of total weight on vehicle axles and the equivalent standard axle load for a particular vehicle type over a period of two years. A high degree of overloading was found, especially 5-axle vehicles (58.7%). The level of overloading in the range of 10-20% in relation to the maximum allowed weight is especially apparent. The calculated EF is 3.64 and is higher than the standard EF.","PeriodicalId":295974,"journal":{"name":"JTTTP - JOURNAL OF TRAFFIC AND TRANSPORT THEORY AND PRACTICE","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127763691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main goal of this paper is to theoretically identify key impact in the case of transport companies when it comes to potential for improvements of environmental indicators. Improvements for the living environment can be caused by fleet renewal, tighter vehicle lifecycle management and via different government regulations. Key findings suggest that the fact whether a road transport company does business internationally.

The impact of a road transport system is so significant that its safety or lack of safety affects a wide range of social needs. Road safety or mobility without risk of death or injury affects health, poverty, equality, the environment, employment, education, gender equality and the sustainability of communities. Many nations around the world have improved the effect of pillar interventions by applying them selectively and strategically in accordance with the principles of the safe system approach. The safe system approach addresses problems closer to their root cause and on a broader level than conventional methods. The five pillars of road safety identified in the Global Plan for the Decade of Action 2011-2020 include a set of evidence-based interventions that can measurably improve road safety. Preparation and adoption of strategic documents - a traffic safety system development policy and strategy is a great way to demonstrate traffic safety management. The most important common denominator for all successful traffic safety practices is science-based strategic traffic safety management, which has clear, honest and publicly expressed political support. The paper presents the analysis of the third pillar „safer vehicles“ and its influence on the approach of the safe system from different aspects.","PeriodicalId":295974,"journal":{"name":"JTTTP - JOURNAL OF TRAFFIC AND TRANSPORT THEORY AND PRACTICE","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116921630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
