Summary: This study explores how purchasing intangible services online affects travel distance and mode choices in Beijing, China. Findings indicate that people tend to travel farther and switch from nonmotorized modes to motorized modes due to online purchases. Factors such as lower living costs and greater satisfaction with online purchases are linked to increased travel distances and mode choice changes.

Summary: The COVID-19 lockdown has influenced activity-travel behavior and the adoption of ICT-based alternatives. During the lockdown, there was a preference for home meal preparation over online ordering and a reluctance to engage in in-person shopping. Respondents prefer to work from home if they have adequate access to home office materials. Individuals with children must consider suitable childcare before returning to work.

Summary: This paper uses an affordance lens to explore parasocial interactions and relationships between travel live streamers and viewers. The findings demonstrate that travel live streaming affordances provide opportunities for parasocial interactions and the development of acquaintances and conflicts. The study contributes to parasocial investigation and affordance literature, and introduces a novel methodological approach for capturing and analyzing live streamed video footage. Practical implications are discussed for live streamers, destinations, and platforms.

Summary: This paper proposes a tool for objective evaluation of organisations' information and communication technologies (ICT) infrastructure development level: Composite Indicator of the Organisational Information and Communication Infrastructure-CIOICTI. It consists of six linear and non-linear indicator components, each designed to evaluate one specific aspect of ICT development, based on the weighted sum principle. The proposed composite indicator can be used as an objective tool for researchers and practitioners to assess the level of ICT development for benchmarking with other companies, planning organisational changes or assessing infrastructural requirements for planning and implementation of ICT related projects in a business organisation.

Summary: This study presents a global framework for transport, health, and health equity by synthesizing 94 urban transport and health frameworks. The framework highlights the importance of health equity, which is often neglected in existing frameworks. By addressing key components identified in a scoping review, this framework can guide the work of various agencies, such as the World Health Organization, in promoting healthier and more equitable transport decision-making globally.

Summary: This research investigates the impact of information and communication technology (ICT) on energy security using panel data from 66 countries between 1996 and 2019. The findings reveal a negative influence of ICT on energy demand and security, with financial development and technological progress serving as the main channels of impact. While human capital significantly affects energy security, it does not mediate the relationship between ICT and energy security. The study also observes an inverted U-shaped relationship between ICT and energy security with economic risk as a threshold variable, with ICT initially increasing energy security at lower levels of risk but weakening it beyond a certain level. Similarly, the impact of ICT on energy security fluctuates over time.

Summary: Innovations in transportation and communications technologies have an impact on the development of cities and people's mobility. The study aims to understand the factors influencing modal choices and how the use of ICTs and personal opinions and attitudes influence decision-making. The results show strong correlations between mobile app usage, travel attitudes, personal characteristics, and transportation modes. However, there is doubt regarding the effectiveness of ICT in promoting sustainable transportation. Social incentives may play a significant role for certain individuals.

Summary: This study uses five cross-sectional travel surveys conducted in California from 1992 to 2018 to examine the factors influencing individuals' self-reported measures of life satisfaction. The findings show that longer commute times, mobility limitations, and perceiving travel as a waste of time are negatively related to life satisfaction. Additionally, the study reveals that GDP per capita and the macro-scale unemployment rate have significant impacts on life satisfaction.

Summary: The experiment simulating life with personally owned, fully autonomous vehicles showed that AVs can increase travel miles but may have detrimental effects on the transportation system. Households with mobility barriers or less auto dependency saw the highest percentage increase in VMT, while higher VMT households and families with children had the smallest increase.

Summary: By utilizing travel diary data from the 2017 NHTS Georgia subsample, this study addresses critical issues related to analyzing complex work journeys and discusses the importance of defining commute anchors based on purpose and location. Comparing two methods for determining commute distance, it was found that using a modeled counterfactual simple commute resulted in an average 63% higher estimate of complex commute distance compared to using the last leg method. This suggests that the last-leg method may underestimate Georgia's annual commute distance and is not accurate for measuring work travel, especially for populations such as women who are more likely to chain trips during their commutes.

Summary: This study provides a review of literature on modal shifts in the US and other countries, revealing that shared e-scooters may be a good strategy for reducing car dependence in many US cities. However, the extent of integration between shared e-scooters and public transit varies by city, suggesting the need for technology, regulations, and incentives to ensure successful integration.

Summary: This study examines the changes in online and in-store grocery shopping in California during the COVID-19 pandemic. It found that there was an increase in online grocery purchases among consumerist individuals, while financially conservative individuals and those facing financial struggles showed a decrease. People bought more items per purchase in stores, visited stores less frequently, and transitioned from dining out to cooking at home. Those who enjoy driving and being physically active continued visiting stores more often. Social media use and health concerns influenced shopping patterns, and sociodemographic factors such as household income and race also impacted these changes.
