DEFINITION OF PUBLIC SERVICE OBLIGATION POTENTIAL IN THE NEW EU MEMBER STATES

Martin HROMÁDKA

Summary. This paper deals with public service obligation, a form of state aid that applies to air services. The paper first provides general information on the European legislation applying to this form of state aid, and elaborates the legal framework and general principles. The second part is dedicated to a comparison of a similar subsidizing programme in the USA and Australia. An examination of current imposed public service obligation routes in Europe is provided in the following section. The(..)

PRODUCT ANALYSIS OF BUSINESS AVIATION COMPANIES: A TWO-DIMENSIONAL APPROACH

Ivana KIRSCHNEROVÁ

Summary. The traditional and current approach to business models in business aviation is based only on aircraft ownership and does not describe the business aviation segment of civil aviation sufficiently. In this paper, we apply a two-dimensional approach analysing the product of companies competing in the business aviation segment of civil aviation. Our analysis combines two product-related components: fleet attributes and portfolio of services to confirm a diversity of business aviation compa(..)

INFLUENCE OF IMPLEMENTATION OF TECHNOLOGICALLY ADVANCED EVACUATION MODELS ON THE PROCESS OF DECREASING THE RISK DURING ACCIDENTS IN AN LNG TERMINAL

Goran STANKOVIĆ/ Stojan PETELIN/ Peter VIDMAR/ Marko PERKOVIČ

Summary. The continuing growth of the LNG (liquid natural gas) industry has led to a rapid increase in the construction of LNG terminals and the need for accurate risk assessment models as accidents involving LNG are potentially hazardous and pose a major threat. One aspect of risk modeling - evacuation of people to the safe zones of an LNG terminal - is a complex problem that has yet to receive sufficient attention. The aim of this paper is to illustrate how the implementation of a technologica(..)

ANALYSIS OF POSSIBILITIES FOR THE USE OF VOLUME-DELAY FUNCTIONS IN THE PLANNING MODULE OF THE TRISTAR SYSTEM

Jacek OSKARBSKI/ Kazimierz JAMROZ/ Leszek SMOLAREK/ Marcin ZAWISZA/ Karol ŻARSKI

Summary. Travel time is a measure commonly used for traffic flow modelling and traffic control. It also helps to evaluate the quality of traffic control systems in urban areas. Traffic control systems that use traffic models to predict changes and disruptions in vehicle flows have to use vehicle speed-prediction models. Travel time estimation studies the effects of traffic volumes on a street section at an average speed. The TRISTAR Integrated Transport Management System, currently being deploye(..)

PASSIVE SAFETY OF HIGH-SPEED PASSENGER TRAINS AT ACCIDENT COLLISIONS ON 1520 MM GAUGE RAILWAYS

Maryna SOBOLEVSKA/ Igor TELYCHKO

Summary. The fundamental principles of the passive protection concept of high-speed passenger trains at accident collisions on 1520 mm gauge railways have been developed. The scientific methodology and mathematical models for the analysis of plastic deformation of cab frame elements and energy-absorbing devices (EAD) at an impact have been developed. The cab frame and EAD for a new-generation locomotive have been designed. The EAD prototype crash test has been carried out.

PROVIDING STABLE FRICTION PROPERTIES OF DISC BRAKES FOR RAILWAY VEHICLES

Yuri Y. OSENIN/ Douma Mansur AL-MAKHDI/ Oksana SERGIENKО/ Igor SOSNOV/ Aleksei CHESNOKOV

Summary. A new approach is developed to ensure the stability of the coefficient of friction at different braking modes for the entire speed range of braking high-speed ground transport. The new approach is a combination of friction materials with individual effort effects on the brake disc. A brake pad design and its performance are confirmed experimentally.

THREATS AND RISKS DURING TRANSPORTATION OF LNG ON EUROPEAN INLAND WATERWAYS

Andrea GALIERIKOVÁ/ Tomáš KALINA/ Jarmila SOSEDOVÁ

Summary. This paper describes guidelines and recommendations for emergencies and incidents on inland waterways. It also provides a review of existing knowledge of an LNG incident that occurred along the European inland waterway corridors. The article also reports on the latest progress in incident guidelines and describes the tools for port authorities to control credible scenarios produced by human or technical failures. This paper aims to analyse the risks that occur during transportation of l(..)

REDUCING ERRORS IN THE COMPANY’S WAREHOUSE PROCESS

Sebastjan ŠKERLIČ/ Robert MUHA

Summary. Warehousing is a labour-intensive process, requiring warehouse operators to use different methods of work and various equipment and to be in constant motion. During this process, various types of warehousing errors can occur, which can be reduced with the introduction of a suitable strategy. A prerequisite for this is to have sufficient knowledge of the specifics of error prevention in the warehouse process that are mainly linked to how warehouse operators perceive the usefulness of mod(..)

KASTOR – A VEHICLE AND CREW SCHEDULING SYSTEM FOR REGULAR BUS PASSENGER TRANSPORT

Stanislav PALÚCH/ Tomáš MAJER

Summary. The challenge in vehicle and crew scheduling is to arrange a given set of bus trips into running boards while minimizing certain objectives and complying with a given set of constraints. This scheduling was solved several tens years ago manually by a dispatcher who used his skill, experience, knowledge of history, and intuition. This attitude worked quite well in small instances but could not be applied in larger ones. Development of computers brought opportunities to build computerized(..)

CEMENT TRANSPORTATION LIMITED-FLEET MODELING AND ASSIGNING TO RATED DEMANDS

Narjes MASHHADI BANDANI/ Alireza NADERI/ Mohsen AKBARPOUR SHIRZAEI

Summary. Transportation is an inseparable part of the supply chain, with a key role in product distribution. This role is highlighted when ratio of “the cost of transportation” to “the value of goods” such as cement is significant. Iran has recently become one of the main centers of cement production in the world. However, transportation is the most important challenge in cement distribution because of weak structure of the transportation fleet and its independent action. Independence of and lac(..)

ANALYSIS OF THE CITY TRANSPORT SYSTEM’S DEVELOPMENT STRATEGY DESIGN PRINCIPLES WITH ACCOUNT OF RISKS AND SPECIFIC FEATURES OF SPATIAL DEVELOPMENT

Irina MAKAROVA/ Ksenia SHUBENKOVA/ Larisa GABSALIKHOVA

Summary. Transport system is the key indicator of sustainable spatial development, because if it is ineffective it can render the economy, the environment, and society vul-nerable. Despite the large number of already existing research, the city transportation sys-tem’s development strategy design is still a relevant objective, because the existing ways and strategies of the transport development may not always be applicable in certain cir-cumstances.
