Validating an older adult driving behaviour model with structural equation modelling and confirmatory factor analysis

The Multilevel Older Persons Transportation and Road Safety (MOTRS) model postulates a role for demographic, functional, and psychosocial factors in driving self-regulation. This study formally tested the constructs of the MOTRS model, and its ability to account for variation in older adult’s driving self-regulation. Four exogenous constructs dealing with sociodemographic and driving-related variables (driving space, dependency on other drivers, health, and driving performance) and three endogenous constructs of psychosocial appraisals (driving confidence, attitudes and beliefs towards driving) were used to predict driving self-regulation. A sample of 277 Australian drivers, aged 65 years or over, completed standardised questionnaires to assess these variables. Structural equation modelling was used to evaluate one of the model’s assumptions. Findings established that sociodemographic and driving-related factors influence older adults’ driving self-regulation by impacting psychosocial variables. A re-specified model accounted for 75% of the variance in self-reported driving self-regulation. When other variables were considered, attitude towards driving was the strongest single predictor of driving self-regulation. These findings provide an initial partial validation of the MOTRS model. The results indicate that psychosocial variables are important determinants of driving self-regulation by older adults. This model could guide future research into older adults’ driving self-regulation.     

The emotional geographies of education: Beginning a conversation

While emotional geography is a burgeoning field of inquiry, to our knowledge no emotional geographies of education exist. Educational research on space and place largely ignores emotionality. In this special issue we begin to rectify this situation through the development of what we call socio-cultural-spatial analyses of education and emotion.     

From workplace attachment to commuter satisfaction before and after a workplace relocation

While attention has been paid to travel satisfaction studies during the last decade, less research has investigated the relationship between the influence of a sense of place – and more particularly the psycho-environmental concepts of workplace attachment and workplace satisfaction – and commuting satisfaction. Using a retrospective survey, this paper focuses on the relocation of a workplace within the city of Montréal (Canada); the McGill University Healthcare Centre. It examines the motivations and barriers involved in the evolution of commuting characteristics, using the theoretical framework of mobility biographies. The empirical analysis includes a large dataset of independent variables, applying a multinomial logistic model in order to explain the transition of the employees’ commuting satisfaction. With regard to the measurement of change in commuting satisfaction, the findings confirm the role of attitudes, while taking into account the contextual differences before and after relocation. The change in travel time is found to be an important factor in the evolution of commuter satisfaction, whereby reduced commuting time improves satisfaction, as expected. In addition, the more an employee is attached to the new workplace, the more the commuting satisfaction will increase. The results provide further evidence that the meaning of the workplace goes beyond a location or a space, and opens up new avenues for research in travel behavior.     

Effects of visual factors during automated driving of mobility scooters on user comfort: An exploratory simulator study

An automated mobility scooter is expected to provide convenient and safe transportation for users in their living area. However, there is limited research on user comfort compared to that on user safety for the automated driving of mobility scooters. Because the user does not perform driving tasks in automated driving, the visual information from the peripheral environment and visual behavior is expected to closely affect the psychological comfort of the user. This study clarifies the effects of factors related to the automated driving of mobility scooters and the peripheral environment on the visual behavior and psychological comfort of the user. Effects of driving velocity and pedestrian density on the visual behavior and psychophysiological responses of users were investigated via a driving simulator. The results showed that automated driving in an environment with a high pedestrian density can result in a decrease in fixation duration, deactivation of visual processing, sympathetic activation, and feeling of negative emotion. This implies that the assessment of visual behaviors of users is important for the design of automated mobility scooters to improve user comfort.     

Evaluation of two short-term stress interventions in the context of mobility

ObjectivesIn our lives we experience different types of stress that emanate from a variety of situations. This stress can potentially spill over into unrelated situations, including the operation of a vehicle in a safe manner. It is not well known which types of countermeasures can actually mitigate such stress during driving. For this purpose, one needs valid stress intervention methods for the different types of stress that commonly occur during driving. In this study, it was therefore evaluated whether or not two stress interventions were effective in reducing stress. These two stress interventions were Positive Psychology–i.e., being an activity to reflect about thankful moments–and Biofeedback–i.e., being an activity aimed at continued relaxation based on the display of the participants own stress level.MethodsA study with 41 (n = 21 male) participants was conducted in a stationary vehicle to evaluate the effectiveness of Positive Psychology and Biofeedback on stress reduction. Stress was induced using the Stroop Task. During a Stroop Task high stress is caused by naming color words displayed in another, incongruent color. In the Baseline Condition, participants looked at neutral images, which were expected to have no effect on stress levels. These conditions were then compared.FindingsThe results revealed that participant stress levels were significantly higher during each stress induction period in comparison to each stress intervention period. This indicated that a reduction of stress is possible by administering stress interventions in a stationary setting. Yet, there was no difference between Positive Psychology, Biofeedback, and the Baseline Condition, supposedly due to the short administration, stress-reducing attributes of the Baseline Condition itself, or regression to the mean effects.NoveltyThe overall goal of this research is the development of stress interventions to target different types of stress that can occur in the context of mobility, an application context not yet investigated. These interventions are expected to improve well-being and safety inside the vehicle by improving concentration, attention, and psychomotor control, which can be reduced by high stress. The study took a first step to achieve this goal by developing and evaluating Positive Psychology and Biofeedback as stress intervention activities to mitigate stress in a stationary vehicle–a situation comparable to automated driving. The developed interventions showed stress-reducing effects in the stationary setting whereas looking at neutral pictures–although serving as the baseline–was similarly stress-reducing. This enables the next step–adding the task of manual driving to the interventions to look into both the effectiveness of the interventions during manual driving and driving safety at the same time.     

Shedding light on the psychological and behavioral determinants of travel mode choice: A meta-analysis

Mobility represents a relevant topic from the standpoint of environmental degradation, health-related consequences and social inclusion. Since private mobility is responsible for the greatest share of polluting emissions, it is necessary to gain deeper understanding of the mechanisms underpinning the choice of individuals to use either cars or alternative, environment-friendly transport modes. A meta-analysis on 58 primary studies is conducted to synthesize evidence on the determinants of travel mode choice, as regards both behavioral intentions and actual behaviors. Results suggest that, besides intentions, habits and past use represent the most relevant predictor, followed by constructs referring to the Theory of Planned Behavior framework. Environmental variables, on the other hand, play a relevant role in shaping behavioral intentions while their effect on actual behaviors is negligible, so that a deep intention behavior gap emerges. A moderator analysis is performed to explain the high heterogeneity in the results. Behaviors’ operationalization and measurement emerges as the moderator affecting heterogeneity of outcomes the most; trip purpose, sample type and year of the study also show a moderate effect on heterogeneity, while location does not appear to be a relevant moderator.     

Exploring the characteristics of potential and current users of mobility scooters,among older people in Israel

Recognizing the decline in the ability of older people to serve as vehicle drivers and their physical limitations for long walks, mobility scooters are considered as an alternative mobility means for older people. An increasing popularity of scooters is recently being observed in Israel, raising safety concerns. This study explored the characteristics of potential users of mobility scooters among older people in Israel and the behaviours of their current users, by means of an opinion survey and field observations in urban areas. The opinion survey applied structured interviews, with 110 persons aged 65+. The survey's results showed that most people agreed that scooters may improve their mobility and quality of life. However, they expressed a relatively low willingness to use scooters, mostly, due to the preference for private cars but also the lack of appropriate infrastructure for safe scooter travel in the city. An increasing potential for scooters' use was associated with ages 70–84, people who are aware of their health problems and less involved in physical activities but still maintain an active lifestyle, living independently and appreciating scooter benefits. The observations included 55 video-records with older scooter riders. They showed that regardless the types of urban road or junction, the majority of scooter riders behaved like a vehicle, i.e. travelled on the roadway. Scooters' moving on a sidewalk did not create conflicts with pedestrians, while scooters travelling on the roads sometimes disturbed vehicle flows and created dangerous situations. To ensure safety of the scooter users, their travels on the sidewalks should be stimulated and, thus, appropriate adjustments of urban infrastructure are required.     

The evolution of the boundaryless career concept: Examining physical and psychological mobility

Although there has been increased interest in the boundaryless career since the publication of Arthur and Rousseau’s book (1996), there is still some misunderstanding about what the concept means. This article examines the boundaryless career and presents a model that attempts to visually capture Arthur and Rousseau’s suggestion that the concept involves six underlying meanings. Rather than considering whether or not an individual has a boundaryless career, the model focuses on the degree of mobility reflected in a career along two continua: one psychological, one physical. Based on the model, we suggest five propositions and a series of directions for future research.     

A factor analysis for identifying people with disabilities’ mobility issues in built environments

Neighborhood built environments (BE) have been recognized as an important aspect that can, directly and indirectly, impact people with disabilities’ mobility. While many efforts have been made to improve the quality of BE, people with disabilities still perceive inequality in BE. The objective of this study is to identify the factors influencing people with disabilities’ attitudes toward BE that can facilitate or suppress their mobility, using exploratory factor analysis. This study specifically focuses on people with physical disabilities and people with visual impairments living in Austin, TX and Houston, TX metropolitan areas in USA. Data was gathered through an online survey. This study identified three factors from the sample: 1) barrier-free BE; 2) BE supporting safe travel; and 3) walkable BE. In addition, the factors were compared according to the respondents’ demographic information, such as income level, disability type, and private car use availability in households. Regarding income level, low-income individuals with disabilities perceived BE more negatively than their counterparts did. As for private car availability, people with disabilities who have no car in their households had a more negative perception of BE. However, no differences were found in the attitudes across disability types. This study contributes to understanding what BE factors are important for people with disabilities. The findings suggest the importance of establishing more targeted and prioritized strategies, considering people with disabilities’ neighborhoods and individual characteristics, for the improvement of their mobility.
