Velizara PENCHEVA/ Asen ASENOV/ Dimitar GROZEV/ Ivan GEORGIEV/ Pavel STOYANOV

For this study, an analysis of a system of transport nodes of the railway and bus service transportation was carried out. A principal scheme of a transport node in typical cities for Bulgaria and a sample flow chart are presented. The categories of basic requirements for transport nodes in cities are also defined. On the basis of a railway system and bus transport nodes in the city of Ruse, Bulgaria, research on the interaction of the system with the mass urban passenger transport has been condu(..)

SIMULATION OF THE ROUTE NETWORK AND FERRY TRAFFIC INTENSITY BASED ON THE PROCESS OF DISCRETIZATION AND CIRCOS PLOT INTENSITY DIAGRAM

Nikolai MAIOROV/ Vladimir FETISOV / Srećko KRILE/ Darijo MISKOVIC

Today, one of the main important tasks is to analyze the states of achievement related to the required levels for marine passenger terminals and their route networks, depending on the influence of the external environment (based on the discretization of processes). This proposal is relevant both to increase the passenger traffic and to change the route network of ferry lines. There is an uneven congestion of individual directions of ferry lines and passenger terminals, which determines the need (..)

FUZZY EXPERT SYSTEM FOR ADAPTIVE VESSEL TRAFFIC CONTROL ON ONE-WAY SECTION ON NAVIGABLE CANAL

Vladimir BUGARSKI/ Todor BAČKALIĆ/ Željko KANOVIĆ/ Filip KULIĆ/ Miloš ZEKOVIĆ

This paper analyses the management process of the vessel traffic control on one-way section on navigable canal with the adaptive time-sequential filter (traffic lights). One-way section on canal significantly decreases waterway capacity and requests special attention in control and regulation of the vessel traffic. The vessel traffic is a stochastic variable, and the vessel traffic control needs to be flexible and adaptive in order to achieve the required traffic flow with minimal delays. On the(..)

THE IMPACT OF CHANGING THE FUEL DOSE ON CHOSEN PARAMETERS OF THE DIESEL ENGINE START-UP PROCESS

Jacek CABAN/ Paweł DROŹDZIEL/ Piotr IGNACIUK/ Paweł KORDOS

For internal combustion engines, many faults relating to the combustion process can occur, which affect the engine technical condition, its electrical equipment, the natural environment, etc. This article presents the results of the influence of the regulatory factor, which was the fuel dose (3 dose values), on selected parameters of the start-up process at constant settings of other control parameters (fuel injection advance angle and injection pressure). The tests of the start-up process were (..)

A NETWORK DESIGN OPTIMIZATION PROBLEM FOR RO-RO FREIGHT TRANSPORT IN THE TYRRHENIAN AREA

Gianfranco FANCELLO/ Patrizia SERRA/ Simona MANCINI

Roll-on Roll-of (Ro-Ro) transport is one of the primary options EU policy is focusing on for developing intermodal transport and MOS initiatives, aimed at reducing road transport (especially trucks). In line with EU guidelines, this study proposes an integrated and optimized network scheme for the maritime Ro-Ro freight services currently operating in the Italian Tyrrhenian area to improve the overall supply of shipping services. The methodological approach used is based on the integration of th(..)

SAFERWHEELS PROJECT: STUDY ON SCENE OF ACCIDENT WITH POWERED TWO-WHEELER AND BICYCLE

Katarzyna SICIŃSKA/ Agnieszka KRUPIŃSKA

The article presents results and the way of providing research project on indepth crash study on scene of accidents of 385 Powered Two-Wheelers (motorcyclists, motorists) and 116 bicycles in the European Union in 2014-2017. The main concern of an in-depth crash study at the site of a traffic accident is to collect data on vehicles, roads, and drivers, including interviews with participants. Data descriptive statistics have been used to underline the dominant factors that appear most frequently i(..)

EXPERIMENTAL MONITORING AND NUMERICAL MODELING OF THE THERMAL REGIME OF SELECTED TRACK SUBSTRUCTURES

Libor IŽVOLT/ Peter DOBEŠ/ Stanislav HODÁS

The initial part of the paper characterizes major research activities at the Department of Railway Engineering and Track Management (DRETM), Faculty of Civil Engineering, University of Žilina. Subsequently, it outlines the state of art in the field of track substructure dimensioning for the non-traffic load in Slovakia and abroad. The second part of the paper deals with the method of collecting input parameters for numerical modeling of the track substructure freezing using SoilVision software. (..)

ASSESSING THE TRANSIT CAPACITY OF PORT SHUNTING YARDS THROUGH DISCRETE SIMULATION

Florin RUSCA/ Mihaela POPA/ Eugen ROSCA/ Aura RUSCA/ Mircea ROSCA/ Oana DINU

The port shunting yards are developed inside the area of the ports. The main activities are to receive the freight trains from the hinterland, to shunt the freight wagons according to their final destinations from the area of the port, to receive the wagons from maritime terminals, to accumulate wagons according to their destination, and to depart the freight train to the hinterland. So, it is important for port administration to have good methods to evaluate the transit capacity of port shuntin(..)

DEVELOPMENT OF A LOW-COST MEASUREMENT SYSTEM TO DETERMINE 3-DIMENSIONAL PEDAL LOADS DURING IN-SITU CYCLING

Sien DIELTIENS/ Jordi D’HONDT/ Marc JUWET/ Mark VERSTEYHE

As increasingly more bicycles are equipped with electrically powered pedal assistance, they can become the solution for the continuous congestion that threatens Europe. Pedal assistance decreases the effort, though cyclists often experience sores that occur at the low back, knees and bottom area. The risk of injuries is predominantly determined by the pedal technique, which is highly dependent of bicycle design, seat type and cycling posture. The optimal cycling technique and the relation to the(..)
