DETERMINATION OF THE INFLUENCE OF INFRASTRUCTURAL AND ECONOMIC FACTORS ON THE VOLUME OF FREIGHT TRANSPORT ON RAILWAY LINES IN POLAND

Wojciech KAMIŃSKI

This article assesses the effect of factors, such as the number of sidings, the number of station holds, and the occurrence of transit traffic on the volume of freight transport on railway lines in Poland. The volume of freight transport on a railway line was expressed by the operational work done by freight trains running on this line and the transported freight mass by them. Most often the effect of factors affecting on the volume of transport is assessed by a team of experts. In this analysis(..)

ANALYSIS OF THE POSSIBILITY OF REDUCING EXTERNAL COSTS OF TRANSPORT WITHIN LAND-SEA TRANSPORT CHAINS ON THE EXAMPLE OF ZACHODNIOPOMORSKIE VOIVODESHIP, POLAND

Andrzej MONTWIŁŁ/ Krystian PIETRZAK/ Oliwia PIETRZAK

Land-sea transport chains constitute a key part of the Europe’s economy, as a significant part of its trade is carried out using sea transport. Transport, storage, or delivery processes carried out within these chains are characterized by specified economic and technical efficiency, which often does not take into consideration the external costs these processes generate. Therefore, there is a need for further changes in the European land-sea transport chains, the aim of which should be a further(..)

THE INFLUENCE OF EXTERNAL ENVIRONMENT TO THE FERRY LINES AND MARINE PASSENGER TERMINALS

Srećko KRILE/ Nikolai MAIOROV

Marine passenger ports are integrated into the transport systems of cities and regions today. If there are sufficient developed mathematical forecasting models in the class of polynomial models, probability series, and a number of others, then the models describing the influence of the external environment on ferry market are not sufficient. The developed scheme of interaction between the participants of the cruise market and the mathematical model of the port as a technical system is presented (..)

OPPORTUNITIES TO IMPROVE THE EFFICIENCY OF THE “GWAREK 1200” BELT CONVEYOR

Grzegorz PERUŃ/ Bogusław ŁAZARZ/ Tadeusz OPASIAK

The article presents the results of research of the Gwarek 1200 belt conveyor. The work aimed to determine the possible benefits of changing the type of rollers used. It was expected that the change of the rollers from N-type to C-type will reduce the costs of energy consumed by the conveyor drive system. This part of the research was carried out in a hard coalmine at the level of 665 m. The test was given the entire power unit in terms of the starting power demand and rated power in real time. (..)

THE USE OF THE ROADLOAD APPLICATION IN GEOGRAPHICAL STUDIES OF FLOWS GENERATED BY INDIVIDUAL MODES OF TRANSPORT

Marta BOROWSKA-STEFAŃSKA/ Michał KOWALSKI/ Szymon WIŚNIEWSKI/ Adam DOMAGALSKI

The purpose of this article is to present the authors' own software for predicting changes in the density and directions of traffic flows and to compare overall results of research on transport accessibility with the results returned in the study of transport accessibility conducted with the software (isochronic accessibility). Developed for research purposes, the authors' application is based on Dijkstra's algorithm, which is classified as one of the greedy ones and does not always return optim(..)

A REVIEW OF APPROACHES TO THE STUDY OF WEATHER’S EFFECT ON ROAD TRAFFIC PARAMETERS

Dominika JARMUŻ/ Jerzy CHMIEL

The paper describes selected research achievements into the effect of weather on road traffic from the perspective of various combinations of traffic characteristics and meteorological conditions. Studies to date have focused on different traffic parameters and changes in them as a consequence of weather variety. In making a comparative analysis, researchers identify the optimal weather conditions for road traffic and driver perception. Research in this field is conducted using a variety of data(..)

INNOVATION IN THE WINTER ROAD MAINTENANCE AND ITS ECONOMIC JUSTIFICATION

Stefan SEDIVY/ Zuzana FLORKOVA/ Gabriel GASPAR/ Juraj DUDAK/ Peter FABO

In general, it can be presented that winter road maintenance costs are rising due to increasing mobility, rising of salaries, and technological needs. For this reason, it is necessary to bring innovations into these processes. The greatest space is in the area of weather forecasting, which is a trigger for maintenance activities in the form of reducing black ice or snow removal. Road administrators use predictive services as a standard to obtain critical atmospheric temperature and weather data (..)

CARGO SECURING – COMPARISON OF THE SELECTED TRUCKS

Martin VLKOVSKÝ/ Petr VESELÍK

The paper deals with a comparison of shocks (values of acceleration coefficients and inertial forces) of two types of vehicles (T-810 and T-815 MK IV) during transport experiments on a motorway. The measurement was performed using an OM-CP-ULTRASHOCK-5 three-axial accelerometer with a datalogger and calibration certificate. The goal of the paper is to accept or reject a hypothesis of the existence of a statistically significant difference between the values of the acceleration coefficients gener(..)

P&R PARKING AND BIKE-SHARING SYSTEM AS SOLUTIONS SUPPORTING TRANSPORT ACCESSIBILITY OF THE CITY

Elżbieta MACIOSZEK/ Agata KUREK

The transport accessibility of cities decreases with the increase in road traffic. Planners, traffic engineers, and road managers are looking for solutions that will reduce congestion on city streets without limiting transport accessibility to the city center. The article presents an overview of solutions used in Poland and abroad that aim to encourage people who travel by car to the city center to use other means of transport. The solutions were identified that can contribute to reducing road t(..)

AN ASSESSMENT OF AIRPORT SUSTAINABILITY MEASURES: A CASE STUDY OF POLISH AIRPORTS

Dariusz TŁOCZYŃSKI/ Małgorzata WACH-KLOSKOWSKA/ Rodrigo MARTIN-ROJAS

Air transport, like every economic branch, strives for development. Air traffic is growing dynamically, which means that the natural environment is increasingly being polluted each year. Therefore, entities operating in the air transport sector should care for the environment. One of these entities - airports - introduces many restrictions for aircraft with high CO2 (carbon dioxide) emissions. At the same time, they introduce many ecological activities. Every year, also at the largest Polish air(..)

VERIFICATION OF THE CONDITIONS FOR WHIPLASH-TYPE INJURIES WITH THE SDC METHOD USING THE SRS-AIRBAG SYSTEM ACTIVATION PARAMETERS

Piotr ALEKSANDROWICZ/ Iwo ALEKSANDROWICZ

A problem of car insurance frauds usually refers to reporting non-existent car crash circumstances to acquire the funds required for a car repair. However, the problem is not limited only to this kind of costs. Recently, numerous damage claims connected with spine trauma caused by rear-end collisions have been reported. These are the so-called whiplash injuries caused by a rear impact. Such damage is difficult to verify and hence a necessity to use more effective claim verification methods. An a(..)

ASSESSMENT OF THE INFLUENCE OF SELECTED FACTORS ON THE PUNCTUALITY OF AN URBAN TRANSPORT FLEET

Małgorzata GRZELAK/ Anna BORUCKA/ Andrzej ŚWIDERSKI

Urban transport systems operate according to fixed, strict timetables, which requires high timeliness and technical readiness of the fleet. Therefore, this article proposes a detailed study of the punctuality of the public transport system using a multiple regression model for the main modes of transport (trams, buses, and Warsaw Metro). The analysis made it possible to go beyond the framework of the overall assessment and to identify the factors that have a significant effect on the punctuality(..)

ESTIMATED ASSESSMENT OF THE POTENTIAL IMPACT OF DRIVERASSISTANCE SYSTEMS USED IN AUTOMATED VEHICLES ON THE LEVEL OF ROAD SAFETY IN POLAND

Małgorzata PĘDZIERSKA/ Piotr PAWLAK/ Mikołaj KRUSZEWSKI/ Samantha JAMSON

Strengthening road safety in the face of the enormous development of the automotive in recent decades is crucial. The safety benefits of automated vehicles are paramount. Automated vehicles have the potential to remove human error in road traffic, which will help protect drivers and passengers, as well as pedestrians and bicyclists. The carried-out forecasts are pioneering for Polish road traffic conditions. In England, studies have been carried out to determine the estimated impact of autonomou(..)
