The Impacts of Mobility-as-a-Service (MaaS) on a Diverse Society: A Framework for Advanced Assessment

With the latest developments in transportation technologies and services, the concept of MaaS has spawned its way, where consumers can purchase access to different modes and services owned and operated by several mobility service providers through a single integrated digital platform. Nonetheless, the MaaS ecosystem and benefits have not been fully understood yet, which varies case by case depending on the communities' behavioral responses. Qatar is known as one of the countries with a highly diverse population where many expatriate workers come from different cultures. This necessitates a comprehensive mobility arrangement given their various travel needs and diaries. To contribute to a comprehensive analysis of MaaS impact while taking into consideration societies' diversities, this paper aims to develop a framework to assist in evaluating and assessing MaaS design alternatives and their impact on different population segments. This study was conducted by utilizing existing literature findings about MaaS assessment supported by a stated preference (SP) survey from a Qatar case study. We found that there are a limited number of key performance indicators (KPIs) to comprehensively evaluate MaaS social impacts and mobility network efficiency. Therefore, as part of the assessment framework, additional KPIs were introduced for comprehensively evaluating MaaS's direct impact on transport networks and broader implications for social equity, economy, and human well-being. MaaS KPIs should consider reporting by age, monthly income, and ethnic socio-demographic factors. This can serve as a useful guide for diverse communities, particularly in Qatar. Furthermore, outputs from the assessment framework can be used as inputs to evaluate impacts on the MaaS provider's profit-making and business prospects.

How does smart transportation technology promote green total factor productivity? The case of China

Understanding the role of smart transportation technology in driving China along an efficient development path is crucial; nonetheless, scholars have paid little attention to the pathways toward green total factor productivity through smart transportation technology. Hence, this study aims to assess the level of smart transportation technology, and then investigate its impact on green total factor productivity using the instrumental variable-generalized method of moments (IV-GMM) model. Our main findings are as follows: (1) The primary finding provides solid evidence of the positive impact of smart transportation technology on green total factor productivity, which means smart transportation technology effectively and efficiently accelerates the green development process. (2) The asymmetric nexus between smart transportation technology and green total factor productivity indicates that smart transportation technology plays a more powerful role in areas with lower levels of green total factor productivity despite the fact that a positive relationship exists across all quantiles. (3) The increasing green total factor productivity effect caused by smart transportation technology development is realized through enhanced energy consumption efficiency and industrial structure transition. We propose some suggestions for improving green total factor productivity from the perspective of better smart transportation technology research and application.

Design of Audio-Based Accident and Crime Detection and Its Optimization

The development of transportation technology is increasing every day; it impacts the number of transportation and their users. The increase positively impacts the economy's growth but also has a negative impact, such as accidents and crime on the highway. In 2018, the number of accidents in Indonesia reached 109,215 cases, with a death rate of 29,472 people, which was mostly caused by the late treatment of the casualties. On the other hand, in the same year, there were 8,423 mugs, and 90,757 snitches cases in Indonesia, with only 23.99% of cases reported. This low reporting rate is mostly caused by the lack of awareness and knowledge about where to report. Therefore, a quick response surveillance system is needed. In this study, an audio-based accident and crime detection system was built using a neural network. To improve the system's robustness, we enhance our dataset by mixing it with certain noises which likely to occur on the road. The system was tested with several parameters of segment duration, bandpass filter cut-off frequency, feature extraction, architecture, and threshold values to obtain optimal accuracy and performance. Based on the test, the best accuracy was obtained by convolutional neural network architecture using 200ms segment duration, 0.5 overlap ratio, 100Hz and 12000Hz as bandpass cut-off frequency, and a threshold value of 0.9. By using mentioned parameters, our system gives 93.337% accuracy. In the future, we hope to implement this system in a real environment.

FEATURES OF THE REGIONAL MARKET CARGO TRANSPORTATION MARKET DEVELOPMENT IN KHERSON REGION

Objective. The purpose of the study is to identify the specifics of the development of the regional freight transportation market in the Kherson region, taking into account advanced transportation technologies and assessing the concentration of the freight transportation market. Design/methodology/approach. The following research methods were used: problem-oriented (in terms of identifying the problems of the freight transportation market and factors influencing it); logical generalization, analysis and synthesis (to formulate conclusions about the prospects for the development of the multimodal freight transportation market in the region); structural and factual analysis (to analyze the structure and dynamics of freight transportation parameters); index method (to determine the concentration of the regional multimodal freight transportation market using indices). Conclusions. The analysis of the elemental structure of the logistics system of the Kherson region with the participation of water transport showed a developed infrastructure of cargo transportation and ample opportunities for focusing participants around the centers of the transportation process. The asymmetry of price competition for access to port berths and roadside transshipment was revealed, which distorts equal working conditions for cargo transportation market participants and modifies the structure of cargo transshipment and, accordingly, the centers of dominance in the target markets of multimodal transportation. Prioritizing the export of bulk cargo and import of containerized cargo in the Kherson region requires the development of a transport policy that would ensure the freight independence of cargo flows, and the identified unstable dynamics of the geography of transportation routes in the region requires the expansion of alternatives for choosing parameters and directions for the development of transportation technologies for servicing local cargo flows. It is also necessary to balance the existing advanced development of the grain cargo delivery infrastructure against the capacity of their one-time storage in grain terminals in ports. It has been established that the multimodal transportation market of the Kherson region (as of 2021) is characterized by an uneven distribution of market shares between transport enterprises, is highly concentrated, with a low level of competition and the threat of monopolization. Market power in the “market core” is evenly distributed among PJSC “Ukrzaliznytsia”, SE “Kherson Commercial Sea Port”, and LLC JV “Nibulon”. The Herfindahl – Hirschman index confirmed the concentration of power among these three enterprises, identified by the concentration index, which amounted to 80.87 %. The lower share of the transport sector of the Kherson region in the total economic activity of cranes in the period 2015–2020 in favor of other industries was identified, and therefore the insufficient level of meeting the production and non-production needs of consumers in the region in all types of cargo transportation. Practical implications. The results of this study are of interest to multimodal transportation market operators and cargo owners who are interested in actively implementing the logistics concept in regional development and building multimodal regional clusters. In this way, it is expected to increase the attraction of cargo flows to the regions, the development of competition; employment growth in the freight transportation sector and other related industries. The results of the assessment of the development of multimodal freight transportation can be taken into account by the Logistics Coordination Council under the Ministry of Infrastructure of Ukraine when forming the strategic framework for the development of the country‟s logistics system. Originality/value. Assessment of the concentration of regional markets will provide an analytical basis in the process of forming a mechanism for ensuring the integrated efficiency of multimodal transportation of goods and minimizing interregional asymmetries: in terms of levels of cargo flows in accordance with the stated needs of consumers; the state of transport and logistics infrastructure; availability of all types of vehicles, service levels, etc.

Axial Unipolar Eddy Current Brake Performance Characteristics Against Heat Increase in Rotor

The development of transportation technology in the automotive sector such as electric vehicles is increasingly advanced. One technology that is needed quite a lot is the development of supporting technology for electric vehicle braking. The use of regenerative braking on light electric vehicles such as 2-wheeled vehicles is not efficient because of its low weight. The use of Eddy Current Brake (ECB) can be a solution for braking support needs. This is because the ECB is a braking system that has the advantage of a lightweight design but still relies on the frictionless principle. However, in addition to its advantages, the eddy current brake is still in the early stages of its research with efficiency that still needs to be developed. In the discussion of the ECB, heat generation is one of the interesting topics to be discussed. Specifically, the study of the characteristics of the unipolar ECB axial performance on heat generation events has not yet been discussed. So this article aims to discuss these events with a simulation process and simple mathematical calculations. Design optimization is done to get the best value. As a result, the use of eddy current brakes with conductor disks using slots, can improve the performance of the ECB on the torque side and cooling side. Thus, this article is a good contribution to the sustainability of ECB research in both the general and automotive fields.

TENG Applications in Transportation and Surrounding Emergency Management

AbstractWith the rapid development of transportation technology, people's lives are becoming more and more convenient, but the popularity of high speed transportation also increases the probability of emergencies. Therefore, it is necessary to conduct real‐time and accurate monitoring on transportation conditions to reduce the occurrence of emergencies. For possibly emergencies in other circumstances (e.g., meteorological disasters, geological disasters, and maritime disasters), emergency management is also critical to ensure the security of people and property. Prediction and early‐warning can help to detect abnormal situations and take measures, prior to potential risks. The basis of real‐time and effective transportation monitoring and emergency management requires a continuous and stable power supply for randomly distributed sensors and actuators. Triboelectric nanogenerators (TENGs) have been extensively investigated in different transportation circumstances to harvest the surrounding energy and drive distributed sensors for self‐powered wireless monitoring. This article surveys the research progress in TENGs in road transportation, bridge transportation, railway transportation, and maritime transportation, and related surrounding emergency management. Representative applications and the main achievements are summarized for these different application scenarios. A perspective on TENG research is given, and the remaining challenges facing TENGs in transportation and emergency management are discussed, along with potential solutions.

Visualization and Analysis of Transport Accessibility Changes Based on Time Cartograms

Visualization of the spatial distribution pattern of transport accessibility and its changes can be crucial for understanding and assessing the performance of transportation systems. Compared to traditional maps representing geographic space, time cartograms modify geographic locations and spatial relationships to suit travelling times and thereby emphasize time–distance relationships in time-space. This study aims to facilitate a better understanding of the evolution of the spatial distribution pattern of accessibility by presenting a novel visualization and analysis methodology based on time cartograms. This is achieved by combining a visual qualitative display with a quantitative indicator analysis from multiple perspectives to show transport accessibility changes. Two indicators, namely, the shortest railway travel time (STRT) and spatiotemporal con-version parameter (STCP), are proposed to measure accessibility changes. Our work consists of the construction of time cartograms, the analysis of indicators, and the use of multiple views to show changes in transportation accessibility from multiple perspectives. The methodology is applied on the railway data of Beijing and selected 226 cities in China and to analyze changes in railway accessibility in 1996, 2003, 2009 and 2016. The results show that the development of transportation technology has continuously shortened the travel time, the time-space is gradually compressed, However, the difference in transport accessibility is getting bigger and bigger because of the uneven transportation development speeds between the regions.

Maritime Security Governance: A New Strategy Management To Avoid Piracy In The Gog And Its Legal Guarantee

In the late 21st century, the growth of sea ships widened the horizons for trade on a global level. However, despite slow and cumulatively significant developments in transportation technology, during the era of sail, high sea maritime instability or the threats of piracy remained a significant obstacle to trade over long distances. In addition, with limited solidarity among all essential players in the region, several Gulf of Guinea (GoG) states can diversify their national attention to handle the pandemic instead of combating illegal activities at sea. Therefore, this article talks about the different factors of maritime piracy in the GoG, Comparing the trend across the region's different states (Togo, Benin, Nigeria, Ghana), the current maritime insecurity mitigation strategies proposed, and their gaps. Besides, a discussion around a knowledge gap in terms of accurate cooperation via the various policies implemented by those institutions brings us to propose coevolution governance in the shadow of the hierarchy and to create a maritime protect area (MPA) in the GoG country who do not have it yet, especially in Togo, Ghana, and Nigeria, and surround MPA with sustainably managed fishing areas where local small-scale fishers enjoy exclusive rights. The result shows that regionally it can help Centralize and diffuse the best practices, develop greater synergy among public policies and institutions, and nationally create greater sustainability of conservation with the integration of socio-economic concern and harmonization of strategic planning, practices, and policies.
