Urban Mobility Modeling in PTV Visum with Various Options for Bus Fare Structure

The study focused on applying linear and non-additive fare structure models to simulate flat fares with a set of constraints for each fare model that can be used on public transport in real-world conditions. To this end, a method for modeling flat fares using PTV Visum software, specifically the origin-destination fare model, has been developed. The impedance function, which is used in the public transport headway-based assignment, is determined to minimize deviations between actual and calculated passenger volumes for bus routes using SQV statistics. The case study aims to develop a method for modeling flat fares within PTV Visum to predict and analyze passenger traffic on municipal bus routes in the Ukrainian city of Kryvyi Rih in the case of implementing flat fares for these routes. Two options were modeled: the current situation with a flat fare of UAH 15 (EUR 0.35) for bus routes run by private operators and fare-free public transit for municipal bus routes, and an anticipated scenario with a flat fare of UAH 15 (EUR 0.35) for bus routes operated by private companies and a flat fare of 8 UAH (0.18 EUR) for municipal bus routes. These evaluations provide insight into passenger flows on municipal bus routes under the existing fare option and in the case of implementing a charge for municipal transport in Kryvyi Rih. Obtaining results of passenger volumes and devising an approach to fare modeling is crucial for transportation sector decision-makers, aiding in the development of effective fare strategies within the city

Effect of Coconut Fiber Content on the Properties of Unfired Building Bricks Incorporating Thermal Power Plant Ashes

This study examined the effect of coconut fiber (CF) content on the properties of unfired building bricks (UBBs) using fly ash (FA) and bottom ash (BA) from the Nghi Son coal-fired thermal power plant (CTP). Cement and FA served as binders while BA replaced crushed stone as the fine aggregate. Raw brown CFs were treated with a 5% NaOH solution at 50 °C to increase their mechanical properties. The treated CFs were then cut to a short length of 15 mm and had an average aspect ratio of 103. Brick samples were cast with CF content at ratios of 0%, 3%, 6%, and 9% by binder weight (CF/B) and water-to-binder (W/B) ratios of 0.30 and 0.35. The UBBs were formed under a low pressure of 0.5 MPa and tested to evaluate the effects of CF/B and W/B ratios on brick properties. Results showed that compressive strength (CS) increased with higher CF content, with all samples exceeding 10 MPa after 28 days, classifying them as grade M10 per TCVN 6477:2016. The optimal CF content was 6%, which yielded the highest CS. Increasing CF content reduced unit weight (UW), ultrasonic pulse velocity (UPV), and thermal conductivity (TC), while water absorption (WA) increased. Conversely, a lower W/B ratio improved CS, UW, UPV, and TC, while reducing WA. Microstructural observations revealed that CF acts as a bridge connecting cracks, which helps restrain crack widening and enhance CS

Mechanical Behavior of Layered Composite Structures of Aluminum Foam Partially Filled with Polyamide

In this study, the mechanical properties of layered composite structures were investigated. We achieved the layered structure by hot-pressing 1 mm, 3 mm, or 5 mm thick polyamide 6 (PA) sheets into the pores on the top and bottom sides of an open-cell metal foam at 240 °C and 15 MPa (150 bar). The PA-infiltrated depths varied with the thickness of the hot-pressed PA sheets. According to the bending and post-impact bending tests, flexural strengths improved as the infiltration depth of PA increased. Compared to the metal foam, a maximum of 15% increase in flexural strength and a 400% increase in residual flexural strength were measured. However, using a 1 mm thick PA sheet lowered the flexural strength of the open-cell metal foam. We found that the 1 mm thick PA sheet failed to fully infiltrate the foam pores, resulting in residual voids at the metal-PA interface, which caused premature fracture during bending

Towards Sustainable Transport: An Analysis of Urban Mobility in Hyderabad, Telangana Using Uber Movement Data

Cities worldwide face traffic congestion, challenging sustainable development and requiring insight into its dynamics, dispersion, and stability. Effective traffic management is pivotal for fostering sustainable urban mobility and enhancing quality of life. Leveraging Uber movement data, this study examines travel times and speeds across Hyderabad over a four-year span from 2016 to 2019. Congestion and friction indices from travel time matrices, along with network analysis, gauge urban accessibility, revealing similar magnitudes of Congestion and Travel Time Delay Transition Indices for inbound and outbound traffic within specific intervals. Notably, there is an inverse proportional relationship between these two indices. The Congestion Index values indicate that most zones experience significant traffic jams, while the Travel Time Delay Transition Index was calculated to affirm its inverse relationship with the Congestion Index. Employing fractal geometry, the study delves into the spatial complexity of the network and its correlation with urban growth parameters, contributing to sustainable urban planning efforts. Furthermore, the fractal dimension value obtained from the Mass-Radius method is 1.6955, with a correlation coefficient of 0.99, indicating a high degree of linearity between the road network and friction index. Results underscore the intricate interplay between traffic congestion, macroeconomic factors, and urban form, highlighting the imperative of integrating sustainability principles into transportation policies. By leveraging readily available Uber movement data, this research provides a comprehensive assessment of citywide traffic conditions, offering valuable insights for crafting sustainable transportation management strategies aimed at mitigating congestion and promoting equitable access to mobility

Prediction Model for Track Quality Index Categories on the Northern and Southern Railway Lines of Java

Track quality index (TQI) is a quality metric that objectively measures the geometric condition of railway tracks for maintenance planning. The TQI categories serve as the basis for proposed track maintenance. The TQI measured by the EM120 track recording car on Java island currently covers only 78.84% of the 5,634.363 km of railway tracks, indicating that there are still track sections without TQI category values. This study aims to model the maintenance of railway infrastructure based on TQI categories derived from both track recording car results and manual measurements across various sections of railway lines on the northern and southern routes of Java island. The analysis used is based on the standard deviation of railway track geometry, including superelevation, levelling, lining, and track gauge. Factors such as turnouts, bridges, crossings, straight sections, and curves were then classified as predictive factors. Machine learning techniques were adopted, with 80% of the data set randomly used for training and the remaining for testing to generate TQI category predictions. A total of 233,175 TQI data points from 2019–2022 were used to build and validate the model. The results indicate that the multinomial regression model for TQI Categories 1, 2, 3, and 4 is highly accurate, the rest is influenced by other factors. These results imply that the model has an exceptional fit and excellent predictive capability for TQI on the northern and southern railway lines of Java island

The Comparison of Attributes of Social Intelligence and Machiavellianism in Managerial Work

This paper aims to contribute on a theoretical and empirical level to the solution of questions related to the use of social intelligence and Machiavellianism in the management profession, based on the theoretical treatment of the issue. It sets out to specify mutual differences and relationships relating to selected attributes of methodologies used to determine social intelligence and Machiavellianism in the conditions of managerial work. The research sample consisted of 234 participants (131 women) aged 28 to 40 (mean = 28.72; SD = 6.67). The respondents worked in both the private and public sectors in managerial and non-managerial positions. The data from the respondents were obtained by questionnaire methods, processed and analysed by mathematical-statistical methods at the descriptive and inductive statistical level, as well as more advanced statistical methods. The methods provided data on basic sociodemographic characteristics, social intelligence (MESI questionnaires) and Machiavellianism (VYSEDI). The results of the project contribution brought knowledge at the level of theoretical, empirical, as well as in the practical application of the acquired knowledge. Within the established hypotheses, we found statistically significant differences in selected attributes of social intelligence and Machiavellianism within the managers' workplace setting, as well as differences between managers and non-managers. We also identified mutual correlations between selected attributes in relation to age. On the basis of the presented results, findings and knowledge, as well as the summary and refinement of the results for practical applications, it can be concluded that the goal of the contribution has been fulfilled

An Ontology-based Approach to Solving the Digital Representation Problem in Architectural Engineering

This article addresses the need for computer-aided design systems in Architectural Engineering (AE) design for building construction, an essential aspect of every building's design that is currently underserved by existing software solutions. First, we analyse the various challenges facing the development of better tools and propose that a fundamental problem of representation lies behind most of them. Next, we suggest a desideratum for representing building constructions digitally in our tools, and we argue that a formal ontology is best suited for the task. Numerous systems have been proposed for developing ontologies, many of which rely on a domain-independent upper ontology. This common upper layer supports the creation of more specific ontologies in an interoperable and mutually supportive way. The BFO upper ontology and the corresponding methodology are briefly introduced, followed by a review of many existing ontologies relevant to AE. Lastly, we introduce a prototype proto-ontology for describing building constructions and their related phenomena: the building construction ontology. We present the most important terms and modules of BCON and then demonstrate its use through a small case study of a relatively simple construction detail. Finally, we highlight the many possible applications of such a representational system
