Addressing Climate Change in Transport: Volume 2 : Pathway to Resilient Transport
(World Bank, Hanoi, 2019-09-01)Climate change is set to have profound effects on Vietnam’s development. With nearly sixty percent of its land area and seventy percent of population at risk of multiple natural hazards, Vietnam globally is among the most vulnerable countries to both chronic and extreme events. At the same time, as Vietnam’s economy grows, the country is becoming a significant emitter of greenhouse gases. While Vietnam’s absolute volume of emissions is still small compared to that of larger and richer countries, emissions are growing rapidly and disproportionate to its economy size. The transport sector plays a critical role in these recent trends. This study aims to set out a vision and strategy for climate-smart transport, in order to minimize the carbon footprint of the sector while ensuring its resilience against future risks. The analytical findings and recommendations are presented in two volumes of the report. The first volume provides how Vietnam can reduce its carbon emissions by employing a mix of diverse policies and investments, under varying levels of ambition and resources. The second volume provides a methodological framework to analyze network criticality and vulnerability, and to prioritize investments to enhance resilience. -

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. -

Review of Performance Based Contracting in the Road Sector : Phase 2. Review of Training Materials and Resources
(World Bank, Washington, DC, 2014-03)Performance Based Contracts (PBC's) are not new to the transport sector, with many variants in use in different countries for close to two decades. International lending institutions, such as the World Bank, have played a significant role in pushing PBCs into developing nations as part of loan assistance packages. However, there has been a tendency for a 'one-size-fits-all' approach to the implementation, with the result being a variation in the success of any implemented PBCs, as well as a significant proportion of the proposed PBCs not making it to the contract award stage. To address these issues, the World Bank has commissioned a review of performance based contracting in the road sector (contract number 7158253) led by Opus International Consultants Limited. Outputs from the project to date include: phase one report covering the review of previous PBCs (Opus 2011); a guide for the application of PBCs (Opus, 2012a); points to guide Bank implementation of PBCs (Opus, 2012b); and this review of existing training materials and resources. -

A Guide to Delivering Good Asset Management in the Road Sector through Performance Based Contracting
(World Bank, Washington, DC, 2014-03)The road sector represents a significant asset to any country both in terms of the physical cost to build it, and the social and economic benefits that it facilitates. Good asset management in the road sector is about obtaining the desired benefits at the least whole-of-life cost, and it is therefore natural to seek to implement a robust asset management approach on what is typically a nation's largest asset. Implementation of performance based contracting (PBC) necessitates the identification of many of the cornerstones to asset management, such as knowing the asset, managing risks, and determining the sustainable level of service for the funds available. The aim of this guide is to help understand: (1) what asset management is and why it is important; (2) how performance based contracting delivers good asset management; and (3) the issues and challenges associated with successful implementation of a performance based contract. This guide is focused on PBCs with a significant contract term. This guide draws extensively on the report, review of performance based contracting in the road sector, phase 1: tasks 1 to 6 which examined 35 projects across 27 countries, combined with the knowledge of an international project team. -

Review of Performance Based Contracting in the Road Sector : Phase 1
(World Bank, Washington, DC, 2014-03)There has been a tendency for a one-size-fits-all approach to the implementation, with the result being a variation in the success of any implemented performance based contracts (PBCs), as well as a significant proportion of the PBCs not making it to the contract award stage. To address these issues, the World Bank (WB) has commissioned a review of PBC in the road sector. PBC involves a significant shift away from more traditional approaches to the delivery and maintenance of road infrastructure and associated services by departing from the client's having responsibility for the design and supervision of construction and maintenance activities, to focus upon the key outcomes that the client wishes to achieve. There are two objectives for this study including: (1) to produce a strategy that will guide the WB's future engagements in PBC projects; and (2) to improve the WB's service to clients by offering a variety of PBC options, to suit different operating conditions and client needs. The report details phase one, review and synthesis of existing practices and its following six tasks: task 1, taking stock of various types of PBC projects; task 2, defining various types of PBC methodologies; task 3, outlining PBC's strengths and weaknesses; task 4, clarifying both various types of PBCs and federation internationale des ingenieurs-conseil (FIDIC)-type (input and bill of quantities) contracts; task 5, discriminating between successful and less successful factors of PBC projects; and task 6, developing a work program on how to move the second phase forward. -

Improving Accessibility to Transport for People with Limited Mobility : A Practical Guidance Note
(Washington, DC, 2013-05)This document aims to provide practical guidance on how best to include consideration of accessibility for People with Limited Mobility (PLM). While disabled people are a primary focus, the definition of PLM considered within this guidance note therefore also encompasses this broader range of users with mobility constraints and needs. Barriers to addressing the needs of PLM are often a product of a lack of information for transport professionals and facility designers, combined with limited resources. To assist client countries with implementing the principles and binding obligations of the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD), it is clear that World Bank Task Team Leaders (TTLs) need to understand how to build in accessibility for disabled people in the design and implementation of transport projects. This guidance note therefore aims to aid World Bank TTLs when specifying and managing Bank funded transport projects in order to improve the accessibility of transport systems for PLM. It is intended to serve primarily as a point of reference for TTLs on how to include, and improve; the accessibility of PLM in Bank supported transport operations, as well as being useful for other organizations and government agencies. Following this introductory chapter, chapter two provides concise technical descriptions of different transport accessibility measures, of their costs, benefits and implementation issues, and of relevant standards and sources of further detailed design guidance. In chapter three these accessibility features are gathered into ranked lists to which TTLs may refer in order to see which measures represent low cost options, and those which are likely to have the best benefit/cost relationships. Chapter four sets out information on relevant regulatory and institutional framework issues. Chapter five summarizes potential funding sources and mechanisms for providing accessibility improvements for people with limited mobility. Finally, chapter six (operational road map) provides guidance on the process for designing accessibility into World Bank transport projects. -

Road Freight in Central America: Five Explanations to High Costs of Service Provision
(World Bank, Washington, DC, 2012-06)An efficient system to transport goods domestically and internationally is a key element of the logistics chain. Road freight transport has a direct impact on poverty as it employs millions of people and generates a significant portion of Gross Domestic Product, or GDP, especially in low and middle-income countries. Trucking is the primary form of transportation for domestic, trans-border, and international cargo, in Central America. Road freight transport is now vital to production, distribution, and mobilization, driving economic, social, and environmental progress. In short, trucking is the backbone of economies around the world. In the past 20 years, the industry has advanced as technology has improved communication, management, productivity, including vehicle efficiency. Their objective in doing so is to expand markets, generate wealth on the basis of efficient specialization, introduce competition, and lower costs for production, distribution, services, and research and development. When road freight transport services are efficient, they support these objectives; when they are not they act as nontariff barriers to trade, creating delays, raising costs, worsening congestion and pollution. Such barriers prolong and destabilize delivery schedules, hinder 'just in time' inventory management and industrial processes, and impede the efficient combination of factors of production. -

Transport Emissions and Savings in Health Costs
(World Bank, Washington, DC, 2012)The paper aims to provide the basis for an estimation equation and will focus on the relation between transport emissions and air quality in an urban environment. This is directly related to the fact that most health impacts are related to local air quality levels. The aim of the paper is to create an understanding of the factors that play a role in the causal relation between transport emissions and health effects and provides approximations from existing studies that can be used to assess these health impacts and related costs. The paper focuses on the translation of air pollution levels into health impacts and health costs. The overall structure of the paper follows the two key steps and elaborates on the inherent challenges: (1) identify and measure the health effects of air pollution, and (2) to estimate the costs of the health effects. The paper is divided into four chapters: chapter one is introduction- outlining the goals and background to the project; chapter two gives impacts of air pollution from transport on health; chapter three presents valuation of health impacts- reviews the literature on how to value the impacts on health associated with air pollution; and chapter four gives guidelines for calculating the health effects of air pollution from traffic. -

Sustainability of Transport Projects: Toolkit
(World Bank, Washington, DC, 2012)This report is the output of the finalize toolkit phase (phase three) for the project sustainability toolkit for transport projects. The overall objective, as defined in the terms of reference, is 'to make development projects more sustainable by reducing the risk of failure of projects attaining their long-term development goals and enhance the prospects for their sustained impact on development ensuring that there is local commitment to longer-term buy-in'. The main deliverable of the project is a project sustainability toolkit, of which this report outlines the final version. This toolkit helps to gauge the potential for the project to be sustainable into the long-term and provide advice to help overcome common barriers to the successful development and implementation of projects. The guidance covers the expected opportunities and constraints related to sustainability. The toolkit is intended to reduce the risk of project failure in terms of sustainable development and enable recipient country clients to incorporate core sustainability principles into transport projects at every stage of project planning, design and delivery. This will improve the prospects for longer-term sustainability and will enhance the long-term impacts of development projects. Task Team Leaders (TTL's) will benefit from additional evidence that supports investments intended to consolidate long-term development, and borrowers will benefit from projects with improved and demonstrable longer-term beneficial impact. The toolkit provides general advice for transport sector investments and is not modally specific. Information on the sub-components of the key sustainability principles has not been included since it was considered that this did not add value or further understanding of the issues. -

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.
