APPLICATION OF EYE-TRACKING TECHNOLOGY AS A DIAGNOSTIC TOOL FOR ASSESSING FLIGHT OPERATORS. PART 2: A STUDY OF QUALITIES IMPORTANT FOR OPERATORS IN THE AVIATION INDUSTRY

Olga ARINICHEVA/ Natalia LEBEDEVA/ Aleksei MALISHEVSKII

This paper is based on the results of an experiment aimed at studying attention distribution and switching among students using a stationary eye-tracking device. The hypothesis was that the operator’s distraction tolerance should be influenced by his or her general mental strength; temperament, which is a derivative of the characteristics of the nervous system; and the level of intelligence, as a general indicator of the state of the nervous system. In addition, the paper discusses the results o(..)

RISK AND HUMAN FACTOR IN CARRIAGE OF DANGEROUS GOODS BY ROAD

Sylwia BĘCZKOWSKA/ Włodzimierz CHOROMAŃSKI/ Iwona GRABAREK

Authors in the article present an original method of risk assessment, taking “human errors” into account in its assumptions, filling an existing methodological gap in this field of study. This article presents a general concept of a method: estimating risk assessment and modeling human factors as the main cause of a road accident. Fuzzy logic techniques have been used to generate the value of the parameter characterizing the human factor. The authors’ “band” model is used in the calculation of t(..)

EVALUATION OF THE INFLUENCE OF THE PERCENTAGE OF COPPER CONTENT ON THE PHYSICAL AND CHEMICAL PROPERTIES OF THE FRICTION MATERIAL

Andrzej BORAWSKI/ Wojciech TARASIUK/ Eliza BORAWSKA/ Bożena SZCZUCKA-LASOTA/ Michał KRZYSZTOFORSKI

Copper is one of the main components of friction materials used in vehicles’ brake systems. It is mainly used due to two features: good thermal conductivity and lubricity. Unfortunately, it is harmful no only to humans but also more to aquatic life. For this reason, there is an attempt to minimize its use. This paper presents the results of testing four groups of samples with different Cu contents (5, 10, 15, and 20%). Laboratory tests were performed using calorimetry, hot wire method, and pin-o(..)

THEORETICAL BASES OF IMPREGNATION WITHOUT PRESSURE OF MELIORANTS AND THE APPLICATION OF THEIR FEATURES IN PRACTICE OF FIXING MOBILE SANDS

Makhamadjan MIRAKHMEDOV

Desert sand is subject to deflation, which during the construction and operation of railways in the sandy desert leads to the filling of the railway track with sand and erosion of subgrade. To prevent this phenomenon, the surface of the sand is fixed with a binder, which is sprayed onto a deflated surface. The penetration of the working composition of the binder due to the characteristics of grinding is accompanied by an uneven distribution of the substance, which is proposed to characterize the(..)

SMART PHOTONIC GUIDANCE SYSTEM FOR ROAD SAFETY

Dariusz LITWIN/ Adam CZYŻEWSKI/ Jacek GALAS/ Tadeusz KRYSZCZYŃSKI/ Piotr WIKLIŃSKI/ Barbara RYMSZA/ Leszek KORNALEWSKI

Despite the rapid and continuous progress in the construction of vehicles and accompanying improving road infrastructure, the road safety issue remains very serious. Especially, it concerns intersections and road junctions where nearly 30% of road accidents take place. The paper is focused on a new intelligent path displaying support system to be installed on intersections of complex geometry combined with multiphase traffic lights. It consists of optical projection of two different horizontal s(..)

OVERVIEW OF SAFETY AT RAIL-ROAD CROSSINGS IN POLAND IN 2008-2018

Elżbieta MACIOSZEK/ Agata KUREK/ Bartłomiej KOWALSKI

The intersection of a public road with a railway line in one level, called a rail-road crossing, is a particularly dangerous place due to the traffic flows crossing it. The regulations give absolute priority to a rail vehicle over a public road user; in addition, significant differences in the masses and speeds of moving vehicles require traffic regulation consisting of adequate passage protection. To this end, the road on which motor vehicles is equipped with road signs informing drivers that t(..)

ANALYSIS OF PEDESTRIANS’ SIDEWALK SERVICE

Cut MUTIAWATI/ Fitrika Mita SURYANI/ Ruhdi FAISAL/ M. AHLAN

The presence of sidewalks is very important to support the safety, comfortability, and activities of pedestrians in CBD (Central Business District). Therefore, this study was conducted to analyze the service quality of the pedestrian lanes in two CBDs of Banda Aceh City using the Importance-Performance Analysis (IPA) method. The results showed most of the service quality variables of the sidewalks are in quadrant A (concentrate here), followed by C (low priority), D (possible over-skill), and B (..)

DRIVING STYLE ANALYSIS AND DRIVER CLASSIFICATION USING OBD DATA OF A HYBRID ELECTRIC VEHICLE

Andrzej PUCHALSKI/ Iwona KOMORSKA

Ensuring the effectiveness of adaptive algorithms for advanced driver assistance systems (ADAS) requires online recognition of driving styles. The article discusses studies carried out during real driving cycles based on the GPS parameters and OBD system data of a hybrid vehicle. The work focuses on the search for measures of the speed and acceleration signals of the car and the measures determined on their basis that best describe the driving style responsible for the vehicle traffic safety and(..)

MULTI-CRITERIAL EVALUATION OF ELECTRONIC PAYMENT SYSTEM VARIANTS AND EVALUATION OF RESULTS OF AN EMPIRICAL RESEARCH FOCUSED ON AN ELECTRONIC PAYMENT SYSTEM

Eva BRUMERCIKOVA/ Bibiana BUKOVA/ Henryk KOMSTA/ Iwona RYBICKA

While choosing an electronic payment system intended for an immediate communication of a user (passenger) with an electronic terminal of a service provider (carrier), it is necessary to respect system parameters of presented technologies (NFC, EMV, and ABT). The methodology of choosing an electronic payment system within public transport may be divided into three steps as follows: • outlining criteria for variants evaluation, • multi-criterial evaluation of variants, and • evaluation of empirica(..)

MOVING OBJECT DETECTION IN CAR TRAFFIC WITH IMPLEMENTATION OF OPTICAL SENSORS

Piotr SZABLATA/ Paweł ŁĄKOWSKI/ Janusz POCHMARA

In this investigation, the problem of moving object detection - without any knowledge - is classified. It describes a technique that will allow real-time localization with usage of IR sensors. The proposed algorithm is simplistic, and in the future, it might be implemented into any vehicle, premium or entry level. It is guided by AI that must calculate its next moves in the blink of an eye without user noticing any delays. The main problem of moving object recognition was extraction of proper fe(..)

The article is devoted to the issue of the negative effect of delays in the movement of special rescue vehicles on the effectiveness of their mission. The dependence of the area of fire on the delay of the arrival of firefighters using a fire-rescue vehicle is shown. The cascading graph of route options of special vehicle movement to the place of an emergency call is given. The algorithm of the optimal route choice of the special vehicle motion with given projected delays is offered. Based on th(..)

Mortality caused by road accidents is a significant problem for most countries, including Poland, where approximately 2,900 people die each year, and another 37,359 are injured. Research in this area has been conducted on a large scale. One of the most important elements is the evaluation of factors leading to fatalities in road accidents, which is also the goal of this article. The analysis was based on data on road accidents from the Mazowieckie Voivodeship, which is characterized by one of th(..)
