In the last few years, electric buses (E-bus) have been increasingly used in many cities around the world (China, Europe, South America), making them the main alternative to conventional buses (diesel, CNG). The main advantages of using electric buses compared to conventional buses are higher energy efficiency, zero pollution emitted at the local level, more favorable carbon dioxide emissions observed at the regional or national level depending on the method of obtaining electricity, lower noise level. Since 2016, five electric buses have been operating in Belgrade on the EKO 1 line (Vukov spmenik-Belvil). The paper will present the environmental benefits of the use of electric buses observed through TTW (Tank to Wheel) and WTW (Well to Wheel) analysis, compared to diesel and CNG buses.","PeriodicalId":295974,"journal":{"name":"JTTTP - JOURNAL OF TRAFFIC AND TRANSPORT THEORY AND PRACTICE","volume":"71 1 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":"126108151","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}

Due to the characteristics of roundabouts and the way vehicles move, there is a reduction in speed, not only in the roundabout zone, but also at the approaches to the roundabout. 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. The research of speeds was done on the approaches to the roundabout, as one of the characteristic segments of the roundabout.","PeriodicalId":295974,"journal":{"name":"JTTTP - JOURNAL OF TRAFFIC AND TRANSPORT THEORY AND PRACTICE","volume":"9 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":"128464071","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}

In order to successfully manage organizations in the era of dramatic change, in this case ŽICG (Railway infrastructure of Montenegro), it is no longer sufficient to master the classical management process, but also to master the overall quality of management process. 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}

Although electric vehicles have become an absolute priority in some countries, their global expansion is happening and it is to be expected that they will become a near future in these regions as well. 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. In addition, it should be noted that the futuristic versions of vehicles capable of moving in multiple environments, on land, on or in water and in the air, are being widely promoted, and the EU is introducing mandatory application of some active and passive safety systems.","PeriodicalId":295974,"journal":{"name":"JTTTP - JOURNAL OF TRAFFIC AND TRANSPORT THEORY AND PRACTICE","volume":"43 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":"124945418","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}

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 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}

The basic assumption of this paper is that the level of fulfilment of environmental standards (measured by decreasing emissions of harmful gasses) is largely conditioned by the external influences, such as business strategy, performance or logistics management activities. 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.
