Teleworking has been disseminated throughout the world with the spread of the coronavirus, which has instigated changes in our workstyle. To better understand teleworking, a web-based questionnaire survey was conducted at the end of March 2020. The survey included 3,500 respondents who worked and lived in three metropolitan areas in Japan. In this study, the choice and intention to telework were analyzed while considering the trade-off between commuting and teleworking as well as incorporating the cost and benefit of both commuting and teleworking. The commuting cost includes travel time, travel-related risks (contracting COVID-19), and satisfaction with travel scale. For the cost of teleworking, risks of ICT use were incorporated. The work satisfaction with teleworking compared to office-based work was measured by incorporating social presence as a predictor. Further, socioeconomic attributes such as age, family composition, type of work, and type of industries were considered. The binary probit and ordered probit model were applied to the analysis. The estimation results showed that risk perceptions, travel satisfaction, and work quality of teleworking considerably affected the individual's preference to telework. The findings are expected to provide valuable insight into urban planning and transportation system designs resistant to the risk of infectious diseases.

Recognising the factors that shape the public acceptance of hydrogen refuelling facilities is essential for gaining social support for the widespread implementation of hydrogen infrastructure. This study applies a cross-national research perspective to investigate the public acceptance of hydrogen refuelling facilities using stated-preference survey data. Moreover, multidimensional explanatory variables encompassing hydrogen energy awareness levels, hydrogen refuelling station configurations, residential characteristics, car ownership and use, and sociodemographics are used to interpret public acceptance. The data revealed that 21.1 %, 45.5 %, and 31.5 % of the respondents in Japan, Spain, and Norway expressed support for such facilities near their residences, respectively. An important discovery was the validation of nonproportional odds in acceptance measurements across countries, which challenges the conventional assumptions of parallel regression and suggests that distinct behavioural determinants shape positive, negative, and neutral attitudes. Consequently, a generalised ordinal logistic regression approach was applied to identify the determinants of varying acceptance levels and mitigate the biases from nonproportional odds. In addition to identifying facilitators and hindrances, the results highlight several predictors with polarising effects. These findings provide public feedback for enhancing the planning of hydrogen infrastructure and offer potential pathways for hydrogen risk communication and policymaking.

Residential dissonance and changes in travel satisfaction: Evidence from Japanese dual-earner couples 査読有り国際共著

134 巻 2024年9月

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：Transportation Research Part D: Transport and Environment

This study examined the extent to which residential dissonance affected changes in travel satisfaction before and during the pandemic. We conducted a gender-specific analysis using data from 540 spouses in 270 households in Greater Nagoya, Japan. The results showed that for women, the negative dissonance of accessibility and neighborhood socialization may deteriorate commute satisfaction, while the negative dissonance of car alternatives may decrease non-commute satisfaction. For men, the positive dissonance of aesthetics decreased non-commute satisfaction. Moreover, men who decreased car use reported a decrease in commute satisfaction. Men who cycled less frequently experienced a decrease in non-commute satisfaction, while women who cycled more frequently reported an increase in non-commute satisfaction. The findings suggest the importance of gender in travel satisfaction and suggest that intervention strategies should be tailored to address the needs of specific population subgroups, such as working women in dual-earner households.

As green hydrogen plays an increasingly pivotal role in shaping sustainable economies and society, understanding public acceptance of hydrogen becomes imperative for fostering social support towards hydrogen energy transitions. This study employs a survey-based structural equation modelling method to analyse public perceptions and acceptance of hydrogen technology, fuel cell vehicles, and refuelling infrastructure based on technology acceptance theory. The results highlight the positive impact of the perceived usefulness of hydrogen energy and refuelling stations on individual acceptance levels. A notable discovery reveals that perceived risk consequences significantly influence individuals’ acceptance of nearby refuelling infrastructure, whereas perceived risk likelihood does not. Moreover, this study establishes psychological connections among diverse dimensions of hydrogen acceptance: technology acceptance is found to correlate positively with acceptance of refuelling infrastructure, indicating a pathway for cultivating public acceptance from cognitive to practical levels. The acceptance of hydrogen fuel cell vehicles exhibits mediating effects on this pathway, signifying mutual benefits for stakeholders in promoting hydrogen mobility and establishing refuelling infrastructure.

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：Applied Energy

With increasing concerns about recent hydrogen-related accidents in leading countries applying hydrogen energy, maintaining public trust in hydrogen infrastructure is crucial for advancing energy transitions. This study investigates how individuals aware and unaware of hydrogen-related accidents perceive the risk of hydrogen refuelling facilities in Japan. The comparative analysis reveals that accident awareness significantly increases public apprehension by amplifying perceived accident probabilities and consequences. Specifically, accident-aware individuals value their subjective understanding of hydrogen knowledge more than objective knowledge when it comes to trusting hydrogen technologies. The direct impact of positive affect on alleviating risk perceptions is found to be counteracted by accident awareness. In terms of behavioural outcomes, this study confirms individuals' inclination to seek information based on their perceived risk. People are more eager to acquire risk preparedness information when they perceive the potential consequences of undesired events as significant. In contrast, the perceived likelihood of risk accidents does not exhibit such a significant relationship. The findings offer valuable insights for recognising circumstances in which the communication of risk preparedness initiatives becomes crucial in the aftermath of accidents.

The COVID-19 pandemic and the resultant preventive measures worldwide have accelerated a change in the way millions of people work. Telework became necessary to prevent the spread of coronavirus and reduce office workers’ health risk. The change in employees’ workstyle may directly impact commuters’ travel behavior, which affects individuals’ residential area choices and companies’ office location choices, ultimately affecting urban development and transportation infrastructures. This research aims to investigate preferences for telework among Japanese employees and, in hybrid workstyles, identify the factors that affect the best trade-off between commuting-based work and telework. A web-based questionnaire collected data which was analyzed using ordered probit modeling. Results revealed that 25% of non-telecommuters want to switch to telework and that the number of workers who want 100% telework increased from 4.9% to 8%. Regression analysis showed a strong influence of socioeconomic and demographic characteristics on the choice between commuting and ICT-based work. Results of this study make it possible to understand office workers’ intentions to work remotely and predict how this will affect economic activity distribution within urban areas. It is also possible to consider an actual case of the implementation of ICT infrastructure for specific segments of society.

Hydrogen fuel cell vehicle (HFCV) adopters need to continue their vehicle ownership in the subsequent years to achieve the HFCV-related targets set by the Japanese government. In this study, we explored the discontinuance rate of HFCV ownership through a questionnaire survey conducted among HFCV adopters in Aichi Prefecture, Japan, who were wanting to continue or discontinue their ownership. Results showed that the discontinuance rate was remarkably high. Approximately 50% of the private HFCV adopters, who purchased their vehicles between 2014 and 2020, wished to discontinue their HFCV ownership owing to factors such as driving range, vehicle performance, future viability, fuel tank safety, and density of stations. Furthermore, we showed that the discontinuance trend was correlated with the dissatisfaction of HFCV adopters with the driving range and future viability. As a result, they foresee a bleak future owing to the sparse refueling stations network and higher purchase price compared to other vehicle powertrains such as electric and hybrid vehicles. Therefore, to reduce the discontinuance rate and keep HFCVs in the market, Japanese stakeholders must address the concern of HFCV owners.

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：Asian Transport Studies

To support car use reduction in Japan, this study investigates the possible relationships between environmental concerns and car use. Covariations, unidirectional effects, and reciprocal effects were examined using structural equation models with the data from 900 respondents collected in Nagoya, Japan through a web-based survey. A significant negative correlation between environmental concerns and car use was found, whereas a causal effect of environmental concerns on car use was not verified. In addition, socio-demographic variables could explain less than 15% of the variances of environmental concerns and car use. Hence, reducing car use by promotion campaigns aimed at raising awareness of ecological problems is not suggested. Instead, factors other than environmental concerns and common socio-demographic characteristics may have better explanatory potential for car use. From a model specification perspective, we suggest future studies in this domain to explicitly consider the reciprocal relationships between hypothesized factors.

The aim of the present study was to investigate the basic cross-cultural differences in the aberrant driving behaviors of Japanese, Chinese, and Vietnamese drivers. Overall, the Vietnamese drivers reported more instances of all four types of aberrant behaviors on the road as compared to the drivers from the other two countries. On the contrary, the fewest aggressive violations were reported by the Japanese drivers. An analysis of variance was also performed; the results indicated significant differences in the aberrant driving behaviors of drivers from the three countries. The test statistics indicated there are significant differences between the drivers from the three countries in terms of the Driver Behavior Questionnaire (DBQ) items. Finally, the results of a confirmatory factor analysis revealed that the four-factor model structure of the shorter version of the DBQ used in this study was valid for Chinese drivers but only partially valid for Vietnamese and Japanese drivers.

This paper investigates attitude of respondents towards a new transportation alternative namely cooperative ride system (CRS) for elderly people using 1052 samples collected in Asuke, Japan. A multinomial logit (MNL), nested logit (NL) and NL with consideration of covariance heterogeneity (COVNL) across decision makers were estimated. Additionally, three COVNL models with different transformation functions (probit, logit and C log-log) were tested for comparison. The results indicate that by incorporating the covariance heterogeneity, the COVNL model results in dramatic improvements in terms of better fitting to the data and behaviorally representing the choices of decision makers. Moreover, among three transformation functions, the C log-log function is the best while the probit function is the worst ones for data fitting. Evidence from model estimation results shows that the potential volunteer drivers for the CRS are the people living in a single household, currently using cars and having more frequencies of driving and traveling. Most importantly, the elderly people, whom the CRS is proposing for, are found to significantly participate as the riders. Furthermore, females, students and the people earning low annual income possibly join as the riders. Interestingly, the people who gained experiences of being the volunteer drivers or riders have higher willingness to take part in the CRS.

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：Eastern Asia Society for Transportation Studies

A large body of evidence supports that driving stress both directly and indirectly leads to traffic accidents. Therefore, driving stress is an important issue to reduce traffic accidents. The aim of this study was to evaluate the impact of roadway conditions and land-use on driving stress among professional drivers and to give some suggestions to reduce the driving stress. Multiple indicators multiple causes (MIMIC) model was used to empirically investigate which variables of the roadway condition and land-use affected the driving stress among drivers in Yangon, Myanmar. Standard deviation of normal to normal RR intervals (SDNN), Square root of the mean squared differences between successive RR intervals (RMSSD), Percentage value of consecutive RR intervals that differ more than 50 ms (pNN50), Baseline width of the RR interval histogram (TINN), Balance between the sympathetic nervous system activity and the parasympathetic nervous system activity (fast Fourier transform) (LF/HF (FFT)) and Balance between the sympathetic nervous system activity and the parasympathetic nervous system activity (Autoregressive) (LF/HF (AR)) are used as driving stress indicator. The results suggest that certain roadway conditions reduce driving stress. Specifically, using roundabouts and traffic lights at intersections to control traffic and increasing the number of lanes are the effective ways to reduce driving stress. However, roundabouts rather than traffic lights are more efficient. Conversely, industrial zones are associated with an increase in driving stress.

Traffic accidents result in more than 1.2 million deaths worldwide per year, especially in developing countries. Therefore, road safety is a major issue in these countries. Many researchers found that traffic accidents occur mainly because of driving stress and driving behavior. There are few studies on driving stress in developing countries, particularly in Myanmar. The purpose of this study is to investigate the effect of roadway conditions on driving stress in Myanmar by using heart rate variability (HRV). The study used two polar watches V800, a heart rate sensor H7, and a video camera to collect data and carried out time-domain and frequency-domain analysis of HRV by using the Kubios HRV analysis software. The results showed that drivers experience different driving stresses depending on roadway conditions. In particular, highly crowded places and those requiring attention such as mixed roads, lane-changing points, jaywalking places, rough and bad pavements, traffic congestion areas, and flyover are the most stressful segments along the roadway for drivers.

We analyzed the impact of demographic variables, driving stresses in the real world, driving behaviors related to stress, and unsafe driving behaviors on accident involvement among professional drivers in Myanmar. The aim of the study is to investigate whether driving stress as well as demographic variables can be linked with driving behaviors and lead to traffic accidents. Structural equation modeling (SEM) is developed to represent the relationship, and Yuan-Bentler residual-based test statistics are used to validate the model structure, as the sample size is small. The results confirmed that driving stress as well as demographic variables affect driving behaviors and lead to traffic accidents.

This paper examines the influences of environmental consciousness and attitudes to transportation on electric vehicle purchase intentions. A multiple-indicators?multiple-causes model and a latent-class nested logit model with two segments were estimated using data obtained through a web-based questionnaire survey in the Chukyo Area of Japan. Results reveal that both environmental consciousness and attitudes to transportation significantly affect an individual's EV buying intentions. Specifically, for the segment of mostly auto-dependent householders, environmental consciousness has strong negative relationships with intention to buy an EV as a replacement. The results provide insight for the design of policies aiming at promoting the adoption of EVs.

本研究では，2009年に名古屋市にて実施された，コミュニティサイクルシステム（CCS）の社会実験によって得られたデータから利用状況を把握することが1つめの目的としている．さらに，CCS実現のキーポイントとなる適切なステーション配置の設計に貢献することを2つめの目的とし，ステーションごとの潜在需要を含む貸出頻度モデルを構築し，どのような場所にステーションを配置すべきかを分析する．その結果，名古屋都心部の土地利用や都市機能の配置が，CCSの利用目的にも如実に表れており，ステーション配置を検討する際には，沿道状況や土地利用状況を考慮することが利用を促進する上で重要であることが分かった．
