In emerging markets, the amount of mobile communication and the number of occasions mobile phones are used are increasing. More and more settings appropriate or not for mobile phone usage are being exposed. Although prohibited by many governments, there is evidence that use of new mobile devices while driving are somehow becoming current everyday practice, hence legitimatizing usage for many users. Dominant dangerous behavior in the absence of enforced legal framework is being deployed and has become routine for many m-users. This chapter adopts a qualitative case study approach (20 cases) to examine the public transport drivers' motives, logic and legitimacy processes. The question which these issues raise in the light of advancing m-technologies is: How do, in the context of emerging market, undesired emerging routines enactment get to be reflected upon and voluntarily disregarded to maximize the benefits of m-technologies while minimizing their drawbacks? Findings point out at multiple motives for usage including external social pressure through the ubiquitous 24/7 usage of mtechnology, lack of alternative communication protocol, real time need for action and from an internal perspectives boredoms, lack of danger awareness, blurring of the boundaries between personal and business life and lack of job fulfillment are uncovered as key factors. As secondary dynamic factors such as education, drivers work' histories, impunity, lack of strong consumer opposition appear central in shaping the development of the routines. © 2011, IGI Global.

There are around 285 million visually impaired people worldwide, and around 370,000 people are registered as blind or partially sighted in the UK. Ongoing advances in information technology (IT) are increasing the scope for IT-based mobile assistive technologies to facilitate the independence, safety, and improved quality of life of the visually impaired. Research is being directed at making mobile phones and other handheld devices accessible via our haptic (touch) and audio sensory channels. We review research and innovation within the field of mobile assistive technology for the visually impaired and, in so doing, highlight the need for successful collaboration between clinical expertise, computer science, and domain users to realize fully the potential benefits of such technologies. We initially reflect on research that has been conducted to make mobile phones more accessible to people with vision loss. We then discuss innovative assistive applications designed for the visually impaired that are either delivered via mainstream devices and can be used while in motion (e.g., mobile phones) or are embedded within an environment that may be in motion (e.g., public transport) or within which the user may be in motion (e.g., smart homes). © 2013 Elsevier Inc.

The accompaniment of growth and development is the central thrust of child care in primary health care in order to contribute to the reduction of infant morbidity and mortality and promote healthy development. Despite its importance, the family health unit located in rural Parazinhocounty experiences the problem of frequent absences of children to follow-up consultations. Thus, this study aims to analyze the participation of mothers in the accompaniment of growth and development of children in the Family Health Strategy. This is an exploratory, descriptive study with a qualitative approach with the method action research, developed with mothers who are part of the monitoring of the growth and development of children in the rural area of the municipality of Parazinho/RN from May to October 2014. Data collection was performed using the focus group techniques, participant observation and individual interviews. Data were analyzed using thematic analysis of categorization. The study was approved by the Research Ethics Committee, under the opinion embodied 617,559 and CAAE 28598014.7.0000.5537. In step situation analysis, were conducted two focus groups, attended by a total of 14 mothers of different rural locations. From the speeches, one realizes that they have a satisfactory understanding of the monitoring of the growth and development of the childwas a learning moment. The nurse was mentioned as key professional that actionof accompaniment. The main reason that mothers to abandon consultations is access to health services, due to the distance from their homes to the basic unit, the shortage of public transport for the movement of users and delay between the service and the back home. As a strategy to try to tackle these problems, at the suggestion of their mothers was created Monitoring of Growth and Development Itinerant, where the FHS team moved to rural locations, performing activities related to children's health. Mothers who participated in the action approved the initiative as improving access and care of health needs, despite indicate dissatisfaction as the poor infrastructure and little privacy in consultations. Therefore, it is concluded that, despite the difficulties encountered often for lack of management support and involvement of some professionals, the monitoring of growth and development itinerant proved to be an important tool in solving the problem of access to services oriented to the health of child, in addition to functioning as a space for the realization of health education, becoming, since then, an activity inherent in family health team schedule.

New ways of sociability can be perceive in a historical context marked by the social change. The investigation developed by this thesis follow this idea, pointing the emergency of social relations established between individuals in drift. The foremost aim of this research was to assay, using a case study, the bonds constructed among the people that attend the Terminal Central - Pratic Shopping of Uberlândia-MG, the main responsible for the reception and distribution of public transport of the city. With the growth of the urban centers, their population became attractive objects of analysis in the social science field and the understanding of the city, in their core, by the dwellers displacement. Thus, after the separation of the people that use the Terminal Central in seven groups (students, families and couples, elderly, deaf and/or mute, employees of the stores in Terminal and of the bus companies), their interactions tried to be understood, by identifying the similarity with the sociability in traffic studies. In places with a great flow of people, the sociability in traffic suggests bonds of friendship, kindness, as foray, impersonality, frailty and the sudden break of contact.

The purpose of this research is to investigate how international students negotiate encounters with Irish students and construct ‘meaning’ from those encounters in the spaces of the university and city. As cities are increasingly characterised by a multiplexity of diversity, the issue of living with difference is becoming more and more pertinent. In the wake of escalating socio-spatial polarisation, inter-cultural tension, racism, and xenophobia, the geographies of encounter seek to untangle the interactions that occur in the quotidian activities and spaces of everyday life to determine whether such encounters might reduce prejudice, antipathy and indifference and establish common social bonds (Amin 2002; Valentine 2008). Thus far, the literature has investigated a number of sites of encounter; public space, the home, neighbourhoods, schools, sports clubs, public transport, cafes and libraries (Wilson 2011; Schuermans 2013; Hemming 2011; Neal and Vincent 2011; Mayblin, Valentine and Anderrson 2015; Laurier and Philo 2006; Valentine and Sadgrove 2013; Harris, Valentine and Piekut 2014; Fincher and Iveson 2008). While these spaces produce a range of outcomes, the literature remains frustrated by a lack of clarity of what constitutes a ‘meaningful’ encounter and how such encounters might be planned for. Drawing on survey and interview data with full-time international students at University College Cork, Ireland, this study contributes to understanding how encounters are shaped by the construction and reproduction of particular identities in particular spaces, imbuing spaces with uneven power frameworks that produce diverse outcomes. Rather than identifying a singular ‘meaningful’ outcome of encounter as a potential panacea to the issues of exclusion and oppression, the contention here is to recognise a range of outcomes that are created by individuals in a range of ways. To define one outcome of encounter as ‘meaningful’ is to overlook the scale of intensity of diverse interactions and the multiplicity of ways in which people learn to live with difference.

Safety on public transport is a major concern for the relevant authorities. We
address this issue by proposing an automated surveillance platform which combines data from video, infrared and pressure sensors. Data homogenisation and integration is achieved by a distributed architecture based on communication middleware that resolves interconnection issues, thereby enabling data modelling. A common-sense knowledge base models and encodes knowledge about public-transport platforms and the actions and activities of passengers. Trajectory data from passengers is modelled as a time-series of human activities. Common-sense knowledge and rules are then applied to detect inconsistencies or errors in the data interpretation. Lastly, the rationality that characterises human behaviour is also captured here through a bottom-up Hierarchical Task Network planner that, along with common-sense, corrects misinterpretations to explain passenger behaviour. The system is validated using a simulated bus saloon scenario as a case-study. Eighteen video sequences were recorded with up to six passengers. Four metrics were used to evaluate performance. The system, with an accuracy greater than 90% for each of the four metrics, was found to outperform a rule-base system and a system containing planning alone.

The total traveling with different types of transportation has increased drastically since the 50´s. Despite this increase, the use of the public transportation has decreased in percentage which has its explanation in the overall increased use of cars as transportation. Many researchers believes that better traffic information in the public transport can lead to increased use. Therefore this study aims to investigate how mobile personalized real-time information can increase customer satisfaction in the public transport in order to maintain and attract more travelers. The study addresses the problem through a case study at the Swedish transit agency Tågkompaniet, where customers and staff are studied in order to map the present situation regarding information in the public transport. The case study also sets out to investigate which type of real-time information that is considered to be most important for the travelers. At last the study also investigate which types of technical solutions that is needed, and how the needs of travelers can be considered to be able to offer mobile personalized real-time information. The findings are that there is a dissatisfaction regarding the transit information among both travelers and staff, and that their needs and demands must be met to a greater extent in order to increase the customer satisfaction. Furthermore, the findings are also that information attributes regarding delays and disruptions in the public transport is considered to be most important by travelers. Functions such as subscribe to information, push notifications and information associated with the transit ticket are necessary to be able to provide travelers with mobile personalized real-time information. Lastly the study provides a tool to consider traveler needs in development and evaluation of mobile personalized information systems within the public transport.

Drawing on an empirical study of public transport, this paper studies interactive value formation at the provider—customer interface, from a practice—theory perspective. In contrast to the bulk of previous research, it argues that interactive value formation is not only associated with value co-creation but also with value co-destruction. In addition, the paper also identifies five interaction value practices — informing, greeting, delivering, charging, and helping — and theorizes how interactive value formation takes place as well as how value is intersubjectively assessed by actors at the provider—customer interface. Furthermore, the paper also distinguishes between four types of interactive value formation praxis corresponding with four subject positions which practitioners step into when engaging in interactive value formation.

Over the last two centuries many major cities have undergone large-scale modernisation that has led to the growing sense of homogenisation associated with such locales across the globe. The fractal logic that is at the heart of so many urban settings, where the whole system is made up of parts that are identical to the whole, seems to serve in making anonymous everyday experiences. Public transport and its corresponding street furniture, if thoughtfully designed and planned, has the potential to form an integral element in the promotion of a sense of identity, interconnectedness and flow within a city. Furthermore, bus stops, benches, litter bins, curb-sides, posts and pavements, to mention a few, offer interesting cases to consider how people truly engage with contemporary urban spaces. These objects—part of routine and made familiar—are elements of daily lives that are ingredients towards visual and multi-modal experiences. In addition, these are places where individuals encounter sociality and materiality in ordinary and sometimes extraordinary ways. This paper uses a visual ethnographic approach towards exploring the human traces of routine activities that have an impact on the cityscape. An Investigation of these details found within the urban landscape lead us towards understanding how we engage with and navigate cities. This is essentially an urban archaeological study that looks to reveal how non-designed phenomenon in urban places can contribute to our image of a city, providing a reflection on homogeneity within the built environment. Our visual ethnography focuses on six major cities: two each in Britain, Europe and North America. The findings of this work illustrate through visual analyses three key characteristics: first, how urban spaces are transformed intentionally and unintentionally; second, how transformations are practical, functional, beautiful and sometimes ridiculous; third, how transformations reveal values around visual and multi-modal experiences inherent to people.

Electrical Bus Rapid Transit (eBRT) is a charging electrical public transport which brings a clean, high performance, and affordable cost alternative from the conventional traffic vehicles which work with combustion and hybrid technology. These buses charge the battery in every bus stop to arrive at the next station. But, this charging system needs an appropriate infrastructure called pantograph, and it requires a high precision bus location to maintain battery lifetime, energy saving and charging time. To overcome this issue Vicomtech and Datik has planned a project based on computer vision to help to the driver to locate the vehicle in the correct place. In this document, we present a mono camera bus driver guided fast algorithm because these vehicles embedded computers do not support high computation and precision operations. In addition to the frequent lane sign, there are more accurate geometric beacons painted on the road to bring metric information to the vision system. This method uses segmentation to binarize the image discriminating the background space. Besides it detects, tracks and counts different lane mark contours in addition to classify each special painted mark. Besides it does not need any calibration task to calculate longitudinal and cross distances because we know the lane mark sizes.

A densely built environment is a complex system of infrastructure, nature, and people closely interconnected and interacting. Vehicles, public transport, weather action, and sports activities constitute a manifold set of excitation and degradation sources for civil structures. In this context, operators should consider different factors in a holistic approach for assessing the structural health state. Vibration-based structural health monitoring (SHM) has demonstrated great potential as a decision-supporting tool to schedule maintenance interventions. However, most excitation sources are considered an issue for practical SHM applications since traditional methods are typically based on strict assumptions on input stationarity. Last-generation low-cost sensors present limitations related to a modest sensitivity and high noise floor compared to traditional instrumentation. If these devices are used for SHM in urban scenarios, short vibration recordings collected during high-intensity events and vehicle passage may be the only available datasets with a sufficient signal-to-noise ratio. While researchers have spent efforts to mitigate the effects of short-term phenomena in vibration-based SHM, the ultimate goal of this thesis is to exploit them and obtain valuable information on the structural health state. First, this thesis proposes strategies and algorithms for smart sensors operating individually or in a distributed computing framework to identify damage-sensitive features based on instantaneous modal parameters and influence lines. Ordinary traffic and people activities become essential sources of excitation, while human-powered vehicles, instrumented with smartphones, take the role of roving sensors in crowdsourced monitoring strategies. The technical and computational apparatus is optimized using in-memory computing technologies. Moreover, identifying additional local features can be particularly useful to support the damage assessment of complex structures. Thereby, smart coatings are studied to enable the self-sensing properties of ordinary structural elements. In this context, a machine-learning-aided tomography method is proposed to interpret the data provided by a nanocomposite paint interrogated electrically.

Background: The aim of this study was analyze associations between the practice of walking and environmental perception among elderly Brazilians in a region of low socioeconomic level. Methods: A cross-sectional study was conducted among 385 elderly people aged 60 years and over. To evaluate walking, the International Physical Activity Questionnaire (IPAQ), long version (leisure and transport modules) was used. The environment was evaluated by means of the Neighborhood Environmental Walkability Scale (NEWS) (adapted Brazilian version). For the statistical analysis, multiple logistic regression models were created separately for men and women. The practice of at least 150 minutes a week of walking was the dependent variable, and the variables of environmental perception were the independent variables. All the models were controlled for schooling level and age. Results: The proportion of elderly people active in walking was 56.9% for the men and 26.4% for the women. The perception of the presence of soccer fields (OR = 4.12) and their proximity, within ten minutes' walk from home (OR = 3.43), were associated with the practice of walking among the men. The perception of the presence of public squares (OR = 4.70) and the proximity of primary healthcare units, within ten minutes' walk from home (OR = 3.71), were associated with the practice of walking among the women. An association with adequate perception of vehicle traffic remained at the threshold of significance for the women. Conclusion: Accessibility of leisure structures such as football fields and public squares and of health services such as primary healthcare units were important environmental variables associated with the practice of walking among elderly people living in a region of low socioeconomic level in Brazil. These variables need to be taken into consideration when aiming to promote the practice of walking among elderly people living in similar regions.
