Access to the city: Mobility patterns,transport and accessibility in peripheral settlements of Dar es Salaam

This paper is concerned with access to the city for urban residents living in the periphery of Dar es Salaam, Tanzania. The paper presents an analysis of the mobility practices of residents and investigates the mobility constraints they experience in relation to the limited accessibility provided by the urban transport system. The paper draws upon qualitative interviews with residents in the periphery as well as recently collected travel speed data and offers a unique combination of testimony with GIS-based modelling of overall accessibility. A central finding is the overall importance of regular mobility and access to the city for residents in the periphery. Regular mobility is an ingrained part of residents' livelihood strategies. The majority of households rely on one or more members regularly travelling to central parts of the city in relation to their livelihood activities. The analysis reveals a widespread, near-to-universal, dependence on motorized transportation, with the vast majority depending on public transport. Raster-based modelling of overall accessibility provides an indication of the very high travel times endured by residents in the periphery. The analysis identifies and distinguishes between three overall mode types: 1) Private car, 2) public transport and 3) motorcycle/car combined with public transport. While private cars appear marginally faster, differences in travel times are actually limited. This suggests that travel times are less influenced by mode of transport than by road and traffic conditions and highlights how accessibility problems of peripheral settlements are not easily understood separately from the general dysfunctions of the overall mobility system of city.     

Transport,urban development and the peripheral poor in Colombia — Placing splintering urbanism in the context of transport networks

In rapidly growing cities the evolution of utility and communication infrastructures has enabled the creation of ‘premium networked spaces’ exclusively for wealthier groups thus deepening already large social inequalities. By the same token, in a context of spatially concentrated income-earning opportunities and other urban functions, as well as limited purchasing power, accessibility to adequate means of connectivity with the rest of the urban fabric can be a determining factor in overcoming conditions of poverty for residents in physically marginal areas.Within the framework of the splintering urbanism thesis, and using the case study of Soacha, a municipality adjacent to Bogotá, Colombia's capital city, we examine the apparent mismatch between the growth of low-income informal settlements in peripheral locations and the development of transport networks in the period 2000–2010. Our aim is to identify the effects on social and spatial marginalisation of an uneven provision of material infrastructures and services for mobility. We identify central elements in the structure of the networks of connectivity between Bogotá and Soacha, highlighting the main gaps that lead to a fragmented set of connections. We develop a set of criteria for planners and policy makers searching for a more informed analysis of transport supply and policy development practice for poor peripheral populations in similar regions and contexts.     

An intersectional analysis of barriers to cycling for marginalized communities in a cycling-friendly French City

In French cities like Grenoble, cycling is an increasingly popular form of urban mobility. Yet a lack of disaggregated modal data makes it unclear who does and who does not have access to biking. An intersectional analysis of 19 narrative and semi-structured interviews with policymakers, residents with different identities, and bike service providers demonstrate that some people perceive unique barriers to biking, related to their identities. For example, this study finds that racism, financial precarity, a lack of accessible information about services, and spatial inequalities may prevent some people from biking despite Grenoble's advanced cycling infrastructure and services and that these barriers may compound for certain people, reinforcing the preliminary body of research on intersectional barriers to urban biking. The study further finds that the lack of disaggregated demographic data on urban mobility in France might be preventing inclusive bike policy. The paper concludes by arguing that local policymakers would benefit from applying an intersectional analysis in understanding who is and is not biking, to promote everyday biking in a more inclusive way.     

Who could benefit from a bus rapid transit system in cities from developing countries? A case study from Kampala,Uganda

The present rapid urban growth of cities from developing countries causes negative externalities such as lagging infrastructure development. In combination with rapidly rising motorized vehicle use this leads to severe traffic congestion affecting the mobility of the urban residents. Therefore many urban governments are planning to improve their transport and mobility situations with mass rapid transit systems of which a bus rapid transit (BRT) is a rather easy system to implement at reasonable costs. However, due to high urban inequalities the effects of urban traffic and potential improvements of the urban transport system for the diverse group of urban residents can differ significantly. In our case study Kampala (Uganda) four main groups were identified through cluster analysis of socio-economic and residential data gathered through interviews: extreme poor, poor, middle income and rich. Each group experiences a different mobility with the extreme poor being the most vulnerable group. The planned BRT system aims to decrease the average travel time but risks to exclude the lowest income class since not enough attention is paid to the affordability of the system to all residents. Therefore we argue for a policy that works from bottom up and pays attention to the internal diversity of the population.     

How can GPS/GNSS tracking data be used to improve our understanding of informal transport? A discussion based on a feasibility study from Dar es Salaam

Informal transport is an important factor for people's daily mobility in most developing countries, in urban as well as in rural areas. It has grown rapidly in recent years and influences cities' appearances all around the world. But little is known about its operation, as informal transport is highly dynamic and its operation mostly unregulated by the state. This paper discusses how informal transport can be better understood by using GPS tracking data. The methodology is exemplified using results from a feasibility study from Dar es Salaam. The results show that GPS tracking has great potential to provide insights into the functionality of informal transport, such as its role as a feeder mode in the transport system, as well as into the comparative advantages and disadvantages of different modes of transport. Moreover, by delivering spatially locatable information on mobility developments, it can deliver important information for integrated planning with regard to better coordinating the interwoven developments of urban settlements, growing mobility demand, and transport supply.     

Livelihoods in motion: Linking transport,mobility and income-generating activities

During the past decade, there has been an increased focus on mobility in the social sciences linked to the so-called ‘mobility turn’, which claims that as mobility is so pervasive it should not be viewed as a rupture in society but as a normal way of life. This is certainly the case in urban contexts of sub-Saharan Africa where mobility forms an integral part of livelihood and income-generating activities. Drawing on in-depth qualitative research conducted in Accra, the capital of Ghana, this paper explores the mobility of urban residents in differing parts of the city in relation to their livelihood strategies. Through illustrating the ways in which the mobility of urban residents is aided or hindered by Accra's transport system, and by examining how this in turn influences their livelihood strategies, the paper contributes to an alternative new mobilities paradigm that is more considerate of, and builds upon insights from, the global South where such research has a longer pedigree than in the global North.     

Bus rapid transit as a neoliberal contradiction

Bus Rapid Transit (BRT) is being implemented as a neoliberal project, but it creates contradictions that challenge the premise of neoliberalism. BRT projects are affordable rapid transit infrastructure, but they are also an impetus to restructure the urban bus sector in developing cities with informal mass transport. The dominant model of BRT implementation creates a market for bus service from large private companies where the government takes on the risk and brands the service as part of the city's attempt to be a ‘world class’ city that can attract mobile capital. However, BRT and the formalization of the bus sector can increase the power of urban residents by firmly putting transport in the public sphere; workers by increasing the incentives for collective action; and bus riders by prioritizing space for buses over cars. But these are only openings that require action to take advantage of the contradictions.     

Informal motorbike taxi drivers and mobility injustice on Hanoi's streets. Negotiating the curve of a new narrative

The central government of the Socialist Republic of Vietnam and Hanoi's municipal authorities are enthusiastically embracing a series of plans and policies for the capital city to create a sustainable mega-city. This state imaginary privileges ‘modern’ mobilities, championing highways, a bus rapid transport system, and an elevated metro, while so called ‘traditional’ means of moving around the city such as motorbikes, bicycles, or cyclos are being strongly discouraged and increasingly marginalised. For example, Hanoi officials are implementing a step-wise ban on motorbikes from downtown streets by 2030, while the majority of the urban population travels by motorbike, with about five million motorbikes plying the city's streets. While such an approach not only creates mobility injustice for lower socio-economic residents of the city as a whole, it threatens to undermine the livelihoods of thousands of informal motorbike taxi drivers (locally known as xe ôm). In this article I engage with the emerging mobility injustice literature to explore how state discourses regarding urban modernisation are impacting the possibilities for Hanoi's xe ôm drivers to maintain access to city streets and viable livelihoods. These drivers must negotiate emerging and often conflicting state policies, their enforcement, as well as new app-based competitors, all of which challenge the equitable distribution of motility and produce important frictions. Nonetheless, xe ôm drivers draw on their agency and creativity during their daily routines to push back, while also creating new narratives regarding their vital role in maintaining neighbourhood security. We thus see how marginalised individuals are counteracting policies they consider unjust, even when this urban agenda is embedded in a politically socialist context.     

Talking,walking, riding and driving: The mobilities of older adults

Through interviews with residents of an urban retirement community and users of a senior centre in an inner city neighbourhood this research uses the new mobilities paradigm to examine the relationships that exist between movement, non-movement, communicative travel and place-bound and place-creating social relations for older individuals. Our results show that these relationships can be conceptualized as forming non-linear multi-directional, locally-contingent mobility ‘systems’. Two such systems were identified: the first centred on the communal area within the retirement community and the second focused on the senior centre. The types of non-movement, movement and communicative travel that form each of these mobility chains, the number and variety of spaces connected and consequently the form and nature of the social relations created exhibit both similarities and differences. The mobility systems created by residents of the retirement community connect and flow through more spaces, involve a greater variety of movement and non-movement and are more varied than the senior centre users’ mobility chains. For both populations the place-bound and place-creating social relations that result from and generate movement, non-movement and communicative travel occur as individuals carry out daily errands and routines. For the users of the senior centre, interaction/participation by definition is the result of routine and repeated planned presence at the senior centre. Once at the centre, contact and participation predominately result from engaging in pre-arranged organised activities. For retirement community residents interaction occurs as a result of within-community movement, extensive travel outside the community and periods spent at home alone.     

Big data for big issues: Revealing travel patterns of low-income population based on smart card data mining in a global south unequal city

Smart card data (SCD) allow analyzing mobility at a fine level of detail, despite the remaining challenges such as identifying trip purpose. The use of the SCD may improve the understanding of transit users' travel patterns from precarious settlements areas, where the residents have historically limited access to opportunities and are usually underrepresented in surveys. In this paper, we explore smart card data mining to analyze the temporal and spatial patterns of the urban transit movements from residents of precarious settlements areas in São Paulo, Brazil, and compare the similarities and differences in travel behavior with middle/high-income-class residents. One of our concerns is to identify low-paid employment travel patterns from the low-income-class residents, that are also underrepresented in transportation planning modeling due to the lack of data. We employ the k-means clustering algorithm for the analysis, and the DBSCAN algorithm is used to infer passengers' residence locations. The results reveal that most of the low-income residents of precarious settlements begin their first trip before, between 5 and 7 AM, while the better-off group begins from 7 to 9 AM. At least two clusters formed by commuters from precarious settlement areas suggest an association of these residents with low-paid employment, with their activities placed in medium / high-income residential areas. So, the empirical evidence revealed in this paper highlights smart card data potential to unfold low-paid employment spatial and temporal patterns.     

Survey of E-scooter users in Vienna: Who they are and how they ride

In many cities around the world, electric (e-)scooters have emerged as a new means of transportation. They are often advertised as supporting modal shift towards more sustainable transportation and as a tool for enabling more equity in mobility. However, the environmental impact depends on how they are used and what kinds of trips they replace. Integration of e-scooters into urban transport systems also implicates discussions on fair road space allocation. In our study, we assess the socio-economic profiles and usage patterns of e-scooter users in Vienna, Austria. We differentiate between two basic groups of e-scooter users (renters and owners) and apply two different methods. Firstly, based on an online survey, we examine the age, gender and education of e-scooter users and we look into which kinds of trips (commuting, shopping or leisure) and which other means of transportation are replaced by e-scooter trips. Secondly, we analyse data from field observations at cycle paths in Vienna in order to determine the share of e-scooter riders and their gender distribution. We find that e-scooter users are more likely to be young, male, highly educated and residents of Vienna. According to the survey, there are considerable differences in usage between owners of private scooters and users of sharing schemes. Whereas in both groups, e-scooter trips mostly replace walking and public transport as a mode, e-scooter owners also show a considerable mode-shift from private car trips. These results implicate that e-scooter riders are additional users of cycling infrastructure. This puts further pressure on the current allocation of road space, which provides little space for active modes of transport. We conclude that city policies should address this competitive relationship adequately by allocating more space to safe and convenient cycling infrastructure and traffic-calmed zones. This could not only help ease the current challenges due to e-scooters but also provide better conditions for walking and cycling and thereby at the same time contribute to a more sustainable and equitable urban transport system.     

The future of walking in Europe: a Delphi project to identify expert opinion on future walking scenarios

There is increasing recognition of the importance of walking to the sustainability of cities, set against a continuing decline in everyday walking. This paper reports on a research project, which predicts trends in walking in Europe by 2010 by seeking opinion of experts who are knowledgeable about non-motorised transport. There is a consensus that there will be more walking for leisure and health, but less everyday walking. This will happen despite walking being seen as more important and there being more facilities, infrastructure, information and funding for walking.     

Microstories of everyday mobilities and opportunities in Bogotá: A tool for bringing capabilities into urban mobility planning

The Capabilities Approach is gaining relevance as a theoretical approach that can contribute to consider issues of mobility and justice. The approach helps to better understand how everyday urban mobility can contribute to individuals' capabilities, that is, their ability to freely be and do what one has reason to value. However, in relation to mobility the Capabilities Approach is still missing operational tools that can consider individual specificities and go beyond aggregate evaluations of urban transport systems. Drawing on a research project on urban mobility and human capabilities in Bogotá, the paper discusses how microstories of individual everyday mobilities could be a suitable analytical tool for describing the plural relationship between mobilities and capabilities. Microstories, defined as short accounts of personal everyday mobility experiences, help to account for the features that facilitate or impede individual mobility, and consider the manifold uses of mobility as achieved by each person, according to one's individual choices. The paper discusses three potential contributions of microstories: integrating established evaluative approaches, such as accessibility measures; providing elements for the design of more effective policy actions; expressing features of the mobility experience that, despite their relevance for personal preferences and behaviours, are difficult to include within aggregate evaluations. The usability of microstories as interpretative and operational tools is examined in the light of the obtained results and in relation to policy making processes.     

Household decision-making for everyday travel: a case study of walking and cycling in Lancaster (UK)

Increased walking and cycling for short journeys in urban areas has many obvious advantages yet so far gains from the promotion of more sustainable travel of this type are mostly small. This paper reports on a large research project which uses a mixed method approach to explore attitudes to and perceptions of walking and cycling, and which examines the process of household decision-making for everyday travel and the constraints that this imposes. Using survey, interview and ethnographic data it is argued that many people hold ambiguous and sometimes contradictory views of walking and cycling as effective means of everyday travel, that what they do rarely matches precisely what they believe, and that the complexity and contingency associated with everyday travel for many households is a major barrier to the use of more sustainable travel modes. It is suggested that better understanding of these processes could help to inform both future transport policy and the promotion of walking and cycling for short trips in urban areas.     

Economic,social and cultural transformation and the role of the bicycle in Brazil

This paper reviews the current socio-cultural and political state of cycling in Brazil and the policies and activities over recent years that have aimed to reverse its marginalisation. In particular it focuses on the city of Pelotas in the southern state of Rio Grande do Sul and the significant societal and material transformations that are causing conflict and dissonance in relation to the future role of cycling on city streets. Using a combination of empirical evidence from existing literature; a focus group with members of the cycling stakeholder forum; interviews with planning officials whilst observing cycle infrastructure; interviews with participants whilst taking part in a ‘protest’ bicycle ride (bicicletada); and on street intercept interviews with cycle commuters, this paper highlights the tensions, conflicts, aspirations and imaginaries of a city grappling with significant growth and urban transformation.     

Does cycling infrastructure reduce stress biomarkers in commuting cyclists? A comparison of five European cities

There is substantial evidence that the environment has an important impact on the use of bicycles. Changes in the built environment, such as cycling infrastructure provision, usually aim at improving the efficiency, enjoyability and safety of cycling. They can also shape affective responses, for instance by triggering or preventing stress situations during cycling. The repeated occurrence of intensely stressful events may make actual cyclists more likely to abandon cycling and deter prospective cyclists from actually taking up this form of mobility. Therefore, using a novel approach, based on stress biomarker measurements obtained directly from cyclists, the objective of this study is to investigate the relationship between urban environment and cyclists' stress. It also investigates if different types of cycling infrastructures in the contexts of two different countries and in five different cities have different relationships with stress. Using a stress sensor, 70 young adults were invited to cycle along a standard route in Oxford, London (the United Kingdom), Amsterdam, Houten and Groningen (the Netherlands). These routes were around 6 km long and had a wide range of characteristics. Multilevel logistic regression analysis indicates that the probability of stressful events occurring is significantly lower on physically segregated cycle paths than on cycle paths on streets, with cycling on general use streets falling in-between these extremes. We also find higher probabilities of stress for primary roads compared to tertiary roads, at intersections than on straight roads, on cobbled and off-road surfaces compared to asphalt, and in noisier places. Models for the individual cities suggested that the relationship between cycling infrastructure and the likelihood of stressful events occurring may depend on the local context. Only for noise conditions, intersection types and cycling infrastructures were the effects consistent across the cities. These findings may be useful for urban infrastructure planning and management, indicating specific attributes that should be adjusted to make cycling less stressful.     

The dynamics of modal shifts in (sub)urban commuting: An empirical analysis based on practice theories

A modal shift away from the private car onto low-carbon transport modes is an essential part of decarbonising the transport sector. The dynamics of modal shifts are, however, not yet well understood. In particular the interrelations between structural and individual dynamics require further investigation. Furthermore, a better understanding is needed of how new transport modes become integrated into existing mobility practices. In this article, we address these questions in a qualitative study of modal shifts in (sub)urban commuting in three major Swiss cities. We analysed the interview data by means of a qualitative content analysis informed by practice theories. We found that modal shifts can arise i) from dynamics related to the conditions of use of different transport modes, ii) the coordination of everyday mobility with other people, iii) the coordination of resources between different daily practices, and iv) from dynamics related to the intrinsic motivation of everyday mobility. We found that these different dynamics are intertwined and that to understand how modal shifts arise, they must be analysed conjointly, rather than in isolation. And we identified three patterns in how modal shifts play out, and which describe different ways in which the new transport mode becomes integrated into everyday mobility practices. The first pattern describes modal shifts which require no adaptation of existing commuting practices. The second pattern describes modal shifts after which a new everyday mobility routine must be built. And the third pattern describes modal shifts that coincide with a lifestyle change. We conclude by discussing the implications of our findings for decarbonising everyday mobility.     

Sidewalk fix,elite maneuvering and improvement sensibilities: The urban improvement campaign in Moscow

Drawing upon recent work on uneven development, neoliberal urban improvement, and everyday urban mobilities, I focus on the ways in which narratives of improvement intersect with infrastructural agendas for roads and sidewalks. While a lack of finances or political autonomy prevents many municipalities from investing in the maintenance of transport infrastructure, some capitals receive considerable central state resources directed towards ambitious infrastructural projects. I build a case about the current massive reconstruction of the Moscow center. I demonstrate that in the context of today's Moscow, neoliberal urban improvement becomes the mechanism for uneven development of the city in question but also of the country as a whole while everyday urban mobilities hardly become more sustainable. The case reveals the intersection of diverse trajectories of urban speculative development, experiences and sensibilities of citizens, and the circuits of power. Drawing on fieldwork conducted in 2015–2017, I contribute to the growing transport infrastructure literature by considering how prioritizing the nexus of improvement and rent-seeking results in subjecting citizens to various inconveniences and risks related to street refurbishment. I use three main concepts to make sense of Moscow's urban improvement campaign. I employ the concept of “improvement sensibilities” to theorize the translation of material and discursive components of the “My Street” campaign into practical and political effects. The trends around coping with transport congestion by introducing higher densities, walkability and public transport connections comprise, I argue, “the sidewalk fix” that combines attempts to restructure the built environment with the aim to continue rent-seeking and economic expansion. “Elite maneuvering” is engaged to capture the ways in which the accumulation of enormous rewards is variously secured by the Moscow authorities, including the use of the rhetoric of “comfortable city”.     

Pre-schoolers' transport imaginaries: Moving towards sustainable futures?

Being on the move is part of children's everyday life in cities. However, little is known about how young children experience transport systems or their aspirations for mobility in cities. In this paper, we explore pre-schoolers' experiences with the mobile world and show their affinity with different transport modes and hopes for their current transport system. We draw on a participatory research project that engaged children in class discussions, a tile-based city building exercise and neighbourhood walks. Findings suggest that although the voices of children aged 3–5 years are absent in mobility or transport debates, children are fascinated by mobility and transport related activities and services. Pre-schoolers from Dunedin, New Zealand, though recognising a predominantly motorised transport system, also showed creative or alternative modes making their way into their own transport systems. In this paper we argue that children should be introduced to and experience alternative modes of transport in the early years to allow for more imaginary transport geographies creating greater support for more sustainable, liveable urban environments for all ages.     

More than medical tourism: lessons from Indonesia and Malaysia on South–South intra-regional medical travel

While scholars increasingly acknowledge that most contemporary international medical travel comprises South–South flows, these have gone curiously unexamined. Rather, policy, scholarly and media attention focuses predominantly on North–South flows of ‘medical tourists’. However, this focus diverts attention from the actual and potential impacts of South–South intra-regional medical travel flows on both their source and receiving contexts. As such, we present findings from a study examining South–South intra-regional medical travellers' motivations, preparations and practices to better understand the social, economic and political situations that condition them and their effects on the destinations that receive them. Our study of Indonesian medical travellers pursuing health care in Malaysia draws on 35 semi-structured interviews with Indonesian patients, their companions, medical staff and agents in both countries. From this, we suggest that South–South medical travellers' diverse socio-economic conditions shape decision-making and spending behaviour relative to treatment, accommodation and transport choices as well as length of stay. We identify ways in which informal economies and social care networks sustain the formal medical travel industry. Finally, we observe how medical travel increasingly serves as a means through which chronic and everyday health needs are met through temporary, visa-free intra-regional movement.
