This study examines the impact of emerging transport trends on the Western Balkans and their potential to improve the sustainability and efficiency of the transport sector in the region. In the context of global efforts to reduce environmental impacts and improve transport safety, the study aims to better understand the perspective of the business...

Most of the air pollution originates from combustion processes, whereby traffic is one of the most important sources. Road traffic is one of the leading factors of pollution, so determining its contribution to pollution and overall emissions is very important. This study is a tool to develop a calculus method to determine the specific and annual em...

The elevation of airport runways is specified in the operations manuals and in globally accepted design guidelines. Airport runways are constantly exposed to various physical and weather factors. However, these factors can deteriorate the condition of the runway to the point where it becomes unusable. Monitoring and the continuous inspection of run...

Airport runways are exposed to large traffic loads and other external factors which cause their transformation. Monitoring the state of the unevenness and determining the runway defectiveness is a complex procedure which includes fast and qualitative measurements of the execution of flatness, their evaluation and the determination of the level of r...

Runways are exposed to significant burdens and other external factors that cause their deformation. Monitoring runway deformities and determining the resulting damage is a complicated procedure which requires a rapid and accurate assessment of these deformities and evaluation of the damage they cause. In this study, an optimized process to determin...

On-line response dynamic traffic management system (DTMS) seems to be the key solution for resolving many and the most important traffic problems in urban areas. Commonly used on-line response DTMS consists of on-road equipment (detectors, variable message signs etc.) and computer aided system. Such a system is generally installed in world metropol...

The main purpose of this study was to investigate the use of various chaotic pattern recognition methods for traffic flow prediction. Traffic flow is a variable, dynamic and complex system, which is non-linear and unpredictable. The emergence of traffic flow congestion in road traffic is estimated when the traffic load on a specific section of the...

Povzetek Vozniki so v času razvoja tehnologije obremenjeni predvsem z moderno tehnologijo, ki nam jo ponuja sedanjost. Motnje voznika med vožnjo lahko razdelimo na štiri temeljne skupine: vizualne motnje; voznik ne gleda smeri vožnje, slušne motnje; voznika moti zvok, zaradi katerega ni pozo-ren na trenutno prometno situacijo, motnje rok; voznik ne...

This paper examines the advantages and disadvantages of cable cars in public transport within urban areas. The advantages of cable car transport compared to other modes of transport are its quiet operation with an environmentally-acceptable electric drive and the possibility of transporting passengers above the ground, which can provide additional...

The article focuses on the identification of those relevant technical-technological criteria of charging fees for the use of railway infrastructure, which most affect the efficiency and economic viability of a particular model for charging. Railway charging system can be economically sustainable only if the charges (user fees) cover the desired per...

Povzetek Prispevek obravnava določitev tistih merodajnih tehnično–tehnoloških kriterijev za zara-čunavanje uporabnine za uporabo železniške infrastrukture, ki najbolj vplivajo na učinkovitost in ekonomsko vzdržnost posameznega modela za zaračunavanje uporabnine. Sistem zaračunavanja uporabnine je namreč na dolgi rok lahko ekonomsko vzdržen, le če s...

This study focuses on the importance of the development of maritime container ports in the case involving transatlantic container transport in order to ascertain an optimal model of container flows between container terminals in the east- ern coast of the United States and those in Western and Northern Europe. The model proposed by the authors is d...

This article aims to determine the development (rate) of maritime container ports in a case involving transatlantic container transport in order to ascertain a model of container flows between container ter- minals in the United States and container terminals in Western and Northern Europe. The model proposed by the authors is made using the follow...

The paper is based on the question whether the existing (legislation determined) method for determining the visibility length on passive protected level railroad crossings insures the relevant level of traffic safety. It has been rec-ognised that using of such method does not provide stopping of road driver vehicles in front of railroad crossing in...

Present work deals with analyzing dynamic traffic model of traffic delays, capacity, speed and other indicators, which affect on road traffic characteristics and living conditions in urban areas. Traffic models will include medium-size road network (lane type, lane width, lane length and lane grade), centroids, traffic data for morning peak hour pe...

The cableway transport system is very important for the Slovenian tourist economy. Within the Slovene transport system, the cableway transport subsystem has a specific role because it allows and ensures access to regions which are difficult to access or completely inaccessible by other transport subsystems owing to the configuration of the area. Th...

Zbog lošeg stanja prometne sigurnosti na cestovno željezničkim prijelazima u razini (ne samo u Republici Sloveniji) koji su zaštićeni sa pasivnima sigurnosnima mjerama (odnosno samo prometnom signalizacijom) bitno je promptno provjeravati stanje polja preglednosti. U zavisnosti od toga potrebno je određivati opseg pasivnih sigurnosnih mjera na nači...

Modern approach to transportation system research Is based on the system theory. System analysis is relevant. Constant transportation technique and technology development caused by the need of conformation to the new market conditions is the basis for such an approach. The model approach for resolving the problems of public passenger transport is p...

The introduction of contemporary procedures to fleet management processes has recently changed the work planning and supervision of driver's work activities. Tendencies to control the implementation of driver's work have been present in modem professional practice for quite a long time; however, the equipment available on the market limited its imp...

This article offers a survey of the cun·ent decentralised form of railway traffic management within the public railway infra-stntcture in the The Republic of Slovenia, which is the result of out-of-date and worn-out safety installations of railway stations and railway lines. The article presents a new model of railway traffic management as the basi...

It is very complex to assure the dynamics of traffic network in urban environment because of the intensity of traffic flows and the limited space in the urban area. Signalized intersections are undoubtedly very important and frequent element in road traffic network in urban regions, which greatly influences the traffic flow dynamics on each section...

The transportation of hazardous goods represents an economic activity whose consequences can have serious impact on the safety of transportation, the environment and human health. With the aim of reviewing the elements that affect the activity, this article presents a model for the transportation of hazardous goods of which, generally, there are tw...

From its theoretical and practical point of view, traffic is one of the fundamental factors of the economy in a state. In the developed European countries, a rational production of transport se1vices is presented by multimodal transport and the correct selection of a logistic operator. The aim of multimodal transport is to link together different f...

Operation efficiency of mountain resorts systems depends largely on harmonious operation of the most important and therefore most influential elements of ropeway transportation and tourist subsystems. Within the framework of a tourist subsystem, the extent and quality of a tourist offer for long-staying quests play an essential par. Harmonized deve...

The ropeway transportation subsystem plays a major role in mountain resort systems. It is characterised by an exceptional inle1weavement of interactions of single system elements. In order to provide sustainable development of the entire mountain res on systems, the real capacity of the ropeway transp01tation system was set. Real capacity of the ro...
