Publication: Procuring Pavement Management Data-Collection Services
Abstract
Data are the foundation for any successful pavement management system (PMS). Without appropriate and relevant data, the PMS cannot be used to make sensible decisions. As data-collection technologies become more sophisticated, the trend is. away from agencies conducting in-house data collection towards contracting out these services. For this to be effective, it is necessary for the agency to ensure that it has an appropriate specification, good contract management procedures, and a robust quality assurance framework. The World Bank, having financed data-collection. activities for a number of projects, has recently prepared a generic terms of reference for procuring data-collection services that reflects its experience in a number of countries (Mallela 2007). This paper summaries the key issues encountered by the Bank, and how they can be addressed in procuring data-collection services.

Publication Data Collection Technologies for Road Management(World Bank, Washington, DC, 2006-05)Different types of data are required for managing the road infrastructure. Inventory data describe the physical elements of a road system. Condition data describe the condition of elements that can be expected to change over time. There are a wide range of technologies available to the road manager for measuring attributes of the road network. The challenge is to select the appropriate equipment, given local conditions and the way in which the data are expected to be used. The purpose of this note is to give a general view of the currently available survey technologies applied to pavements, bridges and traffic. This includes an assessment of the applicability of these technologies in developing countries. The goal is to assist managers in establishing an appropriate and sustainable e data collection program and procuring the appropriate equipment to collect the data. This note is a summary of the report 'Data Collection Technologies for Road Management' (see report no. 37372). The note opens with a discussion of data collection requirements. This is then followed by separate discussions on pavements, bridges and traffic survey technologies. A cost/performance analysis between available equipment is presented in each section. Finally, recommendations for data collection are presented as a guidance to managers in developing countries.Publication Collecting High-Frequency Data Using Mobile Phones : Do Timely Data Lead to Accountability?(World Bank, Washington, DC, 2013-01)As mobile phone ownership rates have risen dramatically in Africa, there has been increased interest in using mobile telephones as a data collection platform. This note draws on two largely successful pilot projects in Tanzania and South Sudan that used mobile phones for high-frequency data collection. Data were collected on a wide range of topics and in a manner that was cost-effective, flexible, and rapid. Once households were included in the survey, they tended to stick with it: respondent fatigue has not been a major issue. While attrition and nonresponse have been challenges in the Tanzania survey, these were due to design flaws in that particular survey, challenges that can be avoided in future similar projects. Ensuring use of the data to demand better service delivery and policy decisions turned out to be as challenging as collecting the high-quality data. Experiences in Tanzania suggest that good data can be translated into public accountability, but also demonstrate that just putting data out in the public domain is not enough. This note discusses lessons learned and offers suggestions for future applications of mobile phone surveys in developing countries, such as those planned for the World Bank's "Listening to Africa" initiative.Publication Success Factors for Road Management Systems(World Bank, Washington, DC, 2006-02)Over the last 20 years most road agencies have implemented some form of computerized road management system (RMS). The purpose of these systems is to assist the road agency in the planning and prioritization of road investments. While some systems have been successful, there have also been many which have failed in one or more areas. This is in spite of large investments of time and money. While it is often easy to identify the symptoms of failure, the causes are often complex and multi-layered. However, for every failed system, there is a more successful implementation somewhere in the world, in an agency that often suffers from similar problems and constraints. This Note describes the different factors associated with successful RMS implementations. It is a summary of the report Success Factors for Road Management Systems.Publication Sustainably Managing Natural Resources and the Need for Construction Materials in Pacific Island Countries : The Example of South Tarawa, Kiribati(Wiley, 2014-02)The growing demand for construction materials in South Tarawa, a remote atoll in the South Pacific, provides an example of the environmental and social challenges associated with the use of non-renewable resources in the context of small island countries threatened by coastal erosion and climate change. In many small Pacific island countries, the availability of construction materials is limited, with the majority mined from beaches and coastal reefs in an unsustainable manner. Growing demand for construction aggregates is resulting in more widespread sand mining by communities along vulnerable sections of exposed beach and reefs. This has serious consequences for coastal erosion and impacts on reef ecosystem processes, consequences that cannot be easily managed. Construction materials are also in high demand for infrastructure projects which are financed in part with support from international development agencies and donors. This paper reviews the various challenges and risks that aggregate mining poses to reefs, fish, and the coastal health of South Tarawa and argues that the long term consequences from ad hoc beach/reef mining over large areas are likely to be far greater than the impacts associated with environmentally sustainable, organized extraction. The paper concludes with policy recommendations that are also relevant for neighboring island countries facing similar challenges.Publication Collecting High Frequency Panel Data in Africa Using Mobile Phone Interviews(World Bank, Washington, DC, 2012-06)As mobile phone ownership rates have risen in Africa, there is increased interest in using mobile telephony as a data collection platform. This paper draws on two pilot projects that use mobile phone interviews for data collection in Tanzania and South Sudan. The experience was largely a success. High frequency panel data have been collected on a wide range of topics in a manner that is cost effective, flexible (questions can be changed over time) and rapid. And once households respond to the mobile phone interviews, they tend not to drop out: even after 33 rounds of interviews in the Tanzania survey, respondent fatigue proved not to be an issue. Attrition and non-response have been an issue in the Tanzania survey, but in ways that are related to the way this survey was originally set up and that are fixable. Data and reports from the Tanzania survey are available online and can be downloaded from: www.listeningtodar.org.
