Public transport mode choice behavior of different-income passengers during large-scale public health incidents

Public transport ridership has been hit hard by the COVID-19 pandemic in many countries. Investigating passengers' public transport mode choice behavior during large-scale public health incidents can uncover the major influential factors and help propose policies and strategies to reduce the pandemic transmission and recover the public transport revenue. This study develops an integrated choice and latent variables (ICLV) model by income based on structural equation model to model passengers’ public transport choice behavior during the normalized stage of the pandemic. The model considers passengers’ socioeconomic attributes, travel attributes, and attitude-perception attributes, and can appropriately capture passengers’ psychological latent attributes. Taking Beijing China as an example, we collect some revealed preference survey data online. The modeling results show that the risk perception as a mediator variable has a significant impact on mode preference. Moreover, the convenience of public transport has the largest influence on risk perception. These findings suggest that risk perception and the convenience of public transport play a major role in passengers’ mode choice behavior. In addition, the impacts of the various influential factors on the public transport mode choices are significantly different across different income groups. Further, the ICLV model can achieve better performance and is superior to the traditional Multinomial Logit model. The modeling framework can help propose targeted and instructive strategies during the normalized stage of the pandemic by uncovering the major influential factors in passengers’ public transport mode choices, which is applicable to similar pandemics in the future.

"A Smart Sociopolis" is a sociopolis that has achieved the "smart" status by implementing projects that improve the living conditions for the community as a whole in various sectors through information and communication technologies. Therefore, for a sociopolis to be considered smart, it should be convenient for its residents. When evaluating smart sociopolises, the main areas are ecology, social sphere, innovation and technology, public transportation, economy, and management systems. The transportation sector in smart cities plays a crucial role in ensuring efficient mobility, reducing traffic congestion, and enhancing the quality of life for residents. Common residents (if he or she doesn’t work from home, or don’t live near their work) spend from one to three hours each day to arrive at the office, plant, or another type of workspace and versa, to arrive to the home. Also, the current residents can use their own vehicle or public transport such as busses, subway, trolleybus, etc. One of the important aspects of "convenience" in a smart sociopolis is transport and transportation infrastructure. One of the most important targets of smart sociopolisies in field of the transport infrastructure is to reduce the number of vehicles on the streets, reduce air pollution, and make more popular and convenient public transport, especially by using information and communication technologies, because they can improve in short perspective the infrastructure with fewer costs, involved in the development of the implementing projects. To some extent, the transportation infrastructure, specifically the network of roads, is a strategic component of the development of a smart sociopolis, requiring special, particular, and separate development, an analysis of the current state, and planning for the construction of future pathways. The article highlights the features of creating and implementing information systems aimed at optimizing the transport infrastructure in the city of Truskavets. The authors discuss key aspects of a smart city and approaches to using modern technologies such as the Internet of Things (IoT) and data analysis to improve the quality of life for residents and the efficiency of city management. The research reflects the importance of integrating various sources of information and developing information infrastructure to achieve the goal of creating a smart and efficient sociopolis.

Urban vibrancy and air pollution: avoidance behaviour and the built environment

ABSTRACT Urban vibrancy can be captured by people’s out-of-home mobility. It is an essential indicator of the ‘liveliness’ of cities. Nowadays, many cities, however, are suffering from air pollution, which is harmful to human health. As such, health authorities are advising people, especially vulnerable groups with respiratory or other chronic diseases, to avoid out-of-home activities and travels on polluted days. With such avoidance behaviour, how would urban vibrancy decline in response to air pollution? How does the built environment moderate such declines? Applying spatial econometric approaches on panel data comprising social media check-in records, air quality index, meteorological conditions and built environment characteristics, this paper delves into the relationship between air pollution and urban vibrancy in Guangzhou using fine spatial (1km*1 km grids) and temporal (daily) data over two years from 2018 to 2019. The research findings provide clear evidence that air pollution is negatively associated with urban vibrancy. Furthermore, our study suggests that urban vibrancy of places with higher points of interest intensity and being farther away from the city centre are more affected by air pollution, whereas vibrancy of places with higher public transport convenience, smaller blocks, and higher functional mixture tend to be less vulnerable. The findings provide evidence-based implications for city governments to better understand and capture gains of urban vibrancy from pollution regulations and built environment design for sustainable urban development. The lessons learned are applicable to other cities with emerging air pollution problems.

Assessing the Hierarchical Diversity of Public Transportation Considering Connectivity and Its Implication on Regional Sustainability

Given a decreasing and aging population, there is a growing need to establish convenient public transportation systems that offer a variety of transportation modes seamlessly connected to one another. This study attempts to develop an index to assess the hierarchical diversity of public transportation, drawing an analogy between public transportation networks and ecosystems. By considering both hierarchical (meta-physical) and physical connections among respective modes, which are aspects that have not been addressed in previous studies, this study aims to enhance the spatial resolution of the analysis units in the index. The diversity indices were applied to the northern Osaka area in Japan as the study site. The results show a correlation between the diversity index, population, and public transportation modal share. We then discuss the influence of hierarchical diversity on the sustainability of public transportation systems and regional development.

서울시 지역별 주택가격 결정요인

This study conducted empirical analysis using the hedonic price model to examine regional differences in the determinants of housing prices among the representative examples of decoupling phenomena in inter-regional housing price movements, namely, “Gangnam 3-gu”, “Nodogang”, and “Mayongseong”, from 2017 to 2022.
 In the analysis results, the Gangnam 3-gu emerged as the region with the highest housing prices. It was observed that the longer the elapsed years, the more the anticipation of reconstruction was reflected in housing prices for older apartments. Additionally, a strong preference for convenient living facilities and an excellent educational environment was evident, indicating a dual focus on residential convenience and investment purposes.
 On the other hand, the Nodogang region had the lowest housing prices. The elapsed years were found to be significant only beyond a certain generational threshold. Preference for living convenience facilities showed contrasting results compared to the Gangnam 3-gu. Furthermore, the importance of proximity to subway stations was highlighted, indicating anticipation for reconstruction alongside the significance of convenient public transportation in this region.
 The Mayongseong region fell into the category of higher housing prices. It consisted relatively of newly constructed apartments, and the preference leaned more towards a pleasant residential environment rather than anticipation for reconstruction. This area exhibited a lower connectivity to subway stations, and there was a preference for a close proximity to local markets. In terms of pursuing residential convenience, it displayed similarities to the Gangnam 3-gu.

Paratransit service quality modeling reflecting users' perception-A case study in Dhaka, Bangladesh

Increasing usage of private cars and low service quality of public transport is an acute problem in many developing cities. The prerequisite is to meet the mobility needs, especially for low-income people, to ensure adequate capacity by the service provided. Paratransit is an indispensable mode of public transport, especially where the mass transit system is insufficient. Rapid increase in urban population, per capita income along existing transport infrastructure has stimulated their usage as a cheap and convenient public transport mode. Quality of service is considered as one of the most significant means to assess transit performance. To observe the performance of public transportation in roadway systems, overall passenger perceived service quality (SQ) has always been the most significant means of measurement. This research aims to establish a relationship between SQ variables describing the service of paratransit by Structural Equation Modeling (SEM) based on users' perceptions. An interview survey was conducted off-board to 2025 paratransit users at twenty paratransit routes in Dhaka metropolitan area (Bangladesh). Results show that the attribute of integration with supporting modes has the highest loading, inferring it as the most significant aspect of SQ. Attributes loading value may be explained according to the importance perceived by the users. Several SE models were developed using 21 service variables from 2000 questionnaires. Upon developing different models, the best model with three latent constructs was identified as the main characteristics for explaining the entire set of physical and service performance elements of the paratransit service. Three latent constructs were ‘Quality of transport’, ‘Transit performance’ and ‘Service quality’. Among 21 SQ variables, ‘Security of passenger’, ‘seat comfort level’, and ‘riding safety’ have been found to impart the greatest influence on the overall perceived SQ. The study findings support the data collected from paratransit users. This study may help the paratransit operators to determine variables that are decisive for SQ and their relation with the overall perceived SQ by the users. Understanding SQ variables, influencing passenger perception makes it easier to design and deliver good quality service.

An Implementation Framework for On-Site Shield Spoil Utilization—A Case Study of a Metro Project

A majority of metro projects have been constructed to reduce urban traffic congestion and to improve the convenience of public transportation, but these projects also produced a significant amount of engineering slag and mud. The shield construction method could improve the efficiency and safety; this technique has been frequently used in tunnel excavation projects. However, the spoil produced during the shield construction is challenging to deal with. In literature, though there has been an increasing number of studies on the technologies of utilizing shield spoil, the on-site utilization of shield spoil is still a subject of little research. This study introduced an implementation framework for the on-site utilization of shield spoil based on successful case experiences. It aims to assist project managers in efficiently implementing on-site resource utilization projects and to address the gaps in the relevant field. A case study was conducted in the Shenzhen Metro Line 13 North Extension Project; this study collected data through six semi-structured interviews and field research, analyzed the data, and constructed a framework using thematic analysis and focus group discussions. The three components of the implementation framework are project planning, project construction, and project closing, and each section describes what must be accomplished during that phase. Additionally, three recommendations—(1) combining intelligent technology to optimize the existing equipment, (2) utilizing lean technology in project execution, (3) establishing strategic partnerships with construction waste recycling enterprises—are also made for the development of the shield spoil utilization project. This study uses the Shenzhen Metro Line 13 North Extension Project as a model to theoretically underpin future research on shielding spoil on-site during resource utilization projects and to achieve the repeatable promotion of shield spoil utilization technology in Shenzhen.

Structural behavior of full‐scale precast posttensioned girder with substandard transverse reinforcement–experimental and analytical study

AbstractRapid expansion of developed cities create problems mainly attributed to traffic congestions. Recently, Bangkok has faced rapid growth and the expanded neighborhoods require convenient public transport to be linked with central Bangkok and other parts of Thailand. Monorails can be an exceptional alternative to conventional skylines and subways thankfully to their excellent climbing abilities, lower noise, shorter constructions periods, and their capabilities to be adapted within limited spaces. Recently, Mass Rapid Transit Authority adopted monorail system to facilitate public in Bangkok's expanding neighborhoods. A four‐span continuous posttensioned girder system has been proposed for the straddle monorail system. Current study focuses on the structural response of full‐scale precast posttensioned (FPP) end girders in the proposed monorail system. Results suggested that the girder remained undamaged under service load while exhibiting a linear load versus vertical deflection response. Failure under ultimate load was accompanied by crushing of concrete, buckling of compression longitudinal bars and posttension tendons at the midspan. Further, experimental rosette strains suggested that concrete strains remained well below the ultimate of strains in the vicinity of high shear zones of the girder. Therefore, these results augment that the proposed design practice is safe against shear and the proposed girder can safely be used as the end girder in four‐span straddle monorail system. Nonlinear analysis of the girder was performed using advanced tool for engineering nonlinear analysis by adopting its built‐in constitutive laws for concrete and steel reinforcement. Predicted analytical response of FPP was in good agreement with experimental results in terms of load‐deflection curves, crack patterns, and failure mode.

Features of Development of Route Networks of Public Urban Passenger Transport in Russian Monotowns: the Case of the City of Nizhnekamsk

Currently, improvement of public transport of general use is among priority areas for development of urban transport systems. Convenient public transport routes, combined with modern rolling stock and a developed transport infrastructure, allow solving most transport problems and ensure high mobility of residents and guests of a city. The objective of the research, main results of which are described in the paper, was to build an efficient urban public transport network in monotowns of Russia to ensure sustainability of functioning of public passenger transport intended for general use. The article presents an option for solving the problem of functioning of public transport in single-industry towns. Very often, in such cities (with enterprises pronouncedly influencing urban planning), there are two mutually exclusive transport networks, namely, municipal one and contracted one (contracted by an enterprise and intended for shift rotation). As a result, contracted routes are not optimal, municipal carriers suffer losses, transport companies do not meet the schedule, switch to a less capacious type of vehicles, and consequently people are dissatisfied with the work of public transport in the city. To solve these problems, it is proposed to combine the municipal and contracted networks into a single transport network of the city.
