OBJECTIFICATION OF SUBJECTIVE ESTIMATION OF ABNORMAL CASES DANGER IN AIR TRAFFIC CONTROL

Olga ARINICHEVA/ Yakov DALINGER/ Aleksei MALISHEVSKII/ Nikolai SUKHIKH/ Yurii KHOROSHAVTSEV

In the article, the problems of objectification of the subjective danger estimation for abnormal cases in air traffic control are considered. An overview of currently existing approaches is given. In addition, the article presents the analysis of the statistical results of testing 252 air traffic controllers. This study reveals a subjective danger estimation inadequacy and its connection to air traffic controller’s potential extreme working capacity. A new approach to objectification of the subj(..)

COORDINATION OF LOCOMOTIVES TURNOVER AND SERVICING MODES

Petr KOZLOV/ Elena TIMUKHINA/ Nikolay TUSHIN

A coordinated calculation of two processes – locomotives turnover and servicing – is described. Locomotives turnover is calculated by optimization system Labyrinth and servicing by dynamic transportation problem. Service programs integrate these processes. A model of coordinated arrival of locomotives at servicing stations is proposed. The calculation consists of three interrelated steps. The first step is the calculation of the optimal locomotive turnover without considering servicing constrain(..)

FORECASTING THE OPERATIONAL ACTIVITIES OF THE SEA PASSENGER TERMINAL USING INTELLIGENT TECHNOLOGIES

Srećko KRILE/ Nikolai MAIOROV/ Vladimir FETISOV

Modern transport systems are characterized by the development and implementation of intelligent transport technologies. Today, dynamic forecast models are not used in practice in the operation of a passenger terminal. Decision making is based on some regulatory values for passenger traffic, but this is not sufficient for efficient terminal management. Modern passenger terminals are characterized by dynamic process variability and consideration of diverse options, taking into account the criteria(..)

AN APPLICATION OF AHP METHOD FOR EXAMINING THE TRANSPORT PLAN OF PASSENGER TRAINS IN BULGARIAN RAILWAY NETWORK

Svetla STOILOVA/ Radina NIKOLOVA

In this study, a methodology was developed for transport plan selection of intercity trains in railway network using the method of Analytic Hierarchy Process (AHP). For studying the transport plan, the following indicators have been chosen: the transport satisfaction, average number of train stops, average distance travelled, average speed, reliability, availability of service with direct transport and transport capacity. The methodology includes determination of variant schemes of transportatio(..)

ASSESSMENT OF RAILWAY LINES: AN EFFICIENCY RATING ANALYSIS FOR BALTIC COUNTRIES

Gediminas VAIČIŪNAS

The article investigates a possibility of using the traditional multi-criteria assessment methods to evaluate how significance of a railway line is distributed for the countries it crosses. The article analyses two examples of railway lines: the railway line Rail Baltica (Poland, Lithuania, Latvia and Estonia) and the container train Viking route (Lithuania, Belarus and Ukraine). When investigating for which countries the Rail Baltica project will have bigger significance, and for which smaller,(..)

THE METHODS OF REACTIVE POWER COMPENSATION IN THE 25 kV, 50 Hz CONTACT NETWORK

Lionginas LIUDVINAVIČIUS/ Lionginas LIUDVINAVIČIUS

The article analyses theoretical and practical solutions of reactive power compensation in the power grid of 25 kV, 50 Hz of the catenary. The article presents theoretical and practical studies (by providing circuits for connecting capacitor banks, structural circuits diagrams for the automatic control reactive power level, and calculating the parameters of capacitor banks) for the compensation of reactive power.

REINFORCEMENT OF COMPOSITE PIPELINES FOR MULTIPURPOSE TRANSPORTATION

Liudmyla TRYKOZ/ Svetlana KAMCHATNAYA/ Oksana PUSTOVOITOVA/ Armen ATYNIAN

The problem of monolithic behavior of a metal pipe and fiberglass safety cage has been considered in the article. The prestressed case does not only decrease the deformability of a pipe on-load but it also protects metal from corrosion. The ability to withstand the arising stresses has been investigated for both strip fiberglass reinforcement and the whole construction. It has been shown that the deformability of fiberglass depends on the kind of binder. The maximum strength value has been obtai(..)

TRAJECTORY-BASED MULTIMODAL TRANSPORT MANAGEMENT FOR RESILIENT TRANSPORTATION

Evelin ENGLER/ Stefan GEWIES/ Paweł BANYŚ/ Erik GRUNEWALD

The transport of goods and persons with two or more transport carriers (road, rail, air, inland waterway, or sea) results in multipartite transport chains whose profitability depends on the cost-effectiveness of the transport carriers involved as well as on the capability of multimodal transport management. Currently, differences with regard to the technical equipment used and infrastructural facilities available as well as administrative and public organizational structures in place are the maj(..)

IMPROVING SAFETY ON THE CROSSWALKS WITH THE USE OF FUZZY LOGIC

Irina MAKAROVA/ Ksenia SHUBENKOVA/ Vadim MAVRIN/ Polina BUYVOL

The article provides an analysis of the global trends in the field of city transport systems’ safety. Currently, the efforts to increase the proportion of trips made by foot or by non-motorized transport are being made. That is why the problem of ensuring safety of the most vulnerable road users is relevant. The statistics of traffic accidents with victims, as well as the factors that cause such accidents, is analysed. Simulation has shown that rational management can reduce the likelihood of ro(..)

OPTIMIZATION OF PERIODIC UNITARY ONLINE SCHEDULE OF TRANSPORT TASKS OF HIGHWAY ROAD TRAINS

Myroslav OLISKEVYCH

The paper is devoted to the problem of optimization of transport tasks’ execution schedule. The exploitation of a group of interdependent highway road trains is considered. The task differs from the known ones by limitations of the duration of a cycle within which a maximum number of goods transportation orders must be fulfilled. There are also limited intervals of time when loading and unloading of vehicles is permitted at appropriate points of a transport network. The solution of the problem c(..)

ANALYSIS AND VALIDATION OF THE DYNAMIC METHOD FOR DIAGNOSING DIESEL ENGINE CONNECTING ROD BEARINGS

Igor DANILOV/ Irina POPOVA/ Yury MOISEEV

The paper considers the problems related with diagnosing diesel engine crank gears, and presents most widely used methods for their diagnosis. The authors provide arguments in favour of dynamic health status identification of connecting-rod bearings in terms of the oil layer thickness. For the first time the dependence is obtained of the oil layer thickness in conrod bearings from the rotation frequency of the crankshaft and the pressure in the lubrication system.

THE IMPACT OF PRIMARY SUSPENSION STIFFNESS OF 2-AXLE BOGIE OF MKIII PASSENGER CAR ON ITS DYNAMICAL BEHAVIOUR

Krzysztof ZBOINSKI/ Milena GOLOFIT-STAWINSKA

This article presents results of the study on the impact of stiffness in vehicle primary suspension for lateral direction kzy and longitudinal direction kzx. The study was carried out for 2-axle bogie of MKIII passenger car. The problem was solved by numerical tests performed with the simulation software for dynamics of vehicle-track system. Performed study consisted in varying both stiffness types through change of their values from 0.001 to 1000 times as compared to nominal value.

IMPROVING METROLOGICAL PROPERTIES OF ELECTRIC TRACTION ENERGY METERS USING FUZZY CONTROLLERS

Bartosz DOMINIKOWSKI/ Krzysztof PACHOLSKI/ Jan ANUSZCZYK/ Andrzej GOCEK

This paper presents the possibility of using a fuzzy controller to correct metrological properties of an electric traction energy meter. So far, no algorithms based on fuzzy logic to determine the desired conversion value of the current channel of the electricity meter have been applied. Currently, for the mentioned channel, conventional methods of gain determination are used, based on a sequential algorithm that controls operation of the programmable gain amplifier. The proposed corrector is de(..)
