This study proposes an integrated theoretical framework to comprehensively examine the satisfaction and subjective well-being of ridesourcing travelers. A total of 1370 survey responses from China were empirically examined, using partial least squares structural equation modeling and multigroup comparison methods. The findings show that platform sa...
Shared autonomous vehicles (SAVs) have potential benefits for the society and environment. This study constructs a novel framework to investigate the combined effects of the external environment and personal attributes on SAVs adoption. Using questionnaire data from 669 Chinese consumers, a range of methods, including partial least squares structur...
This study introduces “Daily Activity Duration Tolerance” as the duration whereby affective well-being (i.e., happy, tired, stressed, sad, pain) deteriorates as a function of activity- and individual-level factors. A panel survival analysis is conducted on 9618 activity episodes performed by 353 residents of the Minneapolis-St. Paul metropolitan ar...
Insights into tourist travel behaviours are crucial for easing traffic congestions and creating a sustainable tourism industry. However, a significant portion of the literature analysed tourist travel behaviour by predefined tourist trip chains which result in the loss of more representative classification. Using tourist travel survey data from Nan...
This study investigates how the use of sustainable transport modes relates to travel satisfaction (general evaluation of travel) and travel affect (emotions during travel) in car-dependent compact cities. Thereby, the study provides evidence on sustainable mobility and travel-related well-being in a context of compact urban form but inadequate prov...
This study aims a more thorough understanding of individuals' motivations and determinants of working from home (WFH) at various phases of the pandemic. To achieve this research goal, we analyze attitudes towards WFH, the profiles of various types of workers engaged in WFH, and the determinants of the current and future expected frequency of WFH am...
In recent years, the level of acceptance of autonomous vehicles (AVs) has changed with the advent of new sensor technologies and the proportional increase in market perception of these vehicles. Our study provides an overview of the relevant existing studies in order to consolidate current knowledge and pave the way for future studies in this area....
Ridesharing is a shared mobility service in which passengers and drivers with similar origins and destinations are matched to travel in the same vehicle. This service utilises unused seats in vehicles and multi-passenger rides to reduce the cost of travel. To promote ridesharing, both service providers and policymakers should carefully analyse pass...
The COVID-19 pandemic illustrated that undirected travel (UT), or trips taken for their own sake, can partly compensate for a reduction in destination-based trips due to governmental regulations. Consequently, UT (in general, but particularly during the pandemic) may be especially satisfying and therefore important to subjective well-being. However...
The positive utility of travel (unrelated to the destination) and travel satisfaction have been discussed in travel literature, but a research gap exists in comparing if and how travel benefits might differ among commuting, shopping, leisure, and undirected trips (those without a destination, undertaken for the purpose of the trip itself). By speci...
This study aims to link two closely related domains in literature – travel behavior and tourism. Travel behavior studies partly aim to improve travel satisfaction by exploring its relationships with overall and domain-specific life satisfaction. Tourism studies, on the other hand, focus on improving the attraction and sustainability of tourism dest...
Research on the relationships between travel-related attitudes and travel behaviour has recently been reinvigorated by new theorizing as well as new empirical models. While traditional theories assume a rather static role of attitudes, i.e. acting as stable predispositions that cause behaviours in a unidirectional manner, recent models assume that...
This paper provides causal inference on how transport intervention affects moderate-to-vigorous physical activity (MVPA) and walking among older adults using a natural experiment of a new metro line in Hong Kong. A longitudinal survey of 449 cohort participants was collected before and after the metro operation. Treatment groups live within a 400m...
Due to financial constraints, it can be expected that low-income groups may encounter transport poverty (e.g., limited travel mode options, low accessibility to workplaces) and have poor health conditions, therefore making them feel unsatisfied with commuting. However, few previous studies have examined this assumption. Using data derived from a fa...
This research regards the COVID-19 pandemic as a major life event with the ability to affect daily activity-travel behavior, and investigates if specific activity participation (work/study, shopping, social contact, free time) is associated with different travel modes (walk, cycle, car, public transportation), with attention paid to residential nei...
Recently, a growing body of literature has focused on the role of daily mobility on subjective well-being (SWB). What is less well understood is the temporal effect of commuting on SWB/life satisfaction. To date, most studies addressing this temporal effect consider the impact of a residential relocation and not many studies reflect on the impact o...
This study is the first to empirically analyze motivations for taking undirected travel (UT) trips, or travel without a destination (as opposed to derived trips) undertaken for the purpose of the trip itself, as the determinants and characteristics are largely unknown. The overall research objective is to explore UT motivations in terms of demograp...
Previous studies have indicated that factors such as the built environment, attitudes and past behaviour can influence travel behaviour. However, the possible effect of travel satisfaction on travel mode choice remains underexplored, despite many studies focusing on travel satisfaction over the past years. It is likely that individuals experiencing...
Bike-sharing offers a convenient feeder mode for connecting to public transport, which helps to address the last-mile problem. However, few studies have examined the nuanced relationship between the built environment and the integration of free-floating bike-sharing (FFBS) with urban rail transport (URT). Drawing on weekly records of 3.12 million t...
For decades, accessibility – i.e. the ease of reaching destinations – has been an important concept in transport planning, resulting in many studies trying to measure it and put it into practice. Also walkability, a mode-specific type of accessibility referring to how easy it is to walk (to destinations) received increased attention in the last two...
Many studies have found that both the chosen travel mode and travel duration have a strong effect on travel satisfaction. However, travel mode and duration are often related with each other, as active trips often have shorter durations than trips with motorized modes. As a result, the effect of travel mode choice on travel satisfaction may be atten...
Metros constitute an important form of public transport in large cities throughout the world. Because metro transport encompasses long distances and large areas, many metro passengers must transfer to other transport modes to complete their journeys. This paper will review the recent literature on metro-related transfers and will summarize and disc...
Although the majority of literature explains travel satisfaction by examining trip determinants, the interaction between travel satisfaction and satisfaction with other life domains has been analyzed less frequently. Accounting for satisfaction with other life domains is nevertheless important because the effect of trip characteristics on travel sa...
Introduction
Increasing attention has been paid to accessibility and equity during the last two decades. Yet, despite the proliferation of studies investigating accessibility and equity from the perspective of the younger generation, only modest progress has been made in embedding a temporal perspective and targeting health services for older adult...
Numerous studies have investigated the travel effects of online purchases. However, compared to tangible goods (e.g., books, electronics, and clothes), very limited attention has been paid to online purchases of intangible services (e.g., hairdressing, dining out, and visits to movie theatres, zoos, and local theme parks). Utilizing data obtained f...
Via the internet, people can easily access high quantities of (information on) intangible services (e.g., dining out services, movie theater visits), often at low(er) prices. Therefore, purchasing these services online likely stimulates consumers to make extra trips for on-site consumption, thus posing a possible challenge for transportation system...
Using data derived from 597 face-to-face interviews with ride-hailing users in Chengdu (China), we examined the influence of ride-hailing on travel frequency and mode choice and further analyzed what the main determinants for these are. The results indicate that 16.8% of the respondents increase their frequency of trips because of the adoption of r...
Transport-related residential self-selection indicates that people try to live in a neighbourhood in line with their travel preferences and needs. Although studies have found that travel attitudes are mostly aligned with urban form characteristics of the residential location, no studies have explored whether people are actually able to travel in th...
It is widely acknowledged that e-shopping has considerable effects on e-shoppers' travel behavior. Therefore, it is valuable to investigate the built environment effects on online shopping, which can help clarify whether land use policy is effective to manage online shopping and further moderate travel demand. However, this issue has not been fully...
A considerable number of empirical studies have explored the effects of information & communication technologies (ICT) on travel in recent years. In particular, the most attention has been paid to whether the use of ICT increases or decreases trip frequency (i.e., substitution or complementarity effects). However, the subject of whether or how trav...
Despite having the potential to improve subjective well-being, satisfaction with undirected travel, or travel for its own sake (e.g. taking a walk, bike ride, or joy ride), has not yet been empirically investigated. Using mean-comparison and generalized linear regression models, this study analyzes 1579 undirected trips made by 852 respondents to a...
Numerous studies have found that travel attitudes might not only affect travel behavior, but also the residential location choice as people might choose a residential location based on their travel preferences and needs (i.e. transport-related residential self-selection). However, it might also be possible that the residential location and travel b...
In this study, we investigated travel captivity from the perspective of travel satisfaction. Using survey data from 565 commuters in Portland, Oregon, we compared satisfaction with the most recent commute trip (using the chosen mode) and hypothetical commute satisfaction if using an alternative mode. The difference in travel satisfaction between th...
During the COVID-19 crisis, a series of measures were taken to restrict travel and social activities outside the home in order to curb the pandemic and ameliorate its negative effects. These unprecedented measures have had a profound impact on the number and purposes of trips and modes of travel. In China, although the pandemic is now generally und...
Many studies analysing the relationship between attitudes and travel behaviour have found that travel attitudes have an important impact on travel mode choice. More recently, studies focusing on how people experience travel have shown that travel satisfaction is influenced by the chosen travel mode. The desire and intention of using a travel mode –...
Reducing car use is commonly considered as a potential strategy to reduce transport-related problems such as traffic congestion and air pollution. The increasing use of online shopping may potentially replace shopping trips, thus possibly reducing car use. However, car owners – compared to non-car owners – can more easily visit physical stores and...
Although previous studies have explored how satisfied people are with their travel, the link with the built environment and available travel options is unclear. This research investigates whether travel options influence how commute time satisfaction relates to the built environment. First, profiles among commuters in terms of commute time satisfac...
The COVID-19 pandemic lockdown undeniably impacted travel behavior. It is assumed that directed (commute and non-work) trips reduced following reduced out-of-home activities. This study analyzing 764 respondents in Flanders, Belgium, explores whether undirected trips, or travel for the purpose of travel itself, increase as compensation or to ‘get o...
Many studies have demonstrated that the built environment has a strong impact on people's travel mode choice. However, the built environment also influences elements such as travel distance and car ownership, which might be the true predictors of which travel modes are chosen. In this study, we analyse the effects of changes in residential neighbou...
Understanding the relationship between the built environment and walking among older adults could offer important insights into land use and transport policies which seek to promote active ageing. However, most previous studies have explored global relationships, i.e. the effects are averaged or assumed to be constant over the region of interest. I...
Continued globalisation and urbanisation-resulting in the increase of inter-and intra-city trips-present an important challenge to the environmental, economic, and social sustainability of our society. Most efforts currently trying to resolve the issues of emissions, energy, and the health and wellbeing impacts of transport relate to either (i) imp...
Residential dissonants, residents who are not satisfied with land use patterns in their neighbourhood, are a threat to transit-oriented development (TOD) policy because of their unsustainable transport choices. However, it is not known if their level of dissatisfaction is reduced in TODs, and if so, the time duration it takes. This study tracks dis...
Background: With the rapid demographic shift towards an ageing society, it is a concerted effort to facilitate elderly’s access to healthcare in order to maintain and improve their quality of life. In China, hospital care services dominate the healthcare market, which requires a better understanding of accessibility to hospitals in order to rationa...
This introduction to the special issue on travel, health and well-being is subdivided into three parts. In Section 1 we provide a summary of existing literature analysing how health and well-being are related with transport and travel behaviour. An overview and short descriptions of the studies included in this special issue are given in Section 2....
Previous studies often assume a pre-specified relationship between walking and the built environment. Using data from 702 older adults in Nanjing (China), this study employs a random forest method to scrutinise the refined associations between the built environment and walking time among older adults, while controlling for socio-demographics. Resul...
E-shopping for intangible services (e.g., eating out services, hairdressing, and visits to movie theatres) refers to searching and paying for services online, but it requires e-shoppers to travel to use these services. In theory, e-shoppers' search space via the internet is less constrained by spatial attributes. As a result, spatial attributes may...
In this review paper, we reconceptualise the relationships between travel-related attitudes and behaviours using (and considering the applicability of) Festinger’s cognitive dissonance theory. According to this psychological theory – developed in the 1950s and widely used ever since − a dissonance between attitudes and behaviour can result in feeli...
The use of public transport is critical for Visually Impaired People (VIP) to be independent and have access to out-of-home activities. Despite government policies promoting accessible transport for everyone, the needs of VIP are not well addressed, and journeys can be very difficult to negotiate. Journey requirements can often differ from those of...
The spread of the COVID-19 virus has resulted in unprecedented measures restricting travel and activity participation in many countries. Social distancing, i.e., reducing interactions between individuals in order to slow down the spread of the virus, has become the new norm. In this viewpoint I will discuss the potential implications of social dist...
The desire to use public transport, or use it more frequently, can be an important indicator of people's intention to travel by public transport. However, the desired and relative desired travel amount (wanting to travel less or more) in the context of public transport use has not yet been analyzed. In this paper, we examine the relationship betwee...
In this introduction to the special issue on travel and residential change, we provide an overview of the literature on the interaction between travel behaviour and dynamics in the residential context, focusing on (i) the effect of travel on people's intention to relocate, (ii) the effect of travel on the residential location choice, and (iii) the...
Introduction
Active travel (walking and cycling) is increasingly being recognised as a potentially effective means of increasing physical activity levels and thereby contribute to physical and mental health. To date, however, much of the empirical evidence related to the health benefits of active travel is based on cross-sectional data. As such, th...
Transportation's effects on health and well-being are widely recognized. In the near future, autonomous vehicles (AVs) are expected to revolutionize transportation options and ways of travel. Consequently, the effect of AVs on population health and well-being is a crucial topic of interest for transportation policymaking, one that has received comp...
Many studies have indicated that commute satisfaction is affected by commute time. However, the dissonance between people’s actual and ideal commute time and its effects on travel satisfaction have not been adequately explored in previous research. By using survey data from Xi’an, China, this study examines whether respondents travelling with an id...
Previous studies mostly indicate that young adults travel less by car compared to their older counterparts, partly due to postponing driving license holding and car ownership. Furthermore, these young adults might also prefer living in urban, low-traffic neighborhoods, further reducing car use. In this study we analyze the residential location choi...
This review provides a critical overview of what has been learnt about commuting’s impact on subjective wellbeing (SWB). It is structured around a conceptual model which assumes commuting can affect SWB over three time horizons: (i) during the journey; (ii) immediately after the journey; and (iii) over the longer term. Our assessment of the evidenc...
Mobility-as-a-Service (MaaS) has received widespread attention over the past couple of years amongst scholars, businesses, policymakers and mainstream media. Most coverage is oriented towards its possible gains for traveling individuals and the travel industry, while still lacking conceptual clarity and sufficient detail about its potential accepta...
Transport researchers conceptualise residential mobility as a BE intervention because there is the potential for residents to be exposed to a different urban form following relocation. Residential mobility studies therefore overcome the weaknesses of cross-sectional studies in establishing causal links between urban form and travel behaviour. Howev...
The importance of attitudes in the relationship between travel behaviour (TB) and the built environment (BE) has been the subject of debate in the literature for about two decades. In line with the Theory of Planned Behaviour, attitudes-which affect behaviour-are generally assumed to be constant. However, it is plausible that attitudes can change,...
Previous studies indicate that travel satisfaction is affected by elements such as travel mode choice and trip duration. However, how people's satisfaction levels with travel adapt after changing their travel behaviour has not yet been analysed thoroughly. In this study we analyse travel satisfaction of 1650 respondents who recently relocated to se...
