A CASE STUDY ON PERCEPTIONS OF PUBLIC TRANSPORTATION IN THE EASTERN PROVINCE OF SAUDI ARABIA

Helen Palmer PETERSON/ Zulfat AL KASSIM

The Eastern Province of the Kingdom of Saudi Arabia (KSA) is home to almost 5,000,000 people and is a major contributor to Saudi Arabia’s economic strength. The area has experienced population growth of about 3.5% per year and rapid urbanization over the past few decades. With this increase in population has come a significant escalation in automobile traffic, which, in turn, has contributed to poor air quality in the province. Two of the major cities in the area were listed on the World Health (..)

FATIGUE AND SLEEPINESS DURING LONG-DURATION DRIVING: A PRELIMINARY STUDY AMONG INDONESIAN COMMERCIAL DRIVERS

Hardianto IRIDIASTADI/ Ibrahim ABDURRAHMAN/ Maya PUSPASARI/ Herman Rahadian SOETISNA

Fatigue and sleepiness are two major factors that have been reported to contribute to road crash and accidents in Indonesia. Fatigue among commercial drivers is probably a common phenomenon, particularly during long-duration driving. This study aimed at characterizing fatigue and sleepiness during long-duration driving. Nine commercial drivers were recruited in this field study and were requested to drive a multipurpose vehicle for three trips back and forth between two major cities. Each trip w(..)

COLLISION MODEL SIMPLIFICATIONS IN THE DYNAMIC ANALYSIS WITH THE SDC METHOD

Piotr ALEKSANDROWICZ

The number of motor vehicles in the European Union (EU) is constantly increasing, which is causing an increase in the traffic volume. This, in turn, boosts the economic development of the EU member states. However, an increase in traffic volume leads to road collisions and accidents, which lead to high repair costs. Some accident victims report fake vehicle damage to extort money for repairs. There are criminal groups that stage accidents for this purpose; thus, these claims are very difficult t(..)

APPLICATION OF THE CHOSEN MULTI-CRITERIA DECISION-MAKING METHODS TO IDENTIFY THE AUTONOMOUS TRAIN SYSTEM SUPPLIER

Ondrej STOPKA/ Mária STOPKOVÁ/ Vladimír ĽUPTÁK/ Srećko KRILE

This paper addresses an application of the specific methods of multi-criteria decision analysis to specify the appropriate supplier of an autonomous train in a certain production–distribution company. This company identifies three potential suppliers dealing with the development and purchase of autonomous train systems. In terms of the multi-criteria decision analysis, the WSA method, the Scoring method and the TOPSIS method were used to define a suitable compromise solution. To apply each metho(..)

SIMULATION OF DYNAMIC PROCESSES OF INTERACTION OF CAR AND RAILWAY TRACK DURING TRAIN PASSAGE OF CURVED SECTIONS OF THE TRACK

Gabit BAKYT/ Seidulla ABDULLAYEV/ Nurgul SULEYEVA/ Amandyk YELSHIBEKOV/ Zhanerke SEIDEMETOVA/ Zhadyra SADVAKASSOVA

In this article, the considered principles for the development of calculation schemes and the subsequent formation of vibration equations are a special case of classical simulation of motion in space of solid body systems connected in space by kinematic connections. This approach is useful with limited computational capabilities and an assumption of the relatively small body movements inherent in railway crew bodies, and reduces the task of motion research to analysis of fluctuations. Various de(..)

PROBLEMS OF ANALYST COMPETENCY FORMATION FOR MODERN TRANSPORT SYSTEMS

Svetlana LYAPINA/ Valentina TАRASOVA/ Marina FEDOTOVA

Intelligent information and analytical basis of a modern transport system is a prerequisite for efficient functioning of the digital economy. Modern transport systems are based on new intelligent technologies and new organizational principles, which is why the functions and competences of specialists in transportation are changing very rapidly. This paper substantiates the need and reveals the content of new competencies of specialists for modern transport systems, which should be ready to take (..)

NOISE CONTROL OF THE BEGINNING AND DEVELOPMENT DYNAMICS OF FAULTS IN THE RUNNING GEAR OF THE ROLLING STOCK

Telman ALIEV/ Tofig BABAYEV/ Tahir ALIZADA/ Narmin RZAYEVA

In contrast to traditional systems for monitoring fault of the running gear of the rolling stock, this paper proposes a technology of noise control at the onset of defects. The authors consider the possibility of creating an intelligent system that can perform noise diagnostics with the indication of the beginning of the latent period of the initiation of typical defects preceding faults. To this end, using the noise technology, sets of reference informative attributes are created in the trainin(..)

INVESTIGATING THE ECONOMIC EFFICIENCY OF WASTE COLLECTION AND TRANSPORTATION – CASE STUDY FOR URBAN AND RURAL MUNICIPALITIES IN POLAND

Mariusz WALA/ Piotr NOWAKOWSKI

This article presents the results of the analysis of waste collection in selected rural and urban municipalities in the Silesian Voivodship in Poland in the years 2014-2018. A new approach has been presented for the evaluation of the economic efficiency of the waste management system including all costs and revenues both for the local administration and the waste collection company in a circular economy context. The results include the impact of significant factors affecting the total cost of co(..)

STEEL RELIEVING CONSTRUCTIONS IN MINING AREAS AS TEMPORARY OR PERMANENT RAILWAY BRIDGES

Piotr BĘTKOWSKI

This article describes three examples of bridge-type relieving constructions located on railway lines in the areas of active mining exploitation. It discusses how to take into account mining influences and how to support a temporary relieving construction on the railway embankment. This article discusses the incorrect solutions and their consequences. The first example involves the protection of train traffic continuity during the replacement of bridge span under an intensively used railway line(..)

MULTI-CRITERIA CHOICE OF THE REGION FOR THE CONSTRUCTION OF A LOGISTICS CENTER BASED ON AHP: CASE STUDY FOR KAZAKHSTAN

Aleksander SŁADKOWSKI/ Bagdat TELTAYEV/ Madina IZTELEUOVA

The current state of the regional market of transport and logistics services in Kazakhstan is characterized by a disparity between the increasing demand for logistics services and the lack of logistics capacity. In this article, the authors propose a method for determining the most promising areas of the Republic of Kazakhstan for the construction of a logistics center, based on the Analytic Hierarchy Process (AHP).

PROBLEM OF AERODYNAMIC INTERACTION OF TRAFFIC STREAMS

Valerii SOLODOV

This study presents a model of continuous oncoming traffic flows of vehicles along highways. The flow of atmospheric air and impurity particles is modeled numerically based on unsteady Reynolds-Averaged Navier–Stokes equations using the MTFS® authoring software. Detailing of the flow patterns allows arbitrary length regions of periodicity, taking into account a crosswind. The examples provided demonstrate some of the results of the aerodynamic interaction of two oncoming columns of vehicles. The(..)

THE OPTIMIZATION OF TRUCKS FLEET SCHEDULE IN VIEW OF THEIR INTERACTION AND RESTRICTIONS OF THE EUROPEAN AGREEMENT OF WORK OF CREWS

Myroslav OLISKEVYCH/ Stepan KOVALYSHYN/ Myron MAGATS/ Viktor SHEVCHUK/ Oleh SUKACH

The importance of compliance with the schedule of work of road trains on the highway transport network of the European Union is shown. The possible options for work and rest modes for truck drivers on international routes have been analyzed. A model for optimizing the truck fleet operation plan has been developed. This model has two levels, that is, the general graph contains subgraphs designed with incompatible vertices to determine the active and shortest schedule. Each of the subgraphs reflec(..)
