Assessing Urban Mobility Resilience: An Exploratory Approach Using Hazard-Based Duration Models

Urban systems are vulnerable to disturbances from both natural and human origins, which can disrupt their normal functioning. Evaluating the resilience of these systems, particularly the main transportation networks and their usage levels, is crucial and innovative for understanding the impacts of such disturbances. Thus, this work aims to assess resilience in urban mobility through the probability of a particular journey using a specific mode: “surviving” through critical travel time. To achieve this, a methodology was developed based on the Weibull model with gamma heterogeneity (hazard-based duration models), which was applied to a medium-sized Portuguese municipality. Eighteen groups representing active populations were set and compared. The results indicated that using the bus and cycling are the most resilient modes of transport, whereas walking is the least resilient. Additionally, a specific group was identified as having lower mobility resilience, making them more vulnerable to disruptions in the transport system. Finally, the findings of this study demonstrate the practical application of this methodology, which relies on travel time to assess resilience and, thus, guide political attention and actions to the less resilient mode. Future research should aim to develop a comprehensive framework that incorporates several variables to fully describe the complex nature of transport systems and their resilience.

Analisa Karakteristik Kecelakaan Lalulintas Berbasis Gender di Kabupaten Magetan

Magetan Regency is one of the most remote districts in East Java Province, with a population that increases every year. This causes an increase in transportation needs. The dominant mode of transportation used in Magetan Regency is motorbikes, with the number of motorbikes in 2020 amounting to 317,085 (BPS Magetan Regency, 2023). The increase in the amount of transportation is accompanied by the risk of the transportation itself, namely traffic accidents. The number of traffic accidents in Magetan Regency in 2017 was 547 incidents; in 2018 it increased to 870 incidents. Based on previous research in the Magetan Regency area and its surroundings, it was found that accidents were influenced by human factors. Because of this, this research carried out an analysis of gender-based accident characteristics in Magetan Regency. Based on the results of the analysis using the descriptive analysis method using the cross-tabulation method in IBM SPSS, the driver characteristics were obtained, namely that the age of accident victims was predominantly 17-25 years old, and the majority of drivers had a driving license (SIM). The characteristics of accidents are that accidents are dominated by victims with minor injuries, occur in public places, and on weekdays.

The Influence of Brand Image, Brand Trust, Service Quality through Customer Satisfaction on Honda Brand Motorcycle Brand Loyalty in DKI Jakarta

The automotive industry in Indonesia plays a crucial role in the country's economic development, with motorcycles being one of the most popular modes of transportation. Honda motorcycles have a significant market share among various brands due to their strong brand image, trust, and service quality. This study analyses the influence of brand image, trust, and service quality on Honda brand motorcycle brand loyalty through customer satisfaction in DKI Jakarta. Using a quantitative approach with a survey method, data was collected from 200 respondents who used Honda motorcycles in the DKI Jakarta area. Data was analysed using the Structural Equation Modeling (SEM) technique. The study results show that brand image, trust, and service quality significantly affect customer satisfaction, impacting brand loyalty. Customer satisfaction is essential to strengthening the relationship between independent variables and brand loyalty. These findings underscore the importance of improving service quality, strengthening the image, and building trust to create loyal customers for the Honda brand.

Impact of Areal Factors on Students’ Travel Mode Choices: A Bayesian Spatial Analysis

A preliminary analysis of the 2018/2019 Austin Travel Survey indicated that most off-campus students in Travis County, TX, tend to use cars rather than more sustainable transportation modes, significantly contributing to traffic congestion and environmental impact. This study aims to analyze the impacts of areal factors, including environmental and transportation factors, on students’ choices of travel mode in order to promote more sustainable transport behaviors. Additionally, we investigate the presence of spatial correlation and unobserved heterogeneity in travel data and their effects on students’ travel mode choices. We have proposed two Bayesian models—a basic model and a spatial model—with structured and unstructured random-effect terms to perform the analysis. The results indicate that the inclusion of spatial random effects considerably improves model performance, suggesting that students’ choices of mode are likely influenced by areal factors often ‘unobserved’ in many individual travel mode choice surveys. Furthermore, we found that the average slope, sidewalk density, and bus-stop density significantly affect students’ travel mode choices. These findings provide insights into promoting sustainable transport systems by addressing environmental and infrastructural factors in an effort to reduce car dependency among students, thereby supporting sustainable urban development.

Assessing the environmental benefits of passenger cars electrification in metropolises: A case study of Singapore

Land-based transportation is a significant contributor to global greenhouse gas (GHG) emissions, with internal combustion engine vehicles being the predominant mode of transport in this sector. As the world population grows and urbanization accelerates, transport demand in metropolitan areas is projected to double by 2050, underscoring the critical need for sustainable transportation strategies, forecasting, and planning within an urban context. One challenge in this endeavor is the insufficient attention given to the distribution of vehicle grades within the overall car population during GHG impact assessment, despite the recognized importance of car grade by researchers and policymakers. In this study, we incorporate both engine type and vehicle grade distribution, derived from data on over 30,000 passenger cars registered with the Land Transport Authority of Singapore between 2018 and 2022, into our life cycle assessment analysis. This approach ensures that our scenario-based studies on prediction and planning are more comprehensive than those that consider only the most popular models. Furthermore, while Singapore benefits from a relatively clean electricity supply, the current limitations in charging infrastructure negatively affect the GHG impact of electric vehicles. The insights from this research will inform the development of transportation policies for metropolises like Singapore, contributing to the advancement of a more sustainable transportation system.

Stawanie się miejskim rowerzystą. Biografie mobilności dojeżdżających do pracy rowerem

This article presents the results of semi-structured interviews with eight individuals whose primary or significant mode of transportation in the city is the bicycle. The purpose of the analysis was to describe the trajectory of becoming an urban cyclist. During the interview, three stages of bicycle use emerged: childhood, high school, and college and work. These stages were somewhat more clearly separated by interviewees, who were also able to distinguish periods of cycling and noncycling. At the same time, the beginning of a new stage may represent one of the key moments when survey participants may give up cycling (especially the start of high school) or take up the activity anew (e.g., children entering a period of greater independence). In addition, the start of cycling for transportation purposes may be easier to think about for those accustomed to physical activity, and especially for those cycling for recreational or sporting purposes. The city’s bike-sharing system can be a significant factor in initiating the practice of cycling for people who did not own bicycles and/or have not used them for many years.

Eco-Sustainability in Hospital Pharmacy: A Pilot Survey on 'Going Green'.

Purpose: Between 2009 and 2015, the Canadian health care system was estimated to be responsible for 4.6% of national carbon emissions. Determine awareness of and describe eco-initiatives that the department of pharmacy can implement to aim to reduce the carbon footprint in hospital pharmacy in an effort to 'go green'. Methods: In a quality improvement initiative, pharmacy employees (i.e. pharmacists and pharmacy technicians) completed a cross-sectional survey designed to gauge willingness to 'go green' at work, to identify actionable areas of waste, and to assess commuting practices. Results: A total of 15 respondents completed the survey conducted March 14th -April 7th, 2022. Most respondents (73%) were willing to engage in more sustainable practices at work. The main barriers to implementing green practices at work were 'too time consuming' (20%), 'adds too much complexity' (20%), and 'cost' (16%). For commuting, 60% indicated the primary mode of transportation as 'personal vehicle', where 'subsidized transit' and was listed as the greatest incentive that could encourage a greener commute. The three largest areas of waste cited were 'single use plastic' (36%), 'limited of awareness of green practices' (15%), and 'lights left on in empty rooms' (12%). Conclusions: Pharmacy staff shared willingness to engage in more sustainable 'go green' practices but raised challenges to do so. With the knowledge that Canada has the second most climate intensive health system, there is a need for future research to describe how hospital pharmacies can contribute strategically to 'go green', advancing with implementing low carbon sustainable pharmacy practices.

Design for shared driverless vehicles of the future

On-demand shared transportation is a major new mobility innovation and potentially the main mode of transport in coming decades. Studies show that driverless vehicles have potential to accelerate uptake of shared vehicles at scale. People perceive sharing positively but do not necessarily translate perception into action, with desire for personal space a major reason for unwillingness to share vehicles. Design research is a powerful tool when creating methods and processes to anticipate future possibilities by visualising detailed features of proposed products. We present a set of design research methods engaging end users in a variety of empathy activities and a design process to translate their needs into visual concepts for future shared driverless vehicles that are attractive and more likely to be adopted.

Physical Origin of the Ferroelectric-Type Hysteresis in MIM Structures with Amorphous Dielectric Film.

The ferroelectric-type characteristics in metal-insulator-metal (MIM) structures with amorphous dielectrics are observed, which may open a new window for a class of new ferroelectric devices. However, the working principles of these ferroelectric devices are not well explained. It has been proposed that oxygen ion (O2-) and charged vacancy (Vo2+) migrations are associated with this ferroelectric-like behavior. In this work, a systematic experimental design is carried out to investigate the origin of O2- and Vo2+ (from the interface or bulk oxide?), the transport species (O2-, Vo2+, or both of these two species?), and the ion transport mode (long-range transport or local movement?). The experimental results answered all these questions. In addition, the role of the thickness of the dielectrics is also studied. This work sets the fundamentals of these amorphous oxide-based devices, guiding future explorations to engineer them.

How workable is a 20-minute city in Australia? Re-examining the challenge of change in spatial labour and job relations

ABSTRACT Most x-minute city studies focus on liveability and neighborhood accessibility to local services, but rarely include primary employment. This paper complements these studies by examining the urban employment structure and transport dynamics of an Australian city under the 20-minute city concept framework. To do this, we develop a comprehensive method to model residents’ job access time using census-based journey to work (JTW) data and detailed household activity and travel survey. Analysing JTW time stepping down to diverse industry and employment categories and transport modes allows new insight into the disparity in residents’ job and housing locations and transport choices at local scales. By evaluating the distribution of working residents, types of employment, and transport performance, this paper examines possible policy responses and challenges of change in expanding the 20-minute planning target for employment. The analysis suggests that housing infill development could support reduced JTW time for residents experiencing longer time for work travels. However, this would require active planning of both land-use mix and dwelling design to meet prevalent household expectations about dwelling size and quality.

GHRH-stimulated pituitary small extracellular vesicles inhibit hepatocyte proliferation and IGF-1 expression by its cargo miR-375-3p

Small extracellular vesicles (sEV) have emerged as a novel mode of intercellular material transport and information transmission. It has been suggested hormones may regulate the production and function of sEV. However, the specific impact of growth hormone-releasing hormone (GHRH) on pituitary sEV production and the role of sEV in the regulation of the GHRH-GH-IGF axis has not been previously reported. The results of the present study demonstrated that GHRH increased the production of pituitary sEV by promoting the expression of Rab27a. More importantly, GHRH induced alterations in protein and miRNA levels within GH3-sEV components. Notably, GH3-sEV with GHRH treatment exhibited the enhanced ability to impede BRL 3A cell proliferation and the expression of IGF-1. Conclusively, for the first time, we corroborate the influence of GHRH on pituitary sEV, thereby presenting novel evidence for how sEV participates in the balance of the GHRH-GH-IGF axis. Importantly, this study provides new insight into a novel balance mechanism mediated by sEV within the endocrine system.Graphical

The role of physical and social environments on the loyalty toward urban rail services: A consideration of stations and onboard

Although urban train services have been introduced in various developing countries, ridership for this mode of public transport (PT) remains low. In response, urban planning authorities are seeking ways to boost passenger loyalty to these services. However, the existing literature has scarcely examined the role of physical and social environments in fostering passenger loyalty. Additionally, how loyalty is developed throughout the passenger experience - both at stations and onboard - remains unclear. Addressing this gap, the current study develops a model based on the 'service quality-satisfaction-behavioural intentions' paradigm and the Stimulus-Organism-Response (S-O-R) model to examine how the physical and social environments, both at rail stations and onboard trains, impact passenger loyalty in the context of urban train services. Additionally, this study validates the multi-dimensionality of physical environments and social environments in this context. Data collected from urban rail passengers in Hanoi, Vietnam is analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The findings reveal that the physical and social environments onboard trains significantly influence loyalty towards the urban train services, while the environments at stations do not have the same impact. Furthermore, both satisfaction at stations and onboard trains significantly affect the loyalty, though the influence of satisfaction with the onboard experience is much stronger than that of satisfaction with the stations. Practically, the findings assist PT authorities in evaluating existing systems and devising future PT development strategies. Also, the study informs PT providers of ways to improve passenger satisfaction and loyalty.

The Impact of Innovative Transportation Services on Travel Behaviors: A Case Study of Istanbul

There has been a paradigm shift in urban mobility around the developments in information and communication technologies, zero emission targets to reduce transport-related emissions. Hence, traditional transportation services are replaced by sustainable, shared, smart, innovative mobility services. It is crucial to understand what extent these services, which are increasingly used in the cities and have potential to become a part of the main transportation system of the city rather than serving as an alternative mode of transportation, affect people's travel behaviors and daily activity preferences to be aware of the trends in urban mobility, passenger and freight mobility. By this study, new mobility services such as micromobility, car and ride sharing services used in Istanbul examined in the context of (1) their effect on travel behavior (2) the relationship between people's demographic, socioeconomic status and new transportation service use (3) the conditions where the adoption of these services are higher. In this study, survey was conducted with a sample of 404 people in Istanbul and the results were interpreted using both explanatory analysis methods and the chi-square independence test as a statistical method. As a result of the study, questions such as what is the relationship between the demographics, travel behaviors and the use of new mobility services, the effect of these services on the total trips, transportation modes replaced by them, in which situations they are preferred or not and under what conditions those who do not use this service can use them were answered

An extended substrate spectrum of the proton organic cation antiporter and relation to other cation transporters.

Most central nervous system (CNS) active drugs are organic cations, which need carrier proteins for efficient transfer through the blood-brain barrier (BBB). A genetically still unidentified proton organic cation (H+/OC) antiporter is found in several tissues, including endothelial cells of the BBB. We characterized the substrate spectrum of the H+/OC antiporter and the overlap in substrate spectrum with OCTN1, OCTN2 or OCT3 by screening 87 potential substrates for transport activity. Based on high antiport rates, 45 of the tested substances were substrates of the H+/OC antiporter. They included antidepressants (like tranylcypromine or nortriptyline), antipsychotics (like levomepromazine) and local anaesthetics. Concentration-dependent transport was confirmed for 38 of the substrates. Transport uptake depending on a pH gradient across the cell membrane confirmed that 43 drugs were indeed substrates of the H+/OC antiporter. However, the patterns of pH dependence differed between the substrates, possibly indicating different modes of transport or the existence of multiple antiporter proteins. The substrate overlap between the H+/OC antiporter and OCTN1, OCTN2 or OCT3 was minimal, indicating that the latter three are not the proteins underlying the H+/OC antiporter activity. Overall, about 50% of positively charged drugs may be substrates of the antiporter, which may be the most important membrane transport protein for many drugs.

Spatio-temporal dynamics and recovery of commuting activities via bike-sharing around COVID-19: A case study of New York

The COVID-19 has led to significant changes in urban travel behaviors, with commuting being one of the most affected travel modes. Commuting cycling by bike-sharing systems (BSS) is regarded as a new transportation mode that is low-carbon and low-cost. However, its dynamic changes and spatiotemporal characteristics in different periods of COVID-19 still lack exploration. Therefore, this study adopts machine learning methods to identify commuter bike-sharing activities and develops a combined analysis method to analyze commuting cycling data via temporal, spatial, and spatiotemporal aggregation. Finally, we select the bike-sharing data in New York City from periods before, during, and after COVID-19 to conduct experiments. It has been found that commuting cycling experienced a “decrease-rebound” trend at the macroscopic level under the pandemic impact. However, at the micro level, urban mobility driven by this travel mode failed to fully recover, as evidenced by significant changes in spatial and temporal mobility patterns. The findings shall not only help traffic operators and managers discover the BSS commuting patterns but also reveal the pandemic impact on the travel behavior of urban residents, promoting the development of intelligent services for urban emergency management and traffic management.

A Literature Survey On Signalized And Non-Signalized Corridors

Random traffic flows and the influence of traffic signals at intersections often cause significant variations in travel times. This has implications for signal control planning and design. This study aims to compare the variability between signalized and unsignalized corridors in Lahore and identify the challenges faced by road users. The study was conducted through a literature survey that collected data on trip purpose, frequency, travel time, and transportation mode choice from various sources. Results show that signalized corridors have lower accident rates and shorter travel times compared to unsignalized corridors. Unsignaled corridors, on the other hand, offer better access and lower fuel costs. Although signalized corridors are more effective in managing traffic flow and improving safety, further research is needed to explore alternative solutions such as roundabouts that can improve mobility and sustainability. The results of this study can serve as a reference for transportation planners and policy makers in designing a more efficient traffic system. This study also suggests the need for further evaluation of traffic control in various urban contexts to optimize safety and efficiency.

An overview of maglev trains

This paper provides a detailed review of maglev (magnetic levitation) trains, explaining the technology and underlying principles behind it. It also covers the history of this evolving mode of transport. Moreover, it addresses and analyzes the advantages and challenges of maglev trains compared to the traditional rail system: technical, infrastructural, and economic factors have been taken into consideration. Further, it explores the potential improvements to the technology to make it more efficient and cost-effective. The paper will focus slightly more on the Japanese maglev trains as they are the most developed. This paper aims to become a one-place resource for readers to gain knowledge about maglev trains. The author was motivated by the fact that this field, despite being so heavily researched, has a lack of research papers or articles published for readers and inquirers to easily learn about the whole concept; the majority of papers found were published in the early 2000s. Therefore, this paper also intends to include the latest advancements. It is an overview, written after going through multiple past research papers, websites, informative videos and videos of interviews from reliable and credible sources.
