Abstract
The Highway Development and Management Model (HDM-4) is a software system for evaluating options for investing in road transport infrastructure. Worldwide, the HDM-4 model is most commonly used as a basis for feasibility studies, in which a road project is evaluated in terms of its economic viability. A more comprehensive type of evaluation based on HDM-4 is a network evaluation, which assesses an entire road network to help decision makers in their strategic planning of road investments and/or the definition of a rational road works program, with or without budget constraints. A network economic evaluation is the most challenging use of the model, but the effort is well justified given the potential savings to be achieved on transport costs by comparing various project alternatives and performing an optimization under budget constraints. This technical note presents the author's experience applying HDM-4 and its predecessor, the Highway Design and Maintenance Standards Model (HDM-III), to road network strategic planning evaluations in developing countries, with the objective of providing recommendations and tools to the readers who are involved in strategic planning activities. The purpose of the evaluations, the methodology itself, the input requirements, the challenges, and the presentation of results to decision makers are each reviewed in turn.

Publication Improving the Sustainability of Road Management and Financing in Armenia(World Bank, 2011-10-13)The objectives of this study are: 1) to identify weaknesses and challenges confronting the sustainability of road maintenance and rehabilitation management; 2) to determine to what extent these are linked to particular institutional and financing arrangements; and 3) to assess how these factors can be resolved. The Study makes a series of recommendations aimed at improving the sustainability of the management and financing of the road sector. First, the study provides an overview of the road sector and the condition of the road network. Then it turns to a review of road management and financing in Georgia. The study reviews the current institutional and technical arrangements, with regard to the ability to effectively plan, design, construct, and maintain the road network. It gives particular emphasis to the implementation arrangements for the road sector, including: budgeting; management and resources; technical standards in use; quality assurance and education/training; and provision of maintenance for different road classes. The findings of the study are timely. It is hoped that they will inform a policy discussion on the need to raise expenditures on the maintenance of the road network, and provide a roadmap for financing these needs in an efficient, cost-effective manner.Publication Road Projects Cost Benefit Analysis(World Bank, Washington, DC, 2010)Six projects from six countries were selected as the cases for detailed analysis in this study. They are from Argentina, Botswana, India, Kenya, Lao PDR and Paraguay, representing a wide range of geographical distribution. Also, the extent of the effect of economic downturn which these countries experienced ranges a wide variety. In an economic downturn, uncertainties increase with many inputs of road projects Cost Benefit Analysis (CBA), including fuel prices, levels of demand, investment costs and maintenance availability. Also, important parameters of project evaluation such as discount rate and value of time need to be more carefully scrutinized. Therefore, it is very important for the developing countries to have good understanding about the effects of the variability of these inputs/parameters on project viability and the ranking of road investments. It is a role of the developing agencies to conduct a systematic analysis of these effects and disseminate the findings and knowledge obtained. The objective of the study is to obtain insights regarding the effects of varying inputs and parameters on the viability of road projects through case studies using Highway Development and Management Model (HDM-4), thereby to facilitate the formulation and implementation of road projects that increase the welfare of the society under the environment of increased uncertainty in an economic downturn. The results of the study will be summarized in a transport note as a discrete knowledge product and disseminated among various stakeholders including developing agencies staff, government officials and donor communities. To assess the effects of increased uncertainty with inputs of cost benefit analysis on the economic viability of road projects, this study first investigated the range of variability of the inputs for the six selected projects/countries. It was found that the variability ranges differ by country reflecting the degree of decrease in transport demand and relative change in factor prices due to economic downturn.Publication Rethinking Infrastructure Delivery: Case Study of a Green, Inclusive, and Cost-effective Road Program in Nicaragua(World Bank, Washington, DC, 2014-06)This paper presents a development case study on alternative thinking in rural infrastructure delivery. Delivery in this case is achieved in a manner that advances the green growth, social inclusion and cost-effectiveness agendas. The need for green and inclusive approaches in reaching development goals cannot be overstated. At the same time, the use of public funds should ensure value for money and stretch government resources as far as they can go. Inclusion refers to the empowerment of all citizens to participate in, and benefit from the development process, removing barriers against those who are often excluded. The use of a community development approach is presented in this paper to demonstrate how this has been achieved on large scale and in a cost-effective way without compromising quality or timing. Heightened roles and responsibilities are conferred to the local target authorities and populations in this infrastructure delivery approach, and this experience is presented as a best practice that could be emulated in similar development work. On the technical front, most road infrastructure delivery in many countries is heavily mechanized and undertaken using default asphalt surfacing. This paper presents the adoption of an alternative and green paving material that is also cost-effective at the secondary rural road level.Publication Improving the Sustainability of Road Management and Financing in Azerbaijan(World Bank, Washington, DC, 2011-10-13)A well-maintained road network that provides the level of service required by road-users is an important element of Azerbaijan's development strategy to accelerate economic growth and reduce poverty. As part of this strategy, the Government of Azerbaijan (Government) has undertaken major capital improvements on the major arterial road network. However, the secondary and local roads continue to be underfunded, and a large rehabilitation backlog has been accumulating in recent years. Deferred maintenance leads to a future burden of more expensive rehabilitation and road reconstruction: for every US$1 in deferred maintenance, there is an associated US$4 cost to road-users. To avoid such a scenario, the Government needs: (i) to devise an institutional and financing framework that provides adequate funding for maintenance and rehabilitation; and (ii) to finance capital improvements on key priority roads. The objectives of this study are: (i) to identify the weaknesses and challenges confronting the sustainability of road maintenance and rehabilitation; (ii) to determine to what extent these factors are linked to particular institutional and financing arrangements; and (iii) to assess how these factors can be resolved. The study makes a series of recommendations aimed at improving the management and financing of the road sector in Azerbaijan.Publication Performance-Based Road Rehabilitation and Maintenance Contracts in Argentina : A Review of Fifteen Years of Experience (1996-2010)(World Bank, Washington, DC, 2011-09)The road sector is the dominant mode of transport in Argentina carrying nearly 80 percent of total freight volume. The road network has a total length of about 630,000 km (11 percent paved), divided in three administrative levels: national, provincial, and municipal. However, more than 70 percent of total traffic volumes are concentrated on the paved national and provincial network, with the municipal network consisting of unpaved roads, access roads to farms and feeder roads with very low traffic volumes. A survey carried out in 1992 confirmed that only 44 percent of the national paved network was in good condition, with a high 35 percent of roads in poor condition. Rehabilitation works for the non-concessioned portion were contracted to the private sector under the traditional ad-measurement type or unit price-based system while maintenance activities continued to be carried out by force-account. In 1993 a loan from the World Bank was approved to finance, for the first time, high priority rehabilitation and maintenance works on the non-concessioned paved network, leading to the development of a long-term maintenance strategy based on the gradual expansion of performance-based contracts, a modality that is currently being replicated in other countries around the world. This paper is organized as follows: chapter one presents the national road network of Argentina; chapter two gives origins and definition of the Contrato de Recuperacion y Mantenimiento (CREMA) contracts; chapter three gives evolution in the procurement and the design standards of the CREMA; chapter four presents the market's response to the CREMA system; chapter five presents impact of the CREMA on the condition of the national road network; chapter six deals with cost effectiveness of the CREMA system; chapter seven presents Bank's strategy and role in the road sector in Argentina; and chapter eight gives lessons learned.

Publication Crime and Violence in Central America : A Development Challenge - Main Report(World Bank, 2011-01-01)Crime and violence are now a key development issue for Central American countries. In three nations El Salvador, Guatemala, and Honduras crime rates are among the top five in Latin America. This report argues that successful strategies require actions along multiple fronts, combining prevention and criminal justice reform, together with regional approaches in the areas of drug trafficking and firearms. It also argues that interventions should be evidence based, starting with a clear understanding of the risk factors involved and ending with a careful evaluation of how any planned action might affect future options. In addition, the design of national crime reduction plans and the establishment of national cross-sectoral crime commissions are important steps to coordinate the actions of different government branches, ease cross-sectoral collaboration and prioritize resource allocation. Of equal importance is the fact that national plans offer a vehicle for the involvement of civil society organizations, in which much of the expertise in violence prevention and rehabilitation resides. Prevention efforts need to be complemented by effective law enforcement. The required reforms are no longer primarily legislative in nature because all six countries have advanced toward more transparent adversarial criminal procedures. The second-generation reforms should instead help deliver on the promises of previous reforms by: (i) strengthening key institutions and improving the quality and timeliness of the services they provide to citizens; (ii) improving efficiency and effectiveness while respecting due process and human rights; (iii) ensuring accountability and addressing corruption; (iv) increasing inter-agency collaboration; and (v) improving access to justice, especially for poor and disenfranchised groups. Specific interventions reviewed in the report include: information systems and performance indicators as a prerequisite to improve inter-institutional coordination and information sharing mechanisms; an internal overhaul of court administration and case management to create rapid reaction, one-stop shops; the strengthening of entities that provide legal counseling to the poor and to women; and the promotion of alternative dispute-resolution mechanisms and the implementation of community policing programs.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 The Mexican Social Protection System in Health(World Bank, Washington DC, 2013-01)With a population of 113 million and a per-capita Gross Domestic Product, or GDP of US$10,064 (current U.S. dollars), Mexico is one of the largest and highest-income countries in Latin America and the Caribbean (LAC). The country has benefited from sustained economic growth during the last decade, which was temporarily interrupted by the financial and economic crisis. Real GDP is projected to grow 3.8 percent and 3.6 percent in 2012 and 2013, respectively (International Monetary Fund, or IMF 2012). Despite this growth, poverty in the country remains high; with half of the population living below the national poverty line. The country is also highly heterogeneous, with large socioeconomic differences across states and across urban and rural areas. In 2010, while the extreme poverty ratio in the Federal District and the states of Colima and Nuevo Leon was below 3 percent, in Chiapas, Guerrero, and Oaxaca it was 25 percent or higher. These large regional differences are also found in other indicators of well-being, such as years of schooling, housing conditions, and access to social services. This case study assesses key features and achievements of the Social Protection System in Health (Sistema de Proteccion Social en Salud) in Mexico, and particularly of its main pillar, Popular Health Insurance (Seguro Popular, PHI). It analyzes the contribution of this policy to the establishment and implementation of universal health coverage in Mexico. In 2003, with the reform of the General Health Law, the PHI was institutionalized as a subsidized health insurance scheme open to the population not covered by the social security schemes. Today, the PHI covers all of its intended affiliates, about 52 million peoplePublication Guide to the Debt Management Performance Assessment Tool(Washington, DC, 2008-02-05)The purpose of this document is to provide guidance and supplemental information to assist with country assessments of debt management performance, using the Debt Management Performance Assessment (DeMPA) tool. The DeMPA is a methodology used for assessing public debt management performance through a comprehensive set of 15 performance indicators spanning the full range of government Debt Management (DeM) functions. It is based on the principles set out in the International Monetary Fund (IMF) and World Bank guidelines for public debt management, initially published in 2001 and updated in 2003. It is modeled after the Public Expenditure and Financial Accountability (PEFA) framework for performance measurement of public financial management. The DeMPA has been designed to be a user-friendly tool to undertake an assessment of the strengths and weaknesses in government DeM practices. This guide provides additional background and supporting information so that a no specialist in the area of debt management may undertake a country assessment effectively. The guide can be used by assessors in preparing for and undertaking an assessment. It is particularly useful for understanding the rationale for the inclusion of the indicators, the scoring methodology, and the list of supporting documents or evidence required, and the questions that could be asked for the assessment.Publication Business Ready 2024(Washington, DC: World Bank, 2024-10-03)Business Ready (B-READY) is a new World Bank Group corporate flagship report that evaluates the business and investment climate worldwide. It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.
