This research aims to examine the traffic noise levels and to improve the performances of the Calculation of Road Traffic Noise model (C.R.T.N.) by applying the statistical multiple linear regression approach. Research methods included traffic noise level measurements with a noise measuring device in an urban area, using a sampling method in different periods. An evaluation of the measured data and prediction results was performed. Based on the predicted values of the C.R.T.N. model and coefficient of determination (R2), multi-linear regression was carried out to determine statistically significant parameters. The obtained multi-linear regression equation defined a new form of C.R.T.N. model. When applying the new improved version based on the C.R.T.N. model, higher accuracy of prediction is achievable. It can be seen that by applying multi-linear regression, the obtained prediction values are acceptably equated with field measurements in the chosen research environment. So, in this way, the differences between the predicted values of the noise level and the values measured in the field were minimized. Finally it can be concluded that when applying the new improved version based on the C.R.T.N. model, higher accuracy of prediction is achievable.

Noise represents any unwanted sound that interferes with a person's work, psychological and health condition, and their rest time. Numerous studies indicate that noise affects changes in human behavior (aggression, social conflicts) and causes stress reactions associated with physiological reactions. It also affects the central and neurovegetative system, reduces attention and concentration ability, reduces work ability, and reduces work productivity. Noise pollution is a major environmental health problem in Europe, with the transport sector being its main cause. The noise level is mostly affected by the number of vehicles, traffic flow, relative share of passenger and freight vehicles, their speed, types and characteristics of the road, whether the traffic is one-way or two-way, intersections, weather conditions, etc. In order to adequately protect against the negative effects of traffic noise, it is necessary to take various measures to reduce it. This paper provides a comprehensive review of the literature with special measures for the protection, monitoring and reduction of the negative impact of traffic noise.

The subject of research in this paper is the planning of urban mobility development in the narrow part of Sarajevo using a model based on the growth matrix. The hypothesis of this research is: Based on the analysis of supply and demand of the city traffic system, good practices in sustainable urban mobility and existing strategies and development plans, a model for managing the whole planning process of sustainable urban mobility of the city traffic system in Sarajevo by 2026 can be proposed.In accordance with the experience of Europe’s main urban mobility observatory (Eltis) and sustainable urban mobility plans (SUMPs), the key elements are defined. The next step, after defining the elements of urban mobility, is to carry out the quantification of elements for 2016. Thereafter, there is a concise explanation of the growth matrix and model of managing the urban mobility planning process is created. In the research results, direct and indirect growth rates were elaborated and analyzed, i.e. the individual and synergic effects of the model. Finally, the synthesis of the research results was presented.

The aim of this paper is to propose the intermodal logistics Corridor Vc, relying on the European Union transport policy, which will be in the function of regional development. The main goal is to analyze a potential route of freight intermodal transport between the ports of Ploče and Brčko in order to popularize this intermodal line at the international level. Among the most important activities in achieving this goal is the integration in the Euro corridor system. This integration is of crucial importance for companies to successfully execute their supply chain processes both domestically and internationally. The paper is based on the analysis of the current socio-economic situation and the condition of the intermodal transport system in Bosnia and Herzegovina (BiH), as well as existing strategic studies and development plans. This paper sheds a light on the creation of a strong integrated intermodal freight transport network in BiH, that will be a quality alternative to other international intermodal flows from the aspect of shorter transport time, lower transport costs and more favorable ecological aspects of transportation.

This paper analyzes the supply and demand for services in public transportation of the city of Mostar. Based on a survey of public transportation, origin-destination (O-D) polls and surveys on the quality of public transport an attempt has been made to determine its current state and user satisfaction with the existing services thereby highlighting the shortcomings of public urban passenger transportation and the need for the introduction and design of urban (city) lines. The main goal of this research is the improvement and further development of the system of urban public passenger transportation, which should follow the development of the city and the establishment of a better relationship between transport demand and supply of urban public transport system in Mostar.
