Identity and travel behaviour: A cross-sectional study on commute mode choice and intention to change

IntroductionSocial and self-identities have been conceptualised to prevent travel behaviour change, as threats to one’s identity may cause resistance to change. This study focuses on the role of social, transport, place, and self-identities on commute mode choice and intention to change mode choice.MethodData were collected in June 2015 in Utrecht, the Netherlands. Invitations to participate were distributed by mail using data from the municipality, resulting in 1062 adult participants.The outcome measures were the transport mode shares based on a 14-day travel-to-and-from-work record of trips (i) involving any car use, (ii) involving any bicycling, (iii) involving any walking, and (iv) involving any public transport use. The second series of outcome measures concerned the willingness to change the amount of car use, bicycle use and walking, determined by the question ‘to what extent do you intend to change the use of …?’. Identity was measured on a seven-point disagree/agree scale for 17 items by asking to what extent the respondent ‘sees him/herself as …’. Separate multinomial regression models were estimated stepwise adjusting for socioeconomic and transport characteristics.ResultsMultiple identity items were associated with the use of all commute modes. In the maximally adjusted models, identities associated with the respective modes remained significant. For example, whether someone identified themselves with being a cyclist corresponded with higher likelihood of cycling occasionally (relative risk ratio (RRR): 1.84; 95% confidence interval (CI):1.47–2.30), or always to work (RRR: 2.86; 95% CI: 2.16–3.79). In addition, we found that a family-oriented identity was negatively associated with occasional commuting by car, and a ‘sporty’ identity was negatively associated with always cycling to work.Transport identities were also associated with stated intentions to change as were several social, place, and self-identities. Identifying with being a car driver decreased the likelihood of intending to reduce car use, but it increased the likelihood of intending to increase car use, as did identifying with being career-oriented. Individuals that identified with being a cyclist were less likely to have an intention to reduce bicycle use, whereas countryside-lovers had greater intentions of increasing cycling. Individuals that identified themselves as pedestrians had a lower intention of decreasing their walking levels, and a higher intention of increasing them, as did those who identified themselves as being family-oriented.DiscussionThe results confirm limited previous findings that identifying with users of a transport mode correspond with its use. Nevertheless, questions around causality remain. The intention to change mode choice was associated with several identities, including transport-related identities, place-related identities, social/family-related identities, and self-identities. Future research should focus on the associations between identity and actual behaviour change to further our understanding of the effect of identity on travel behaviour.     

Accuracy of household planning of car use: comparing prospective to actual car logs

Measures aiming at changing car use are frequently based on the assumption that car use is under motivational and volitional control. The aim of this study is to investigate the degree to which this is the case and how it relates to different purposes of car trips and characteristics of car users. Data obtained from 1-week prospective car logs made by 40 adult households living in Göteborg, Sweden, were compared to subsequent actual car use. In line with previous results suggesting that households have a modest degree of motivational and volitional control over their car use, it was found that 80% more car trips were made the following seven days than indicated in the prospective car logs. The largest discrepancies were observed for shopping and chauffeuring trips, the least discrepancy for work trips. Households having more than one car made more shopping trips than planned, households with children more chauffeuring trips than planned, and households with a higher income more leisure trips than planned. Weather conditions, illnesses, mode switches, and unspecified unexpected events were reported as reasons for the discrepancies between planned and actual trips.     

How do public transport users adjust their travel behaviour if public transport ceases? A qualitative study

Mode shift from public transport (PT) to private car when a PT shut-down occurs results in an increase in the number of car trips on the road network which may contribute to traffic congestion. Policies aimed at reducing the mode shift to car can be designed through a better understanding of PT users’ mode shift in the event of a PT disruption. Furthermore, the share of car mode shift is also an important parameter for assessing traffic congestion relief associated with day to day PT provision in cities. This study sought to uncover factors influencing the mode shift to car among PT users in the event of a PT disruption. Semi-structured interviews were conducted with 30PT users from Melbourne, Australia. Grounded theory was used to derive categories and subcategories of behavioural responses. Factors affecting mode shift to car if PT ceases in the short term were classified into three main themes with several subcategories: individual-specific factors, context-specific factors and journey-specific factors. In the long term, the analysis reveals that only context-specific factors have an influence on mode shift. Findings show that car access, travel time, travel cost, trip importance, non-central business district (CBD) trips, weather, flexibility and accessibility to PT stations are the most important factors favouring use of the car if PT ceases in the short term. This acts to increase traffic congestion due to the mode shift to car. However, in the long term, removing PT is expected to have an impact on land use, leading to individuals changing their residential and workplace location.     

How satisfying is the Scale for Travel Satisfaction?

The Satisfaction with Travel Scale (STS) has recently been developed to measure people’s satisfaction with travel. It supposedly consists of two affective and one cognitive dimension. As there have only been a few tests of its reliability and structure to date, this paper reports new tests using data on leisure trips from Ghent (Belgium). Differences in the reliability and structure of the STS by transport mode – car, public transport, bicycling and walking – are also considered. Overall, the results suggest that the specification of a single underlying dimension for affect rather than two offers a superior fit to the Ghent data, both for all modes combined and for car use and cycling separately. For public transport and walking a three-dimensional structure is more appropriate although individuals items do not load on the two affective dimensions as expected. Differences between previous studies and ours are partly caused by differences in how two of the scale’s items – alert/tired and confident/worried – are correlated with the other items. Future studies using the STS may want to adapt the structure of STS by omitting some items or replacing them with alternatives as this may reduce respondent burden and increase internal consistency of the STS.     

Am stressed,must travel: The relationship between mode choice and commuting stress

The stress of commuting has serious public health and social implications. By comparing stress across different modes it is possible to determine which modes are more heavily contributing to this potential health and social issue. This study uses a large-scale university travel survey to compare commuter stress across three modes of transportation (walking, driving, and using public transit). It also investigates the specific factors that contribute to stress using these modes. Using ordered logistic regressions, the study develops a general model of stress and three mode-specific models. Results show that driving is the most stressful mode of transportation when compared to others. We also find that stressors for some modes are not stressors for others. Knowing which specific factors make certain modes stressful will help transportation and public health professionals make commuting a safer, more enjoyable, and less stressful activity; in turn this could mitigate the potentially serious health outcomes of a stressful commute.     

Why would people want to travel more with automated cars?

The use of automated vehicles (AVs) may enable drivers to focus on non-driving related activities while travelling and reduce the unwanted efforts of the driving task. This is expected to make using a car more attractive, or at least less unpleasant compared to manually driven vehicles. Consequently, the number and length of car trips may increase. The aim of this study was to identify the main contributors to travelling more by AV.We analysed the L3Pilot project’s pilot site questionnaire data from 359 respondents who had ridden in a conditionally automated car (SAE level 3) either as a driver or as a passenger. The questionnaire queried the respondents’ user experience with the automated driving function, current barriers of travelling by car, previous experience with advanced driving assistance systems, and general priorities in travelling. The answers to these questions were used to predict willingness to travel more or longer trips by AV, and to use AVs on currently undertaken trips. The most predictive subset of variables was identified using Bayesian cumulative ordinal regression with a shrinkage prior (regularised horseshoe).The current study found that conditionally automated cars have a substantial potential to increase travelling by car once they become available. Willingness to perform leisure activities during automated driving, experienced usefulness of the system, and unmet travel needs, which AVs could address by making travelling easier, were the main contributors to expecting to travel more by AV. For using AVs on current trips, leisure activities, trust in AVs, satisfaction with the system, and traffic jams as barriers to current car use were important contributors. In other words, perceived usefulness motivated travelling more by AV and using AVs on current trips, but also other factors were important for using them on current trips. This suggests that one way to limit the growth of traffic with private AVs could be to address currently unmet travel needs with alternative, more sustainable travel modes.     

Cycle commuting intention: A model based on theory of planned behaviour and social identity

Although cycling as a mode of transport can provide various important benefits to cities and their transport systems, it accounts for only a small proportion of commuter trips in southern Europe. The aim of this study was to develop a new model based on Ajzen’s (1991) theory of planned behaviour (TPB), but including social identity as an additional predictor variable to improve the explanatory capability of the TPB. We conducted a telephone survey of a representative sample of 595 non-cycle commuters in the Spanish city of Vitoria-Gasteiz, which has a moderate proportion of bicycle users (6.9%). Confirmatory factor analysis to test the model showed satisfactory overall measurement fit, and all sub-scales had high reliability and validity coefficients. The findings demonstrated the value of incorporating social identity into the TPB to capture motivational factors relevant to cycle commuting. The relationships between the factors in the model indicated that there is a strong link between identifying as ‘a cyclist’ and perceived self-efficacy with respect to cycling. Furthermore, the results suggest that a more specific measure of perceived self-efficacy, targeting concrete behaviours could be used to inform development of initiatives to promote urban cycling. Our data also revealed that, excluding control variables such as journey time, economic cost and distance, the psychosocial variables included in the model predicted 32% of the variance in car users’ intention to start commuting by bicycle.     

Walkability,risk perception and safety assessment among urban college pedestrians in Kuwait

The aim of this study was to examine what factors worried people as pedestrians in Kuwait. It aimed also to assess the correlation between perceived risk and worry and between worry and walking frequencies. The focus of this study was on urban college pedestrians as one of the most vulnerable population groups that suffered recently from many safety problems related to walking activities. This is relevant since most of the college’s students in Kuwait University are female (almost 90%). To do so, an online questionnaire was conducted to assess how respondents perceived risk and how worried they were when exposed to different hazards (traffic accident, harassment, and theft). Another online questionnaire was used to calculate the walkability index at different areas of Kuwait. From the results, it was shown that worry had influenced the pedestrian’s behavior as walking frequencies had dropped among respondents who had higher levels of worry. Cohen’s d showed a large difference in worry levels between those who walk daily and those who rarely walk. People reporting high levels of worry from experiencing accidents, harassment, and theft during nighttime were around 15 to 20% higher than those during daytime. The results from the second questionnaire showed that the area with the highest walkability index was Sabah Al-Salem as it was rated as the safest, the highest density of interesting businesses, and the best public transit area. These observations showed that major improvements are needed in Kuwait to increase the modal shift from cars to walking. In order to induce healthier lifestyles and improve the pro-environment by reducing the emissions linked to car usage.     

Barriers to children’s walking to school in Iranian and Chinese samples

Factors that contribute to children’s walking to school have been investigated in previous research, which primarily focussed on socio-economic variables in high income countries. There is a general lack of studies which have examined mode choice differences on school trips in low and middle income countries. Focusing on parental social cognitive variables in addition to household socio-economic characteristics, the present study is among the first to compare barriers to children’s walking in daily commuting to schools across samples from two middle income countries: Iran and China. A self-administered questionnaire was devised and distributed among primary school pupils (7–9 years old) in Mashhad, Iran and Nanjing, China. The children were asked to take the questionnaires to their parents to complete and return the filled forms. A total of 671 (response rate of 90 percent) and 224 (response rate of 82 percent) completely filled questionnaires were returned in Mashhad and Nanjing, respectively. Multivariate analysis of covariance (MANCOVA) showed that parents in Mashhad perceived higher risk and reported more worry of children being involved in road crashes when walking to school. Analyses revealed more safety favourable parental attitudes in the Chinese sample, compared to the Iranian sample. Parental attitudes towards transport safety were safer in the sample from Nanjing as compared to Mashhad. Hierarchical binary logistic regression showed that walking time from home to school and parental worry about road crashes were negatively associated with children’s walking to school in both samples. In the Iranian sample, results suggested that while household car ownership and higher family income were associated with a decreased probability that a child walk to school, the total number of children in the household increased the probability of walking to school.     

Differences in parental perceptions of walking and cycling to high school according to distance

BackgroundParental perceptions towards different modes of transport correlate with adolescents’ mode choice for school trips. Whether parental attitudes differ for walking versus cycling and/or home-to-school distance is unknown. We compared parental perceptions of walking versus cycling to school in adolescents in Dunedin, New Zealand and examined whether mode-specific barriers differ by distance to school.MethodsParents (n = 341; age: 47.5 ± 5.2 years; 77.1% females) completed a survey about their adolescent’s (age: 13–18 years; 48.1% boys) school travel and their own perceptions of walking/cycling to school. Participants were categorised into three groups according to distance to school as ‘walkable’ (≤2.25 km), ‘cyclable’ (>2.25–≤4.0 km) and ‘beyond cyclable’ (>4.0 km).ResultsCommon modes of transport to school differed significantly across the ‘walkable’/’cyclable’/’beyond cyclable’ categories (car passenger: 25.7%/40.5%/60.6%; public/school bus: 5.5%/15.4%/28.4%; walking: 66.2%/28.2%/1.2%; cycling: 0.0%/7.7%/0.5%; all p < 0.001). Compared to walking, parents perceived cycling to school to be less important (walking/cycling: 87.5%/62.5%), with less social support from parents (46.2%/17.1%), peers (20.6%/4.8%) and school (24.5%/12.4%), less interest from adolescents (48.5%/31.9%), fewer cycle paths (26.5%) versus footpaths (65.0%) and more safety concerns (35.0%/64.6%; all p < 0.001). As distance to school increased, parents’ social support decreased whereas personal, environmental and safety-related barriers increased for both modes, with less consistent findings for cycling. Overall, 68.2% of parents expected to participate in adolescents’ walking/cycling to school decision-making.ConclusionsParents favoured walking compared to cycling to school with parental attitudes for both modes changing with increasing distance to school. The findings illustrate the importance of addressing parental concerns, considering the specificity of walking and cycling and taking into account distance to school in active transport to school initiatives.     

Would you rather teleport or spend some time commuting? Investigating individuals’ teleportation preferences

The “teleportation test” is a unique question—used in some travel behavior research since the 2000s—to examine individuals’ perceptions towards travel time and affinities for travel. It gives people a hypothetical choice between teleporting or spending some time traveling. All studies (using different methods, including focus groups, interviews, and questionnaires) have consistently reported high teleportation preferences (about 70%). Yet, few correlates of teleportation preferences (especially sociodemographic and perceptual characteristics) have been investigated. Using data from an online questionnaire of 648 commuters in Portland, Oregon, this study investigated factors affecting individuals’ teleportation preferences. While generally representative of the area’s commuters, the sample did have higher shares of high-income workers and people using active modes or transit. Overall, 62% of respondents preferred to teleport than to spend some time commuting. Results from binary logit models identified actual commute duration, typical mode of travel, and “ideal” travel time (but no demographic attributes) as major predictors of preferences to teleport. As expected, people with longer commute durations had a greater desire to teleport, whereas bicyclists and pedestrians more often preferred to commute. People with longer ideal travel times had a greater affinity to commute and were less keen to teleport. Analysis of follow-up questions exploring reasons for respondents’ answers suggested that most “teleporters” were motivated by saving time to do other things, while most “commuters” found parts of their commutes to be enjoyable or productive. Findings from this study are consistent with related studies in implying that a teleportation preference does not necessarily represent zero ideal travel time or viewing travel time as wasted. Finally, this study discusses several travel behavior policy implications of the teleportation test, along with limitations and areas for future research.     

An interdependence analysis of commuting decisions

The current research advances an interdependence analysis of commuting decisions (i.e. commuting by car versus public transportation), delineating the determinants of an individual's outcomes in terms of own decisions, other commuters' decisions, and the combination or interaction of own and others' decisions (Kelley & Thibaut, 1978). Consistent with hypotheses, findings revealed that a concern with comfort led to a higher overall personal preference for the car, and a lower overall preference for others to commute by public transportation, when compared to a concern with travel time. Additionally, consistent with the claim that commuter decisions are also guided by considerations broader than a concern with individual outcomes, findings revealed that individuals with prosocial orientations (i.e. those concerned with maximizing collective outcomes) in combination with high levels of trust (i.e. believing in the honesty and cooperative intentions of others) exhibited a greater overall personal preference for public transportation, and a reduced desire to avoid other commuters, relative to individuals with a prosocial orientation and low levels of trust, or a proself orientation (i.e. those concerned primarily with maximizing own outcomes), regardless of levels of trust. Finally, consistent with the current interdependence analysis, intention to commute by car was positively associated with not only overall personal preference for the car, but also with the desire to avoid other commuters. © 1997 John Wiley & Sons, Ltd.     

Users of different travel modes differ in journey satisfaction and habit strength but not environmental worldviews: A large-scale survey of drivers,walkers, bicyclists and bus users commuting to a UK university

People who travel to the same university workplace by bicycle, bus, car, and walking were compared in a survey (N = 1609). Data are presented on environmental worldviews, journey affective appraisals, and habit strength. Unexpectedly, findings showed comparable levels of environmental worldview across modes. This might reflect the role of attitudes on behaviour, or question the validity of the established environmental worldview scale used here. Results also replicated previous work on affective appraisal, and suggested that whilst walking, bicycling and bus use have distinctive affective appraisals associated with each mode, car driving was affectively neutral, generating no strong response on any dimension – a finding tentatively explained with reference to the normative status of driving. The survey also showed users of active travel modes reported stronger habit strength than car or public transport users, with possible links to the role of affect in formulating habit strength in line with habit theory.     

Women's Future Travel, Driving, and Transit Use

Women's future community travel needs have not yet been analyzed to determine how changes in society will affect or be affected by women's car driving and public transit use. The author infers from limited available data that automobiles will accommodate more of women's travel needs because transit might not satisfy many trip requirements, including those for mental well-being and personal security and for continued homemaking and childrearing responsibilities. Insensitive government restrictions on women's auto use should be discouraged; positive investment and management strategies for automobile and transit systems should be encouraged to help women travelers. Research, employment efforts, and increased public input within the transportation industry are among the recommended long term strategies to improve industry and public awareness and to foster constructive actions on the behalf of women.     

Mobility as a service and sustainable travel behaviour: A thematic analysis study

Mobility as a Service (MaaS) is a novel brand of transport that promises to replace private cars with multimodal personalised mobility packages enabled by a digital platform capable of integrating travel planning, booking and ticketing, and real-time information services. It is an intervention that through its digitisation, connectivity, information and sharing merits intends to inspire and support the transition to a more sustainable mobility paradigm. Recent research suggests, however, that the potential uptake of MaaS might not be overwhelming; current car drivers could face considerable difficulties in bypassing their personal car for it and, more worryingly, future MaaS users may substitute not only personal car trips but also public transport journeys with car-sharing and ride-sharing services. This means that MaaS might not be able to create travel behaviour change, and even if it does, the changes may not be always towards the right direction. Through conducting 40 semi-structured interviews in three different UK cities, namely London, Birmingham and Huddersfield, and employing a robust Thematic Analysis approach, this study explores the factors underpinning the uptake and potential success of MaaS as a sustainable travel mechanism. The challenges and opportunities reflecting and affecting potential for responsible MaaS usage refer to five core themes Car Dependence; Trust; Human Element Externalities; Value; and Cost, each of them with distinctive and diverse dimensions. Policy-makers and mobility providers should realise that MaaS success relies on changing people’s attitudes to private cars (something very challenging) and thus they should incentivise responsible MaaS use, promote public transport as its backbone, use public engagement exercises and trials to expose people to the concept and somewhat demonise private car ownership and car use.     

On time and ready to go: An analysis of commuters’ punctuality and energy levels at work or school

The strain of the daily commute can negatively impact performance at work. This study differentiates how various modes influence commuters’ punctuality and energy levels at work and school. The data for this study come from the 2013 McGill Commuter Survey, a university-wide survey in which students, staff and faculty described their typical commuting experience to McGill University, located in Montreal, Canada. Ten multilevel mixed-effects logistic regressions are used to determine the factors that impact (1) a commuter’s feeling of being energized when he or she arrives at work or school and (2) his or her punctuality. Our results show that weather conditions and mode of transportation have significant impacts on an individual’s energy at work and punctuality. The models indicate that drivers have the lowest odds of feeling energized and the highest odds of arriving late for work. Cyclists, meanwhile, have the highest odds of feeling energized and being punctual. Overall, this study provides evidence that satisfaction with travel mode is associated with higher odds of feeling energized and being punctual. With these findings in mind, policy makers should consider developing strategies that aim to increase the mode satisfaction of commuters. Encouraging the habit of commuting by bicycle may also lead to improved performance at work or school.     

Active school travel,attitudes and psychological well-being of children

The decline in physical activity levels among children emphasizes a need for research on experiences related to children’s active travel. The present study investigates the relationship between mode use on school trips and psychological well-being (PWB) of children. Data were collected from 152 primary school children in Lower Austria. The paper-and-pencil survey investigated transport-related attitudes, travel behavior, and children’s emotional well-being depending on the travel mode used on their trip to school. Parents’ perceptions of their child’s travel mode on well-being were also collected in 31 in-depth interviews. Findings suggest that active school travel is positively associated with children’s PWB, and that travel-related attitudes towards modes are significantly related to well-being. However, it is difficult to determine the causal direction between the two variables as causal feedback loops can be assumed. Clear results can be obtained for the parental survey: Parents reported strong positive associations between active travel modes and the well-being of their children. More research with bigger sample sizes and higher quality measures should be conducted, including about non-school trips and with longitudinal datasets, to further evaluate the interrelations between children’s mode use, attitudes, and well-being and to determine the most successful strategies for increasing active mobility among children.
