Addis Ababa Sidewalk Safety and Improvement Study: Project Report
(Washington, DC: World Bank, 2022-02-28) World Bank
Walking is a predominant mode of travel in Addis Ababa representing more than half of the daily trips. The mild climate in Addis Ababa is conducive for this healthy and green mode of transport. However, sidewalks are often narrow, uneven, obstructed, or non-existent, causing discomfort and road safety risks to the most vulnerable road users: pedestrians. Studies done by the WHO and the Government showed that AA has disproportionately high pedestrian fatalities. The World Bank study on Addis Ababa Sidewalk Safety and Improvement takes the approach of integrating digital technology and Urban Inventory in sidewalk surveys, applies the Global Walkability Index in sidewalk assessments, and adapts the global best practice to the local context. The Project Report diagnoses sidewalk conditions and walkability in a Light Rail Corridor, proposes strategies and formulates low-hanging fruit actions to redress the sidewalk deficiencies, and bridges the connection between pedestrians, sidewalks, urban design, and road safety through an integrated multi-sector approach.
Implementation of Innovative Bridge Technologies: Technical Guidance Note
(Washington, DC, 2022) World Bank
Bridges are critical components in the transport network and serve as vital links significantly contributing to social connection and economic production across the Pacific. Bridges are intrinsically exposed to natural hazards and impacted by climate change. Delays associated with the ongoing maintenance of bridges can also put additional strain on this infrastructure and leave them more susceptible to damage. Collectively, these issues serve as a catalyst to the continuing efforts of donors to support the research, exploration, development, and implementation of bridge solutions that consider a local context. This technical guidance note highlights the methodology and lessons learned from the implementation of innovative bridge technologies assessment study and its application under the World Bank-funded Solomon Islands Roads and Aviation Project. This case study focused on the use of a selected range of modular bridges that provide a low maintenance, long-term, whole of life bridge solution which illustrates how the quality of infrastructure investment can be improved by improving economic efficiency and building resilience. It also outlines a way forward for the implementation of these bridge technologies across the Pacific region.
Supporting Road Network Vulnerability Assessments in Pacific Island Countries
(World Bank, Washington, DC, 2018-04) World Bank Group
In Pacific Island Countries, high vulnerability to the impacts of climate change and natural disasters means that such events can have devastating social and economic impacts when critical infrastructure is compromised. This has been apparent in countries where severe disruptions to road networks have resulted in a loss of access to basic infrastructure and services. Building resilience is therefore a prerequisite for long-term sustainable development, and Governments will increasingly seek tools that can help guide investment and policy decisions by considering the effects of climate change and natural disasters. Among such tools are road network vulnerability assessments, which provide a means to design and maintain a climate resilient network. This articlehighlights the process and lessons learned from the Vulnerability Assessment and Climate Resilient Road Strategy of the Samoan road network, and outlines a replicable approach for small island nations with acute capacity challenges that seek to balance analytical rigor with the need for practicality.
Notes on the Economic Evaluation of Transport Projects
(World Bank, Washington, DC, 2005-01) Mackie, Peter; Nellthorp, John; Laird, James
In response to many requests for help in the application of both conventional cost benefit analysis in transport and addressing of the newer topics of interest, we have prepared a series of Economic Evaluation Notes that provide guidance on some of issues that have proven more difficult to deal with. The Economic Evaluation Notes are arranged in three groups. The first group (TRN-6 to TRN-10) provides criteria for selection a particular evaluation technique or approach; the second (TRN-11 to TRN-17) addresses the selection of values of various inputs to the evaluation, and the third (TRN-18 to TRN-26) deals with specific problematic issues in economic evaluation. The Notes are preceded by a Framework (TRN-5), that provides the context within which we use economic evaluation in the transport sector. Economic evaluation involves the assessment of the net value of projects and policies. In the transport sector we value projects in terms of their net worth, the difference between the value of their benefits and their costs, both measured so far as is possible in terms of monetary units. This disarmingly simple statement leads to many questions; evaluation by whom, for whom, from what perspective, at what stage. One of the features of transport decisions is that they typically impact on many parties - transport operators, individual transport users, local residents and businesses, land and property owners, national and local taxpayers.
Evaluation of Public Sector Contributions to Public-Private Partnership Projects
(World Bank, Washington, DC, 2005-01) Mackie, Peter; Nellthorp, John; Laird, James
The Bank requires that any public sector contribution to a collaborative effort between the public sector and private enterprises in the transport sector be analyzed and justified in economic terms. This Note will set out the basis for making such an analysis. The general principles underlying this analysis are that: 1) public contributions to public-private partnership (PPP) projects should be justified on the basis of external benefits from the project, compared with the scenario where no public contribution is made. 2) these external benefits are benefits for the wider economy or society which will arise from the project, but which will not be appropriated by the private partner in the contract; 3) by implication, the social welfare gain must be greater than the amount of public money invested multiplied by the cost of public funds. In practice, a range of different reasons can be - and have been - put forward to explain public contributions to PPP projects, including the following: 1) to pay for positive externalities, such as decongestion or improvements in environmental quality; 2) to contribute to the cost of mitigating negative externalities, which private providers often have little incentive to take into account when designing the project; 3) to secure network improvements necessary for economic development or other planning benefits, for which users are in the short term unable to pay. These are considered one by one in Sections 2, 3, and 4.
