Abstract
A key goal of urban transportation planning is to provide people with access to a greater number of opportunities for interaction with people and places. Measures of accessibility are gaining attention globally for use in planning, yet few studies measure accessibility in cities in low-income countries, and even fewer incorporate semi-formal bus systems, also called paratransit. Drawing on rich datasets available for Nairobi, Kenya this analysis quantifies place-based accessibility for walking, paratransit, and driving using three different measures: a mobility measure quantifying how many other locations in Nairobi can be reached in 60 min, a contour measure quantifying the number of health facilities that can be reached in 60 min, and a gravity measure quantifying the number of health facilities weighted by a time-decay function. Health facilities are used because they are an essential service that people need physical access to and as a representation of the spatial distribution of activities more broadly. The findings show that place-based accessibility is highest for driving, then paratransit, then walking, and that there are high levels of access to health facilities near the Central Business District (CBD) for all modes. Additionally, paratransit accessibility is comparatively better in the contour and gravity measures, which may mean that paratransit is efficiently providing access based on the spatial distribution of services. The contour measure results are also compared across different residential levels, which are grouped based on neighborhood characteristics and ordered by income. Counterintuitively, the wealthiest areas have very low levels of place-based accessibility for all modes, while poor areas have comparatively better walking access to health facilities. Interestingly, the medium low residential level, characterized in part by tenement apartment buildings, has significantly higher accessibility than other residential types. One way to reduce inequality in access across income groups is to increase spatial accessibility for the modes used by low- and middle-income households, for example with policies that prioritize public transport and non-motorized travel, integrate paratransit with land use development, and provide safe, efficient, and affordable options.

Publication Cities on the Move : A World Bank Urban Transport Strategy Review(Washington, DC, 2002-08)The report's objectives are i) to better understand the nature and magnitude of urban transport problems, particularly in respect of the poor, and ii) to articulate a strategy by which the World Bank and other agencies can assist national and city governments to address these problems. The first part of the report considers how urban transport can be used as an instrument of urban development and poverty reduction. Chapter 2 discusses how transport reduces poverty. Chapter 3 examines how urban transport policies can be focused more specifically on meeting the needs of the poor but touches on other transport related aspects of the quality of life of poor people. Chapter 4 considers the urban environment, focusing on air pollution to which the poor are particularly vulnerable, while Chapter 5 considers problems of personal safety and security. The second part of the report considers how the objectives can be pursued by using a range of instruments. Chapter 6 considers the provision and management of road infrastructure. Chapter 7 discusses road based public transport, including the role of the informal sector. Chapter 8 considers the role and limitations of mass transit. Chapter 9 pays special attention to non-motorized transport. Chapter 10 raises the issues of pricing and financing, and Chapter 11, looks at institutional arrangements. Finally, Chapter 12 discusses the implications for the instruments and lending strategies of the Bank.Publication Understanding the Emerging Role of Motorcycles in African Cities : A Political Economy Perspective(World Bank, Washington, DC, 2011-04)A decline in organized public transport systems has led to rapid growth in non-conventional means of public transport, initially provided by minibuses and shared taxi/vans, and more recently by commercial motorcycles. Unlike cities in South and East Asia, ownership and use of motorized two-wheelers as a personalized vehicle is very small in sub-Saharan cities. However, over the past decade there has been a significant growth in the use of motorcycles as a commercial public transport mode. While offering certain transport advantages in the form of easy maneuverability, ability to travel on poor roads, and demand responsiveness, commercial motorcycle service growth has also led to an increase in road accidents, traffic management problems, pervasive noise and increases in local air pollution and greenhouse gas emissions. Government efforts to regulate the market have had the contrary impact of compounding the problem by distorting market structures. The growth in the use of commercial motorcycles has also dispelled one of the commonly held illusions: fare controls in the public bus market are often justified to support affordability for a vast majority of low income population; however, commercial motorcycles are more expensive than the lowest bus fares, but are increasingly being patronized by the poor due to the inadequacy of bus services. This paper attempts to evaluate the commercial motorcycle mode used in the three cities of Douala, Lagos, and Kampala, based on their political economy context in order to draw general conclusions of value throughout Africa and the rest of the developing world. The evaluation underscores the linkages between governance failure and weak sector performance and highlights the need to adapt policy instruments to local political and economic context. Central to discussion is the necessity to develop a participation framework driven by open communications across a wide spectrum of stakeholders.Publication Transforming Cities with Transit : Transit and Land-Use Integration for Sustainable Urban Development(Washington, DC: World Bank, 2013-01-03)This study explores the complex process of transit and land-use integration in rapidly growing cities in developing countries. It first identifies barriers to and opportunities for effective coordination of transit infrastructure and urban development. It then recommends a set of policies and implementation measures for overcoming these barriers and exploiting these opportunities. Well-integrated transit and land development create urban forms and spaces that reduce the need for travel by private motorized vehicles. Areas with good access to public transit and well-designed urban spaces that are walkable and bikeable become highly attractive places for people to live, work, learn, play, and interact. Such environments enhance a city's economic competitiveness, reduce local pollution and global greenhouse gas emissions, and promote inclusive development. These goals are at the heart of transit-oriented development (TOD), an urban form that is increasingly important to sustainable urban futures. This book uses a case study approach. It draws lessons from global best-case examples of transit-oriented metropolises that have direct relevance to cities in developing countries and elsewhere that are currently investing in bus rapid transit (BRT) and other high-capacity transit systems. It also reports the results of two original in-depth case studies of rapidly growing and motorizing cities that introduced extended BRT systems: Ahmedabad, India and Bogota, Colombia. Two shorter case studies enrich the understanding of factors that are critical to transforming cities with transit.Publication Mongolia Trade and Transport Facilitation Action Plan(Washington, DC, 2009-01-20)This report develops and expand on the Trade Facilitation and Logistics Development Strategy Report, published in December 2006. This report employs a supply chain perspective which focuses on the trade and transportation needs of the products and supply chains assessed. These specific needs are then compared with the trade facilitation services available, the gaps between these and the needs identified, recommendations made for closing the gaps. Three export and three import products/product groups have been chosen for analysis, for the highest export growthpotential. Given the recent dramatic decline in the market price of minerals and the drop in demand for them, diversification of Mongolia's economy and international trade has assumed renewed importance. In this review we have combined attention to traditional exports as support for diversification of trade, while not ignoring the export of minerals and import of mining equipment as these will continue to be important.Publication Transport Strategy to Improve Accessibility in Developing Countries(World Bank, Washington, DC, 2004-05-01)In developing countries disabled people and the elderly are more likely to be among the poor. Moreover, exclusion increases the costs associated with disability to constrain disabled people from breaking out of poverty. Improved access and mobility are important factors in reducing poverty and can facilitate the participation of people with disabilities in economic, social, and political processes. Many countries have legislation requiring that these challenges be addressed but effective responses are generally very limited. Action to improve the situation is constrained by the serious shortage of data on the access and mobility needs of disabled and elderly people as well as by resource constraints. This paper outlines guidance for addressing the access and mobility needs of disabled and elderly people in the context of the World Bank's mission to reduce poverty and discusses the main challenges for providing inclusive transport. It draws attention to opportunities to learn from transport interventions and to current research. The paper describes the main activities being fostered by the transport sector in the World Bank. These aim to raise awareness of proven good practice in setting policies and strategies.

Publication World Development Report 2008(Washington, DC, 2007)The world's demand for food is expected to double within the next 50 years, while the natural resources that sustain agriculture will become increasingly scarce, degraded, and vulnerable to the effects of climate change. In many poor countries, agriculture accounts for at least 40 percent of GDP and 80 percent of employment. At the same time, about 70 percent of the world's poor live in rural areas and most depend on agriculture for their livelihoods. World Development Report 2008 seeks to assess where, when, and how agriculture can be an effective instrument for economic development, especially development that favors the poor. It examines several broad questions: How has agriculture changed in developing countries in the past 20 years? What are the important new challenges and opportunities for agriculture? Which new sources of agricultural growth can be captured cost effectively in particular in poor countries with large agricultural sectors as in Africa? How can agricultural growth be made more effective for poverty reduction? How can governments facilitate the transition of large populations out of agriculture, without simply transferring the burden of rural poverty to urban areas? How can the natural resource endowment for agriculture be protected? How can agriculture's negative environmental effects be contained? This year's report marks the 30th year the World Bank has been publishing the World Development Report.Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.Publication World Development Report 1987(New York: Oxford University Press, 1987)This report, consisting of two parts, is the tenth in the annual series assessing development issues. Part I reviews recent trends in the world economy and their implications for the future prospects of developing countries. It stresses that better economic performance is possible in both industrial and developing countries, provided the commitment to economic policy reforms is maintained and reinforced. In regard to the external debt issues, the report argues for strengthened cooperation among industrial countries in the sphere of macroeconomic policy to promote smooth adjustment to the imbalances caused by external payments (in developing countries). Part II reviews and evaluates the varied experience with government policies in support of industrialization. Emphasis is placed on policies which affect both the efficiency and sustainability of industrial transformation, especially in the sphere of foreign trade. The report finds that developing countries which followed policies that promoted the integration of their industrial sector into the international economy through trade have fared better than those which insulated themselves from international competition.Publication Digital Africa(Washington, DC: World Bank, 2023-03-13)All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.Publication World Development Report 2005(World Bank, 2004)Firms and entrepreneurs of all types from microenterprises to multinationals play a central role in growth and poverty reduction. Their investment decisions drive job creation, the availability and affordability of goods and services for consumers, and the tax revenues governments can draw on to fund health, education, and other services. Their contribution depends largely on the way governments shape the investment climate in each location through the protection of property rights, regulation and taxation, strategies for providing infrastructure, interventions in finance and labor markets, and broader governance features such as corruption. The World Development Report 2005 argues that improving the investment climates of their societies should be a top priority for governments. Drawing on surveys of nearly 30,000 firms in 53 developing countries, country case studies, and other new research, the Report explores questions such as: What are the key features of a good investment climate, and how do they influence growth and poverty? What can governments do to improve their investment climates, and how can they go about tackling such a broad agenda? What has been learned about good practice in each of the main areas of the investment climate? What role might selective interventions and international arrangements play in improving the investment climate? What can the international community do to help developing countries improve the investment climates of their societies? In addition to detailed chapters exploring these and related issues, the Report contains selected data from the World Bank's new program of Investment Climate Surveys, the Bank's Doing Business Project, and World Development Indicators 2004‹an appendix of economic and social data for over 200 countries. This Report offers practical insights for policymakers, executives, scholars, and all those with an interest in economic development.
