Travel behavior adaptations resulting from international temporary relocation is understudied, despite their increasing relevance. The scarce published literature on the subject overlooks the local contexts and ignores aspects related to the adaptation processes and motivations. This study aims to partially fill this gap by addressing the travel behavior adaptation of international students and researchers, focusing on public transport (PT) frequency of use and satisfaction. To investigate this, a Bayesian Structural Equation Model was estimated using data collected from a tailor-made online survey answered by temporary international exchange students and researchers. The model confirms that (i) travel behavior habit in the city of origin influences the residential location choice in the host city; (ii) the higher the frequency of PT use in the city of origin, the higher the PT use in the host city; (iii) the residential location in the host city affects individuals’ frequency of PT use and satisfaction; (iv) perceiving technology as helpful to move around leads to perceiving the PT system as easier to use at the beginning of the stay; (v) perceiving the PT as easier to use, leads to a higher frequency of its use and a higher level of satisfaction with the PT system.

Commercial classification is essential to describe and compare the spatial patterns of commercial activity. Most classification systems consider a large set of dimensions that include detailed features such as store ownership or development type. Since new business models are continually being developed, the need to revise classification systems is constant. This makes generalisation hard, thus hindering the comparison of commercial structures in different places and periods. Recent studies have focused on cluster analysis and a smaller number of variables to gain insights into commercial structures, directly addressing this issue. Systematic bottom-up classification generates comparable structures, which is essential to contrast policy results in different situations. Furthermore, since form or accessibility are usually considered in classifications, cluster membership is precluded from most retail location models, often relying on the latter as an explanatory variable. Hence, a new classification system is proposed, based on cluster analysis (k-means) and a minimal set of variables: density, diversity, and clustering. This classification was implemented in 1995, 2002, and 2010 in Lisbon. Cross-sectional analysis of the commercial structures shows the system accurately describes commercial location and change, suggesting it can be generalised as a classification system. Since the minimal dataset also allows for cluster membership to be used on location models, the relationship between commercial classification and location modelling could be strengthened, reinforcing the role of commercial studies in urban planning and policymaking.

In recent years, persuasive interventions delivered through mobility-management tools have received attention as a means to motivate change for sustainable urban mobility. This paper aims to pinpoint and understand the drivers that influence individuals’ travel decisions when using travel apps including both travel information and persuasive features. The analytical framework relies on Lindenberg’s goal-framing theory in which individuals’ motives for using travel apps are grouped into three overarching goals, namely (1) gain, (2) hedonic and (3) normative goal-frames. Furthermore, technophile attitude, community trust and place attachment are incorporated into the framework in order to better explain user-sided heterogeneity. The case-study focuses on the travel information system under development in Copenhagen (Denmark). It questions 822 Danish travelers by distributing a technology-use preference survey. Structural equation models revealed that the choice motivators are specific to individual users and depend on wide ranging factors that go beyond traditional economic and socio-demographic methods. The study reveals: (i) trip efficiency improvement, enjoyment, social interaction and environmentally-friendly travel promotion are important motives for using the new app; (ii) individuals have different intentions according to the perceived value of the new information system as well as travel purposes; (iii) technophile attitude exerts a positive influence on both user motives and use intention; (iv) social and institutional trust in addition to an affective bond to the city influence the use intention of the travel app.

The increasing complexity and demand of transport services strains transportation systems especially in urban areas with limited possibilities for building new infrastructure. The solution to this challenge requires changes of travel behavior. One of the proposed means to induce such change is multimodal travel apps. However, understanding the motivators underlying individuals’ travel intentions is essential to design and evaluate their effectiveness. This paper pinpoints and analyses the drivers and barriers that influence individual travel decisions when using such apps. The analytical framework relies on Alderfer's ERG model of human needs that relate the individual’s intentions to three domains, namely (1) Existence, (2) Relatedness and (3) Growth needs. Furthermore, environmental attitude, information privacy concerns and perceived difficulties when using the system are incorporated as to better explain user-sided heterogeneity. The case-study focuses on a new travel information system in Copenhagen (Denmark), which is not yet operational, through a technology-use preference survey among 828 travelers. Structural equation models revealed that the motivation for choices are specific to individual users and depend on wide-ranging factors that go beyond traditional economic and socio-demographic methods. The study revealed (1) different intentions among individuals according to the perceived value of the new information system, (2) a relation between different environmental attitude constructs and users’ needs, (3) a stronger appeal to use the system for individuals with higher needs of developing social self-concept and eco-travel self-efficacy as well as with lower perceived privacy risk and perceived difficulties, (4) that both functional and psychological factors affect adoption intention.

The initial enthusiasm for home-based telework as an attractive travel demand management strategy has been countered by recent research pointing to its inductive effects on travel. This paper develops path analysis models for one- and two-worker households in Great Britain, using data from the National Travel Survey (2005–2012), to study the effects of teleworking frequency on household-level weekly trips and travel distances by mode. The results indicate that among single-worker households, higher teleworking frequencies are associated with more travel by all modes, particularly by car, while there is no significant association for two-worker households. In terms of policy implications, these results do not support the expectation that home-based telework reduces travel, although the methods used do not permit us to definitively conclude that it increases travel.

We test the effect of different contextualization, scaling, framing and formatting of environmental impacts and health benefits information on commuting mode choice. For this, a stated preference (SP) survey was designed. To also test survey mode effect, the survey was administrated both online and face-to-face. We find statistical differences across the two samples in terms of transport preferences, attitudes and perceptions towards the environment, health and social norms. These could be attributed both to differences in the levels of education and professional occupation and self-selection bias. The results in the models estimated from the SP hint the existence of irrational answers in the web-based sample. Information about global CO2 emissions appears to be ineffective in influencing mode choice whereas self-centric information about calories consumption is effective.

Understanding the link between mode choice and travel satisfaction is essential for promoting sustainable travel by expanding utility theory to include also the eudaimonic value of travel. The study focuses on the hypothesis that more then it’s functional value of arriving from A to B, mode choice creates travel experiences that answer high-order needs such as relatedness, autonomy and competence. This study enhances the framework for representing travel mode choice by incorporating the model of human needs as the missing link between mode choice and travel satisfaction. By developing and analysing a large-scale survey from the Greater Copenhagen Area in Denmark, this study empirically proves that commuting mode choice relates to travel satisfaction by answering functional, relatedness and growth needs. The Greater Copenhagen area represents a region where transit, bicycle and car each have large modal shares, hence enabling to validate the approach in a multi-modal environment. Higher bicycle satisfaction relates positively to cycling self-concepts and self-efficacy and negatively to car self-concepts. Greater car use satisfaction increases with car self-concepts and transit use difficulties, and decreases with functional difficulties in car use and better cycling self-efficacy. Higher transit satisfaction mainly relates to experiencing difficulties with other modes. These insights can be used when formulating transport policies and prioritising resources aimed at achieving sustainable mobility patterns.

This work studies the relationships between the number of complex tours (with one or more intermediate stops) and simple home-based tours, total distances traveled by mode, and land-use patterns both at the residence and at the workplace using path analysis. The model includes commuting distance, car ownership and motorcycle ownership, which are intermediate variables in the relationship between land use, tour complexity and distances traveled by mode. The dataset used here was collected in a region comprising four municipalities located in the north of Portugal that are made up of urban areas, their sprawling suburbs, and surrounding rural hinterland. The results confirm the association between complex tours and higher levels of car use. Land-use patterns significantly affect travelled distances by mode either directly and indirectly via the influence of longer-term decisions like vehicle ownership and commuting distance. The results obtained highlight the role of socioeconomic variables in influencing tour complexity; in particular, households with children, household income, and workers with a college degree tend to do more complex tours. Land-use patterns mediate the effects of tour complexity on the kilometers travelled by different modes. Increasing densities in central areas, and particularly the concentration of jobs, have relevant benefits by reducing car kilometers driven.

This work analyzes the effects of home-based teleworking on the number of trips and weekly miles travelled by mode and purpose for one-worker households in Great Britain using data from the National Travel Survey for the period between 2005 and 2012. Two path analysis models are developed, one considering weekly trips and travel distances by mode and the other weekly trips and travel distances by purpose. Both models consider teleworking frequency in the context of home and workplace land-use characteristics, commuting distance, car ownership levels and weekly trips and travel distances. This framework allows us to explicitly model endogenous relations in the chains of decisions relating these variables. The results suggest that home-based teleworking is a strategy used by people to cope with long and costly commutes. Workers living in less transit accessible areas and with longer commutes tend to work from home more frequently. The main conclusions relating to teleworking frequency point to the fact that it increases weekly miles travelled, particularly by car, while it does not reduce commuting distances travelled. These results suggest that home-based teleworking is not an effective travel demand management strategy, particularly because it seems to increase car use. The overall main result is that teleworkers travel more by more polluting transport modes.

The importance of social networks in counteracting mobility limitations is often overlooked despite allowing individuals to remain included under otherwise adverse conditions. Living in poor accessibility areas and having low mobility is associated with a higher risk for social exclusion; that is, the ability to participate fully in society. In order to explore how social network support can compensate for reduced accessibility and mobility, thus reducing the propensity for exclusion, a survey methodology to collect social network, mobility and accessibility data was defined. The paper presents an overview of the methodology. It includes several subjective scales, a trip diary and several SNA tools to measure the density, interconnectivity and supportive nature of individualś personal networks. Some of the key difficulties encountered and lessons learned are presented along with descriptive statistics of the sample and an illustration of the data collected. This paper attempts to assert the importance of considering, studying and measuring the social aspects of accessibility and mobility, when planning for urban transport systems and presents one possible survey methodology that incorporates the different dimensions of social exclusion in a single survey.
