METHODS OF SUBSTANTIATION OF SPECIALIZATION OF RAILWAY LINES

Andrey BORODIN/ Evgenia PROKOFIEVA

The article proposes methodological principles for substantiating the specialization of main railway lines based on the primary types of passenger or freight traffic in order to improve the level of transport services, economic efficiency, and reliability of the transportation process. The search for a solution to the problem provides a rational distribution of transport flows and investment measures, with the subsequent finding of a compromised operation for a set of effective alternatives.

ANALYSIS OF HYDROSTATIC MECHANICAL TRANSMISSION EFFICIENCY IN THE PROCESS OF WHEELED VEHICLE BRAKING

Igor TARAN/ Iryna KLYMENKO

To analyze the braking process of a mine diesel locomotive with hydrostatic- mechanical transmission (HSMT), a mathematical model has been developed. In contrast to available models, this one takes into consideration rules of changes in controlling the parameters of hydrostatic drive (HSD) and implementation methods for the braking process. Moreover, the model makes it possible to study changes in kinematic parameters, power parameters, and energy parameters of HSMT under various conditions of a(..)

CONDITION FOR APPLICATION OF LOGISTIC PRINCIPLES IN PRACTICE OF URBAN PUBLIC PASSENGER TRANSPORT IN THE CITY OF OMSK

Sergey MOCHALIN/ Mariya KASPER/ Oleg NIKIFOROV/ Grigory LEVKIN

The task of increasing efficiency and quality of public transport has gotten special acuteness for large cities of Russia in connection with expansion of service by commercial carriers. There have no works done on the city of Omsk, where the transport system has its own characteristics. In this paper, characteristics of Omsk urban public transport are researched. The scheme that clearly demonstrates what factors have a negative impact on the development and functioning of the Omsk passenger tran(..)

INCREASING REDUCTION OF CO2 EMISSION IN HYBRID VEHICLES

Zbigniew ŁUKASIK/ Jacek KOZYRA/ Aldona KUŚMIŃSKA-FIJAŁKOWSKA

This article concerns the issue of reduction of CO2 emission in hybrid vehicles. External lighting through LED technology was applied to show additional CO2 savings in these vehicles. The authors propose for hybrid vehicles of M1 category: conditions of testing external lights, research equipment with measuring system and measuring method in order to determine energy savings obtained by application of external LED light. It enables to calculate saving of CO2 emission and estimate potential energ(..)

FREE-FARE PUBLIC TRANSPORT IN THE CONCEPT OF SUSTAINABLE URBAN MOBILITY

Robert TOMANEK

The dynamic development of cities based on the role of the car in addressing transport needs leads to a reduction of mobility, as well as to an increase in external costs generated by the transport system. This problem can be solved thanks to the sustainable mobility concept, in which transport needs are limited at the stage of planning spatial development and then covered by public transport as well as by cycle and pedestrian journeys. This article identifies arguments justifying the implementa(..)

LASER WELDING WITH MICRO-JET COOLING FOR TRUCK FRAME WELDING

Jan PIWNIK/ Bożena SZCZUCKA-LASOTA/ Tomasz WĘGRZYN/ Wojciech MAJEWSKI

The aim of this paper is to analyse the mechanical properties of the weld steel structure of car body truck frames after laser welding. The best welding conditions involve the use of proper materials and alloy elements in steel and filer materials, in addition to welding technology, state of stress and temperature of exploitation. We present for the first time the properties of steel track structures after laser welding with micro-jet cooling. Therefore, good selection of both welding parameters(..)

AN ANALYSIS OF THE ITALIAN RO-RO AND RO-PAX NETWORK IN THE YEARS 2008-2015

Marino LUPI/ Alessandro FARINA/ Antonio PRATELLI/ Letizia BELLUCCI

In this paper, the development of Motorways of the Sea (MoS) services offered at Italian ports from 2008 to 2015 is analyzed. In particular, a detailed research on MoS routes calling at Italian ports in the year 2015 is carried out; within MoS routes: ropax and only cargo ro-ro services are identified. MoS routes in the year 2015 are compared with those in the years 2008, 2010 and 2012. The study highlights two main aspects. First, the great majority of MoS routes in Italy are ro-pax ones: ro-ro(..)

CHARACTERISTIC OF A CRITICAL NETWORK ARC IN A SERVICE SYSTEM

Jaroslav JANÁČEK/ Marek KVET

Vulnerability of a transportation network influences, importantly, the function of public service systems constituted on the network. To be able to study the importance of an individual network arc for proper functionality of the system, we suggested a characteristic function of the arc transit time elongation together with its upper and lower estimations. We also suggested and verified an algorithm that enables the determination of parameters of the characteristic estimation, and we provide a r(..)

A STUDY OF THE INFLUENCE OF SOME EXPLOITATION FACTORS ON THE ATV STABILITY

Georgi KADIKYANOV/ Iliyana MINKOVSKA/ Gergana STANEVA

An original survey among ATV riders concerning the conditions in which they lost stability is conducted. The coordinates of the center of gravity of the ATV by riders with different Body Mass Indexes are determined. A simulation program on base mechanic–mathematical model to study the ATV’s motion is used. In this base the critical sideslip velocities and critical lateral overturn velocities of ATV at various riders’ Body Mass Index, curve radius and grip coefficients were calculated. The result(..)

SELECTING A LOGISTICS SERVICE PROVIDER: A DEFINITION OF CRITERIA THAT CONSIDER THE REQUIREMENTS OF AN EXTERNAL COMPETITIVE ENVIRONMENT

Patricija BAJEC/ Danijela TULJAK-SUBAN

A large number of criteria, the very diverse use of terminology and different classifications of criteria used to select a logistics service provider (LSP) reflect the lack of consensus in defining criteria. Moreover, whether the criteria are consistent with external requirements has not been analysed, which are vitally important for the success and competitiveness of the supply chain. This paper therefore presents a carefully prepared and evaluated classification system of criteria aligned with(..)
