Opis:
People’s ever-increasing needs encourage designers of various vehicles to search for solutions that will provide the most comfortable internal environment conditions. Currently, partly due to the COVID-19 threat, many people use their individual cars to travel to work, college, shops, trips, and holidays. Proper internal air parameters that need to be maintained in vehicles are critical in the sum-mer. The article discusses the thermal comfort of four passengers of a modern car produced in 2017to verify if contemporary production technology can successfully meet the thermal needs of people under actual conditions in the Polish climate. For this purpose, five temperature values were tested:20oC, 22oC, 24oC, 26oC, and 28oC for the car located in the shade and sun. In addition, the Testo 400meter was used to control and measure the internal parameters, and questionnaires were used to find out about the thermal impressions of the respondents. The research was carried out in July when the air temperature in Poland was high

Opis:
In this study, a mathematical method is proposed for calculating the concentration field of air ions of different polarities and dust levels in the passenger compartment, taking into account the geometry of the passenger compartment and seats, shelves, and other internal elements of the passenger compartment. The method also takes into account changes in the rate of the air flow ventilation, the location and number of ionizers, and sources of positive ions and dust, taking into account their different intensities and locations. On the basis of a numerical model for this method, software has been developed that allows users to carry out computational experiments without requiring much time for calculation. Based on the results, the optimal location of the ionizer in the passenger compartment of the car was determined to ensure comfortable conditions for the stay of passengers, which favorably affects their health. It has been found that the presence of two ionizers is optimal for creating comfort in the car with an ionization intensity of Qn= 0.47 ×1010 ions/s located at the top of the car. If there is one ionizer located on the dashboard or at the top of the car with a higher ionization rate than ions/s, it is not possible to simultaneously provide optimal ionization parameters for passengers in the front and rear seats of the car.

Opis:
Unexpected delay on freeways is the prime cause of dissatisfaction in road users. Increasing traffic, adverse environmental conditions, accidents, time, season, location and many more factors influence travel time and cause delay. There is no direct method to estimate delay. It is calculated from trip time estimates. Thus, it is a very big challenge for transportation professionals to develop a model that accurately estimates the trip time for a trip at a particular time, by a specific mode of transport. Subsequently, the reliability of the delay calculated from those trip time estimates is often doubtful. Further, the measurement of delay using the trip time data is another big thing. This paper is a step toward measuring the delay in an accurate way using travel time reliability measures. The study was conducted on the two modes of public transportation (City bus and Auto) in an urban corridor of length 16.3 km, in Hyderabad city, India. In this study, a license plate survey was conducted for data collection, travel time-based statistical analysis was employed for estimation of trip time and by making use of travel time measures, the delay was measured. The approach was validated graphically to portray its accuracy.

Opis:
Transport is one of the most burdensome negative sources affecting the natural environment. Long-term exposure of the body to exhaust pollution can cause health problems and, in the worst case, even lead to death. In addition to exhaust emissions, traffic noise is another equally important issue. Due to its nature, variability over time or the design diversity of vehicles in the traffic flow, it is a phenomenon difficult to define. Like exhaust pollution, it affects people's health and quality of life. In addition to its direct impact on the human physical system, it can also cause psychosomatic disorders, which is why a detailed analysis of road noise taking into account the real operation of the vehicle is so important. The paper presents the basic concepts related to the problem of traffic noise in the world, determines the sources of noise in vehicles and the methodology of conducting acoustic road tests. At the final stage of the scientific paper, methods of reducing excessive noise levels in large urban agglomerations were also presented, and the effectiveness of using noise barriers on selected parts of the city road network using proprietary acoustic tests was assessed.

Opis:
W artykule omówiono proces projektowania innowacyjnej tymczasowej bariery ochronnej spełniającej wymagania normy EN 1317 i zapewniającej poziom bezpieczeństwa T1/W1. Proces projektowy wspomagany był przez analizy teoretyczne, modelowe, badania laboratoryjne i symulacyjne (MES). Symulacja numeryczna testów zderzeniowych dała zbliżone rezultaty co do długości kontaktu pojazdu podczas zderzenia, prędkości pojazdu po zderzeniu, deformacji bariery, rozkładu uszkodzeń oraz czasu uderzenia, do wartości uzyskanych w rzeczywistych testach zderzeniowych przeprowadzonych na specjalnym torze. Zachowanie systemu bariery podczas symulacji zderzenia w programie LS-DYNA zostało dobrze odwzorowane. Zaprojektowana bariera po rzeczywistych testach zderzeniowych uzyskała certyfikat potwierdzający wymagane dla danej kategorii barier parametry i została wdrożona do produkcji.
The paper presents a design procedure for an innovative temporary traffic barrier according to EN 1317 with a safety level T1/W1. The design involved theoretical analysis, modeling, lab tests and simulations (FEM). Numerical simulation of the crash tests accurately predicted the contact length for a vehicle, vehicle speed after crash, deformation of the barrier, location of deformation and time. The crash test was carried out on a designated test track. The simulated behavior of the barrier using LS-DYNA program was confirmed by tests. After tests, the designed barrier received an official certification required for commercial implementation.

Opis:
The stability and smoothness of rolling stock running could be defined accurately by universal Sperling's comfort index. The divergences of variation of Sperling's comfort index of a passenger car under specific operating conditions of running gear are examining in this paper. Numerical simulations of a passenger car running with independently rotating wheels under various conditions have been performing. Gained results showed that divergences of the Sperling's comfort index variation are particularly significant due to running gear component oscillations in the horizontal plane (lateral direction). A field experiment of a passenger car with a solid (traditional) wheelset with a flat running surface proved this hypothesis. The obtained results of this experiment confirmed this assumption. Therefore, the study of the regularities of lateral oscillations of a passenger car is the logical direction of further research.

The aim of the article is to present the environmental effects of changes in material composition in selected internal combustion engines used in passenger cars using LCA analysis. The levels of energy consumption and emissions of pollutants related to material inputs occurring at the stage of engine production have been determined. The simplified LCA model presented in the paper shows the energy consumption and total CO2 and SO2 emissions on the basis of the mass of materials from which the engine is made. The research results presented in the paper give a picture of a modern passenger car engine on the basis of wear and the degree of recovery of materials used for its construction.

This paper presents the results of environmental footprints of the life cycle of electric passenger cars, with a current and future electric battery charging analysis in Poland. The shares of the sources of electricity generation in the energy systems of Poland in the years 2015–2050 were used to perform the chosen environmental footprints of current and future electric car battery charging. This article discusses the water and carbon footprints of electric passenger cars in Poland. The carbon footprint was determined usin the Intergovernmental Panel on Climate Change (IPCC) method. The water footprint was calculated using the Hoekstra method. The environmental footprints were provided by the SimaPro 8 package with the Ecoinvent 3 database. The obtained results showed that the carbon footprint and water footprints of electric passenger cars in Poland are primarily related to the type of electricity used to charge electric car batteries. The results showed that current and future carbon footprint indicators of electric cars in Poland are lower than those for petrol cars, but the water footprint indicators of electric cars are higher than those for petrol cars. In the case of petrol cars, the main determinant of the carbon footprint is direct emission during the exploitation stage and the main determinant of the wate footprint is car production.

Opis:
In the future, the simultaneous reduction of pollutant and CO2 emissions will require significantly enhanced powertrain functionalities that cannot only be adequately represented by the ICE (internal combustion engine) alone. Both automated transmissions and especially powertrain electrification can help to meet efficiently those extended requirements. The extended functionalities are no longer applied exclusively with the ICE itself ("Fully Flexible Internal Combustion Engine"), but distributed across the entire powertrain ("Fully Flexible Powertrain"). In addition, the powertrain will be fully networked with the vehicle environment and thus will utilize all data that are useful for emission and consumption-optimized operation of the ICE. Combustion engine and electrification often complement each other in a synergetic way. This makes it extremely sensible for the combustion engine to evolve in future from a "single fighter" to a "team player". If one compares the requirements of such an ICE with the definition of Industry 4.0, then there are extensive correspondences. Thus, it seems quite opportune to call such a fully networked combustion engine designed to meet future needs as “Internal Combustion Engine 4.0 (ICE 4.0)”. This even more so, as such a name can also be derived from the history: e.g. ICE 1.0 describes the combustion engines of the first mass-produced vehicles, ICE 2.0 the combustion engines emission-optimized since the 1960s and ICE 3.0 the highly optimized "Fully Flexible Combustion Engine", which currently offers a high torque and performance potential combined with low fuel consumption and pollutant emissions. In addition to further improvements in fuel consumption, the "Combustion Engine 4.0" offers such a low level of pollutant emissions that can best be described as "Zero Impact Emission". This means that such future ICE´s will no longer have a negative impact on the imission situation in urban areas. With the e-fuels topic, the ICE also has the potential to become both CO2- and pollutant-neutral in the medium and long term. This means that the ICE - also in passenger cars - will continue to be an essential and necessary cornerstone for future powertrain portfolios for the next decades.

Opis:
Almost every voyage culminates in a manoeuvre to berth the ship safely along a quay or wharf. During this phase a ship is affected by a number of factors, one of them being wind. This paper seeks to understand how wind affect a ship in regards of power consumption during berthing. A field study was conducted on a car passenger ferry, where every approach in one harbour was logged and analysed over a period of four months. The goal was to provide greater knowledge about energy usage and the study presents several interesting findings. It is estimated that power consumption is stable when the median wind speed is less than 4 m/s. Stronger winds have a significant effect on power consumption, e.g 17 m/s gives an 106,31% increase from calm conditions. Furthermore there is not discovered any correlation between consumption and wind direction in this study.

The article concentrates on road safety in Poland, which is one of the countries with a high number of fatalities in European Union. As the passenger cars are the mostly involved in traffic accidents with fatalities, this type of vehicles was analyzed to check relationship between age of the vehicle and its involvement in accidents with fatalities. This type of scientific analysis was made for the first time. For carrying out this research, a method of estimating passenger car fleet in motion in Poland was designed, as the official data were not updated and provided wrong information. The updated information on passenger car fleet when compared with that on the age of vehicles involved in road accidents with fatalities showed that the age of a vehicle has influence on the occurrence of road accidents in Poland. Presented data showed that the fact that people involved in accidents are at a higher risk of loss of life depends on the age of a vehicle. The data from analysis conducted between 2014 and 2015 showed that the risk of being killed increases with the age of the vehicle. Chances of the loss of life of people involved in accident participants are three times more in the case of more than 21 year old cars compared to 5 years old cars.

Opis:
Transport of passengers is carried out essentially using two types of vehicles: classic trains composed of a locomotive pulling passenger wagons or traction units (or multiple units). Both new and modernized rail vehicles must be subjected to, among others, brake system tests when being placed into service. The purpose of such tests is to check the correct operation of the brake system and to determine the actual brake performance. The method of determining the passenger wagon brake performance differs from the similar method for the train set, although the braking performance of both types of vehicles is eventually presented in the form of two parameters: the value of brake mass B expressed in tons and the percentage of braked mass λ, i.e. the ratio of braked mass to vehicle total mass, expressed as a percentage. The values of B and λ determined from the tests describing the brake performance serve to assess the brake performance of the train in operation, while railway traffic safety relies significantly on the correct understanding of their nature and their use. Unfortunately, it was observed that individual carriers interpret these values in different ways and describe them in various ways on vehicles that are ultimately operated on the same infrastructure. The article presents a proposal of a new, original, unified and transparent method of describing brake performance for electric multiple units, as well as its interpretation and application in railway operations, developed in the Brakes Workshop of the Railway Institute.
Przewozy pasażerskie realizowane są z wykorzystaniem zasadniczo dwóch rodzajów pojazdów: klasycznych pociągów złożonych z lokomotywy i ciągniętych przez nią wagonów pasażerskich lub zespołów trakcyjnych (ewentualnie pociągów zespołowych). Zarówno nowe jak i modernizowane pojazdy szynowe w trakcie procesu dopuszczenia do eksploatacji muszą zostać poddane m.in. badaniom układu hamulcowego. Celem takich badań jest sprawdzenie poprawności działania tego układu oraz wyznaczenie rzeczywistej skuteczności hamulca. Metoda wyznaczenia skuteczności hamulca wagonu pasażerskiego różni się od analogicznej metody dla zespołu trakcyjnego, mimo iż ostatecznie skuteczność hamulca obu rodzajów pojazdów przedstawiana jest w postaci dwóch parametrów: wyrażanej w tonach wartości masy hamującej B i procentu masy hamującej λ, czyli stosunku masy hamującej do masy pojazdu, wyrażonego w procentach. Wyznaczone w rezultacie badań wartości B i λ opisujące skuteczność hamulca służą w trakcie eksploatacji pojazdów ocenie skuteczności hamulca pociągu, a właściwe zrozumienie ich istoty i prawidłowy sposób posługiwania się nimi mają decydujące znaczenie dla bezpieczeństwa ruchu kolejowego. Niestety zaobserwowano, że poszczególni przewoźnicy na różny sposób interpretują te wartości i w różny sposób opisują je na pojazdach, które ostatecznie eksploatowane są na tej samej infrastruktur. W artykule przedstawiono opracowaną w Pracowni Hamulców Instytutu Kolejnictwa propozycję nowego, oryginalnego, ujednoliconego i przejrzystego sposobu opisywania skuteczności hamulca na elektrycznych zespołach trakcyjnych oraz jej interpretacji i stosowania w praktyce kolejowej.

Opis:
The subject of this article is a comparative analysis of exhaust emissions for: HC (hydrocarbons), CO (carbon monoxide), CO2 (carbon dioxide), NOx (nitrogen oxides) from a passenger vehicle and a motorcycle in laboratory conditions on a dynamometer station. The first vehicle category was represented by a compression-ignition engine with a displacement volume of 1.3 dm3 and a power of 66 kW. The exhaust aftertreatment system included a catalytic converter and a particulate filter. The second category was a motorcycle, equipped with an engine with a displacement of 0.7 dm3 and a maximum power of 55 kW. The two-wheeled vehicle was equipped with a three-way catalytic converter. Speeds were modeled on the European type approval test - NEDC (New European Driving Cycle). In order to conduct a comparative analysis of exhaust emissions and fuel consumption from vehicles of different categories, the obtained results were presented in the form of emissions converted into passenger-kilometers (g/pkm). The research used modern equipment belonging to the PEMS (Portable Emissions Measurement Systems) group of devices. The analyzes carried out enable the decision making on which vehicles have a greater environmental impact due to their exhaust emissions, taking into account the distance and the number of passengers carried.

Opis:
The purpose of this paper is to provide a comparative environmental life cycle assessment (LCA) of chosen internal combustion engine vehicles (ICEVs). It addresses an LCA of both petrol-fuelled and diesel-fuelled passenger cars. The analyses pertained to the carbon footprint and respiratory inorganics related to the cars in question, considered against the relevant system from cradle to grave. The comparative analysis has shown that the carbon footprint of a diesel-fuelled car is lower than that of a petrolfuelled car. However, the environmental indicators of respiratory inorganics induced by diesel-fuelled cars are higher than those attributable to petrol-fuelled cars. The main determinant of carbon footprint for the life cycle of these ICEVs is the direct atmospheric emission of carbon dioxide associated with their operation. The main determinants of respiratory inorganics for the diesel passenger cars’ life cycle are nitrogen oxide emission and car production. As for the life cycle of petrol-fuelled passenger cars, the largest share of the respiratory inorganics indicator is attributable to the car production and petrol production.
