ICT and transport behavior: A conceptual review

Information and communication technologies (ICTs) have considerable importance for transport systems, as they provide access to travel information, planning tools, opportunities to share transport modes, to work at-a-distance, compare transport mode cost, make payment, improve safety and health, and to communicate travel patterns. Over the past decade, there has been massive growth in the availability of transportation ICT, in particular, smartphone applications. There is considerable evidence that ICTs have profoundly changed the ways in which transport systems are perceived and used, and mobilities performed, with far-reaching implications for transport mode choices and transport demand. Against this background, the paper seeks to conceptualize ICT with relevance for transport systems, and to discuss the implications for the environmental sustainability of the transport sector. Findings suggest that while some ICT innovations foster and support sustainable transport choices, others raise new and significant barriers to more sustainable transport futures.     

Toward a spatial understanding of active transportation potential among a university population

Universities and surrounding communities stand to benefit when active travel mode choices are elevated. Despite this, there is little research on travel mode choice at commuter universities and, in particular, the nonlinear spatial relationships among active travel potential and various contextual and compositional factors. The purpose of this study was to examine and visualize linkages among personal, household, density, diversity, and design factors, and active travel (bicycling, walking, and mass-transit modes) among a commuter-university population residing throughout southeastern Michigan, USA. This was accomplished by employing exploratory spatial data analysis (ESDA), ordinary least squares (OLS) regression, and a geographically weighted regression (GWR) model. The GWR model outperformed the traditional OLS model in terms of goodness of fit (R² = .534 and R² = .461, respectively). A novel cartographic mapping technique was employed to depict where statistically significant parameter estimates negatively or positively influenced active travel. The main finding was that personal, household, density, diversity, and design estimates varied in both magnitude and spatiality throughout the university's study area. Interestingly, distance was not a universal barrier to active travel potential. These variations emphasize the importance of promoting active transportation through localized interventions as well as coordinating efforts among universities and surrounding communities.     

Disentangling the behavioural side of the first and last mile problem: the role of modality style and the built environment

The first and last mile (FLM) problem, namely the poor connection between trip origins or destination and public transport stations, is a significant obstacle to sustainable transportation as it is likely to encourage the use of cars for FLM travel, if not for the entire trip. This study examines the role of modality style and built environment in FLM mode choice behaviour, in order to identify the key features that might invoke a travel mode shift from cars to more sustainable travel options for both mandatory and discretionary trips. More specifically, this study draws on disaggregate data from the South East Queensland household travel survey and presents a latent class choice model to unravel modality style groups. Results reveal two distinct individual-level modality style groups: (1) driving and walking oriented; (2) multimodal travellers. Individuals in the second modality style group were found to be relatively inelastic to FLM travel time for mandatory trips, while individuals in the first group were largely unaffected by built environment characteristics and highly habitual in their mode choice behaviour for both mandatory and discretionary trips. Home residence environments with high road intersection density and public transport accessibility, and home residence environments with diverse land use mix, respectively encourage individuals within the second modality style to walk for mandatory trips, and discretionary trips. To this end, when place-based policies seek to change certain built environment features, individuals in the second modality style are more likely to shift their preference from cars to more sustainable modes. Finally, our findings have practical planning implications in targeting mode shift through highlighting the importance of considering the intersection of individual modality style in a given locale and mode choice behaviour. More specifically, our findings advocate for place-based policies that seek to target particular locales with the certain modality style deemed to be more predisposed to adopting a mode shift.     

Flashpacking and automobility

Recent research has attempted to distinguish the key differences between backpacking and flashpacking. However, research observing how both groups choose to travel between destinations remains a neglected theme, and one that may also reveal distinct behavioural differences. This paper critically examines the methods of transportation used by backpackers and flashpackers and analyses how both groups value mobility throughout their respective journeys. While both groups have frequently been identified as being highly mobile, few papers have critically examined the significance transportation choices play in enhancing or fulfilling their desired experiences. Despite suggestions that flashpackers possess far greater financial budgets, most studies have assumed that they travel in similar ways to backpackers. In this paper, the importance of automobility, which is deemed to be a combination of autonomous and self-directed movement, is explored in the context of Norway. Using a qualitative methodology, the experiences of 43 interviewees (26 backpackers and 17 flashpackers) at 10 different hostel locations were recorded in 2009. The findings revealed that backpackers and flashpackers exhibited highly contrasting mobilities, and that previous assumptions regarding how they choose to travel should be challenged.     

Sustainable transport challenges in a suburban university: The case of the Autonomous University of Barcelona

This paper provides detailed accounts of the transport patterns at the Autonomous University of Barcelona (UAB), including its motivations, barriers and user preferences, and explores the main transport challenges faced by the UAB campus. This suburban university is an important transport activity generator in the Barcelona Metropolitan Region, which is committed to achieving sustainable transportation. Results have been obtained through a personal survey (n=5525) of members of the university community. These show that the main limitations for changing travel mode from private means to non-motorised or public modes of transport are: the lack of adequate infrastructure, the marginal role of walking and cycling as a means of transport, and the longer time involved using public transport.     

Millennials,built form,and travel insights from a nationwide typology of U.S. neighborhoods

We examine the relationship between the built environment and the travel of Millennials in the United States. We develop a neighborhood typology to characterize the built environment and transportation networks in almost every U.S. census tract, allowing us to identify possible synergistic and/or threshold effects on travel. We measure travel behavior in two ways: (1) using a multi-faceted traveler typology created using latent class analysis, and (2) by measuring the vehicle miles of travel among people in each of these traveler types. This dual approach allows us to distinguish between the built environment changes needed to encourage travel by modes other than driving, and those needed to reduce vehicle miles traveled among drivers. Using a multinomial logistic regression, we find that travel patterns are relatively stable along much of the urban-rural continuum, everything else equal. Driving was substantially lower only in “Old Urban” neighborhoods, where densities, job access, and transit service are dramatically higher than in all other neighborhood types. This finding implies that dramatic changes in the built environment—doubling or even tripling development density or transit service—may do little to get young people out of their cars when initial densities or transit services are low, as they are in most of the U.S. Conversely, reducing vehicle miles traveled among drivers appears to require more modest built form changes, a finding that offers some room for optimism among those concerned with auto dependence.     

TRIBUTE: Trip-based urban transportation emissions model for municipalities

This research aims at developing modeling and scenario-comparison tools to explore the impacts of various transportation and land use planning policies on changing travel behavior and eventually greenhouse gas (GHG) emissions. A Trip-Based Urban Transportation Emissions (TRIBUTE) model is developed. Data required for TRIBUTE comes from household travel surveys and emissions inventories, which is a major advantage in cases where a detailed transportation network model is unavailable. TRIBUTE is composed of two main parts: a mode choice model and an emissions forecasting model. The mode choice model is responsible for estimating modal shares of alternative modes of travel in response to changes in personal, modal, and land use attributes. The emissions forecasting model translates the modal shares into vehicle kilometers traveled, and subsequently GHG emissions. TRIBUTE is a macroscopic model intended to assist municipalities evaluate alternative transportation and land use policy scenarios and eventually select the one(s) that help them meet their future GHG emission targets. This paper reports on the conceptual framework of the developed model and presents a case study.     

What drives sustainable student travel? Mode choice determinants in the Greater Toronto Area

Examination of mode choice behavior is an important step in accurately predicting future travel demand. Despite having somewhat unique travel needs and challenges, there is a lack of knowledge in understanding the mode use behavior of university student population. The existing studies on university populations relied on a relatively smaller sample in investigating the behavior. Therefore, using world's largest university student's travel database, this study examines the factors affecting the mode choice behavior of a diverse university student population with student samples from four universities and their seven campuses located across the Greater Toronto Area (GTA) in Canada. Additionally, stratifying this diverse population using their attitudinal responses towards numerous travel modes, this study also estimates three additional mode choice models to obtain a more comprehensive understanding of how students in different markets, with different latent attitudes towards transportation, vary in terms of sustainable mode choice. A cluster analysis based on fourteen attitudinal responses, was conducted to stratify the sample whereas the popular multinomial logit approach was used to estimate the mode choice models. This study finds transit pass and bike ownership as important determinants that govern sustainable mode choice among the students in the region. The findings of this study could facilitate the sustainability offices at the four universities in making an informed policy decision in shifting the mode use behavior of students towards sustainable modes.     

Same city—different options: An analysis of the work trips of married couples in the metropolitan area of Oslo

The question raised in this paper is in which ways the urban structure interacts with or creates different conditions for activities made by men and women. To explore this question the paper focuses on the travel to work of married couples in an urban context, how they adapt time use and deal with the spatial choices of work places and the allocation of transport resources. The empirical analyses are based on a personal travel study from the Oslo-region in 1990/91. Women work closer to their homes than the husbands, and have less choice on the geographical labour market. In families with one car, the husband has the first choice. Women have more often tasks on the way to and from work related to household responsibilities.     

Conceptualising convenience: Transportation practices and perceptions of inner-urban high density residents in Brisbane,Australia

High-density living in inner-urban areas has been promoted to encourage the use of more sustainable modes of travel to reduce greenhouse gas emissions. However, previous research presents mixed results on the relationship between living in proximity to transport systems and reduced car-dependency. This research examines inner-city residents’ transportation practices and perceptions, via 24 qualitative interviews with residents from high-density dwellings in inner-city Brisbane, Australia. Whilst participants consider public transport accessible and convenient, car use continues to be relied on for many journeys. Transportation choices are justified through complex definitions of convenience containing both utilitarian and psycho-social elements, with three key themes identified: time-efficiency, single versus multi-modal trips, and distance to and purpose of journey, as well as attitudinal, affective and symbolic elements related to transport mode use. Understanding conceptions of transport convenience held by different segments of the transport users market, alongside other factors strongly implicated in travel mode choice, can ensure targeted improvements in sustainable transport service levels and infrastructure as well as information service provision and behavioural change campaigns.     

The influence of personality traits on airport public transport access mode choice: A hybrid latent class choice modeling approach

Many objective and subjective factors affect individual tendencies. Such subjective factors include personality traits, attitudes, identities, perceptions, and feelings. The choice of transportation mode is an individual tendency that is considered important in policy-making decisions, and it can affect sustainable transportation, particularly in metropolitan areas. The present study’s main aim is to determine the impact of the Big Five Personality Factors on individual preferences toward public transportation modes. We use data from a survey conducted in January and February of 2015 at Imam Khomeini International Airport (IKIA). Passengers were asked to indicate their preferred mode of transportation to access the IKIA and to respond to questions on the NEO Five-Factor Inventory. Based on 557 valid responses, hybrid discrete latent class modeling was conducted to understand the heterogeneity in the respondents’ individual preferences regarding the Big Five Personality Factors and their preferences toward public modes of transportation. The results indicated that individuals who display neuroticism were more likely than the others to be concerned about carrying heavy luggage and about inclement weather conditions when using public transportation. In addition, interesting results indicated that conscientious individuals likely paid more attention to travel cost than to any other attribute of public transportation, and the model of the conscientious latent personality trait was a better fit to the data. Finally, this paper examined the taste heterogeneity of each personality trait and the results indicate the usefulness of considering personality traits in mode choice models for richer insights toward sustainable transportation.     

Divergent infrastructure: Uncovering alternative pathways in urban velomobilities

In recent decades, cycling facilities have moved to the forefront of many urban-planning and climate-action initiates. Yet much of the research and policy developments in sustainable transportation are concentrated in high-investment areas, with sparse attention to travel conditions in low-income localities. Drawing from ethnographic methods, this paper explores socio-spatial inequalities and struggles for transportation space within the Mexican bajío. Focusing on the city of Aguascalientes and its outskirts, I explore the implementation of cycling facilities in a context of rapid-freeway expansion, neoliberal restructuring and public-transit divestment. Specifically, this paper analyzes the fragmented implementation of cycling lanes in certain areas of the city, while drawing attention to the experiences of low-income and peri-urban cyclists who operate at the margins of broader motor-vehicle infrastructure. In contexts of widespread spatial exclusions, I suggest that a focus on these commuters' mobility is needed to account for both the planned and inadvertent strategies that they assemble to bypass transportation barriers. What types of temporary bridges, improvised technologies and alternative pathways—what I define as divergent infrastructure—do cyclists configure when standardized systems fail to meet their present needs?     

To drive or not to drive: Driving cessation amongst older adults in rural and small towns in Canada

Driving cessation, often due to health-related changes, can be a particularly challenging and troublesome transition in older adulthood that can lead to social isolation. While policy makers have long recognized the potential impact of an aging population on Canada's health care and national pension plans, the transportation needs of older adults have received relatively less attention. For older adults residing in small towns and rural areas who rely, more often than not, on the personal automobile there is usually limited or no access to public transportation. For policy makers to respond effectively to the transportation needs of an aging population, particularly those living in rural areas, the first step is to understand the travel behaviours of older adults living in such areas, particularly as they approach the transition when they will cease to drive. This paper reports on qualitative research exploring the driving-related challenges and needs faced by older adults in small towns and rural areas near Hamilton, Ontario, Canada. Results revealed four major themes: lack of transportation options in rural areas, changes in driving behaviours, the lack of planning for driving cessation, and the social isolation that comes from the loss (or potential loss) of one's driver's license.     

Spatial and socio-demographic determinants of South East Queensland students’ school cycling

The low prevalence of Australian students’ utilitarian school cycling could be attributed to the varied and context specific demographic, socio-economic and spatial school travel mode choice determinants. Travel distance is universally important for school cycling and is reliant amongst related home and school spatial proximity factors on a student’s choice of schools. This paper, primarily based on school students’ travel data extracted from the 2009 South East Queensland Household Travel Survey (SEQHTS), examines comparative school cycling travel patterns, school catchment choices and the significant analytical determinants of cycling mode choices from within an urban regional Australian context. Students’ choice of a school external to that located within their designated State school catchment zone was associated with household attributes of parent/guardian employment location, number of income earners and ownership of private vehicles coupled with State school and catchment attributes. Noteworthy variations in school travel distances and modal splits were allied with school catchment choices. Adolescent male students from two parent households owning fewer than two cars and more than two bicycles, with parents/guardians commuting using non-motorised travel modes and resident in Census Collection Districts with conducive cycling environments, contributed largely to the one-way bi-directional primary and secondary school cycling mode shares. This prevalent student cyclist profile indicates the need for enhancements in student school cycling participation, through policies addressing both the spatial (built) and social environment which impact students’ personal and traffic safety coupled with utilitarian cycling image enhancements. Concerted efforts to bolster cycling amongst student segments with current low cycling participation inclusive of females, students from single parent households and those with adequate access to private motorised travel modes may be necessary to further enhance school cycling mode shares. The paper makes a case for individualised targeted travel interventions informed by segregated mode choice determinant analysis for respective primary and secondary school types and directions of school travel.     

Travelling to the Ancestral Homelands: The Aspirations and Experiences of a UK Caribbean Community

This paper is based on an ethnographic study of the Caribbean community of Moss Side, Manchester (UK). Its aim is to reveal, interpret and analyse the personal meanings which members of the community attach to visiting the ancestral homeland in the Caribbean. This form of travel is defined in terms of 'ethnic reunion', which involves travelling for the purpose of visiting friends and relatives and/or searching for one's cultural roots. The study, which is based on an interpretive analysis of a range of ethnographic material, initially examines the reasons why first- and second-generation Caribbeans wish to participate in the 'homeland experience', and then illustrates ways in which they reconstruct an identity of themselves through their travel perceptions and experiences. The latter part of the paper discusses how people's travel encounters serve to illustrate how ethnic differences and boundaries between groups are constructed and/or reconstructed. It is argued that established perspectives of tourism motivation and behaviour do not fully account for the role of ethnicity as a significant variable in influencing specific forms of travel. The conclusion asserts that ethnic reunion should be conceptually viewed as a distinct form of 'travel', socioculturally dissimilar to conventional forms of 'tourism'.     

Do rural older adults take fewer trips than their urban counterparts for lack of a ride?

Aging and the presence of one or more illnesses result in limited travel for many adults age 65 and over. Yet, the need to get to essential, social, and non-emergency medical destinations endures. At some point in their life, older adults become dependent on family/friends, or rely on for-profit/not-for-profit transportation services for their mobility needs, while some do not go on certain trips. Researchers have studied out-of-home activity and mobility of older adults using data on trips taken. There is a gap, however, in understanding trips not taken in the older adult population in rural versus urban locations. Our objectives in this paper are: (i) to investigate unmet travel needs of older adults by relying on responses for trips not taken; (ii) to examine how personal abilities, living situation, and socio-demographic factors are associated with trips not taken to various destinations; and (iii) to compare the likelihood of trips not taken due to lack of a ride in urban versus rural locations across the age and income spectrum. Our data come from a phone survey conducted across the province of Alberta, Canada, in 2017–18 (n = 1390). We specify ordinal logistic models where the dependent variable is how often a respondent did not undertake a trip due to not having a ride to various trip destinations. We find that rural seniors are more likely to not take trips compared to older adults in cities, holding all else equal including driving cessation, worsening health, and disability. Rural seniors who live alone or in low-density housing are also more likely to not take trips compared to urban older adults. Household income, however, tempers these location preferences. Our findings suggest that rural older adults can be supported through income transfers, community-based low-cost travel, and moving to higher-density residential locations.     

Assessing preferences for mega sports event travel products: a choice experimental approach

Hosting mega sports events spreads positive destination images and generates massive tourism arrivals for the host communities. It is, therefore, important for tourism businesses to better understand what types of travel products, tailored for particular mega sports events, are purchased by sport tourists. Using a choice experimental approach, this study aims to examine how sport tourists formulate their preferences for travel products customized for the 2018 PyeongChang Winter Olympic Games by making intricate trade-offs among various product attributes. We utilize a gender perspective to further understand the preference dynamics embedded in segmented sport tourism markets. Study results suggest that sport tourists put distinctive weights on each of the attributes comprising the Olympic travel products. Gender differences are also identified in sport tourists’ choice decisions for sports event travel products. Based on the study findings, this paper proposes several marketing strategies to meet the needs of targeted market segments.     

Employment centers and travel behavior: exploring the work commute of Mumbai’s rapidly motorizing middle class

In the Greater Mumbai Region (GMR), jobs and housing are agglomerating in nodes in the periphery of Mumbai City. However, current transportation investments focus on strengthening connections within Mumbai City, while these outlying nodes have received less attention. As housing and jobs move out, given limited travel choices, the need for mobility nudges many middle class Indian households into owning private vehicles. Using household travel survey data from the GMR, this paper develops an understanding of how worker’s trips are different for those who commute to the city versus the exurbs. Socio-economic and transportation indicators for middle class workers going to the city versus the exurbs show that these populations are quite similar demographically. However, those traveling to the exurbs, on average, tend to be at a socio-economic disadvantage with respect to income, education and out-of-pocket travel burdens. Those traveling to exurban work locations have shorter travel times and trip distances, and make much higher use of walking, biking, rickshaws, and motorized two-wheelers compared to commuters to Mumbai City. Across the GMR, car users travel longer and farther compared to motorized two-wheeler users. On average, traveling by a private vehicle is faster than bus or rickshaw travel revealing advantages of private vehicle use. These mode choices in the middle class have resulted in rapid motorization and negative externalities such as traffic congestion and emissions. Evidence of large increases in motorized two-wheelers and cars in India suggests that these modes will likely keep growing, unless competing efficient travel options are supplied.     

Local stakeholders,role and tourism development

Building sustainable communities, as well as sustainable forms of livelihood, including tourism, has been a key objective among many government agencies and community stakeholders. Against this background, and through the lens of role theory, the present study investigates the potential for sustainable tourism to be developed in a rural community. Data were gathered among business owners and residents of Bridgetown, Western Australia. Four key groups of participants emerged, each emphasizing participants' role as community, and therefore, as tourism stakeholders. Alignment with various perspectives of role theory, including functional, “symbolic interactionist”, structural and cognitive was noticed; similarly, consensus, conformity and role taking were identified as key concepts. Whether currently involved in tourism or not, participants' pro-active role suggesting practical ways to enhance the sustainability of local tourism could be a powerful tool in this and other communities seeking to build their destination image.     

‘Mobility work’: Older adults' experiences using public transportation

This paper contributes to research on public transport accessibility, disabling spaces, and older adult's mobility by highlighting the ‘mobility work’ older adults complete to meet their daily travel needs. Drawing on a systematic and inductive analysis of semi-structured interviews with older adult (65+ years of age) public transit users in Hamilton, Canada, we argue that older adults are faced with mobility work that younger and/or more able-bodied people do not routinely encounter as they meet (or attempt to meet) their daily travel needs using public transportation. Key components of older adults' trips that involve mobility work include walking to and from the bus stop, trip planning, stepping onto/ off of the bus, finding a seat, carrying items on the bus, calling a stop, and travelling in winter conditions. This mobility work can be categorized as physical (e.g., struggling to board the bus), emotional (e.g., worrying about getting a seat), or spatiotemporal (e.g., staying home when the weather is bad). Taken together, this paper puts forward a multidimensional concept of ‘mobility work’ to aid in considering accessibility at the scale of both the individual and the built environment. Further, by highlighting mobility work, this paper demonstrates the ways in which public transport spaces can be disabling for aging bodies and outlines concrete measures public transit agencies can take to make services more accessible to older adult riders.
