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.     

Assessing equity in transport accessibility to work and study: The Bogotá region

This research was aimed at exploring levels of equity in accessibility to employment and education in the city-region of Bogotá, Colombia's capital city. Building on consolidated methodologies for the assessment of potential accessibility, we estimate accessibility indicators at the zone level, evaluate how potential accessibility varies among income groups, and present evidence related to transport mode, in order to analyze social and spatial inequalities produced by the distribution of accessibility to employment and education activities. The research incorporates a method to evaluate how accessibility varies among zones according to average income and mode of transport in order to produce evidence-based arguments that can inform transport policy in the city-region of Bogotá, and other similar contexts in the Global South. Our results show strong distributional effects of the socio-spatial and economic structure of the city-region, its transport infrastructure and services, and the effect of current transport and land-use policies for citizens of different income groups. The tools and empirical evidence in this research seek to contribute to informed policy development in Latin America and other developing contexts, and feeding current debates on the role of accessibility in addressing social and spatial inequalities stemming from urban mobility.     

Spatial and temporal analysis of shared bicycle use in Limassol,Cyprus

Cities around the world are moving away from the car-centric infrastructure, urban design and planning policies prevalent since the 1950s and promoting sustainable mobility as an alternative, including cycling. As such, Bicycle Sharing Systems (BSS) have emerged as a transport innovation across the globe. Cycling modal share however remains low in most Southern European island cities. These cities exhibit certain characteristics considered as barriers to cycling, such as hot summers and high humidity, hilliness, and car-oriented culture and infrastructure. Despite this, BSS and policies promoting cycling have emerged in this region as well. These have the potential to provide alternatives for those marginalized by car-based mobility and to reduce traffic related diseases and injuries, noise and air pollution, which can contribute to an improved quality of life for all citizens. Using the Mediterranean island city of Limassol (Cyprus) as a case study, the utilization of bicycle sharing is investigated by constructing regression models to assess the influence of spatial and temporal factors on the demand for BSS use at stations. From the regression models it appears that land use factors such as residential, commercial and park land use, as well as the presence of the beach and cycling paths positively influences frequency of use, as does higher network connectivity. While higher tourist arrivals have a positive effect, the presence of hotels in a 300 m buffer around the stations does not. Higher rainfall, as well as higher temperatures, are associated with a decrease in BSS use. Explicitly incorporating spatial dependence, in Spatial Auto-Regressive (SAR) models, led to the formulation of models with comparable or better explanatory power, when compared to the Ordinary Least Squares (OLS) models. The insights from the regression models can be used to inform policies promoting cycling and the design and planning of BSS (expansion) in Limassol and other cities.     

Insights into carsharing demand dynamics: Outputs of an agent-based model application to Lisbon,Portugal

Two important claims for carsharing systems are their increased flexibility and potential contribution to reducing transport externalities such as pollution. Carsharing typically involves a fleet of vehicles in stations around a city that clients may use on an hourly-payment basis. Classical round-trip systems address a niche market of shopping and errand trips. However, a growing market is now arising providing one-way trips to clients. Great uncertainty remains on the economic viability of this type of carsharing given the complex relation between supply and demand, and how this may influence the level of service provided. Realistic modeling tools that include both supply and demand characterization and allow testing several carsharing operational parameters are scarce. In this sense, a detailed agent-based model was developed to simulate one-way carsharing systems. The simulation incorporates a stochastic demand model discretized in time and space and a detailed environment characterization with realistic travel times. The operation includes maintenance operations, relocations and reservations. The model was applied to the case-study city of Lisbon. Our results show that comparing to other modes, carsharing performs worse than private cars both in terms of time and cost. Nevertheless, it clearly outperforms taxis in terms of cost, and outperforms buses, metro and walking in terms of travel time. The competitiveness of carsharing is highly determined by trip length, becoming more competitive than other modes (travel-time wise) as trips become longer. The operational policies as car-fleet relocation and car reservation showed significant effects in enhancing profit while preserving good customers' satisfaction.     

Night-time mobilities and (in)justice in London: Constructing mobile subjects and the politics of difference in policy-making

The growing interest in urban night-time economies and night-time transport policies presents an important context in which to examine how mobility justice is conceived and operationalised in policy-making. Literature on transport exclusion and transport justice documents the disadvantages experienced by different social groups and advances theoretical frameworks for distributive justice and transport accessibility. However, this literature has rarely considered the politics of whether and how mobility difference is recognised and planned for in transport policy, including issues of deliberative justice (participation) and epistemic justice (knowledge production). To address these research gaps, this paper engages with Sheller's (2018) theorisation of mobility justice and critically analyses the construction of mobile subjects in policy discourse on night-time mobility. We analyse policy documents part of night-time policy for Greater London to examine the extent to which the differentiated night-time mobilities across social categories (gender, age, ethnicity, income, etc.) are recognised – in other words, how the ‘politics of difference’ play out in transport policy-making. Findings show that the discursive construction of mobile subjects in London's night-time policy distinguishes between workers, consumers, and transport users, yet, these broad categories poorly account for differentiated mobility needs and practices. Publicly available data on differentiated night-time mobilities in London does not inform current policy discourse, obscuring disadvantages experienced by different groups of people moving through the city at night, and thus limits the capacity of existing policy interventions to address mobility injustices. These findings reaffirm the need for transport research to move beyond distributive justice and accessibility analysis, towards exploring the potential of thinking about distributive and epistemic justice for challenging the status quo of transport policy.     

Transport shaping space: differential collapse in time–space

Although the tyranny of distance has been reduced by cheaper and faster transport, important geographical differences remain. Transport provision varies enormously. Globalization is uneven. Location remains all-important as time/space relationships collapse differentially. Nodal situations change and the spatial qualities of centrality and intermediacy enhance the importance of strategically located hubs. There is growing recognition of transport’s environmental externalities. Access to transport remains unequal and restricted by income, disability, age and gender as well as by location.This paper re-examines the role of transport in shaping space and considers the differential collapse in time–space resulting from a succession of transport innovations over 200 years. It assesses effects of cheaper and faster transport on spatial development at local, national and international levels, effects of intermodality on land/sea transport systems and impacts of fixed links in removing transport barriers. It considers whether time/space relationships have been encapsulated accurately in abstract models of spatial development. The paper examines how cheaper and faster transport has increased environmental externalities in increasingly mobile societies. It also considers aspects of social exclusion resulting from restricted access to transport.     

Conceptualising tourism transport: inequality and externality issues

This paper raises several conceptual questions concerning the actual and symbolic representations of inequality and differentiation expressed in leisure and tourism mobility which have significance for members of host communities visited, transport and land-use planning in host areas, tourists and the tourism industry. Within this framework, the paper explores two sets of conceptual issues which are positioned at the interface of transport and tourism. First, transport has the potential to act as a gatekeeper to culture contact, constraining or encouraging host–tourist interaction. Second, the role of tourist mobility at a local level can be critical for issues of inequality and externality effects. The substantial tourism impacts literature has only occasionally addressed social dimensions of leisure transport's external costs, and the transport geography literature has rarely acknowledged the differentiation of tourists and non-tourists competing for transport and transport space. It is concluded that transport and land-use planners need to recognise and respond to tourism's externalities and their implications for inequality and sustainability issues.     

Informal,essential and embedded: Transport strategies in remote Sarawak

Transport is a main concern for people living in rural and remote communities around the world, where the absence of affordable and reliable transport often prevents access to education, health services and employment opportunities. In Sarawak, a state of Malaysia on the island of Borneo, many rural villages experience acute transport poverty. For their basic transport needs, people here rely on informal transport systems based on local social and cultural networks, which provide essential mobility.We apply Polanyi's concept of social embeddedness to explore mobility in this region, people's efforts to develop regional models of entrepreneurship but also the relative marginalisation of remote communities in terms of development and infrastructure provision and the resulting friction between local people, the companies involved in regional resource extraction activities and local government. Based on data collected between 2015 and 2017, we frame informal transport in this region as a form of Indigenous entrepreneurship that can help local communities achieve wider social and economic inclusion. Our research points to a more social type of entrepreneurship and economic practice, in which social relationships and community responsibilities play an important role. Our qualitative approach, including ethnographic methods such as semi-structured interviews and participant observation, underpins the groundedness of our data in the every-day experiences of the people who took part in the research.     

Bicycle equity in Brazil: Access to safe cycling routes across neighborhoods in Rio de Janeiro and Curitiba

In many Latin American cities, rapid motorization and population growth have resulted in unprecedented urban transportation challenges, with lower income populations disproportionately facing constraints to mobility as well as externalities like air pollution, traffic collisions, and the impacts of climate change. The construction of bicycle lane networks has been identified as an effective tool for increasing citizen's mobility and accessibility as well as combating the effects of motorization, but in cities where bicycle lane networks exist, it is not known if they have benefited different income groups equally. This paper assesses the extent to which bicycle lane provisioning has been equitable among neighborhoods in Rio de Janeiro and Curitiba. Both cities were found to have more than twice the supply of bicycle lanes in the wealthiest quintile than the lowest income quintile relative to area and population. A network analysis using a Level of Traffic Stress classification to categorize roads found that wealthier areas have more commercial areas accessible along safer cycling routes. Implications for cycling policy and future research are discussed.     

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 factors in residents' mobility in rural towns of China: Car ownership,road infrastructure and public transport services

The improvement of rural people's mobility in developing countries has informed many policies. Still, debates remain on which policies are efficient, for instance, building more roads, providing public transport or promoting car ownership. The empirical evidence for these debates at the national level remains scarce. As a result, this paper aims to provide fresh evidence for discussions by examining residents' mobility in China using nationwide survey data with 12,524 respondents from 119 rural towns. The results of the analysis show car ownership is the most significant factor influencing rural people's mobility than other factors. Higher car ownership relates to a higher travel frequency to counties or cities. Other kinds of transport vehicles (i.e. electric cars, motorcycles and electric bikes) also have positive but relatively weaker impacts on rural mobility. For public transport, it is more accessible to access bus stops, which encourages travel to higher-order centres rather than increasing the frequency of county bus services. The accessibility of high-quality road systems tends to have a negative influence and has combined effects with levels of local services. People from towns with insufficient local services and poor access to highways travel the most frequently to higher-order centres. This study highlights the critical role of road investments and car ownership enhancement policies in improving mobility. Moreover, this study also underscores the supplemental role of public transport services given the current low car ownership rates in rural towns of China and the global consensus on sustainable green transport development. It highlights the importance of engaging eco-friendly and locally adaptive transport alternatives, such as electric cars and electric bikes. It also calls for a rational distribution of bus stops and more flexible, convenient, and physically accessible public transport and carshare modes in rural China.     

Local accessibility inequalities and willingness to walk in Latin-American cities: Findings from Medellín,Colombia

As planning for accessibility is becoming a priority for most cities, policies encouraging short-distance traveling and the use of active modes of transport are gaining force. Emphasizing short-distance travel and localized practices can produce positive sustainable outcomes, but in order to design proper public policies, a deeper understanding of the determinants of this mobility of proximity is still needed. This paper uses mobility data from the city of Medellín, Colombia, to examine the role of local accessibility and the proximate scale in the city's everyday mobility. The analysis aimed at testing whether significant efforts on improving local conditions and fostering local mobility would help to improve social exclusion and transport disadvantage situations by alleviating the need of motorized and long-distance transport. Unlike most traditional analysis, proximity is not defined by Euclidian distance but instead using travel and modal choice variables. Results show the relevance of socioeconomic variables at determining travel behaviors as well as the importance of local accessibility for social groups in situations of transport disadvantage.     

Accelerating sustainable mobility and land-use transitions in rapidly growing cities: Identifying common patterns and enabling factors

Urban growth has been increasing rapidly across the globe, in particular in low and middle-income developing countries. As city populations and GDP per capita rise exponentially, cities tend to experience similar challenges related to urban development and transport/mobility.One of the most problematic issues emerges when urban growth drives car-oriented urban development. This is characterised by a range of unsustainable patterns such as low-density development, urban sprawl, lack of plans and infrastructure to accommodate collective transport and active travel, and significant efforts and investments to meet the demand for private motorised vehicle use. For emergent cities, the risk is that these developments lead to highly inefficient, unhealthy and unsustainable urban systems that are difficult to remedy.This paper aims to identify recurrent governance and policy factors across sectors, as well as macro factors, that tend to contribute to car-dependent urban mobility systems in rapidly growing cities. It draws on qualitative and quantitative research findings from five under-researched Eastern European and Middle Eastern cities: Tallinn, Bucharest, Skopje, Adana and Amman. Data examining the evolution of urban mobility in these cities were collected as part of the Horizon2020 EU funded project CREATE.The paper investigates the extent to which car-dependent urban development processes can be avoided in rapidly growing cities, to support transitions towards liveable and sustainable cities. Finally, it provides policy recommendations targeting growing cities with low levels of car-use, in particular in Sub-Saharan Africa. It highlights the importance of acting swiftly to achieve targets such as the Sustainable Development Goals, the New Urban Agenda or the Paris Agreement, by supporting policies fostering efficient, sustainable and inclusive urban mobility and land-use across sectors and levels of governance.     

Evaluation of the spatial pattern of logistics facilities using urban logistics land-use and traffic simulator

Despite the growing research interests on the spatial restructuring of logistics facilities that occurred in many cities around the world, the relationship between the spatial pattern of logistics land use and the level of externalities is far from being elucidated. We use the Urban Logistics Land-use and Traffic Simulator (ULLTRA-SIM), developed for the Tokyo Metropolitan Area, to evaluate the level of externalities that accompany different spatial distribution patterns of logistics facilities. The ULLTRA-SIM takes a novel approach to analyze the urban freight impacts through the simulations of logistics facility locations, urban logistics chains, and truck flow. The results indicate that, while the moderate concentration and deconcentration of logistics facilities do not significantly affect the level of externalities, scarcity of logistics facilities in or near the high demand locations exacerbates negative externalities. Also, the results of the simulations underscore the need for rigorous analysis in order to reduce negative externalities through logistics land use policies.     

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.     

Where to park? A behavioural comparison of bus Park and Ride and city centre car park usage in Bath,UK

Integrating car parking facilities with public transport in Park and Ride (P&R) facilities has the potential to shorten car trips, contributing to more sustainable mobility. There is an ongoing debate about the actual effects of P&R on the transport system at the subregional level. A key issue is the relative attractiveness of city centre car parks (CCCP), P&R and public transport. The paper presents the findings of a comparative empirical case-study based on a field survey of CCCP and P&R users conducted in the city of Bath, UK. Spatial and statistical analyses are applied. Radial distance to parking, availability of P&R sites in the direction of travel, gender, age, income and party-size are found to be important factors in a binary logistic regression model, explaining the revealed-preference of parking type. Stated analysis of foregone parking alternatives suggests more use of public transport and walking/cycling would likely occur without first-best parking alternatives. The policy implications and possible planning alternatives to P&R at the urban fringes for achieving greater sustainability goals are also discussed.     

Regional transport and its association with tuberculosis in the Shandong province of China, 2009–2011

Human mobility has played a major role in the spread of infectious diseases such as tuberculosis (TB) through transportation; however, its pattern and mechanism have remained unclear. This study used transport networks as a proxy for human mobility to generate the spatial process of TB incidence. It examined the association between TB incidence and four types of transport networks at the provincial level: provincial roads, national roads, highways, and railways. Geographical information systems and geospatial analysis were used to examine the spatial distribution of 2217 smear-positive TB cases reported between 2009 and 2011 in the Shandong province. The study involved factors such as population density and elevation difference in conjunction with the types of transport networks to predict the disease occurrence in space. It identified spatial clusters of TB incidence linked not only with transport networks of the regions but also differentiated by elevation. Our research findings provide evidence of targeting populous regions with well-connected transport networks for effective surveillance and control of TB transmission in Shandong.     

Does low income translate into lower mobility? An investigation of activity space in Hong Kong between 2002 and 2011

Daily mobility of disadvantaged social groups, particularly low-income people, has gained increasing interest since the daily life of these people may encounter significant constraints that lead to certain social issues such as social exclusion and segregation. The concept and measure of activity space have been applied to measure the spatial barriers and inequalities faced by the low-income group in their daily life. However, research on how the daily mobility of different social strata has evolved over a longer period in parallel with urban development has been very limited. This study aims to address these gaps by investigating the activity space of the low-income group in comparison with other income groups in Hong Kong from 2002 to 2011, a period when several subway lines were opened. Four indicators were employed to capture the spatial extent and diversity of activity space. Propensity score matching was used to compare the activity space and mobility of the low-income group with those of the below-average and higher-income groups, while controlling for several confounding factors. The findings indicate that the activity space of the low-income people has not improved over the decade, despite some marked expansion of public transport infrastructure and urban development. In addition, a persistent gap in activity space between the low-income group and other income groups has remained stark in both urban areas and the new towns. Policy recommendations are put forward with a view to improving the daily mobility of the low-income group, with avenues for future research identified as well.     

Emerging cycling policy in Moscow,Russia: The role of international policy transfer

Over the past four decades, commuter cycling has become a planning issue in cities that did not have established cycling cultures. This category includes post-Socialist cities with recent and strong automobility systems and limited cycling planning experiences. This article seeks to demonstrate how transfer of policy ideas from other contexts has contributed to the emergence of cycling policies in the largest post-Socialist city, Moscow, Russia, in the mid 2000s - 2016. Policy transfer means the diverse processes of acquiring policy ideas from other planning contexts and adapting this knowledge to shape local policies. The article is based on the results of a study that combined policy transfer questions with policy ethnography methodology that entailed prolonged field work and interviews with diverse policy actors and beneficiaries. This article aims to answer a question: How did policy learning, transfer and translation contribute to the emergence of Moscow's cycling policy? The article concludes that policy transfer facilitated cycling planning in Moscow by providing fast solutions, informing and legitimizing policy decisions, and temporarily leveraging cyclists' advocacy efforts. However, policy learning and transfer do not guarantee acceptance or successful implementation of policies. Integration of cycling into transport policies depends on an interplay of local institutional, political, and socio-spatial factors that influence decision-making. Constraints to implementing cycling policies include a peculiar car-culture, technocratic planning with a significant role of state actors and other elite groups, and insufficient opportunities for Moscow's cycling community to influence policy-making. These findings contribute to the transport policy and geography literature by exploring the role of policy transfer in cycling planning and by focusing on a less known transport policy context: post-Socialist cities outside the European Union.
