Fluid flow through porous material is relevant in different fields of engineering, such as in engine and vehicle development, and can be supported through CFD simulation. Numerical simulations at the pore-scale can be used to replace or reduce expensive laboratory measurements. These methods offer a valuable opportunity to connect the pore-scale properties of the porous material with displacement processes on the continuum-scale. Furthermore, they allow researchers to specify crucial flow properties, e.g., capillary pressure, which are crucial for REV-scale research. Three main methods, direct numerical, pore network modeling, and hybrid approaches, are widely used in order to analyze the pore-scale mechanics of fluid flow behavior through porous materials with CFD simulations. The present comprehensive review demonstrates and highlights the significant advantages, disadvantages, and critical challenges in the pore-scale fluid flow simulations. The main challenges include the characterization of material properties, and up-scaling process from pore to continuum or field-scale.

This study examines the differences in travel behavior between regular and occasional demand-responsive transport users (public transport users), determines the level of service satisfaction, and identifies the key factors of commuters' preferences of using the demand-responsive transport regularly or occasionally for a small-sized urban area (<50 km2). Data were supplemented through field surveys and by focus group discussions. Binary logistic regression and correlation models were used. It is found that probabilities of irregularity are higher for rural areas, male commuters, short trips, educational trips, low-income groups, and non-direct trips. All users are generally satisfied with the service. The most important factors for occasional users are waiting time, trip cost, and trip duration. On the other hand, regular users pay more attention to cleanliness, safety, and comfort. Scheduling of public transportation lines that serve educational zones and provide accessibility to rural areas are needed to improve the quality and attractiveness of the services.

The main task of the article is to define the critical minimum number of tests for the dynamics of a traffic node in autonomous driving based on critical phenomena, i.e. the percolation theory. The critical (minimum) number of tests of a node means how we can represent the traffic dynamics of a node with critical, percolating path using a "state-following state" system on the graph. The test cases along the percolation path, i.e., those involved in the formation of the new phase, represent the entire test system and are minimal. In the article we show that only less than 10 of the 640 tests to be performed have to be realized and are representative for release processes.

This paper analyzes damage to safety systems over a five-year period for a group of vehicles. In the first step of analysis, descriptive statistics characterizing the analyzed variables were calculated and analyses related to the assessment of damage to the braking system. The analyses were carried out in order to examine the relationship between the mileage of vehicles and the number of defects quarterly and monthly and the fit of the obtained empirical results of the analysed variables to a normal or other theoretical distribution was checked. In order to check whether the observed differences in the mean values of the number of failures of the safety systems are statistically significant, a non-parametric analysis of variance was performed. The Kolmogorov-Smirnov test was applied, the distribution of the monthly sum of the braking system faults, distribution of the sum of the braking system faults from individual quarters, distribution of the monthly kilometrage of all vehicles and distribution of the quarterly kilometrage of all vehicles were presented. After describing previous correlation analyses, a linear regression analysis was conducted in which a model was built to predict the number of braking system faults based on monthly vehicle mileage and month of measurement. The last part of the analysis was to verify whether the number of the braking systems faults depends on the season of the year and it was checked whether the season makes any difference to the vehicle's quarterly kilometrage. One-way analysis of variance (ANOVA) was carried out to this end.

The use of modern materials and technical fluids allows you to operate cars at negative temperatures, but in some regions of the world (for example, in Siberia), the ambient air temperature can fall below 243 K for several weeks or even months. The operation of trucks at such a temperature refers to extreme conditions that force the special preparation of equipment. This preparation consists not only of special maintenance, but also of carrying out some activities that are carried out immediately before starting the engine and driving. The essence of these measures is, among other things, the thermal preparation of the components and assemblies of the vehicle before departure.This work is devoted to the thermal preparation of truck shock absorbers. It is revealed that the use of oils, the kinematic viscosity of which significantly depends on the ambient temperature, is a limiting factor in the winter operation of shock absorbers. The simulation of the operation of electric flexible heaters for shock absorbers in the SolidWorks Flow Simulation environment was carried out and the preheating efficiency was evaluated. It is established that the temperature distribution of the shock absorber fluid during heating of two-pipe shock absorbers occurs unevenly, but despite this, preheating significantly improves the characteristics of shock absorbers and contributes to the safe and long-lasting operation of trucks.

A new approach to create the model of individual behavior in urban public transit systems with headway-based service that is built on the same principles of rational decision making as discrete choice models is presented. To describe a passenger's decision-making, the attractiveness function which reflects the difference between trip results and costs was used. The attractiveness of the transit route was determined by solving the system of Fredholm's integral equations based on observed frequencies of choosing the alternative routes by each individual. The frequencies were determined based on multi-day survey results and range between 0 and 1 but equal neither 0 nor 1. To estimate the significance level of the attractiveness function, the regression analysis was used and the accuracy of the choice probability forecast was evaluated. Computation of model coefficients was carried out based on the parameters of home-based work trips obtained via the travel survey that was conducted in the city of Kharkiv, Ukraine.

Road-induced vibrations are in the scope of various environmental testing protocols, e.g., for packaging vibration testing (PVT) purposes. This field matures with well-understood methods for analyzing amplitude-type non-stationarity (NS) in road vehicle vibrations (RVV). Albeit frequency-type NS is well known, only suggestions are provided for processing the phenomenon in PVT. Both types of NS can be jointly investigated in the time-frequency domain; thus, the current study initiates the investigation of spectral non-stationarities (SNS) in RVV. Three vibration series were recorded from 118 km traveled distance supplying an empirical insight.

Highly Automated Vehicles (HAVs) will be more comfortable for their occupants than common cars from different aspects. For instance, their occupants can access extra spaces to adjust their seats as there will be no steering wheel and gearbox transmission handle in the interior. Among a wide range of seating configuration possibilities, the majority of passengers prefer to be in the Face-to-Face or the Living room configurations that are known as non-standard seating configurations. The present survey investigated how safe are these non-standard seating configurations in a side crash in comparison with the standard one in which all seats are facing the front windshield. Four identical 50th percentile Virthuman models were integrated into a schematic of automated vehicle's interior. Standard three-point seatbelts fastened bodies to up-right seats made from Polyurethane foam. A 30 km/h crash acceleration pulse was applied to the model for simulating side crash with a virtual sledge test in the Virtual Performance Solution (VPS) environment, PAMCRASH module. Results revealed that the Living room configuration was safer for the Rear Left occupant in comparison with the Standard one. Also, the Front Left occupant did not experience safer occasions in non-standard configurations from a Head & Neck injury point of view.

Vehicular Ad hoc Network (VANET) is the cutting edge technology for smart transportation. VANET becomes an important aspect of the Intelligent Transport System (ITS). Different safety and non-safety applications have been developed for VANET. The inspiration behind VANET is to provide safe, and pleasant journeys to the drivers and passengers. Although the quality of software depends upon its architecture, most of them do not give proper attention to the consideration of Software-Oriented Architecture (SOA) for providing safety and non-safety ITS services in VANET. To address this issue, we proposed an efficient software architecture by highlighting the important operations and services of the system. The performance of the proposed architecture is evaluated by several design metrics and the results are compared with a state-of-the-art solution. The results showed that our proposed architecture has low coupling and high cohesion factors. Furthermore, the results reveal that our architecture is less complex and more reusable. From the results, we conclude that the proposed architecture is suitable for providing safety and non-safety ITS services and will pave the way for the implementation of the futuristic vision of the ITS.

Many workers face challenges in suburban areas when commuting to the urban areas from home to work. Public transportation is a fundamental component of efficient transportation in urban areas. Efficient transportation will increase economic opportunity, accessibility, and social development. This paper explored the characteristics of commuting behavior of the workers in the Klang Valley who commute to work in Kuala Lumpur, including their choice of transportation modes and the challenges they faced in traveling from home to work. This study engaged a mixed methodology where data were collected from 709 respondents voluntarily. The survey was initiated in December 2020 and lasted for six months. The respondents were approached through voluntary face-to-face and electronic means. Interviews were conducted with 14 key informants in April 2021 with workers from various backgrounds who commute to work every day. The interviews were done one-on-one. The result showed that the likelihood of choosing public transport over driving privately owned car was unfavorable where most individuals stated that the public transportation was insufficient; they had to take more than one modes to reach their workplace, and the facilities provided were insufficient for them to choose public transportation for commuting to work. These results shown that the urban workers in Kuala Lumpur preferred to drive to work rather than using public vehicles. This shows that Malaysians, especially in urban areas such as Kuala Lumpur, are not ready to adapt to SDG 11. Therefore, the government needs to create more initiatives to encourage the use of public transport.
