Understanding the value and vulnerability of informal infrastructures: Footpaths in Quito

Walking remains the primary means of travel in informal settlements of the Global South because of the limited ability of municipal governments to provide formal transport infrastructure. To cope, residents create footpaths through a bottom-up approach. Using a case study of informal settlements in Quito, this paper offers the first study of the process through which people settled in these spaces shape footpaths as informal walking infrastructures to enable everyday mobility. The paper draws on data collected over an eighteen-month period from archives, field notes from participatory observations, records of in-depth interviews, and interviews “on the go” with pedestrians to show how this infrastructure enables informal settlements' residents to access everyday destinations in shorter times, less expensively, and (often) more safely than alternatives. We show how these informal infrastructures build on centuries old practices of collective footpath building that form an essential part of local culture, and how urban processes and infrastructural development in the core city shape the production, transformation and disappearance of footpaths in informal settlements. Significantly, these findings contribute to a fuller understanding of the value and vulnerability of informal infrastructures that can inform wider studies of walking and informal infrastructure. The paper concludes by identifying the challenges and opportunities to promote informal infrastructures as a mainstream element of mobility in the city and support a more sustainable path to urban development.     

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.     

Analysis,modeling, and assessing performances of supply chains served by long-distance freight transport corridors

This article deals with an analysis, modeling, and assessing performances of supply chains served by long-distance intercontinental intermodal rail/road- and sea-shipping freight transport corridor(s). For such a purpose, the supply chains are defined and the methodology for assessing their performances under given conditions is developed. The methodology consists of the analytical models of indicators of the operational, economic, environmental and social performances of particular corridors and corresponding supply chains assumed to be dependent on the infrastructural and technical/technological capabilities. The models of particular indicators have been applied according to “what-if” scenario approach to assessing performances of the long-distance intercontinental inland and maritime freight transport corridors spreading between China and Europe in the scope of the “Silk Road Economic Belt” and “A New Maritime Silk Road” policy initiative. The results prove that the intermodal inland rail/road alternative could act as a serious competitive alternative to its maritime deep-sea counterpart under given conditions. Nevertheless, in order to realize the opportunities, large investments in the inland rail/road infrastructure are required to appropriately connect China with Europe.     

Citizen participation for sustainable transport: the case of “Living City” in Santiago,Chile (1997–2012)

Twentieth century citizen “revolts” against urban highway projects have influenced thinking about public transport (Toronto, Vancouver, New York), governance (Portland), and cycling (The Netherlands) to this day. Less is known, however, about how these emerge in developing countries, and what they can tell us about citizens’ role in innovation to achieve more sustainable transport systems. This case study examines a social movement that emerged in opposition to the country’s first major highway concession, in Santiago, Chile (1997), challenging and changing urban planning paradigms. In 2000, the anti-highway campaign founded a citizen institution, Living City (Ciudad Viva). Twelve years later, it has become a prize-winning, citizen-led planning institution.Although the role of citizen participation in improving transport systems has become increasingly recognized in recent years, it still tends to be rather ritualistic. This experience offers insight into how strategic approaches to participation can reinforce the role of self-organizing civil society organizations in introducing innovation into existing systems. Findings suggest that traditional large movements, which are mainly useful for one-way communication of information, require support from small groups able to deliberate in a transformative sense, with more attention paid to how new consensuses can be transmitted through the relational networks of those involved. Moreover, this experience suggests that thinking about citizens as planners in their own right, rather than as mere participants at specific points in a planning process, opens the way to more effective strategies for innovating in transport, to address the social, environmental, and other challenges humanity faces today.     

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.     

Urban transport policy transfer: “bottom-up” and “top-down” perspectives

The paper provides insights into the urban transport policy transfer process, focusing particularly on the transfer of the transport policy within the EU. The themes of the paper are structured according to five of the “Dolowitz and Marsh questions”: what is transferred?; why do actors engage in policy transfer?; who are the key actors involved in the policy transfer process?; from where are the lessons drawn?; and what restricts or facilitates the policy transfer process? The methodological approach taken for considering each question involves two steps. Firstly, a “bottom-up” step considers the views of policy transfer from a “city perspective”, for which use is made of results from interviews recently carried out within the EU project “Transport Research Knowledge Centre” (TRKC). These interviews were intended to ascertain the information needs of seven “representatives” of European cities, all of whom were involved in the Cities Reference Group of the EU project “Citymobil”. These seven cities have widely varying characteristics in terms of size and geographical location (across Europe). By discussing information needs, the interviewees provided many insights into the transport policy transfer process. Secondly, a “top-down” step considers the policy transfer questions from an “EU perspective’; use here is made of various transport policy documents published by the European Commission (EC). For each of the five questions, “bottom-up” and “top-down” perspectives are examined and compared. The final section of the paper draws conclusions, providing a number of recommendations to both city authorities and the EU on how urban transport policy transfer might be enhanced in the future.     

Transforming mobility justice: Gendered harassment and violence on transit

Mobility justice scholarship has shown that socially disadvantaged people experience uneven access to movement through various spaces and even ‘immobility’ based on their differential hold on resources and power. Scholarship on gendered mobilities demonstrates that public spaces, such as public transit, are structured in ways that serve to reproduce gender hierarchies. While much important work on gendered mobilities has focused on the unique limitations to mobility women experience in spaces such as public transport, there is little work that considers how other gender minorities experience mobility in these spaces. Drawing from 25 qualitative interviews with transgender and gender nonconforming public transit users in Portland, Oregon, this paper demonstrates that gender minorities experience significant challenges to their routine mobility on public transit. The consistency with which participants in this study experienced harassment, discrimination, and violence while attempting to use public transit suggests that scholarship on gendered mobilities must begin to theorize from a more expansive understanding of gender. Transport justice studies broadly, and the scholarship on gendered mobilities specifically, must move toward a more comprehensive understanding of the spectrum of gendered experiences that impact mobility and accessibility. The paper concludes with specific policy recommendations that could make direct impacts on the safety and comfort of transgender riders. While larger cultural and societal change is necessary to fully address these inequities, these smaller efforts would likely increase transgender people's use of public transportation.     

Walking,cycling, and public transport for commuting and non-commuting travels across 5 European urban regions: Modal choice correlates and motivations

The objective of this study was to explore individual and contextual-level characteristics associated with active (walking and cycling) and public transport as main travel modes for both non-commuting and commuting purposes, in residents of five European urban regions. We also described participant-reported motivations for modal choice for each journey purpose. The study used multilevel models to investigate cross-sectional associations of individual (i.e. age, gender, educational level) and contextual (defined by a combination of residential neighbourhood characteristics in typologies) characteristics with the choice of active and public transport as outcome. Based on an online survey of 6037 residents of Ghent and suburbs (Belgium), Paris and inner suburbs (France), Budapest and suburbs (Hungary), the Randstad (including the cities of Amsterdam, Rotterdam, The Hague and Utrecht in the Netherlands) and Greater London (United Kingdom), we observed associations with both individual and contextual characteristics.Results of the multilevel modelling show that the probability of using active or public transport as main mode varies depending on both individual and contextual characteristics. At individual level, relations with gender, age, education, weight status and having at least one child varied according to main transport mode and/or purpose. For example, overweight participants reported lower level of cycling for commuting and non-commuting travels than normal-weight participants. In the context of non-commuting travels, participants with one or more child reported less public transport use and more walking (vs participants without children). Among contextual-level variables, urban characteristics of the residential neighbourhood defined by four clusters (according to food environment, recreational facilities and active mobility opportunities) were associated with public transport and walking but not with cycling. For active transport the most important reasons were “I like to travel (on foot or by bike)” and “I want to be physically active” for both travel purposes. “Public transport facilities nearby” was indicated as the most important reason for public transport (for both trip purposes) – the second was “Journey time”.Our findings highlight the importance of exploring a combination of multiple correlates at individual and contextual level according to journey purposes and suggest that the role of health-related individual characteristics such as weight status need further exploration.

Global city regions and the location of logistics activity

The aim of this paper is to extend and develop research surrounding the links between transport and urban regions. An understanding of transport activity has long involved the use of spatial frameworks, seen in the idea of a gateway city (with its surrounding hinterland) and in the identification of hubs or nodes. The particular framework used here is the global city region, a build-out from the much researched global city, and acknowledged as the most prominent feature of spatial development in the global economy. As these areas can accommodate important sea and airport infrastructure, the global city region can be expected to play a significant role in global logistics. Whether that significance extends just from the physical realm, as reflected in the infrastructure, or whether it is embedded in the scale and complexity of the advanced business services sector within the global city, is the issue that lies at the heart of the research. The research has set out to answer the question: “How important are these regions in logistics activity?”. The question has relevance in the context of transport geography as it provides an urban structure perspective on what is commonly seen as separate port or airport activity. Its relevance is enhanced as its answer relies upon a simultaneous analysis of both sea and air freight activity. Results show these regions counted for a substantial and growing share of sea and air freight between 1996 and 2006. In accounting for that outcome the research explores the particular effect of infrastructure (showing that global city regions with multiple seaport and airports play a special role) and also isolates the links with global city functions. The paper concludes with some insight on the special challenge these places create for strategic urban planning policy.     

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.     

Job growth,accessibility, and changing commuting burden of employment centres in Melbourne

How transport and employment agglomeration enhance urban productivity is a fundamental problem for many cities. Internationally, there has been a great deal of interest in the effect of employment concentration on urban productivity, but very few studies have examined its effect on worker commuting burdens and transport costs. This paper aims to advance international knowledge by measuring job growth and costs of labour market access between 2011 and 2016 for employment centres (EC) in Melbourne, Australia. A comprehensive transport cost model is used that incorporates detailed transport costs and travel times associated with transport modes. By tracking job growth and changes in worker commuting burdens, this paper distinguishes ‘high-cost’ ECs from ‘low-cost’ ECs, for their respective labour pools, and identifies which ECs offer opportunities for better transport outcomes. The results show that well-planned public transport (PT) systems and residential development, coupled with walking and cycle networks, are important features of ECs experiencing lower commuting burdens. Drawing upon the conclusions, this research recommends more effective approaches by governments to foster effective investments in urban infrastructure and discusses how broader policy and investment decisions can align to optimise employment agglomeration and minimise negative transport impacts.     

Divergent infrastructure: Uncovering alternative pathways in urban velomobilities

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

Perceptions of cycling among high school students and their parents

Cycling is a healthy, low-cost, and low-carbon alternative to motorized transport. As a relatively fast active mode of transport, cycling can overcome the distance barrier of walking, while also providing cardiovascular exercise and reducing demand for motor vehicle travel. The “cycling renaissance” has seen an increase in the number of cyclists in urban spaces, and there is evidence of increased investment in cycling infrastructure and cycle skills training in some places. Yet the number of high school students cycling to school is declining in many industrialized countries. Transport to school is a major contributor to daily traffic congestion, resulting in both local and global environmental concerns, and high school students have been relatively overlooked in research to date. In this paper, we present empirical material from a qualitative study of high school students and parents in Dunedin, Aotearoa New Zealand. Focus group sessions were conducted during 2014 and 2015 with students and parents separately, to explore their perceptions of modes of transport and transport to school decision making. Key findings relate to perceived safety, implicit messages, and social norms. We find that a complex range of factors contribute to perceptions of cycling safety, including features and perceptions of the built environment, traffic safety (including behaviors of other road users), previous cycling experiences (including accidents), and adolescents' cycling skills and on-road experiences. Overcoming concerns through behavioral and cultural interventions coupled with upskilling and thoughtful infrastructure may present a pathway to increasing rates of cycling.     

Hot or not? The role of cycling in ASEAN megacities: Case studies of Bangkok and Manila

The Association of the Southeast Asian Nations (ASEAN) recognizes the role of nonmotorized transport for sustainable urban development in its policy framework. National and local policymakers in Thailand and The Philippines, two tropical countries without a tradition of urban cycling, are increasingly paying attention to cycling as well. This article aims to assess the current situation and progress in cycling, using Bangkok and Metropolitan Manila as case study cities, and to describe the necessary conditions for advancing the significance of cycling in tropical megacities. This is done by operationalizing the so-called Technological Innovation Systems (TIS) framework, which has been used in transition studies since 2008, however, never for cycling. As such this article also “tests” this framework for its application in sustainable transportation. The two case studies are characterized with regards to the current role of cycling in the mobility system, its infrastructure, governance system, and existing research on the potential and barriers. We find that TIS can readily be applied to our cases, with the analysis showing that elements such as knowledge development, actor networks, e-bike adoption, infrastructure, resource mobilization and legitimation are not well developed; on the other hand, flat terrain, attention for cycling for health and environment, heavy congestion, expansion of public transport, growing bike industry, active university communities, and the emergence of advocacy coalitions, could open up opportunities for increasing its modal share.     

The broader effects of transportation infrastructure: Spatial econometrics and productivity approaches

The importance of “broader” economic effects of transportation infrastructure has recently become apparent. “Broader” refers to impacts beyond the geographic boundaries within which the infrastructure investments are undertaken. Approaches to estimate “broader” impacts in production and cost function models are evaluated. A contribution of this paper is the empirical demonstration with a cross-section of US states’ manufacturing data that ignoring broader effects of a spatially lagged dependent variable can lead to mis-statements of the overall productive impacts of public infrastructure. These inaccuracies can arise because of missing indirect effects and from specification bias that may directly impact the infrastructure elasticity.     

Why cycling matters for Smart Cities. Internet of Bicycles for Intelligent Transport

This article develops the concept of “smart velomobility” that is concerned with networked practices, systems and technologies of cycling. The concept draws on velomobility, Smart Mobility/Intelligent Transport Systems (ITS), Smart Cities and the Internet of Things (IoT). The article presents results from an empirical study, where 80 riders of a networked fleet of e-bikes discuss their experience of smart velomobility. The results show how digital and physical mobilities merge, the way riders of the networked fleet interact with the data, how they share the data and how they feel tracked (privacy). The conclusion sketches out future research of “smart velomobilities” and also points out the policy and innovation potential of cycling as active, sustainable and networked mode of transport in the context of Smart Cities and the Internet of Things.
